Definitions
- the present invention relates to the encapsulation of an active agent which comprises a milk saccharide or a mixture of at least two different milk saccharides, wherein said saccharide and said saccharides are obtained from an in vitro and/or ex vivo culture of cells. More specifically, the present invention relates to the encapsulation of an active agent which comprises a milk oligosaccharide or a mixture of at least two different milk oligosaccharides, wherein said milk oligosaccharide and said milk oligosaccharides are obtained from an in vitro and/or ex vivo culture of cells.
- oligosaccharides are gaining more and more attention.
- This molecule group is very diverse in chemical structure, and are composed out of a diverse number of monosaccharides, such as glucose, galactose, N-acetylglucosamine, xylose, rhamnose, N- acetylneuraminic acid, N-acetylgalactosamine, galactosamine, glucosamine, glucuronic acid, galacturonic acid,...
- These oligosaccharides or glycans are macromolecules in nature with a range of important biological activities and widely distributed in all living organisms.
- These oligosaccharides or glycans play important roles in a variety of normal physiological and pathological processes, such as cell metastasis, signal transduction, intercellular adhesion, inflammation and immune response.
- milk saccharides are milk saccharides (Urashima T. et al., 2011, Milk Oligosaccharides, Nova Biomedical Books, New York ISBN 978-1-61122-831-1; Coppa et al, 2013, Ital. J. Pediatr. 2013, 39(2)), in particular milk oligosaccharides (MOs), i.e. (oligo)saccharides which are found in milk of animals such as mammals and humans (Urashima et al, 2011; Coppa et al, 2013). A replete amount of milk saccharide structures have been elucidated so far.
- MOs milk oligosaccharides
- milk oligosaccharides found in animals such as mammals and humans comprise lactose at the reducing end (Urashima et al, 2011).
- Other milk oligosaccharides comprise N-acetyllactosamine (Gal-pi,4-GlcNAc) or lacto-N-biose (Gal-pi,3-GlcNAc) at the reducing end (Urashima et al, 2011; Wrigglesworth et al, 2020, PLoS ONE 15(12); Urashima et al, 2013, Biosci. Biotechnol. Biochem 77(3): p. 455-466; Wei et al, 2018, Sci. Rep. 8:4688).
- Examples hereof are 3- FLN (Gal-pi,4-(Fuc-al,3-)GlcNAc; also known as Lewis x antigen), 3'-SLN (Neu5Ac-a2,3-Gal-pi,4-GlcNAc), 6'-SLN (Neu5Ac-a2,6-Gal-pi,4-GlcNAc) (Urashima et al, 2011; Wrigglesworth et al, 2020; Wei et al, 2018). Further, milk saccharides comprise milk glycosaminoglycans (GAGs; Coppa et al, 2013; Rai et al, 2021, Int. J. Biol.
- Antigens of the human ABO blood group system such as the A determinant (GalNAc-alphal,3(Fuc-alphal,2)-Gal), B determinant (Gal-alphal,3(Fuc-alphal,2)-Gal) and H-determinant (Fuc-alphal,2-Gal) have been shown to be present in saccharides of the milk of mammals (e.g. A tetrasaccharide in a lion and leopard; Wrigglesworth et al, 2020). Such milk, more specifically, human milk is to date considered as the best food for newborns and infants.
- HMOs and MMOs are further known to act as decoys to reduce the risk of infections by bacterial and viral pathogens which adhere to human cells by binding to these cells' surface glycoproteins. Additionally, various HMOs and MMOs possess an anti-inflammatory effect and act as immunomodulators (e.g. reducing the risk of developing food allergies). Altogether, these beneficial effects make milk oligosaccharides, especially mammalian (MMOs) and human milk oligosaccharides (HMOs), promising candidates to incorporate into food and feed.
- MMOs mammalian
- HMOs human milk oligosaccharides
- Saccharides especially oligosaccharides such as mammalian and human milk oligosaccharides, are in most cases chemically reactive molecules and/or labile under certain conditions (e.g. high temperature, low or high pH, and/or high moisture content). They are redox- and also biologically active, sensitive to mechanical stress (e.g. excessive shear) and in addition temperature sensitive. Furthermore, dissolved oligosaccharides can react chemically by oxidative or reductive conditions.
- said oligosaccharides can undergo intra- and intermolecular substitutions and hydrolysis reactions rendering the oligosaccharides labile, which in extreme cases may even lead to isomerization or disintegration and coloration of the end product, by for example, the formation of an isomer form at the reducing end of the oligosaccharide or the formation of hydroxymethylfurfural (HMF), which is a well-known sugar decomposition product in literature, occurring when applying too basic, too acidic and/or too hot conditions (Cammerer et al., 1999, Eur. Food Res. Technol. 1999, 209(3-4), 261-265; Fagerson, 1969, J. Agric. Food Chem.
- HMF hydroxymethylfurfural
- milk saccharides especially milk oligosaccharides such as MMOs and HMOs
- conditions relating to the manufacturing or storing of food and feed may have a negative impact on the oligosaccharides considering their properties as outlined earlier.
- Such conditions typically entail a high pressure (e.g. a pressure of above 10 bar during extrusion), a high temperature (e.g. a temperature above 100°C during extrusion and baking), a pH lower than 5, a pH higher than 8, and/or a high moisture content.
- a high pressure e.g. a pressure of above 10 bar during extrusion
- a high temperature e.g. a temperature above 100°C during extrusion and baking
- a pH lower than 5 e.g. a temperature above 100°C during extrusion and baking
- pH lower than 5 e.g. a temperature above 100°C during extrusion and baking
- pH lower than 5 e.g. a temperature above 100°C during extrusion and baking
- protecting saccharides is also of particular importance in feeding conditions, for example if they are incorporated into aquaculture feed as the feed remains in contact with water for a prolonged time (few minutes for instant feeders such as trout and catfish, up to a few hours for shrimp for example) until consumed by the animal.
- a prolonged time for instant feeders such as trout and catfish, up to a few hours for shrimp for example
- protecting saccharides is also of particular importance in feeding conditions, for example if they are incorporated into aquaculture feed as the feed remains in contact with water for a prolonged time (few minutes for instant feeders such as trout and catfish, up to a few hours for shrimp for example) until consumed by the animal.
- a liquid such as water
- protecting saccharides, especially oligosaccharides such as MMOs and HMOs
- encapsulating milk saccharides serves a great strategy to overcome aforementioned issues by reducing and/or avoiding contact with other components and retaining the milk saccharides despite exposure to conditions which would otherwise affect the milk saccharides such as a high pressure, high temperature, high moisture content (e.g. contact with water), pH which is lower than 5 or higher than 8, etc. as described further herein.
- the invention provides an encapsulate comprising (i) an active agent comprising a milk saccharide or a mixture of at least two different milk saccharides, and (ii) a first carrier material, wherein said saccharide and said saccharides are obtained from an in vitro and/or ex vivo culture of cells.
- the invention provides a method for the production of an encapsulated active agent comprising a milk saccharide or a mixture of at least two different milk saccharides, wherein said saccharide and said saccharides are obtained from an in vitro and/or ex vivo culture of cells.
- the invention provides a composition, preferably a nutritional composition, comprising an encapsulate according to the first aspect or comprising an encapsulated active agent obtainable by a method according to the second aspect.
- the invention provides a pharmaceutical composition comprising an encapsulate according to the first aspect or comprising an encapsulated active agent obtainable by a method according to the second aspect.
- the invention provides an encapsulate (first aspect), encapsulated active agent (second aspect), nutritional composition (third aspect) or pharmaceutical composition (fourth aspect) for use as a medicament.
- the invention provides a method for the production of a composition, preferably a nutritional composition and/or a pharmaceutical composition.

- the term "flowability” refers to the relative movement of a bulk of particles among neighboring particles or along the container wall surface. Flowability cannot be determined by a simple test method. Good indicators of flowability of particles are the Hausner Ratio (Rh) and Carr index (l c ), both indicators assume that the compressibility of a particle/solid relates to its flowability.
- the term "bulk density” is the weight of the particles of a particulate solid (such as a powder) in a given volume, and is expressed in grams per liter (g/L).
- the total volume that the particles of a particulate solid occupy depends on the size of the particles themselves and the volume of the spaces between the particles. Entrapped air between and inside the particles also can affect the bulk density. Thus a particulate solid consisting of large, porous particles with large inter-particulate spaces will have a lower bulk density than a particulate solid consisting of small, non-porous particles that compact closely together. Bulk density can be expressed in two forms: loose bulk density and tapped bulk density. "Loose bulk density" (also known in the art as “freely settled” or "poured” bulk density) is the weight of a particulate solid divided by its volume where the particulate solid has been allowed to settle into that volume of its own accord (e.g. a powder poured into a container).
- Tapped bulk density is the weight of a particulate solid divided by its volume where the particulate solid has been tapped and allowed to settle into the volume a precise number of times. The number of times the particulate solid has been tapped is typically when stating the tapped bulk density.
- “lOOx tapped bulk density” refers to the bulk density of the particulate solid after it has been tapped 100 times. Techniques for measuring bulk density are well known in the art.
- Loose bulk density may be measured using a measuring cylinder and weighing scales: the particulate solid is poured into the measuring cylinder and the weight and volume of the particulate solid; weight divided by volume gives the loose bulk density.
- Tapped bulk density can be measured using the same technique, with the addition of tapping the measuring cylinder a set number of times before measuring weight and volume. Automation of tapping ensures the number, timing and pressure of individual taps is accurate and consistent. Automatic tapping devices are readily available, an example being the Jolting Stampfvolumeter (STAV 203) from J. Englesmann AG.
- the encapsulates according to the invention as described herein have a good to excellent flowability, whereas the flowability of the non-encapsulated saccharide or non-encapsulated mixture of saccharides, preferably non-encapsulated active agent, is poor.
- a poor, good or excellent flowability can be characterized by a Carr index and/or Hausner ratio as depicted in Table 1.
- a predictable and good/excellent flowability is of great importance to achieve better manufacturing efficiency and product quality.
- An irregular and/or poor flowability can result in capacity shortfall and production interruption.
- the food industry makes extensive use of vertical bins/silos for powder storage. Irregular and/or poor flow of powders out of those is a major cause of loss in production capacity and product deterioration.
- an irregular and/or poor flowability can affect manufacturing efficiency and hence affect the weight and content uniformity (i.e. quality) of the product.

Description
Encapsulated milk saccharides
Field of the invention
The present invention relates to the encapsulation of an active agent which comprises a milk saccharide or a mixture of at least two different milk saccharides, wherein said saccharide and said saccharides are obtained from an in vitro and/or ex vivo culture of cells. More specifically, the present invention relates to the encapsulation of an active agent which comprises a milk oligosaccharide or a mixture of at least two different milk oligosaccharides, wherein said milk oligosaccharide and said milk oligosaccharides are obtained from an in vitro and/or ex vivo culture of cells.
Background of the invention
To date saccharides and especially oligosaccharides are gaining more and more attention. This molecule group is very diverse in chemical structure, and are composed out of a diverse number of monosaccharides, such as glucose, galactose, N-acetylglucosamine, xylose, rhamnose, N- acetylneuraminic acid, N-acetylgalactosamine, galactosamine, glucosamine, glucuronic acid, galacturonic acid,... These oligosaccharides or glycans are macromolecules in nature with a range of important biological activities and widely distributed in all living organisms. These oligosaccharides or glycans play important roles in a variety of normal physiological and pathological processes, such as cell metastasis, signal transduction, intercellular adhesion, inflammation and immune response.
An example of such saccharides are milk saccharides (Urashima T. et al., 2011, Milk Oligosaccharides, Nova Biomedical Books, New York ISBN 978-1-61122-831-1; Coppa et al, 2013, Ital. J. Pediatr. 2013, 39(2)), in particular milk oligosaccharides (MOs), i.e. (oligo)saccharides which are found in milk of animals such as mammals and humans (Urashima et al, 2011; Coppa et al, 2013). A replete amount of milk saccharide structures have been elucidated so far. The majority of milk oligosaccharides found in animals such as mammals and humans comprise lactose at the reducing end (Urashima et al, 2011). Other milk oligosaccharides comprise N-acetyllactosamine (Gal-pi,4-GlcNAc) or lacto-N-biose (Gal-pi,3-GlcNAc) at the reducing end (Urashima et al, 2011; Wrigglesworth et al, 2020, PLoS ONE 15(12); Urashima et al, 2013, Biosci. Biotechnol. Biochem 77(3): p. 455-466; Wei et al, 2018, Sci. Rep. 8:4688). Examples hereof are 3- FLN (Gal-pi,4-(Fuc-al,3-)GlcNAc; also known as Lewis x antigen), 3'-SLN (Neu5Ac-a2,3-Gal-pi,4-GlcNAc), 6'-SLN (Neu5Ac-a2,6-Gal-pi,4-GlcNAc) (Urashima et al, 2011; Wrigglesworth et al, 2020; Wei et al, 2018). Further, milk saccharides comprise milk glycosaminoglycans (GAGs; Coppa et al, 2013; Rai et al, 2021, Int. J. Biol. Macromolecules, 193(A): p. 137-144). Antigens of the human ABO blood group system such as the A determinant (GalNAc-alphal,3(Fuc-alphal,2)-Gal), B determinant (Gal-alphal,3(Fuc-alphal,2)-Gal) and H-determinant (Fuc-alphal,2-Gal) have been shown to be present in saccharides of the milk of mammals (e.g. A tetrasaccharide in a lion and leopard; Wrigglesworth et al, 2020).
Such milk, more specifically, human milk is to date considered as the best food for newborns and infants. It is composed of several fractions of which milk oligosaccharides are the fourth largest fraction. Besides lactose, human milk, as well as milk of other mammals, contains various structurally diverse oligosaccharides which are also known as human milk oligosaccharides (HMOs) or mammalian milk oligosaccharides (MMOs), respectively (Urashima T. et al., 2011). The importance of MOs for mammalian and human infant nutrition is directly linked to their biological activities including protection of the neonate from pathogens, supporting development of the infant's immune system and cognitive abilities. HMOs and MMOs are further known to act as decoys to reduce the risk of infections by bacterial and viral pathogens which adhere to human cells by binding to these cells' surface glycoproteins. Additionally, various HMOs and MMOs possess an anti-inflammatory effect and act as immunomodulators (e.g. reducing the risk of developing food allergies). Altogether, these beneficial effects make milk oligosaccharides, especially mammalian (MMOs) and human milk oligosaccharides (HMOs), promising candidates to incorporate into food and feed.
Saccharides, especially oligosaccharides such as mammalian and human milk oligosaccharides, are in most cases chemically reactive molecules and/or labile under certain conditions (e.g. high temperature, low or high pH, and/or high moisture content). They are redox- and also biologically active, sensitive to mechanical stress (e.g. excessive shear) and in addition temperature sensitive. Furthermore, dissolved oligosaccharides can react chemically by oxidative or reductive conditions. Moreover, said oligosaccharides can undergo intra- and intermolecular substitutions and hydrolysis reactions rendering the oligosaccharides labile, which in extreme cases may even lead to isomerization or disintegration and coloration of the end product, by for example, the formation of an isomer form at the reducing end of the oligosaccharide or the formation of hydroxymethylfurfural (HMF), which is a well-known sugar decomposition product in literature, occurring when applying too basic, too acidic and/or too hot conditions (Cammerer et al., 1999, Eur. Food Res. Technol. 1999, 209(3-4), 261-265; Fagerson, 1969, J. Agric. Food Chem. 17(4), 747-750; Wilson, K. et al., 2014, Chapter 19, Bio-based chemicals from biorefining: carbohydrate conversion and utilization, 624-658, In Waldron, K. (Editor), Advances in Biorefineries: Biomass and Waste Supply Chain Exploitation, ISBN: 978-0-85709-521-3; Van der Fels-Klerx, H. J. et al., 2014, Food Res. Int. 57, 210-217).
Although the incorporation of milk saccharides, especially milk oligosaccharides such as MMOs and HMOs into food and feed might be promising, conditions relating to the manufacturing or storing of food and feed may have a negative impact on the oligosaccharides considering their properties as outlined earlier. Such conditions typically entail a high pressure (e.g. a pressure of above 10 bar during extrusion), a high temperature (e.g. a temperature above 100°C during extrusion and baking), a pH lower than 5, a pH higher than 8, and/or a high moisture content. Moreover, other molecules within food or feed such as proteins could chemically interact with MMOs and HMOs especially under the harsh conditions during food/feed manufacturing. There is hence a significant need for protecting saccharides, especially oligosaccharides
such as MMOs and HMOs, during food/feed manufacture and storage to ensure their retention in the final food and feed.
Furthermore, protecting saccharides, especially oligosaccharides such as MMOs and HMOs, is also of particular importance in feeding conditions, for example if they are incorporated into aquaculture feed as the feed remains in contact with water for a prolonged time (few minutes for instant feeders such as trout and catfish, up to a few hours for shrimp for example) until consumed by the animal. Not only the physical integrity of the aquaculture feed while in contact with water is crucial, but also of paramount importance is to reduce leaching of incorporated substances such as said saccharides. Also here there is a significant need for protecting saccharides, especially oligosaccharides such as MMOs and HMOs, from contact with a liquid such as water, e.g. protecting saccharides, especially oligosaccharides such as MMOs and HMOs, in aquaculture feed to reduce leaching into the water and hence obtain an aquaculture feed with a high pellet water stability.
Summary of the invention

Detailed description of the invention
Encapsulate
In a first aspect, the invention provides an encapsulate comprising: an active agent comprising a milk saccharide or a mixture of at least two different milk saccharides, preferably said active agent comprising a milk oligosaccharide or a mixture of at least two different milk oligosaccharides, wherein said saccharide, preferably oligosaccharide, and said saccharides, preferably oligosaccharides, are obtained from an in vitro and/or ex vivo culture of cells, and a first carrier material which forms (i) a shell around said active agent as to form an encapsulate of the core-shell type or (ii) a matrix wherein said active agent is distributed as to form an encapsulate of the matrix type, preferably said first carrier material forms a shell around said active agent as to form an encapsulate of the core-shell type.
In the context of the present invention, an "encapsulate" comprises a substance that is encapsulated, i.e. said substance is coated and/or trapped in a carrier material. In the field of (micro)encapsulation, the substance that is encapsulated is typically called an "active agent", "internal phase" or "payload phase", these terms are hence used interchangeably herein. The substance that is encapsulating the active agent is typically called "carrier material", "wall material", "external phase", "encapsulant" or "matrix", these terms are hence used interchangeable herein.
As known in the field of (micro)encapsulation, there are generally two main types of encapsulates.
A first type of encapsulate contains a shell around the active agent (i.e. the core of the encapsulate), i.e. the carrier material forms a shell around the active agent. This type of encapsulate is generally referred to as "core-shell type", "(micro)capsule", "single-core" or "mono-core", said terms are used interchangeably herein. The core can be either liquid or solid. As soon as the carrier material (i.e. the shell) partially encapsulates the active agent (i.e. the core), it is considered to be a core-shell-type encapsulate in the context of the present invention and hence within the scope of the present invention. It is however
a preferred embodiment of the present invention that the carrier material completely encapsulates the active agent.
A second type of encapsulate is generally referred to as "matrix type" or "microsphere", said terms are used interchangeably herein. Herein, the active agent is dispersed in a continuous network of the carrier material. The active agent can be present for example as small microparticles or droplets, or more homogeneously distributed over the encapsulate. An encapsulate of the matrix type is a solid matrix particle, wherein the active agent is typically dissolved/dispersed or melted in it.
The skilled person will readily understand that an encapsulate of the matrix type can be further coated as to form a so-called "coated matrix type", which is essentially a core-shell type of encapsulate wherein the solid core consists of the active agent dissolved/dispersed into carrier material. In the context of the invention, a coated matrix type of encapsulate is considered to be a core-shell type of encapsulate, unless specifically stated otherwise.
In the context of the present invention, "a matrix wherein said active agent is distributed as to form an encapsulate of the matrix type" refers to the situation wherein the active agent is dissolved or dispersed into the carrier material, either heterogeneously or homogeneously (homogeneously is preferred but not essential in the context of the present invention). The term "distributed" can hence be interchangeably used with the term "dispersed". The term "dissolved" refers to the situation wherein the active agent is incorporated into a liquid or melt so as to form a solution and therefore represents an example of dispersion. The skilled person will readily understand that the term "dispersion" not only encompasses the situation wherein the active agent is dissolved into a carrier material, but also the situation wherein the active agent and carrier material form a suspension.
In a preferred embodiment, the encapsulate according to the invention is a microparticle, preferably a spherical microparticle. Preferably, said encapsulate has an aspect ratio of 0.8-1.2, more preferably an aspect ratio of 0.9-1.1. In the context of the present invention, the term "aspect ratio" preferably means the ratio between the length and width of a particle. The encapsulates according to the invention preferably have a regular symmetry, i.e. having an aspect ratio which lies in the range of 0.8-1.2, preferably 0.9-1.1. A "microparticle" is a particle having a physical dimension of 1 to 1000 micrometer, preferably < 750 pm, more preferably < 600 pm. A microparticle may or may not be spherical in shape.
In an additional and/or alternative preferred embodiment, the encapsulate according to the invention has a median diameter (D50 also known as D(v, 0.5)) of at least 50 pm, preferably at least 75 pm, more preferably at least 100 pm, even more preferably at least 125 pm, even more preferably at least 150 pm, most preferably at least 175 pm; and/or said encapsulate has a median diameter (D50 also known as D (v, 0.5)) of < 400 pm, preferably < 350 pm, more preferably < 300 pm. Throughout the description and
claims, the terms "D50" and "D(v,0.5)" can be interchangeably used. In the context of the present invention, "D(v,0.5)" also known as the volume median diameter is the diameter of a particle where 50 % of the distribution is above and 50% is below. Several techniques are available to determine the size of a particle such as laser diffraction, dynamic light scattering, automated imaging, sedimentation, electrozone sensing and sieving. Each technique has a particle size range wherein it can be applied. In the context of the present invention, laser diffraction is preferred to assess the size of a particle and hence to determine the D(v,0.1), D(v,0.5), D(v,0.9) and D(4,3) of an encapsulate/particle as defined herein. A particularly suitable system for laser diffraction is a MasterSizer S apparatus from Malvern Instruments Ltd.
When an encapsulate according to the invention is of the core-shell type, it is a preferred embodiment that the core (preferably an encapsulate of the matrix type) has a median diameter (D50 also known as D(v, 0.5)) of at least 50 pm, preferably at least 75 pm, more preferably at least 100 pm, even more preferably at least 125 pm, even more preferably at least 150 pm, most preferably at least 165 pm. Preferably, said median diameter is 75-250 pm, more preferably 100-250 pm, even more preferably 125- 250 pm, even more preferably 150-250 pm, even more preferably 165-250 pm, most preferably 165-225 pm. In an additional and/or alternative preferred embodiment in this context (i.e. when said encapsulate is of the core-shell type), the core-shell type encapsulate has a median diameter (D50 also known as D(v, 0.5)) which is 10-100 pm, preferably 20-100 pm, more preferably 20-75 pm, even more preferably 35-75 pm, longer than the median diameter of the core (preferably an encapsulate of the matrix type). In an additional and/or alternative preferred embodiment in this context (i.e. when said encapsulate is of the core-shell type), the core-shell type encapsulate has a median diameter (D50 also known as D(v, 0.5)) which is 10%-40%, preferably 10%-35%, more preferably 10%-30%, even more preferably 15%-30%, most preferably 20%-30%, longer than the median diameter of the core (preferably an encapsulate of the matrix type).
In an additional and/or alternative preferred embodiment, the encapsulate according to the invention has a D(4,3) of at least 50 pm, preferably at least 75 pm, more preferably at least 100 pm, even more preferably at least 125 pm, even more preferably at least 150 pm, most preferably at least 175 pm; and/or said encapsulate has a D(4,3) of < 400 pm, preferably < 350 pm, more preferably < 300 pm. throughout the description and claims, the terms "D(4,3)" and "De Brouckere mean diameter" can be interchangeably used. In the context of the present invention, "D(4,3)" refers to the mean of a particle size distribution weighted by the volume and is also known as the volume-weighted mean diameter.
In additional and/or alternative preferred embodiment, the encapsulate according to the invention has a particle size distribution characterized by:
D(v, 0.1) ranging from 35 to 200 pm, preferably from 50 to 200 pm, more preferably 75 to 200 pm; and/or
D(v, 0.5) ranging from 50 to 400 pm, preferably from 50 to 350 pm, more preferably from 100 to 350 pm, even more preferably from 125 to 350 pm, even more preferably form 150 pm to 350 pm, even more preferably from 175 to 300 pm; and/or
D(v, 0.9) ranging from 100 to 600 pm, preferably from 100 to 500 pm, more preferably from 150 to 500 pm, even more preferably from 200 to 500 pm, even more preferably from 250 to 500 pm, most preferably from 300 to 500 pm; and/or
D(4,3) ranging from 50 to 400 pm, preferably from 50 to 350 pm, more preferably from 100 to 350 pm, even more preferably from 125 to 350 pm, even more preferably form 150 pm to 350 pm, even more preferably from 175 to 325 pm; and/or a span of 0.75-1.3, preferably 0.75-1.25, more preferably 0.85-1.25, even more preferably 0.9-1.25, most preferably 0.9-1.2, wherein said span is calculated as (D(v,0.9) - D(v,0.1)) / D(v,0.5).
In the context of the present invention, "D(v,0.1)" refers to the diameter of a particle where 10 % of the volume distribution is below; "D(v,0.9)" refers to the diameter of a particle where 90 % of the volume distribution is below. "Span" refers to the width of the particle size distribution based on the 10 %, 50 % and 90 % quantile, i.e. span = (D(v,0.9) - D(v,0.1)) / D(v,0.5).
Advantageously, the encapsulates according to the invention have a homogeneous size distribution as the span is in the range of 0.9-1.2.
In additional and/or alternative preferred embodiment, the encapsulate according to the invention has a moisture content, preferably water content, of < 15 % (VJ/VJ), preferably < 10 % (VJ/VJ), more preferably < 9 % (VJ/VJ), even more preferably < 8 % (VJ/VJ), even more preferably < 7 % (VJ/VJ), even more preferably < 5 % (VJ/VJ), even more preferably < 4 % VJ/VJ), even more preferably < 3 % (VJ/VJ), most preferably < 2 % (VJ/VJ), of the total weight of the composition. In other words, the encapsulate according to the invention has a dry extract (% (w/w)) of at least 85 %, preferably at least 90 %, more preferably at least 91 %, even more preferably at least 92 %, even more preferably at least 93 %, even more preferably at least 95 %, even more preferably at least 96 %, even more preferably at least 97 %, most preferably at least 98%, preferably as determined by a thermogravimetric analysis or Karl Fisher titration analysis, more preferably as determined by a thermogravimetric analysis. The moisture content (preferably water content) can be determined gravimetrically as routinely applied in the field by drying the sample (i.e. encapsulate according to the invention) at 105°C up to a constant weight is obtained, preferably said sample is dried for 24 hours at 105°C (e.g. Hernandez-Lopez et al, 2018, LWT 2018, 95: p. 216-222; Pang et al, 2017, J. Food Quality, article id 1612708). Hence, said % dry extract is preferably calculated as (mass of encapsulate after 24 hours at 105°C / initial mass of the encapsulate) x 100.
In this context of the invention, the term "moisture content" can be preferably replaced with "liquid content" and vice versa, unless explicitly stated otherwise.
In additional and/or alternative preferred embodiment, the encapsulate according to the invention has a water activity (Aw) which is higher than the water activity of the non-encapsulated saccharide or nonencapsulated mixture of saccharides, preferably the non-encapsulated active agent. In other words, the water activity of the saccharide or mixture of at least two saccharides as disclosed herein (nonencapsulated, i.e. in the absence of any carrier material, and preferably provided as powder), preferably the active agent as disclosed herein (non-encapsulated, i.e. in the absence of any carrier material, and preferably provided as powder), is lower than the water activity of the encapsulate according to the invention which comprises an identical saccharide or mixture of saccharides, preferably an identical active agent.
In additional and/or alternative preferred embodiment, the encapsulate according to the invention has a water activity (Aw) which is at least 0.05, preferably at least 0.075, more preferably at least 0.10, even more preferably at least 0.15, most preferably which is at least 0.16 and/or wherein said encapsulate has a water activity of < 0.50, preferably < 0.45, more preferably < 0.40, even more preferably < 0.35, most preferably < 0.30. Preferably, the encapsulate according to the invention has a water activity (Aw) which is 0.05-0.50, preferably 0.05-0.45, more preferably 0.05-0.40, even more preferably 0.05-0.35, even more preferably 0.05-0.30, even more preferably 0.10-0.30, even more preferably 0.15-0.30, most preferably 0.16-0.30. The skilled person will readily understand that the water activity has to be determined using an identical (or at least substantially the same) method and under identical (or at least substantially the same) conditions. In the context of the present invention, the term "water activity (Aw)" refers to the dimensionless ratio between the vapor pressure of water in the encapsulate and the vapor pressure of pure water at the same temperature. Hence, the activity water level reflects the thermodynamic energy status of the water in the encapsulate, ranging from Oto 1.00. Preferably, said water activity is determined at ambient temperature, more preferably at a temperature of 24.5-24.9°C. Preferably, said water activity is determined by a LabSwift-aw system (preferably from Novasina).
In additional and/or alternative preferred embodiment, the encapsulate according to the invention has a flowability which is higher than the flowability of the non-encapsulated saccharide or non-encapsulated mixture of saccharides, preferably the non-encapsulated active agent. In other words, the flowability of the saccharide or mixture of at least two saccharides as disclosed herein (non-encapsulated, i.e. in the absence of any carrier material, and preferably provided as powder), preferably the flowability of the active agent as disclosed herein (non-encapsulated, i.e. in the absence of any carrier material, and preferably provided as powder), is lower than the flowability of the encapsulate according to the invention which comprises an identical saccharide or mixture of saccharides, preferably which comprises an identical active agent. The skilled person will readily understand that the flowability has to be determined
using an identical (or at least substantially the same) method and under identical (or at least substantially the same) conditions. In the context of the present invention, the term "flowability" refers to the relative movement of a bulk of particles among neighboring particles or along the container wall surface. Flowability cannot be determined by a simple test method. Good indicators of flowability of particles are the Hausner Ratio (Rh) and Carr index (lc), both indicators assume that the compressibility of a particle/solid relates to its flowability. The "Hausner Ratio (Rh)" can be calculated by taking the ratio between the tapped density (pt) and bulk density (pb), i.e. Rh = pt / Pb- The "Carr index (lc)" can be calculated as follows: lc = ((pt - pb) / Pb) x 100. The lower the Carr Index or Hausner Ratio of an encapsulate/particle/solid is, the more flowable said encapsulate/particle/solid is. As used herein, the term "bulk density" is the weight of the particles of a particulate solid (such as a powder) in a given volume, and is expressed in grams per liter (g/L). The total volume that the particles of a particulate solid occupy depends on the size of the particles themselves and the volume of the spaces between the particles. Entrapped air between and inside the particles also can affect the bulk density. Thus a particulate solid consisting of large, porous particles with large inter-particulate spaces will have a lower bulk density than a particulate solid consisting of small, non-porous particles that compact closely together. Bulk density can be expressed in two forms: loose bulk density and tapped bulk density. "Loose bulk density" (also known in the art as "freely settled" or "poured" bulk density) is the weight of a particulate solid divided by its volume where the particulate solid has been allowed to settle into that volume of its own accord (e.g. a powder poured into a container).
Closer compaction of a particulate solid within a container may be achieved by tapping the container and allowing the particles to settle more closely together, thereby reducing volume while weight remains the same. Tapping therefore increases bulk density. "Tapped bulk density" (also known in the art as "tamped" bulk density) is the weight of a particulate solid divided by its volume where the particulate solid has been tapped and allowed to settle into the volume a precise number of times. The number of times the particulate solid has been tapped is typically when stating the tapped bulk density. For example, "lOOx tapped bulk density" refers to the bulk density of the particulate solid after it has been tapped 100 times. Techniques for measuring bulk density are well known in the art. Loose bulk density may be measured using a measuring cylinder and weighing scales: the particulate solid is poured into the measuring cylinder and the weight and volume of the particulate solid; weight divided by volume gives the loose bulk density. Tapped bulk density can be measured using the same technique, with the addition of tapping the measuring cylinder a set number of times before measuring weight and volume. Automation of tapping ensures the number, timing and pressure of individual taps is accurate and consistent. Automatic tapping devices are readily available, an example being the Jolting Stampfvolumeter (STAV 203) from J. Englesmann AG.
Advantageously, the encapsulates according to the invention as described herein have a good to excellent
flowability, whereas the flowability of the non-encapsulated saccharide or non-encapsulated mixture of saccharides, preferably non-encapsulated active agent, is poor. A poor, good or excellent flowability can be characterized by a Carr index and/or Hausner ratio as depicted in Table 1.
A predictable and good/excellent flowability is of great importance to achieve better manufacturing efficiency and product quality. An irregular and/or poor flowability can result in capacity shortfall and production interruption. For example, the food industry makes extensive use of vertical bins/silos for powder storage. Irregular and/or poor flow of powders out of those is a major cause of loss in production capacity and product deterioration. Also in the pharmaceutical industry, an irregular and/or poor flowability can affect manufacturing efficiency and hence affect the weight and content uniformity (i.e. quality) of the product.
In this regard, an encapsulate according to the invention wherein the carrier material comprises a wax (it is referred to the section entitled "Carrier material"), preferably selected from Candelilla wax, Carnauba wax, beeswax, rice bran wax, paraffin wax, jojoba wax, microcrystalline wax and japan wax, more preferably said wax is Candelilla wax, is particularly preferred as these encapsulates exert an excellent flowability. Such an encapsulate can be of the matrix type or core-shell type. As already depicted herein, an encapsulate of the so-called coated matrix type (in the present context, at least the carrier material of the shell comprises said wax, optionally the carrier material of the core comprises said wax) is also considered to be a core-shell type of encapsulate.
In additional and/or alternative preferred embodiment, the encapsulate according to the invention has a Hausner ratio (Rh) which is < 1.34, preferably < 1.25, more preferably < 1.18. In an additional and/or alternative preferred embodiment, the encapsulate according to the invention has a Carr index (lc) which is < 25, preferably < 20, more preferably < 15.
In additional and/or alternative preferred embodiment, the quantity and/or quality of said milk saccharide
or mixture of at least two different milk saccharides, preferably said active agent, of an encapsulate according to the invention is less affected upon (i.e. after) short and/or prolonged exposure to conditions compared to non-encapsulated milk saccharide or non-encapsulated mixture of at least two different milk saccharides, preferably compared to the non-encapsulated active agent. In other words, the quantity and/or quality of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as disclosed herein (non-encapsulated, i.e. in the absence of any carrier material, and preferably provided as powder), is more prone to said conditions than that of the encapsulate according to the invention which comprises an identical milk saccharide or mixture of milk saccharides, preferably an identical active agent. In the context of the present invention, the expressions "is more prone" and "is more affected" are preferably interchangeably used, unless specifically stated otherwise. In the context of the present invention, the expressions "is less prone" and "is less affected" are preferably interchangeably used, unless specifically stated otherwise.
In the context of the present invention, said "conditions" are preferably conditions which result in degradation and/or modification of the milk saccharide or mixture of milk saccharides (preferably the active agent) or a fraction thereof upon short and/or prolonged exposure to said conditions. The skilled person will readily understand that the quantity/quality of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) has to be determined using an identical (or at least substantially the same) method and under identical (or at least substantially the same) conditions. Several techniques/methods can be used to assess which saccharide or saccharides are present and in what quantity. Preferred in the context of the present invention is the use of high-performance liquid chromatography (HPLC) or ultra-performance liquid chromatography (UPLC), preferably with refractive index detection, to determine the quantity and/or quality of a saccharide or mixture of at least two different saccharides. As an example, it is referred to the method as described in Christensen et al, 2020, J. Food Sci. 2020, 85(2), p. 332-339 (incorporated by reference) wherein 2'-fucosyllactose and 3- fucosyllactose are quantified. Alternatively, and especially for saccharides at low concentration (below 50 mg/L), it is preferred in the context of the present invention to use high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD). Such a method is described in the Examples section of the present application.
Preferably, said conditions are any one or more of the following: food/feed manufacturing or storage conditions; moisture content (by weight) of at least 15% (w/w), preferably at least 20% (w/w), more preferably at least 25% (w/w), even more preferably at least 30% (w/w), even more preferably at least 35% (w/w), even more preferably at least 40% (w/w), most preferably at least 50% (w/w); feeding conditions, preferably contact with a liquid, wherein said liquid preferably comprises
water, more preferably wherein said liquid is water; gastro-intestinal conditions of an animal, preferably stomach conditions of an animal; presence of a microbial strain which can use said milk saccharide or mixture of at least two milk saccharides, preferably said active agent, as a carbon source; and/or pH which is lower than 5 or higher than 8.

In the context of the invention, the term "food/feed manufacturing or storage conditions" refers to conditions used during the preparation or storage of food and/or feed. Various methods and techniques are known to the skilled person for preparing food and feed as described thoroughly in the book entitled "Food processing technology: principles and practice" (Fellows; second edition; Woodhead Publishing Limited; 2000) which is incorporated by reference. A preferred preparation method comprises any one or more of baking, roasting, frying, heating (dielectric, ohmic or infrared), blanching, pasteurization, heat sterilization, fermentation, irradiation, processing using pulsed electric field, high pressure and extrusion (dry or wet), preferably any one or more of baking, heating (dielectric, ohmic or infrared), heat sterilization, processing using pulsed electric field or high pressure, and extrusion (dry or wet), more preferably any one or more of baking, heating (dielectric, ohmic or infrared), heat sterilization and extrusion (dry or wet), even more preferably selected from the list consisting of baking, heating (dielectric, ohmic or infrared) and extrusion (dry or wet), even more preferably any one or more of baking and extrusion (dry or wet), most preferably comprises extrusion (dry or wet). A preferred preparation method is selected from the list consisting of baking, roasting, frying, heating (dielectric, ohmic or infrared), blanching, pasteurization, heat sterilization, fermentation, irradiation, processing using pulsed electric field, high pressure and extrusion (dry or wet). A more preferred preparation method is selected from a list consisting of baking, heating (dielectric, ohmic or infrared), heat sterilization, processing using pulsed electric field or high pressure, and extrusion (dry or wet). An even more preferred preparation method is selected from the list consisting of baking, heating (dielectric, ohmic or infrared), heat sterilization and extrusion (dry or wet). An even more preferred preparation method is selected from the list consisting of baking, heating (dielectric, ohmic or infrared) and extrusion (dry or wet). An even more preferred preparation method is baking or extrusion (dry or wet). Most preferred preparation method comprises extrusion (dry or wet). The latter is preferably as defined in aspect six of the present invention (it is referred to the section entitled "Method for production of a composition" as described herein). Another most preferred preparation method comprises baking. In this regard, it is preferred that the food/feed that is baked has a moisture content (by weight) of at least 15% (w/w), preferably at least 20% (w/w), more preferably at least 25% (w/w), even more preferably at least 30% (w/w), even more preferably at
least 35% (w/w), most preferably at least 40% (w/w).
It is preferred that a food or feed as disclosed herein has a moisture content (by weight) of at least 15% (w/w), preferably at least 20% (w/w), more preferably at least 25% (w/w), even more preferably at least 30% (w/w), even more preferably at least 35% (w/w), most preferably at least 40% (w/w). Said moisture content is preferably determined by a thermogravimetric analysis (preferably as described herein) or a Karl Fisher titration analysis (preferably as described herein). For example, it is preferred according to the invention that a dough or batter before baking has a moisture content (by weight) of at least 15% (w/w), preferably at least 20% (w/w), more preferably at least 25% (w/w), even more preferably at least 30% (w/w), even more preferably at least 35% (w/w), most preferably at least 40% (w/w). Such a dough or batter, when baked, results in a food/feed having a moisture content of 3-50 % w/w), preferably 5-50% (w/w), more preferably 10-50% (w/w), even more preferably 15-50% (w/w). For example, the moisture content (% w/w) of a cake is 15-30% (w/w)) and of a bread is 35-45% (w/w), while biscuits/cookies typically have a moisture content of 5-10% (w/w), pastries have a moisture content of < 15% (w/w) (Figoni, 2011).
Various methods and techniques are known to the skilled person for storing food and feed as described in said book which is incorporated by reference. Preferred storage methods comprise chilling, atmosphere storage (modified or controlled) and drying (freeze drying, spray drying, granulation, lyophilization, belt drying, drum drying, agitated thin film drying). More preferred storage methods comprise atmosphere storage (modified or controlled) and drying (freeze drying, spray drying, granulation, lyophilization, belt drying, drum drying, agitated thin film drying). Even more preferred storage methods comprise atmosphere storage (modified or controlled), granulation, lyophilization and freeze drying. Reducing and/or preventing contact between the milk saccharide or mixture of milk saccharides (preferably active agent) and a liquid as described further herein, is a preferred example of said storage conditions as described herein.
In the context of the present invention, the term "feeding conditions" refers to conditions to which feed/food is exposed to during the feeding of a human or an animal (preferably as described herein). Preferably said feeding conditions comprise or consist of contact with a liquid, wherein said liquid preferably comprises water, more preferably wherein said liquid is water. Throughout the application and claims, unless specifically stated otherwise, the expression "feeding conditions" is preferably replaced with "contact with a liquid, wherein said liquid preferably comprises water, more preferably wherein said liquid is water". Said liquid may be in direct contact with the encapsulate or might become in contact with the encapsulate after a short period of time, preferably at least 1 min, more preferably at least 5 min, even more preferably at least 10 min, even more preferably at least 30 min, even more preferably at least 1 hour, even more preferably at least 2 hours and/or an exposure time of < 1 day (i.e. 24 hours), preferably < 16 hours, more preferably < 12 hours, even more preferably < 8 hours, even more preferably < 4 hours,
most preferably < 1 hour; or after a prolonged period of time, preferably at least 1 day (i.e. 24 hours), more preferably at least 2 days, even more preferably at least 1 week, even more preferably at least 1 month, even more preferably at least 3 months, even more preferably at least 6 months, most preferably at least 1 year. A particular preferred example in this regard is the incorporation of an encapsulate according to the invention into aquaculture feed (preferably for aquatic animals, more preferably for a water breathing animal, even more preferably for a fish or shrimp). This feed remains in contact with water until consumed by the animal. Contact with the water can take a few minutes for instant feeders (e.g. trout and catfish) or a few hours (e.g. shrimp).
In the context of the invention, "gastro-intestinal conditions of an animal" comprise conditions reflecting those of the stomach (i.e. stomach conditions) and conditions reflecting those of the intestines (i.e. intestinal conditions). Stomach conditions of a monogastric animal typically comprise a pH which is lower than 5.0 (i.e. pH of 1.0 to 5.0) and the presence of enzymes as known to the skilled person. The stomach of a ruminant contains four compartments: rumen (pH 5.5-6.5), reticulum (pH 5.5-6.5), omasum (pH 5.5- 6.5) and abomasum (pH 1-3). Intestinal conditions typically comprise a pH of 6.0 to 8.0, the presence of enzymes and bile salt as known to the skilled person. In the context of the invention, gastro-intestinal conditions of an animal preferably refers to a pH which is lower than 6.0 (i.e. pH of 1.0 to 6.0), preferably lower than 5.0 (i.e. pH of 1.0 to 5.0), and the presence of stomach enzymes as known by the skilled person. In the context of the present invention, "short and/or prolonged exposure to conditions" refers to the duration of exposure to said conditions as described herein. As understood by the skilled person, the duration depends on the intended application (e.g. method for preparing the food/feed or method for storing the food/feed or residence time of aquaculture feed before taken by the animal as described herein). For example, for the manufacture of food/feed using extrusion, the duration of exposure of said conditions is at least the length of the extrusion protocol (kneading, heating, squeezing, cutting) including pre-extrusion (i.e. homogenizing active agent or encapsulate of the invention with the other food/feed ingredients of interest) and post-extrusion (e.g. drying of obtained food/feed in an oven). As to the storage of food/feed, the exposure to said conditions is typically much longer (i.e. at least a day to several days, weeks or months) than is the case for food/feed manufacturing (i.e. half an hour to several hours). "Short exposure to conditions" hence preferably refers to an exposure time of at least 1 min, preferably at least 5 min, more preferably at least 10 min, even more preferably at least 30 min, even more preferably at least 1 hour, even more preferably at least 2 hours and/or an exposure time of < 1 day (i.e. 24 hours), preferably < 16 hours, more preferably < 12 hours, even more preferably < 8 hours, even more preferably < 4 hours, most preferably < 1 hour. "Prolonged exposure to conditions" hence preferably refers to an exposure time of at least 1 day (i.e. 24 hours), preferably at least 2 days, more preferably at least 1 week, even more preferably at least 1 month, even more preferably at least 3 months, even more preferably at least 6 months, most preferably at least 1 year.
In an additional and/or alternative preferred embodiment, an encapsulate according to the invention reduces and/or prevents contact between the milk saccharide or mixture of at least two different milk saccharides (preferably active agent) and a liquid, preferably wherein said liquid comprises water, more preferably wherein said liquid is water. Said liquid may be in direct contact with the encapsulate or might become in contact with the encapsulate after a short period of time, preferably at least 1 min, more preferably at least 5 min, even more preferably at least 10 min, even more preferably at least 30 min, even more preferably at least 1 hour, even more preferably at least 2 hours and/or an exposure time of < 1 day (i.e. 24 hours), preferably < 16 hours, more preferably < 12 hours, even more preferably < 8 hours, even more preferably < 4 hours, most preferably < 1 hour; or after a prolonged period of time, preferably at least 1 day (i.e. 24 hours), more preferably at least 2 days, even more preferably at least 1 week, even more preferably at least 1 month, even more preferably at least 3 months, even more preferably at least 6 months, most preferably at least 1 year.
Hence, reducing and/or preventing contact between the milk saccharide or mixture of milk saccharides (preferably active agent) and a liquid as described herein, is a preferred example of said storage conditions as described herein.
Moreover, an encapsulate according to the invention is particularly useful to be incorporated into feed which is in contact (direct or indirect, preferably direct contact) with an environment having a moisture content (by weight) of at least 15% (w/w), preferably at least 20% (w/w), more preferably at least 25% (w/w), even more preferably at least 30% (w/w), even more preferably at least 35% (w/w), even more preferably at least 40%, even more preferably at least 50% (w/w), most preferably contact with a liquid, wherein said liquid preferably comprises water, more preferably wherein said liquid is water. Particularly preferred is the incorporation of an encapsulate according to the invention into aquaculture feed (preferably for aquatic animals, more preferably for a water breathing animal, even more preferably for a fish or shrimp). This feed remains in contact with water until consumed by the animal. Contact with the water can take a few minutes for instant feeders (e.g. trout and catfish) or a few hours (e.g. shrimp). An aquaculture feed with a high pellet water stability (preferably at least 70 %, more preferably at least 75%, even more preferably at least 80%, even more preferably at least 85%, most preferably at least 90%), i.e. the retention of pellet physical integrity with minimal disintegration and nutrient leaching (e.g. protein, lipid) while in the water until consumed by the animal (Obaldo et al, 2002, Aquaculture Research 33 : p. 369-377), is desired. In this context of the invention, an encapsulate according to the invention incorporated into aquaculture feed significantly reduces and/or prevents leaching of the encapsulated milk saccharide(s) according to the invention into the liquid (preferably comprising water, more preferably said liquid is water) compared to when non-encapsulated saccharide(s) (in an identical or similar amount) are incorporated in the aquaculture feed. In other words, the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as disclosed herein (non-encapsulated, i.e. in the
absence of any carrier material, and preferably provided as powder), is more prone to leaching from the aquaculture feed than the encapsulate according to the invention which comprises an identical milk saccharide or mixture of milk saccharides, preferably an identical active agent. In other words, the quantity and/or quality, preferably the quantity, of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as disclosed herein (non-encapsulated, i.e. in the absence of any carrier material, and preferably provided as powder), is more prone to contact with a liquid (preferably liquid comprising water, more preferably said liquid is water) than the encapsulate according to the invention which comprises an identical milk saccharide or mixture of milk saccharides, preferably which comprises an identical active agent. It is within the context of the invention that the encapsulate of the invention further comprises one or more nutrients of the aquaculture feed in order to reduce and/or prevent leaching of said nutrient(s) from the aquaculture feed into the liquid. Methods to produce aquaculture feed (preferably made by pelleting or extrusion, more preferably by extrusion), to assess water stability of aquaculture feed and to assess the leaching of nutrients (e.g. lipid, protein) are well- known and routinely applied by the skilled person. It is for example referred to Obaldo et al, 2002; Arevalo et al, 2018, Journal of Food, Agriculture & Environment 16(3/4): p. 10-17 and Ighwela et al, 2013, global Veterinaria 2013, 10(6): p. 638-642, all of which are incorporated by reference. Leaching of saccharide(s) from aquaculture feed can be assessed by periodically measuring the amount of each saccharide in the water (wherein the aquaculture feed is put preferably at room temperature, more preferably at 25°C) by using routine available methods such as HPLC, UPLC, mass spectrometry and/or a HPAEC system with pulsed amperometric detection. Preferred analysis methods are described in the Examples of the present application. The amount detected in the water can then be compared with the amount of saccharide(s) originally present in the aquaculture feed.

In an additional and/or alternative even more preferred embodiment of the invention, said food/feed manufacturing or storage conditions comprise direct or indirect contact with a liquid, preferably said liquid comprises water, more preferably said liquid is water.

In a most preferred embodiment of the invention, said food/feed manufacturing or storage conditions comprise, preferably consist of: a temperature of 50°C or higher, preferably 75°C or higher, more preferably 100°C or higher, even more preferably 115°C or higher, even more preferably 125°C or higher, even more preferably 150°C or higher, most preferably 180°C or higher; and a moisture content (by weight) of at least 15% (w/w), preferably at least 20% (w/w), more preferably at least 25% (w/w), even more preferably at least 30% (w/w), even more preferably at least 35% (w/w), most preferably at least 40% (w/w).
One or more of above food/feed manufacturing or storage conditions apply to the preparation or storage methods described herein. For example, extrusion typically occurs at a pressure higher than 1013 mbar, preferably higher than 5 bar, more preferably higher than 10 bar. Further, extrusion typically occurs at a temperature of 50°C or higher, preferably 75°C or higher, more preferably at 100°C or higher, even more

Moreover, dough/batter can comprise a moisture content of at least 15% (w/w), preferably at least 20% (w/w), more preferably at least 25% (w/w), even more preferably at least 30% (w/w), even more preferably at least 35% (w/w), most preferably at least 40% (w/w).
In the context of the present invention, "quantity is less affected" means that in an identical (or at least substantially the same) method it is established that the amount of non-encapsulated (i.e. in the absence of any carrier material, and preferably provided as powder) milk saccharide or non-encapsulated mixture of at least two different milk saccharides (preferably non-encapsulated active agent) upon exposure to identical conditions is lower than the amount of an identical non-encapsulated milk saccharide or nonencapsulated mixture of at least two different milk saccharides (preferably an identical non-encapsulated active agent) when comprised in an encapsulate according to the invention. The skilled person will readily understand that two active agents (or two milk saccharides or two mixtures of milk saccharides) are identical if they consist of the same components and that each component is present in the same quantity in both active agents (or both milk saccharides or both mixtures of milk saccharides). The skilled person will further understand that the exposure time should be identical (or at least substantially the same).
Preferably, the quantity of said milk saccharide or mixture of at least two different milk saccharides (preferably said active agent) when comprised in an encapsulate according to the invention is at least 5.0 %, preferably at least 10.0 %, more preferably at least 15.0 %, higher than the quantity of the nonencapsulated and identical milk saccharide or non-encapsulated and identical mixture of at least two different milk saccharides (preferably non-encapsulated and identical active agent) upon exposure to said conditions.
Preferably, the quantity of said milk saccharide or mixture of at least two different milk saccharides (preferably said active agent) comprised in an encapsulate according to the invention upon exposure to said conditions as described herein is at least 80.0 %, preferably at least 85.0 %, more preferably at least 87.5 %, even more preferably at least 90.0 %, even more preferably at least 92.5 %, most preferably at least 95.0 %, of the quantity of said milk saccharide or mixture of at least two different milk saccharides (preferably said active agent) comprised in the encapsulate before exposure to said conditions. In other words, upon exposure to said conditions as described herein at least 80.0 %, preferably at least 85.0 %, more preferably at least 87.5 %, even more preferably at least 90.0 %, even more preferably at least 92.5
%, most preferably at least 95.0 %, of said milk saccharide or mixture of at least two different milk saccharides (preferably said active agent) is retained in the encapsulate upon exposure to said conditions. For the sake of clarity and as an example, if 20 mg of a saccharide is present in an encapsulate according to the invention, then 20 mg of the same saccharide (i.e. non-encapsulated active agent) is exposed to the same conditions as described herein (e.g. wet extrusion process). The amount of the saccharide is determined in the encapsulated (e.g. 19 mg) and non-encapsulated sample (e.g. 16.5 mg). It can here be concluded that (i) the quantity of the saccharide in the encapsulate is at least 15.0 % higher than in the non-encapsulated sample upon exposure to said conditions and (ii) 95.0 % of the saccharide is retained in the encapsulate upon exposure to said conditions.
In the context of the present invention, "quality is less affected" means that in an identical (or at least substantially the same) method it is established that the extent of degradation and/or modification of non-encapsulated (i.e. in the absence of any carrier material, and preferably provided as powder) nonencapsulated milk saccharide or non-encapsulated mixture of at least two different milk saccharides (preferably non-encapsulated active agent) upon exposure to identical conditions is higher than the extent of degradation and/or modification of an identical non-encapsulated milk saccharide or nonencapsulated mixture of at least two different milk saccharides (preferably an identical non-encapsulated active agent) when comprised in an encapsulate according to the invention. The skilled person will readily understand that two active agents (or two milk saccharides or two mixtures of milk saccharides) are identical if they consist of the same components and that each component is present in the same quantity in both active agents (or both saccharides or both mixtures of saccharides). The skilled person will further understand that the exposure time should be identical (or at least substantially the same).
Preferably, the quantity of said milk saccharide or mixture of at least two different milk saccharides (preferably said active agent) which is degraded and/or modified when comprised in an encapsulate according to the invention is at least 5.0 %, preferably at least 10 %, more preferably at least 15 %, lower than the quantity of the non-encapsulated and identical milk saccharide or non-encapsulated and identical mixture of at least two different milk saccharides (preferably non-encapsulated and identical active agent) which is degraded and/or modified upon exposure to said conditions.
Preferably, the quantity of said milk saccharide or mixture of at least two different milk saccharides (preferably said active agent) which is not degraded and/or not modified when comprised in an encapsulate according to the invention upon exposure to said conditions as described herein is at least 80.0 %, preferably at least 85.0 %, more preferably at least 87.5 %, even more preferably at least 90.0 %, even more preferably at least 92.5 %, most preferably at least 95.0 %, of the quantity of said milk saccharide or mixture of milk saccharides (preferably said active agent) comprised in the encapsulate before exposure to said conditions. In other words, upon exposure to said conditions as described herein at least 80.0 %, preferably at least 85.0 %, more preferably at least 87.5 %, even more preferably at least
90.0 %, even more preferably at least 92.5 %, most preferably at least 95.0 %, of said milk saccharide or mixture of at least two different milk saccharides (preferably said active agent) comprised in the encapsulate is not degraded and/or not modified upon exposure of the encapsulate to said conditions.
In this regard, an encapsulate according to the invention wherein the carrier material comprises a wax (it is referred to the section entitled "Carrier material"), preferably selected from Candelilla wax, Carnauba wax, beeswax, rice bran wax, paraffin wax, jojoba wax, microcrystalline wax and japan wax, more preferably said wax is Candelilla wax, is particularly preferred as the milk saccharide or mixture of at least two different milk saccharides according to the invention (preferably the active agent according to the invention) is less affected (it is referred to the quantity and/or quality of said active agent as described herein) upon short and/or prolonged exposure to conditions (as described herein) compared to the nonencapsulated milk saccharide or non-encapsulated mixture of at least two different milk saccharides (preferably compared to the non-encapsulated active agent).

In the context of the present invention, the feature "atomizing" refers to the disintegration of the liquid melt (i.e. so-called feed liquor) into fine spherical droplets. The feature "solidification" refers to the transformation of the liquid melt into a solid by cooling.
As there is no agglomeration, the size distribution of the droplets determines that of the final particles. The production of liquid drops can be obtained through the use of nozzles. A high pressure nozzle, a fountain nozzle or a vibrating nozzle can be used for example. The formation of droplets of the desired sized can be improved through the use of fractionation means. For example at least one cutting jet, i.e. a continuous jet of liquid or a rotating cutting disc which strikes the feed liquor intermittently to form successive droplets (it is referred to FR2997869 and Lopez-Iglesias et al, 2020, which are incorporated by reference). Another example is to apply an electrostatic potential to a forming droplet in order to reduce its size. Alternatively, spinning discs or spinning perforated baskets are used, wherein the feed liquor is dispersed into liquid droplets by centrifugal force. Said discs and baskets are advantageously used when the feed liquor is more difficult to handle (e.g. higher viscosity), which is for example the case if it is a slurry. It is hence a preferred embodiment of the present invention, to use a prilling device equipped with a rotating cutting disc, a spinning disc or a spinning perforated basket, preferably a spinning disc (also
known as rotating disc). Further, suitable types of equipment for prilling comprise a fluid bed coater equipped for top-spray or tangential-spray (top-spray is preferred) and a turbo jet (Jannin and Cuppok, 2012). For large scale production, a prilling tower is used in the field.
In a preferred embodiment, the temperature of the feed liquor is 7 to 12 degrees (°C), preferably 8 to 10 degrees (°C), more preferably one to five degrees (°C), even more preferably one or two degrees (°C), higher than the solidification point of said feed liquor. In other words, it is preferred that the mixture obtained by dispersing the active agent into the first carrier material has a temperature which is 5-12 °C, preferably 7-12 °C, more preferably 8-10 °C, even more preferably 1-5 °C, even more preferably 1-2 °C, higher than the solidification point / melting temperature of said mixture.
In an additional and/or alternative preferred embodiment, the viscosity of the feed liquor is 20 - 800 millipascal second (mPa.s), preferably 20 - 650 mPa.s, more preferably 20 - 500 mPa.s, even more preferably 20 - 300 mPa.s, most preferably 50 - 200 mPa.s.
In an additional and/or alternative preferred embodiment, the atomizing pressure applied to generate droplets in the prilling process is at least 3 bar, preferably at least 4 bar. Preferably, said atomizing pressure is 4-6 bar.
In an additional and/or alternative preferred embodiment, the contact between the hot melt material (it is referred to the section "carrier material" of the first aspect of the invention) and the active agent (it is referred to the section "active agent" of the first aspect of the invention) is conducted for 1-15 minutes. In an additional and/or alternative preferred embodiment, the feed liquor comprises at least 5% (w/w), preferably at least 10% (w/w), more preferably at least 15% (w/w), even more preferably at least 20% (w/w), even more preferably at least 25% (w/w), most preferably at least 30% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention. In an additional and/or alternative preferred embodiment, the feed liquor comprises < 60% (w/w), preferably < 55% (w/w), more preferably < 50% (w/w), even more preferably < 45% (w/w), most preferably < 40% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention. In an additional and/or alternative preferred embodiment, the feed liquor comprises 5-60% (w/w), preferably 10-50% (w/w), more preferably 15-50% (w/w), even more preferably 20-50% (w/w), even more preferably 25-50% (w/w), even more preferably 25-45% (w/w), even more preferably 25-40% (w/w), most preferably 30-40% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention.
In an additional and/or alternative preferred embodiment, the feed liquor comprises 5-80 % (w/w), preferably 5-75 % (w/w), more preferably 5-70 % (w/w), even more preferably 10-70 % (w/w), even more preferably 20-70 % (w/w), even more preferably 30-70 % (w/w), even more preferably 50-70 % (w/w), most preferably 60-70 % (w/w), carrier material.
Prilling generally results in encapsulates with a median diameter of 50 pm-1000 pm. For most materials
(including hot melt material as described in the section "carrier material' of the first aspect of the invention). Hence, prilling is a preferred encapsulation technique to obtain encapsulates with a median diameter which is longer than 100 pm and/or < 300 pm.
In the field of the present invention, "spray cooling", "spray chilling", "prilling" and "spray congealing" are interchangeable used (Favaro-Trindade et al, 2015, Encapsulation via Spray Chilling/Cooling/Congealing. In: Mishra, M., Ed., Handbook of Encapsulation and Controlled Release, CRC Press, Boca Raton, p. 71-88; Garti and McClements, 2012, chapter 5.1). In the context of the present invention, these terms can be interchangeably used, unless explicitly stated otherwise, and each embodiment disclosed in the context of prilling is considered to be disclosed as well in the context of spray cooling, spray chilling and spray congealing and vice versa. Importantly, spray cooling and spray chilling refer to the same encapsulation principle (i.e. prilling), however, in spray cooling solidification occurs upon contact with ambient air (preferably a temperature of 24-25°C), whereas in spray chilling solidification occurs upon contact with a cooled gas or air (preferably a temperature below 25°C, more preferably a temperature below 24°C). Spray cooling is consequently typically used in conjunction with a feed liquor (i.e. the mixture obtained by dispersing the active agent into the first carrier material according to the invention) which has a melting point lying in the range of 27-42°c, preferably 34-42°C, whereas spray chilling is typically used in conjunction with said feed liquor which has a melting point of > 42°C (and preferably lower than 122°C).
Granulation as disclosed herein is an encapsulation technique which is similar to prilling, with the important difference that not only the feed liquor as disclosed above in the context of prilling is provided, but also a binding agent. The latter allows to bind together small particles as to form granules. Encapsulates obtained by granulation have hence a larger median diameter. Size of the encapsulates is mainly determined by the residence time in the granulator (the longer the layers are allowed to build up, the larger the encapsulates become). Different granulation approaches have been developed which are suitable for encapsulating an active agent according to the invention. Preferably, said granulation is selected from the list consisting of high shear wet granulation, high shear melt granulation, fluid bed wet granulation, continuous wet granulation and continuous melt granulation, more preferably selected from the list consisting of fluid bed wet granulation, continuous wet granulation and continuous melt granulation, most preferably fluid bed wet granulation and continuous wet granulation.
Each embodiment disclosed in the context of prilling is also disclosed in the context of granulation. In a preferred embodiment, said binding agent is selected from the list consisting of starch, liquid glucose, povidone, cellulose, methyl cellulose, ethyl cellulose, polyvinyl pyrrolidone, gelatin, polyethylene glycol, sucrose, acacia, tragacanth and a gum. Preferably, a gum as disclosed in the present application.
Granulation generally results in encapsulates with a median diameter of at least 50 pm to hundreds of micrometer and is particularly preferred if larger encapsulates are required than for example can be
obtained with prilling.
Spray drying as disclosed herein (Garti and McClements, 2012, chapter 4; Pinon-Balderrama et al, 2020, Processes 8(889); all incorporated by reference) is an encapsulation technique which is similar to prilling, i.e. spherical particles are produced from molten carrier material, strong solutions or slurries, i.e. so-called feed liquor (i.e. mixture comprising active agent dispersed/dissolved into a first carrier material in the context of the present invention). In this context, a hot melt material and/or a polymer, preferably a hot melt material, as described in section "carrier material" of the first aspect of the invention is particularly suitable for spray drying (i.e. for spray drying, the carrier material preferably comprises a hot melt material and/or polymer, more preferably a hot melt material). In contrast to prilling, liquid drops that are generated (i.e. atomizing) are subsequently solidified individually by rapid evaporation of the solvent in which the carrier material is dissolved. Usually air, preferably heated (i.e. temperature higher than ambient temperature as defined earlier herein), supplies the latent heat of vaporization required to remove the solvent from the coating material to form the encapsulates. Contact between the spray droplets and the air can be done in three ways: (i) co-current drying (air and particles move in same direction through drying chamber), counter-current drying (air and particles move in opposite directions through drying chamber) and (iii) mixed-flow (both co-current and counter-current phases are present) (Farheen et al, 2017). In the context of the present invention, co-current drying is preferred. A spray dryer includes an atomizer (preferably a nozzle or spinning wheel), a drying chamber supplied with air (preferably heated air), air heater, blower or fan (movement of air), product collector and a cyclone or bag-filter (separation of dried particles from humid air). As understood by the skilled person, encapsulation by spray drying comprises the following steps: (i) preparation of a feed liquor by dispersing/dissolving the active agent (as described in the first aspect of the invention) into a first carrier material as described herein, preferably a hot melt material and/or a polymer, preferably a hot melt material, as described in section "carrier material" of the first aspect of the invention; (ii) atomizing the feed liquor as to form droplets; (iii) drying the droplets, preferably by an air stream, more preferably by a heated air stream (i.e. temperature higher than ambient temperature as defined earlier herein) as to form solidified encapsulates. In the context of the present invention, the feature "atomizing" refers to the disintegration of the liquid melt (i.e. so-called feed liquor) into fine spherical droplets. The feature "solidification" refers to the transformation of the liquid melt into a solid by cooling.
In a preferred embodiment, the inlet temperature, i.e. the temperature of the drying medium (gas stream), is 140-220°C, preferably 150-200°C, more preferably 160-200°C, most preferably 160-190°C.
In an additional and/or alternative preferred embodiment, the feed flow rate is chosen such that the median diameter of the produced encapsulates is as described in the section "Encapsulate" of the first aspect of the invention. A higher feed flow rate generally results in a larger median diameter of the obtained encapsulates. Preferably, the feed flow rate is 0.5-100 mL/min, more preferably 0.5-50 mL/min,
even more preferably 0.5-25 mL/min, even more preferably 0.5-15 mL/min, most preferably 1.0-10.0 mL/min.
In an additional and/or alternative preferred embodiment, the residence time, i.e. time elapsed from the entrance of the atomized liquid into the drying chamber until it leaves the dryer in the form of encapsulates, is preferably 2-35 seconds, more preferably 5-25 seconds, even more preferably 5-15 seconds, most preferably 10-15 seconds.
In an additional and/or alternative preferred embodiment, the viscosity of the feed liquor is 20 - 800 millipascal second (mPa.s), preferably 20 - 650 mPa.s, more preferably 20 - 500 mPa.s, even more preferably 20 - 300 mPa.s, most preferably 50 - 200 mPa.s.
In an additional and/or alternative preferred embodiment, the feed liquor constitutes at least 5% (w/w), preferably at least 10% (w/w), more preferably at least 15% (w/w), even more preferably at least 20% (w/w), even more preferably at least 25% (w/w), most preferably at least 30% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention. In an additional and/or alternative preferred embodiment, the feed liquor constitutes < 60% (w/w), preferably < 55% (w/w), more preferably < 50% (w/w), even more preferably < 45% (w/w), most preferably < 40% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention. In an additional and/or alternative preferred embodiment, the feed liquor constitutes 5-60% (w/w), preferably 10-50% (w/w), more preferably 15-50% (w/w), even more preferably 20-50% (w/w), even more preferably 25-50% (w/w), even more preferably 25-45% (w/w), even more preferably 25-40% (w/w), most preferably 30-40% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention.
In an additional and/or alternative preferred embodiment, the feed liquor comprises 5-80 % (w/w), preferably 5-75 % (w/w), more preferably 5-70 % (w/w), even more preferably 10-70 % (w/w), even more preferably 20-70 % (w/w), even more preferably 30-70 % (w/w), even more preferably 50-70 % (w/w), most preferably 60-70 % (w/w), carrier material.
Spray drying generally results in encapsulates with a median diameter of 1 pm-100 pm. Hence, spray drying is a preferred encapsulation technique to obtain encapsulates with a median diameter which is not longer than 100 pm.
Freeze drying as disclosed herein, also known as lyophilization and cryodesiccation, refers to an encapsulation technique wherein particles are produced (Garti and McClements, 2012, chapter 4; incorporated by reference) based on the principle of dehydration with sublimation, i.e. frozen unbound liquid (usually water) sublimates from solid state into gas state when adequate amount of heat is applied under very low environment pressure by a high vacuum condition. As understood by the skilled person, encapsulation by freeze drying is a multi-stage process comprising the following steps: (i) preparation of
a mixture by dispersing/dissolving the active agent (as described in the first aspect of the invention) and a first carrier material as described herein, preferably a polymer, more preferably selected from a polysaccharide, a resin, a cellulose, a cellulose-derivative and a protein, as described in section "carrier material" of the first aspect of the invention, in a liquid, preferably water; (ii) cooling said mixture so that said liquid crystallizes, in other words freezing said mixture, preferably at a temperate of < -20°C, more preferably < -30°C, even more preferably < -40°C, even more preferably at a temperature of -20°C to - 80°C, even more preferably -20°C to -60°C, most preferably -30°C to -60°C; (iii) drying said mixture under low environmental pressure, preferably said pressure is constant, as to remove frozen free moisture (known as primary drying step); and (iv) further drying said mixture at a temperature which is higher than in step, whereas pressure is preferably kept constant (iii), this step is known as secondary drying step, as to form encapsulates. A freeze dryer typically comprises a product chamber (e.g. for vials or for trays), a condenser (attracting the vapors being sublimed off the frozen mixture) and a vacuum pomp.
In a preferred embodiment, the temperature during the primary drying step is below the collapse temperature of the frozen mixture. The collapse temperature can be routinely determined by the skilled person, crystalline products have a well-defined freezing/melting point (i.e. collapse temperature) whereas the collapse temperature of amorphous products is typically a few degrees warmer than the glass transition temperature of said amorphous products. Preferably, the temperature during the primary drying step (i.e. the applied temperature) is 3-10°C, preferably 5-10°C, more preferably 5-7°C, lower than the collapse temperature of the frozen mixture. In an additional and/or alternative preferred embodiment, the temperature during the primary drying step is -40°C to 20°C, preferably -40°C to 0°C, more preferably -40°C to -10°C, even more preferably -40°C to -20°C.
In an additional and/or alternative preferred embodiment, the pressure during the primary drying step is constant. In an additional and/or alternative preferred embodiment, the pressure during the primary drying step is < 1 mbar, preferably < 0.5 mbar, more preferably < 0.2 mbar. Preferably, the pressure during the primary drying step is 0.1-0.5 mbar, more preferably 0.1-0.25 mbar, most preferably 0.1-0.2 mbar.
In an additional and/or alternative preferred embodiment, the primary drying step is conducted until at least one of the following occurs: temperature of the mixture is similar or equal to the applied temperature; condenser temperature has returned to its original temperature (i.e. condenser does not trap high loads of vapor); pressure in the system has returned to its original low value.
In an additional and/or alternative preferred embodiment, the temperature during the secondary drying step is higher than the temperature during the primary drying step, preferably the temperature is higher than the ambient temperature, more preferably the temperature is at least 20°C, even more preferably the temperature is 25°C-50°C, most preferably 25°C-40°C.
In an additional and/or alternative preferred embodiment, the pressure during the secondary drying step
is constant. In an additional and/or alternative preferred embodiment, the pressure during the secondary drying step is lower than the pressure during the primary drying step. Preferably, the pressure during the secondary drying step is < 1 mbar, preferably < 0.5 mbar, more preferably < 0.2 mbar, even more preferably < 0.1 mbar.
In an additional and/or alternative preferred embodiment, the mixture constitutes at least 5% (w/w), preferably at least 10% (w/w), more preferably at least 15% (w/w), even more preferably at least 20% (w/w), even more preferably at least 25% (w/w), most preferably at least 30% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention. In an additional and/or alternative preferred embodiment, the mixture constitutes < 60% (w/w), preferably < 55% (w/w), more preferably < 50% (w/w), even more preferably < 45% (w/w), most preferably < 40% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention. In an additional and/or alternative preferred embodiment, the mixture constitutes 5-60% (w/w), preferably 10-50% (w/w), more preferably 15-50% (w/w), even more preferably 20-50% (w/w), even more preferably 25- 50% (w/w), even more preferably 25-45% (w/w), even more preferably 25-40% (w/w), most preferably 30-40% (w/w), of the milk saccharide or mixture of at least two different milk saccharides (preferably the active agent) as described in the first aspect of the invention.
In an additional and/or alternative preferred embodiment, the mixture (before freezing) constitutes 5-80 % (w/w), preferably 5-75 % (w/w), more preferably 5-70 % (w/w), carrier material.
Freeze drying generally results in encapsulates with a median diameter of 1 pm-100 pm. Hence, freeze drying is a preferred encapsulation technique to obtain encapsulates with a median diameter which is not longer than 100 pm.
Fluidized air bed coating (FAB; also referred to as spray coating and air suspension coating ; sometimes also referred to as Wuster coating as Wuster invented the first version of FAB, however this is a specific version of FAB and since then several modified versions have been developed, all of which are fluidized air bed coating in the context of the present invention) as disclosed herein refers to an encapsulation technique wherein a carrier material is applied onto particles (i.e. spraying in the context of the present invention) in a batch process or a continuous set-up (Garti and McClements, 2012, chapter 7; Subasi et al, 2021, Plant Antioxidants and Health, p. 1 to 37, section 3.1; Ronsse, 2006; "Modelling heat and mass transfer in fluidized bed coating processes, Ph.D. thesis, Ghent University, ISBN 90-5989-120-1; all incorporated by reference). Herein, encapsulates (preferably of the matrix-type; preferably obtained by an encapsulation method as described herein) are suspended by a gas stream (preferably an air stream) and sprayed with an atomized carrier material. In this context, a hot melt material and/or a polymer, preferably a polymer, as described in section "carrier material" of the first aspect of the invention, is particularly suitable for fluidized air bed coating (i.e. for FAB, the carrier material preferably comprises a
hot melt material and/or polymer, more preferably a polymer). Fluidization arises when an upward moving gas (preferably air) drawn to a bed of encapsulates reaches a sufficient velocity to suspend said encapsulates. This fluidizing gas/air can also provide the evaporative capacity to dry the coating material on the particles.
The carrier material (i.e. coating) is applied through a spray, i.e. liquid drops are generated (e.g. atomization through the use of a nozzle) and depending on the spray direction from the nozzle, said spray can be a top spray, a bottom spray or a tangential spray (Ronsse, 2006, sections 1.3.3.1 to 1.3.3.3). In the context of the present invention, the carrier material (i.e. coating) is preferably applied (i.e. sprayed) at the bottom (e.g. bottom spray) or through a tangential spray, more preferably through a bottom spray, both have the advantage of reducing the distance between the particles and the drops of coating solution, thereby reducing the risk of premature drying of the coating. Moreover, a more uniform coating is obtained. As understood by the skilled person, encapsulation by FAB comprises the following steps: (i) providing encapsulates, preferably as described according to the first aspect or obtained by a method according to the second aspect, more preferably encapsulates of the matrix type, as a fluidized bed; (ii) providing a carrier material (i.e. a coating), preferably a hot melt material and/or a polymer, more preferably a polymer, as described in the first aspect of the invention; and (iii) atomizing said carrier material, preferably through the use of a nozzle, as to form a spray of droplets that coat said encapsulates (i.e. resulting in coated encapsulates).
A fluidized bed instrument generally comprises a product container, an expansion chamber, an gas/air handling system and an exhaust system (for retention of particles within the processing chamber) (Garti and McClements, 2012, chapter 7.3.3).

In an additional and/or alternative preferred embodiment, the spraying rate is 0.01 - 1.0 g/s, preferably
0.01 - 0.5 g/s, more preferably 0.05 - 0.5 g/s, most preferably 0.05 - 0.25 g/s.
In an additional and/or alternative preferred embodiment, the storage vessel (from which the molten carrier material is pumped), the nozzle and atomizing air are heated in order to prevent solidification of the carrier material (i.e. coating).
In an additional and/or alternative preferred embodiment, the viscosity of the coating (i.e. carrier material as disclosed herein) is 20 - 800 millipascal second (mPa.s), preferably 20 - 650 mPa.s, more preferably 20 - 500 mPa.s, even more preferably 20 - 300 mPa.s; most preferably 50 - 200 mPa.s.
In an additional and/or alternative preferred embodiment, the temperature of the coating (i.e. carrier material as disclosed herein) is 1-25°C, preferably l-20°C, more preferably 5-20°C, more preferably 5- 15°C, most preferably 5-10°C, higher than the solidification point / melting temperature of said coating.

After extrusion, materials pressure will decrease sharply and moisture will evaporate so as to achieve the goal of extrusion. Moisture content (preferably water content) during dry extrusion is < 20 %. The principle of wet extrusion is similar to that of dry extrusion, but requires the addition of water and vapor to obtain a moisture content (preferably water content) of > 20 %, preferably > 25 %, and sometimes even > 30 %, as the rising of materials temperature depends on the addition of vapor.

The skilled person is familiar with choosing the appropriate baking temperature and time depending on the intended nutritional composition. Depending on the properties of the nutritional composition, thickness of said composition and desired doneness, the skilled person will be able to routinely determine the appropriate temperature and duration of the baking process. Further, it is a well-known principle that one can achieve similar results by either baking for a short time at a higher temperature or baking for a longer time at a lower temperature. Preferably, said nutritional composition is baked until the desired doneness has been reached, more preferably heated until said nutritional composition is cooked.
Preferably, throughout the application and claims, said baking is for at least 2 minutes, preferably at least 3 minutes, more preferably at least 5 minutes, even more preferably at least 7 minutes, most preferably at least 10 minutes.

Examples
The invention will be described in more detail in the examples. The following examples will serve as further illustration and clarification of the present invention and are not intended to be limiting in any way.
Example 1: Materials and Methods (oligosaccharides)
3'SL and 6'SL
3'sialyllactose (3'SL) and 6'sialyllactose (6'SL) were recombinantly produced in E. coli and purified as described in WO 2022/034079 (Examples 11, 13 and 14; the E. coli strains are described in Example 3 of WO 2018/122225 for 6'SL and Example 7 of WO 2018/122225 for 3'SL wherein an alpha-2, 3- sialyltransferase from Pasteurella multocida, i.e. amino acids 1-268 of Uniprot ID Q9CLP3 sequence vl, was used) and subsequently spray dried as described in Example 21 of WO 2022/034079 to obtain 3'SL powder (purity 98.4 %) and 6'SL powder (purity 98.6 %).
Analytical analysis
Standards such as but not limited to sucrose, lactose, N-acetyllactosamine (LacNAc, Gal-bl,4-GlcNAc), lacto-N-biose (LNB, Gal-bl,3-GlcNAc), fucosylated LacNAc (2'FLacNAc, 3-FLacNAc), sialylated LacNAc, (3'SLacNAc, 6'SLacNAc), fucosylated LNB (2'FLNB, 4'FLNB), lacto-/V-triose II (LN3), lacto-/V-tetraose (LNT), lacto-/V-neo-tetraose (LNnT), LNFP-I, LNFP-II, LNFP-III, LNFP-V, LNFP-VI, LSTa, LSTc and LSTd were purchased from Carbosynth (UK), Elicityl (France) and IsoSep (Sweden). Other compounds were analyzed with in-house made standards (e.g. 3'SL and 6'SL).
The oligosaccharide composition in pre-extrusion and post-extrusion samples were determined by mixing 4 g of said sample into 20 ml of citrate buffer (0.02M, pH 5.0). An internal standard (galactoronic acid) was added until a final concentration of 3 mg/ml. The mixture was incubated at 70°C for 10 min before it was blended at 20000 rpm for 5 min using an ultra turrax (IKA T 18), followed by shaking a 37°C for 30 min. Protein precipitation was performed using MeOH at the ratio of 2:1 volume of MeOH : sample. The mixture was kept at -20°C for lh, followed by centrifugation at 14000 rpm for 5 min. The supernatant was filtrated using PTFE filter 0.2 pm. 3'SL and 6'SL in the flowthrough was quantified using HPAEC-PAD on a Dionex ICS5000+ system (Thermo Fisher). A volume of 5 pL of sample was injected on a Dionex CarboPac PA200 column 4 x 250 mm with a Dionex CarboPac PA200 guard column 4 x 50 mm. The column temperature was set to 30 °C. A gradient was used wherein eluent A was deionized water, wherein eluent B was 200 mM Sodium hydroxide and wherein eluent C was 500 mM Sodium acetate. The oligosaccharides were separated in 60 min while maintaining a constant ratio of 25 % of eluent B using the following gradient: an initial isocratic step maintained for 10 min of 75 % of eluent A, an initial increase from 0 to 4 % of eluent C over 8 min, a second isocratic step maintained for 6 min of 71 % of eluent A and 4 % of eluent C, a second increase from
4 to 12 % of eluent C over 2.6 min, a third isocratic step maintained for 3.4 min of 63 % of eluent A and 12 % of eluent C and a third increase from 12 to 48 % of eluent C over 5 min. As a washing step 48 % of eluent C was used for 3 min. For column equilibration, the initial condition of 75 % of eluent A and 0 % of eluent C was restored in 1 min and maintained for 11 min. The applied flow was 0.5 mL/min. The actual concentration of 3'SL and 6'SL in the pre-extrusion and post-extrusion samples (mg oligosaccharide per g dried matter) were computed based on their concentrations measured by the Dionex system and the dried matter of dog food after subtracting the water content.
Oligosaccharide composition of an encapsulate
The composition of 3'SL and 6'SL in microcapsules were determined as follows. First, 20 ml of citrate buffer (0.02M, pH 5.0) was added into 50 mg of oligosaccharide microcapsules. Internal standard (galactoronic acid) was added until a final concentration of 3 mg/ml. The mixture was incubated at 70°C for 10 min before it was blended at 20000 rpm for 5 min using an ultra turrax (IKAT 18), followed by shaking a 37°C for 30 min. Protein precipitation was performed using MeOH at the ratio of 2:1 volume of MeOH : sample. The mixture was kept at -20°C for lh, followed by centrifugation at 14000 rpm for 5 min. The supernatant was filtrated using PTFE filter 0.2 pm. 3'SL and 6'SL in the flowthrough was quantified using HPAEC-PAD on a Dionex ICS5000+ system (Thermo Fisher) according to Example 1.
Example 2: Encapsulation
A mixture of the 3'sialyllactose (3'SL) powder and the 6'sialyllactose (6'SL) powder was made in a ratio of 9 (3'SL):1 (6'SL). The obtained mixture was prilled at a concentration of 35% (w/w) in (1) hydrogenated palm oil (GV60, Archer Daniels Midland (ADM)) or (2) Candelilla wax (Interchimie). Microparticles were formed upon contacting ambient air (microparticles "A" = hydrogenated palm oil; microparticles "B" = Candelilla wax). Characteristics of the obtained microparticles are provided in Table 3.
A fluidized bed coater (e.g. Glatt; Wurster geometry, i.e. bottom spray) was used to apply a coating to microparticles "A" and "B" as to obtain microparticles of the core-shell type. A high velocity air stream is applied through a cylinder that is centrally placed just above the air inlet at the narrow bottom of a conus shaped chamber. Microparticles "A" or "B" were introduced into the chamber of the coating apparatus as to form a fluidized bed. The coating material was molten and fed through heated tubes towards the nozzle, wherein the coating material was selected from:
Hydrogenated palm oil (GV60, Archer Daniels Midland (ADM),
Candelilla wax (Interchimie),
Shellac gum (Aquagold; Stroever Shellack Bremen) mixed with starch (Amioca powder TF; Ingredion) at the ratio 95:5 (w/w), respectively.
The coating was applied onto the microparticles "A" or "B" by spraying it from the nozzle onto the fluidized microparticles within the cylinder. During the coating process, microparticles left the top of the cylinder and descended back into the fluidized bed. Cool air congealed the coating during the descent. The coating applied during the FAB step represented up to 40% weight of the finally obtained coated microparticles. The coated microparticles each consisted of approximately 25% (w/w) oligosaccharides (i.e. said mixture of 3'SL and 6'SL) as outlined in Table 2. Hence, the microparticles were obtained as follows:
Microparticles "C": microparticles A + hydrogenated palm oil coating
Microparticles "D": microparticles A + Candelilla wax coating
Microparticles "E": microparticles A + Shellac gum with starch coating
Microparticles "F": microparticles B + hydrogenated palm oil coating Microparticles "G": microparticles B + Candelilla wax coating Microparticles "H": microparticles B + Shellac gum with starch coating
Microscopic analysis (optical microscope at lOOx magnification; stereomicroscope at 50x magnification) showed that the microparticles "A" to "H" are beige to slightly marron, rather spherical and rather homogeneous. The coating membrane of microparticles "C" to "H" is thin but completely surrounds the prills.
The water activity, % dry extract (i.e. (mass of the sample after 24h at 105°C / initial mass of the sample) x 100), particle size distribution parameters and flowability properties were determined for (i) microparticles "A" to "H" and (ii) the mixture of dried 3'SL powder and dried 6'SL powder (referred to as "oligosaccharide mixture", i.e. not encapsulated). An overview of the results can be found in Table 3:
Table 3 - Overview microparticles
As shown in Table 3, all microparticles "A" to "H" have a water activity (Aw) which is higher than that of the non-encapsulated active agent (mixture of dried 3'SL and dried 6'SL = "oligosaccharide mixture"). Further, the flowability of the microparticles is improved from poor to good or even excellent compared to the oligosaccharide mixture. In particular, microcapsules "B", "D" and "G", wherein the complete particle is made of Candelilla wax (microcapsule "B") or wherein the shell is made of Candelilla wax (microcapsules "D" and "G") are characterized by an excellent flowability.
In addition, it was noted that each microparticle contain a high dry extract (> 96.6 % and exceeding that of the oligosaccharide mixture) and show a particle size distribution which is homogeneous with a span score around 1.
Water activity (Aw)
Water activity (Aw) values were obtained with a LabSwift-aw (Novasina) at ambient temperature between 24.4-24.9 °C. The values were recorded after a stabilization period (time varying according to the sample tested).
Dry extract determination
Dry extracts were obtained by a thermogravimetric analysis. Samples of each powder were incubated in a stove at 105°C for 24h. The measures were performed in triplicate for each sample. The dry extract proportion contained in the sample was obtained using the following equation : % dry extract = (mass of the sample after 24h at 105°C / initial mass of the sample) x 100.
Particle size distribution
Particle size distribution was obtained by the laser diffraction technique using a MasterSizer S apparatus
(Malvern Instruments Ltd), 5000 counts.
Flowability
Carr index lc (Compressivity index) and Hausner ratio Rh were determined by measuring the bulk density (pb) and the tapped density (pt) of the powders, pb and pt were obtained with a 100 ml measuring cylinder, pb is the initial density and pt is obtained after tapping the measuring cylinder on a flat surface, 1 tap / s, 180 taps. Below are equations to calculate lc and Rh: lc = 100 x (pt - pb) / pt Rh = pt / Pb
The flow character was then scored as depicted in Table 1.
Example 3: Materials and Methods (production of dog food kibbles)
Extrusion procedure
Microparticles "D", "E" or "H" as prepared in Example 2 was mixed into 5 kg dog food (major components shown in Table 4) at the inclusion ratio of 48 g microcapsules per kg dog food. A control batch was prepared by mixing dog food with the same amount of the non-encapsulated oligosaccharide mixture (3'SL+6'SL). Before subjecting each dog food batch to the extrusion process, each batch was homogenized for 15 min.
A portion of 100 g of each prepared batch was preserved at -80°C for analytics ("pre-extrusion sample").
Each batch of the homogenized dog food (5kg) was processed using the extruder type BC 45 (Clextral).
Extruder parameters are summarized in table 5. The kibbles at the outcome of the dies were dried in the oven for 50 min at 60°C. A portion of 100 g was preserved at -80°C for analytics ("post-extrusion sample").
Water content
Water content of pre-extrusion and post-extrusion samples were determined using the Karl-Fisher method (Laboratorium ECCA N.V., Belgium).
Example 4: Production of dog food kibbles
Dog food kibbles containing an equal amount of microparticles "D", "E" or "H" were prepared according to the extrusion procedure described in Example 3. As a control, dog food kibbles containing spray-dried 3'SL and spray-dried 6'SL (in an amount which is similar to the microparticle containing kibbles) were prepared using the same extrusion procedure ("non-encapsulated oligosaccharide mixture"). The concentration of 3'SL and 6'SL were determined for each dog food batch before extrusion ("preextrusion") and after extrusion ("post-extrusion") and expressed as mg/g dried matter (it is referred to Example 1) as shown in Table 6.
Table 6 - Oligosaccharide concentration in pre- and post-extruded dog food kibbles (mg/g dried matter)
As shown in Table 6, the retention of 3'SL and 6'SL within the dog food upon exposure to the extrusion process is greatly improved when the oligosaccharides are encapsulated compared to the control. These data hence demonstrate that encapsulating oligosaccharides according to the invention provides a good to excellent protection against degradation during dog food extrusion (hallmarked by conditions such as a high temperature, high pressure and high moisture content during wet extrusion). Example 5: Materials and Methods (production of dog food kibbles at very high temperature)
Extrusion procedure
Microparticles "E" as prepared in Example 2 was mixed into 5 kg dog food (major components shown in Table 4) at the inclusion ratio of 48 g microcapsules per kg dog food. A control batch was prepared by mixing dog food with the same amount of the non-encapsulated oligosaccharide mixture (3'SL+6'SL). Before subjecting each dog food batch to the extrusion process, each batch was homogenized for 15 min. A portion of 100 g of each prepared batch was preserved at -80°C for analytics ("pre-extrusion sample").
Each batch of the homogenized dog food (5kg) was processed using the extruder type BC 45 (Clextral). Extruder parameters are summarized in Table 7 (which are different from those summarized in Table 5 of Example 3). The kibbles at the outcome of the dies were dried in the oven for 50 min at 60°C. A portion of
100 g was preserved at -80°C for analytics ("post-extrusion sample").
Water content
Water content of pre-extrusion and post-extrusion samples were determined using the Karl-Fisher method (Laboratorium ECCA N.V., Belgium).
Example 6: Production of dog food kibbles at very high temperature
Dog food kibbles containing microparticles "E" were prepared according to the extrusion procedure described in Example 5. As a control, dog food kibbles containing spray-dried 3'SL and spray-dried 6'SL (in an amount which is similar to the microparticle containing kibbles) were prepared using the same extrusion procedure ("non-encapsulated oligosaccharide mixture"). The concentration of 3'SL and 6'SL were determined for each dog food batch before extrusion ("pre-extrusion") and after extrusion ("postextrusion") and expressed as mg/g dried matter (it is referred to Example 1) as shown in Table 8.
Table 8 - Oligosaccharide concentration in pre- and post-extruded dog food kibbles (mg/g dried matter)
As shown in Table 8, the retention of 3'SL and 6'SL within the dog food upon exposure to the extrusion process is greatly improved when the oligosaccharides are encapsulated compared to the control, even under the extremely high temperatures used during the extrusion process (see Table 7). These data hence demonstrate that encapsulating oligosaccharides according to the invention provides an excellent protection against degradation during dog food extrusion even at very high temperatures (further hallmarked by conditions such as a high pressure and high moisture content during wet extrusion).
