Definitions
- the technology disclosed in this specification pertains to a method of adsorbing an active ingredient onto free-flowing porous starch granules, to provide free-flowing porous starch granules with the active ingredient adsorbed or plated onto them.
- the method relates to introducing the active ingredient in an oil-and-liquid emulsion to facilitate its adsorption to the porous starch granules.
- the adsorbed free- flowing porous starch granules are useful for storing and delivering oil-based ingredients for use in a variety of edible, industrial, and pharmaceutical compositions.
- compositions have a dry. solid form and are made of dry ingredients, where the addition of a liquid ingredient will destroy the dry, solid form of the composition.
- One strategy for introducing liquid components to such a dry, solid mixture is to plate the liquid onto free-flowing porous starch granules - the granules adsorb the liquid, but retain a dry, solid, and free-flowing form - thus allowing the incorporation of the liquid without losing the dry, solid form of the composition.
- an active ingredient such as a flavorant, nutrient, or fragrance
- an emulsifying compound in an emulsifying compound
- the active ingredient is stored or delivered as a free-flowing powder, which provides reductions in manufacturing, storing, and delivery costs, and protects or extends the performance and shelf-life stability of the active ingredient.
- a free-flowing powder which provides reductions in manufacturing, storing, and delivery costs, and protects or extends the performance and shelf-life stability of the active ingredient.
- This specification describes a method of transferring active ingredients onto porous starch granules, by including the active ingredient as part of an oil-and-liquid emulsion for delivery to the porous starch granules, and for protecting the activity of the active ingredients over time. Some methods are performed in the absence of heat, to prevent exposure to an environmental condition that damages or impairs the stability and activity of some active ingredients.
- This specification also describes free- flowing porous starch granules loaded with active ingredients whose functionality is protected over time, and to uses of the adsorbed porous starch granules in a variety of compositions. This specification also discloses compositions comprising the adsorbed porous starch granules.
- Such adsorbed porous starch granules can be used to convert liquid emulsions into easy-to-handle, free flowable powders without the need of spraydrying or freeze-drying steps or equipment, or application of other drying technology, which can reduce the capital expense, maintenance, and energy costs associated with equipment.
- Such granules also convert liquid compositions into a dry powder form that is easily stored and transported. By plating active ingredients in the presence of an emulsifying agent, amount of active ingredient delivered in increased and the shelf life, stability, and chemical or biological activities of the active ingredients are protected or extended.
- Figure 1 reports measurements of the mean particle sizes of emulsion compositions made according to the specification.
- Figure 2 shows images of starch granules plated with the oil-and-water emulsion composition of Figure 1.
- Figure 3 reports measurements of the mean particle sizes of porous starch granules, and of porous starch granules plated with an oil-and-water emulsion, made according to the specification.
- Figure 4 reports measurements of the mean particle sizes of an emulsion composition made with a starch blend according to the specification.
- Figure 5 shows images of starch particles coated with an emulsion composition.
- Figure 6 reports measurements of the mean particle sizes of an emulsion composition made with a starch blend according to the specification.
- Figure 7 shows images of starch granules coated with an emulsion composition.
- Figure 8 reports measurements of the mean particle sizes of porous starch granules, and of porous starch granules plated with an oil-and-water emulsion, made according to the specification.
- Figure 9 reports measurements of the amount of oil recovered from different starch granules upon which oil compositions had been loaded, using a variety of methods. The experiments were performed using oil compositions that were prepared fresh or aged prior to use.
- Figure 10 reports measurements of sensory evaluations of the oil-loaded starch granule compositions of Figure 9.
- a sensory panel assessed each sample for the intensity of its overall citrus aroma and the intensity of its oxidized aroma.
- polysaccharide refers to starches, gums, dextrins, celluloses, and heteropolysaccharides, and derivatives thereof, hydrolysates thereof, crosslinked products thereof and combinations thereof. Where one polysaccharide is used as a material, another polysaccharide may substitute for it in other embodiments.
- porous starch granule used interchangeably with “porous starch particle”, refers to a starch product that has multiple pores or concave portions or depressions on its exterior surface, that increase the surface area when compared to a smooth starch granule of similar size and overall dimension, as show n by scanning electron microscopic techniques. Some indentations are present as dimples or dents on the surface of the granule, which form concave portions at a single location on the granule. Some indentations are present as passageways that traverse the interior of the granule, and connect openings at least two locations on the granule. The pores and passageways are present in a range of sizes and dimensions, to provide a starch granule with an uneven exterior surface.
- a porous starch granule is a particulate substance with porous adsorption properties. Porous starch granules absorb wet/liquid substances maintaining their dry substance. Native starch is made of amylopectin and amylose, which together form a densely packed crystalline structure known as a granule. Porous starch particles or granules differ from native starch granules in that chemical or physical treatments of the native starch causes the formation of an increased volume of pores on its surface, giving it a sponge-like structure that creates adsorbancy where typical native nongelatinized starches have little to none.
- Porous starch granules are generated, for example, when granular starch is modified by enzymatic degradation and/or crosslinking processes. Porous starch granules are also generated by other processes, such processes providing a large specific surface area to the modified starch granules.
- a starch product may contain porous starch granules, non-porous starch granules, or a mixture thereof.
- free-flowing starch or other materials refers to dry or solid materials that are amenable to pouring. Free-flowing starches may exhibit an ease of flow that is comparable to a liquid, to move with a liquid-like motion, not to gather in clumped masses.
- aqueous component refers to a component comprising water regardless of its phase (solid, liquid, gaseous, etc.).
- Aqueous components may comprise other ingredients which are suspended, dispersed, dissolved, or otherwise mixed in the aqueous component.
- Aqueous components have various pHs.
- emulsion composition refers to a mixture containing at least oil, another liquid, and an emulsifying agent.
- An “emulsifying agent” is a substance that facilitates the mixture of two or more liquids that are normally immiscible with each other (e.g., oil and water).
- one or more components of the emulsion composition comprise an active ingredient; in some applications, an emulsion composition contains an additional ingredient that contains an active ingredient.
- active ingredient refers to a composition that possesses a physical, chemical, or biological activity.
- An active ingredient is a composition whose delivery is desired for its ability to cause or enhance any desired effect upon or after delivery as part of another product.
- references in this specification to “adsorbed starch granule” refers to a porous starch granule to which an emulsion compound has been adsorbed.
- the emulsion composition adheres to an outer surface of the starch granule.
- the emulsion composition occupies dimples or concave areas on the surface of the starch granules.
- the emulsion composition occupies passageways that traverse the interior portion of the granule.
- An adsorbed starch granule is generated when an emulsion compound is adsorbed onto a porous starch granule.

- the total amount of oil present in the samples was determined on a full evaporation technique headspace gas chromatography/flame ionizing detector (Agilent GC (7890B)), using a Stabilwax-DA column (30 m x 0.53 mm x 1.5 pm) and helium at 5.0 rnL/min at 5.0 ml/min flow rate. 50 pl of ethyl benzoate was added to 25 ml dimethyl sulfoxide. 500 mg of sample was added, to provide 20-30% by weight of oil. Aliquots of sample preparation were analyzed on the gas chromatograph.
- the inlet settings for the gas chromatograph were: Detection temperature: 240 °C; Injection Mode: Split Pressure: 3.791 psi; Split Ratio: 20: 1 Split Flow: 100 ml/min; Total Flow: 108 ml/min Septum Purge Flow: 3 ml/min.
- the oil-loaded porous starch granules (Plated oil as is) retained about 70% of the oil in the composition.
- the oil-loaded porous starch granules retained less than 20% of the oil in the oil solution, suggesting that the oilloading performance of porous starch granules is decreased with aging.
- porous starch particles When oil compositions were made into an oil emulsion composition prior to plating onto the porous starch granules, then the porous starch particles (Plated emulsion) retained over 80% or 90% of the oil in the oil solutions, showing a significant improvement in the amount of oil retained by the particles. While the porous starch particles still retained greater amounts of fresh oil compared to aged oil, the particles still retained a greater amount of oil that was applied as an oil emulsion composition compared to the plated oil emulsion (plated oil as is).
- oil emulsion compositions were spray dried (Spray dried), the oilcontaining starch materials retained about 80% of the oil, and retained fresh oil and aged oil in similar amounts.
- Example 9 Sensory evaluations of oil-loaded starch compounds Each of the oil-loaded starch particle compositions made in Figure 9 and Table 10 was subjected to sensory evaluations provided by a panel of trained sensory analysts.
- a panel of 8 highly trained human panelists evaluated each set of samples, each following the same sensory protocol.
- the samples were evaluated at room temperature conditions (70°F/20°C), with each panelist using their nose to smell each sample.
- the samples were assessed for intensity of aroma on a 15 point Universal Intensity Scale, for the intensity of overall citrus aroma and oxidized aroma, where the intensity of each aroma was assessed on a scale between 1 (least intensity) to 15 (greatest intensity).
- the averages or means of the scores are reported in Figure 10 and Table 11.
- compositions delivering oxidized aromas of equal or lesser intensity than that of the corresponding overall citrus aroma except Plated oil as is (Aged).
- the loading solutions that contained fresh oil generated lower intensity scores for oxidized aroma, when compared to counterparts that were aged.
- the oil emulsion plated onto porous starch granules method delivered the combination of highest intensity levels of overall citrus aroma and lowest intensity levels of oxidized citrus aroma. This phenomenon was observed when the blended compositions were tested as fresh or aged, although the fresh oil delivered greater contrasts between the different aromas.
- the oil emulsion plated onto porous starch granules method provides for loading and retaining greater amounts of oil onto starch carriers (using spray-drying or plating-porous methods), and the resulting starch particle carriers (whether fresh or aged) contemporaneously delivering a superior sensory experience (greater intensity of desired overall citrus aroma coupled with lesser intensity of unwanted oxidized aroma) when compared to directly loading oil (in the absence of an emulsifying agent) onto porous starch granules, and versus spray-drying. That is, current methods used to load oil onto starch particle products were improved when instead of loading oil directly to starch particles, the oil was loaded as part of an oil- and-liquid emulsion. But the other new methods provided even better results.
- the methods used to load the oil emulsion onto starch particles also made a difference in the particles’ ability to retain oil and to deliver aromas.
- Both spray-drying and plating onto porous starch granules were methods that provided products that absorbed significant percentages of the oil applied.
- there was a measurable loss in the amount of oil retained by the spray-dried starch powder (though the amounts of oil retained remained over 70% of the oil applied).
- the porous-plated emulsions achieved total or near total retention of fresh oil applied to it, as well as delivering a superior sensory experience (a greater intensity of desired overall citrus aroma coupled with lesser intensity of oxidized aroma), when compared to the spray-dried starch products.
- the improved delivery of oil was demonstrated when the final product composition contained water.
- Orange oil blend was loaded onto different types of starch products using different methods: i) applying oil compounds onto non-porous starch particles: ii) incorporating oil compounds into oil-and-liquid emulsions and loading them onto non-porous starch products; and iii) incorporating oil compounds into oil-and-liquid emulsions and loading them onto porous starch particles.
- Each of the oil-loaded starch compositions made in Figure 9 and Table 10 was assessed for its ability to retain the oil compounds loaded onto them, and for the intensity of preferred aromas and unwanted off-notes delivered by the oil compounds.
- Figure 10 and Table 11 assessed the same compositions for their capacity to deliver desired aromas and undesired off- note aromas.
- the samples were tested for amount of oil present, intensity of overall citrus aroma, and intensity of oxidized aroma. They samples were tested when freshly prepared and after being subjected to conditions that simulated shelf-life aging, to determine whether these properties persisted with time and continued to protect the active ingredients over the shelf-life of the experimental products.
- the sensory data confirms that the methods described herein provide an increase in the protection of the active ingredients present in oil compounds, when oil compounds are stored on starch particles. And surprisingly, the improved stability was demonstrated when the final product composition contained water.
Abstract
The present invention relates to a method of delivering stable oil-in-water emulsions onto porous starch particles and providing stable free-flowing particles that have the emulsions adsorbed onto them, and to the stable, free-flowing compositions thus provided. The emulsions are used to deliver active ingredients to the starch particles in a range of particle sizes. The emulsion-loaded compositions exhibited increases in amount of oil loaded and delivery of improved odor profiles, features that persisted over their shelf-life. Such compositions provide a cost-effective and sustainable approach for delivering active ingredients, especially oil- and water-soluble active ingredients, and for incorporating such active ingredients into other compositions. This approach circumvents the spray drying or high temperature requirements for other existing methods, and provides oxidation protection to sensitive active ingredients used in flavor, fragrance, nutritional, and other applications.
Description
FREE-FLOWING PLATED POROUS STARCH GRANULES AND METHODS OF MAKING
The technology disclosed in this specification pertains to a method of adsorbing an active ingredient onto free-flowing porous starch granules, to provide free-flowing porous starch granules with the active ingredient adsorbed or plated onto them. The method relates to introducing the active ingredient in an oil-and-liquid emulsion to facilitate its adsorption to the porous starch granules. The adsorbed free- flowing porous starch granules are useful for storing and delivering oil-based ingredients for use in a variety of edible, industrial, and pharmaceutical compositions.
Many compositions have a dry. solid form and are made of dry ingredients, where the addition of a liquid ingredient will destroy the dry, solid form of the composition. One strategy for introducing liquid components to such a dry, solid mixture is to plate the liquid onto free-flowing porous starch granules - the granules adsorb the liquid, but retain a dry, solid, and free-flowing form - thus allowing the incorporation of the liquid without losing the dry, solid form of the composition.
However, there are limitations to this strategy. Not all liquids can be plated successfully. And some liquids may be plated successfully but suffer a decrease in shelf life or some loss or impairment of physical, biological, or chemical activity or property. And even where plating is a suitable method, currently there is typically a limit to the amount of liquid that can be plated onto the porous starch granules; if too much liquid is added, the granules agglomerate into clumps or even into a solid mass. This provides physical constraints on the amount of liquid material that can be thus loaded.
There is a strong demand in the food, beverage, beauty and home care, pharmaceutical, animal feed, and other industries to provide an active ingredient, such as a flavorant, nutrient, or fragrance, in an emulsifying compound and deliver the active ingredient in the form of a free-flowing powder, typically for incorporation into another product for commercial use. Thus, the active ingredient is stored or delivered as a free-flowing powder, which provides reductions in manufacturing, storing, and delivery costs, and protects or extends the performance and shelf-life stability of the active ingredient. However, there is a demand for the delivery of larger amounts of active ingredients in a shelf-stable form.
This specification describes a method of transferring active ingredients onto porous starch granules, by including the active ingredient as part of an oil-and-liquid
emulsion for delivery to the porous starch granules, and for protecting the activity of the active ingredients over time. Some methods are performed in the absence of heat, to prevent exposure to an environmental condition that damages or impairs the stability and activity of some active ingredients. This specification also describes free- flowing porous starch granules loaded with active ingredients whose functionality is protected over time, and to uses of the adsorbed porous starch granules in a variety of compositions. This specification also discloses compositions comprising the adsorbed porous starch granules.
Such adsorbed porous starch granules can be used to convert liquid emulsions into easy-to-handle, free flowable powders without the need of spraydrying or freeze-drying steps or equipment, or application of other drying technology, which can reduce the capital expense, maintenance, and energy costs associated with equipment. Such granules also convert liquid compositions into a dry powder form that is easily stored and transported. By plating active ingredients in the presence of an emulsifying agent, amount of active ingredient delivered in increased and the shelf life, stability, and chemical or biological activities of the active ingredients are protected or extended.

Definitions
The subject matter described in this specification can be better understood with reference to the following definitions and other guidance for construing the terms in this specification.
The term "polysaccharide" as used herein refers to starches, gums, dextrins, celluloses, and heteropolysaccharides, and derivatives thereof, hydrolysates thereof, crosslinked products thereof and combinations thereof. Where one polysaccharide is used as a material, another polysaccharide may substitute for it in other embodiments.
Reference to the term “porous starch granule”, used interchangeably with “porous starch particle”, refers to a starch product that has multiple pores or concave portions or depressions on its exterior surface, that increase the surface area when compared to a smooth starch granule of similar size and overall dimension, as show n by scanning electron microscopic techniques. Some indentations are present as dimples or dents on the surface of the granule, which form concave portions at a single location on the granule. Some indentations are present as passageways that traverse the interior of the granule, and connect openings at least two locations on the granule. The pores and passageways are present in a range of sizes and dimensions, to provide a starch granule with an uneven exterior surface.
A porous starch granule is a particulate substance with porous adsorption properties. Porous starch granules absorb wet/liquid substances maintaining their dry substance. Native starch is made of amylopectin and amylose, which together form a
densely packed crystalline structure known as a granule. Porous starch particles or granules differ from native starch granules in that chemical or physical treatments of the native starch causes the formation of an increased volume of pores on its surface, giving it a sponge-like structure that creates adsorbancy where typical native nongelatinized starches have little to none. This feature also increases the surface area of a porous starch particle, compared to a native starch particle of the same size, (e.g., powder) while adsorbing the substances. Porous starch granules are generated, for example, when granular starch is modified by enzymatic degradation and/or crosslinking processes. Porous starch granules are also generated by other processes, such processes providing a large specific surface area to the modified starch granules.
A starch product may contain porous starch granules, non-porous starch granules, or a mixture thereof.
Reference in this specification to “free-flowing” starch or other materials refers to dry or solid materials that are amenable to pouring. Free-flowing starches may exhibit an ease of flow that is comparable to a liquid, to move with a liquid-like motion, not to gather in clumped masses.
Reference in this specification to “aqueous component” refers to a component comprising water regardless of its phase (solid, liquid, gaseous, etc.). Aqueous components may comprise other ingredients which are suspended, dispersed, dissolved, or otherwise mixed in the aqueous component. Aqueous components have various pHs.
Reference in this specification to “emulsion composition” refers to a mixture containing at least oil, another liquid, and an emulsifying agent. An “emulsifying agent” is a substance that facilitates the mixture of two or more liquids that are normally immiscible with each other (e.g., oil and water). In some applications, one or more components of the emulsion composition comprise an active ingredient; in some applications, an emulsion composition contains an additional ingredient that contains an active ingredient.
Reference in this specification to “active ingredient” refers to a composition that possesses a physical, chemical, or biological activity. An active ingredient is a composition whose delivery is desired for its ability to cause or enhance any desired effect upon or after delivery as part of another product.
Reference in this specification to “adsorbed starch granule” refers to a porous starch granule to which an emulsion compound has been adsorbed. In some
circumstances, the emulsion composition adheres to an outer surface of the starch granule. In some circumstances, the emulsion composition occupies dimples or concave areas on the surface of the starch granules. In some circumstances, the emulsion composition occupies passageways that traverse the interior portion of the granule. An adsorbed starch granule is generated when an emulsion compound is adsorbed onto a porous starch granule. The porous starch granules comprise a plurality of free-flowing particles or granules. After an emulsion compound is adsorbed, the adsorbed starch granules retain their free-flowing particle or granule form.
Reference in this specification to “particle size” refers to the size distribution of particles or granules in a composition. Particle size is measured using laser scattering and may be done using any suitable apparatus. Where an emulsion composition is adsorbed onto porous starch granules, the particle size indicates the amount of oil, water, or other component of the emulsion composition loaded onto the adsorbed starch granules. Particle size also provides a guide as to saturation of the starch granules dunng the plating process, as such particles aggregate and form larger particles. Within this specification particle size is measured using of a Beckman Coulter particle size analyzer, which measures particle size using laser diffraction (ranges from 0.2 pm - 1600 pm). Particle sizes reported in this specification are in microns and refer to the diameter of the referred-to particle or granule in the distribution. Mean particle sizes reported are volume weighted mean particle size sometimes called a volume mean particle sizes or a D4,3 means.
Reference in this specification to “soluble” content means a sample of solids that is dissolvable in solution. Within this specification it measured by reference to the percent of a portion of a sample that has dissolved solution. Most commonly in this specification, soluble refers to the percent of starch that has dissolved in aqueous solution. The soluble content is not intended to be an absolute but is taken relative to other conditions.

The technology' disclosed in this specification can be better understood with reference to the following aspects, which are not intended to limit the full scope of the described technology .
Tn one aspect, the technology disclosed in this specification pertains to a free-flowing, starch granule product made of a plurality of free-flowing porous starch granules having adsorbed to them an emulsion compound containing an active ingredient. In addition to the active ingredient, the emulsion compound comprises an oil-based component, an aqueous component, and an emulsifying agent which is believed to facilitate the delivery' of the active ingredient to the porous starch granules such that the adsorbed granules retain their free-flowing, powder-like form (compared
to agglomerating into a solid or cohesive mass). Thus, the resulting adsorbed porous starch granules retain their state as free-flowing solid particles, but with a desired active ingredient adsorbed to individual particles.

In any embodiment, the active ingredient is delivered to porous starch granules in the presence of an emulsion compound. Typically, the emulsion compound comprises an oil-based component, an aqueous component, and an emulsifying agent. Emulsifying agents are known to stabilize a liquid-oil interface, by a variety of mechanism, such as by maintaining small oil droplet size within the aqueous portion, or by the emulsifying agent providing a coating around oil droplets to provide encapsulated active ingredients.

It is well-known that starches can be modified by a variety of processes, including but not limited to physical, mechanical, pressure, temperature, chemical, and enzymatic processes, and combinations thereof. In any embodiment, the starch product is physically modified by physical factors including, but not limited to, physical factors such as milling, grinding, micronization, shearing, moisture, temperature, thermal heating, non-thermal heating, moisture treatment, pressure, pH, radiation, pulse-electric field, and ultrasonic waves.

Preparation of Emulsion Compositions;
Generally, an emulsion composition comprises an oil, water or other liquid, and emulsifier (or emulsifying agent). The emulsifier is dispersed in a water phase, which can contain one or more buffering agents (e.g., sodium benzoate, citric acid). Then, a pre-emulsion composition is prepared by slowly adding the oil or oil blend to the water phase dispersion in an LCI high shear mixer (e.g., Model HSM-100 LCI from Charles Ross & Son Company), with stirring (e.g., at 5000 rpm for 2 minutes). An exemplary pre-emulsion formulation is provided in Table 1. The pre-emulsion composition is subsequently homogenized by at least two passes through an APV pressure homogenizer (e.g., Model 15 MR Laboratory Homogenizer from APV Gaulin); this is done to obtain a desired particle size based on application (e.g., coarser (1-5 micron) or finer (0.3-1.0 micron)). Examples of pressure settings used include: i) the second stage set at 500 psi and the first stage set at 3000 psi; and ii) the second stage set at 500 psi and the first stage set at 4500 psi. The pressure can be varied based on active ingredients used and application requirements.
In some embodiments, one or more components of the emulsion composition comprise an active ingredient. Any of the oil, liquid, or emulsifying agent can be an active ingredient. In any embodiment, the emulsifying composition comprises an additional ingredient that acts as an active ingredient.
The oil may be present in the emulsion composition in any desirable amount possible and for any desired oil load, the oil load being the amount of oil present in the liquid phase of the emulsion composition. The type and amount of oil present will depend upon many parameters, but specifically can be altered to provide amounts of emulsifier product recommended in the desired applications. The emulsifier: oil ratio of the emulsion may also be any desired ratio and will also depend upon many parameters. In one example, the emulsifieroil ratio is 0.5 : 1 or 1: 1, orl:3 or 1:4 or
1 :6. Preferably, the emulsifier: oil ratio is any ratio suitable for food and beverage applications.
Example 1 (emulsion preparation)
An emulsion composition, made according using the pre-emulsion formulation of Table 1, was prepared by dissolving 0.15% sodium benzoate in water, then by adding 0.3% citric acid in water, and then adding 35% Q-NATURALE® saponin extract (as an emulsifying agent) in a 0.15% sodium benzoate solution at room temperature with moderate stirring. An emulsion composition was thus provided. A pre-emulsion composition was prepared using a high shear mixer (LCI high shear mixer), by slowly adding 50% (5 -fold) orange oil into the emulsion mixture. The pre- emulsion composition was homogenized using a high-pressure homogenizer (APV), with 2 passes on the APV. Here, the following APV settings used were: 1st stage = 4500 psi, and 2nd stage = 500 psi. The particle size of the resulting prepared emulsion composition was measured by Beckman Coulter particle size analyzer. For this example, as shown in Figure 1, the mean particle size obtained for the pre-emulsion composition was about 1 micron, while the mean particle size obtained for the emulsion composition was about 0.1-0.15 microns when freshly made and after storage at 57°C for 24 hours.
Example 2 (plating preparations)
The emulsion composition described in Example 1 was plated onto porous starch particles. The emulsion composition was made using the ingredients listed in Table 1. To do this, 25 gm of N-ZORBIT® 2144 starch particles was weighed, and
then slowly added to the emulsion composition made with Q-NATURALE® emulsifier, with constant mixing using a mixer (e.g., Hobart mixer). The resulting slurry mixture was observed periodically until a paste form was reached, to determine the maximum plating capacity of the system. The mean particle size of the samples was also periodically measured, using the Beckman Coulter particle size analyzer.
Additional pre-emulsion compositions were prepared, each made with different amounts of oil to provide a 50% oil load with the orange oil. Emulsion compositions were made by applying the pre-emulsion compositions to N-ZORBIT 2144® plating agent, to load different amounts of oil onto the porous starch particles, as shown in Table 2.
As shown in Figure 2, emulsion compositions possessing oil loads between about 14-23% were plated or adsorbed onto the porous starch particles, providing plated or adsorbed starch particles that retained their flowable, solid state. As shown in Figure 3, the mean particle size measured for untreated porous starch granules was about 65- 75 microns, while the mean particle size obtained after emulsion compositions were adsorbed onto the porous starch granules was between about 200-800 microns.
Example 3 (emulsion preparation and plating preparation)
An emulsion composition was prepared according to the formulation provided in Table 3, using a high shear mixer (LCI high shear mixer), by slowly adding a medium chain triglycerides oil into a mixture of the aqueous phase ingredients. The pre-emulsion solution was homogenized using a high-pressure-homogenizer (APV), with 2 passes on the APV. For this example, a 41.2% oil load was provided and the APV settings used were: 1st stage = 4500 psi, and 2nd stage = 500 psi. The particle
size of the resulting prepared emulsion composition was measured by Beckman Coulter particle size analyzer, shown in Figure 4. For this example, the mean particle size was less than about 0.8 micron when fresh and about 1 micron after aging at 50°C for 24 hours. Different amounts of the emulsion composition were plated onto N-ZORBIT® 2144 plating agent starch particles to provide plated starch particles that retained their flowable, solid state (Figure 5, showing a negative control (N-ZORBIT® 2144 only) and N-ZORBIT® 2144 plated with about 25% or about 50% oil load).
Example 4 (emulsion preparation and plating preparation)
An emulsion composition was prepared by according to the formulation provided in Table 4, using a high shear mixer (LCI high shear mixer), by adding a PURITY GUM® Ultra OSA starch, and then maltodextrin into the emulsion mixture, providing 41.2% of the final emulsion composition. The medium chain trigly cerides was slowly added using a high shear mixer.
For this example, a 70% oil load was provided by the medium chain triglycerides and the APV settings used were: 1st stage = 4500 psi, and 2nd stage = 500 psi.
The particle size of the resulting prepared emulsion composition was measured by Beckman Coulter particle size analyzer, shown in Figure 6. For this example, the mean particle size was less than about 2.9 microns when fresh and about 3.7 microns after aging at 50°C for 24 hours. Different amounts of the emulsion composition were plated onto N-ZORBIT® 2144 starch particles to provide plated starch particles that retained their flowable, solid state (Figure 7, showing a negative control (N-ZORBIT 2144® only) and N-ZORBIT® 2144 plated with about 10-20% oil load).
Different amounts of the emulsion composition were plated onto porous starch particles. To do this, 25 gm of N-ZORBIT® 2144 plating agent was weighed, and then slowly added to the emulsion composition made with medium chain triglycerides, OSA starch, and maltodextrin, with consistent mixing using a mixer (e.g., Hobart mixer). The resulting slurry was observed periodically until the paste form was reached, to assess the maximum plating capacity of the system. The mean particle sizes of the sample were also periodically measured, using the Beckman Coulter particle size analyzer, as shown in Figure 8, were the plated porous starch particles achieved mean particle sizes between about 480-870 microns.
As shown in Figures 2, 5, and 7, emulsion compositions were plated or adsorbed onto the porous starch particles, providing plated starch particles that retained their flowable, solid state. The porous starch granules were plated with amounts of emulsifying compositions that provided oil loads of about 8-22% on the plated or adsorbed porous starch granules, while the plated or adsorbed porous starch granules retained their flowable state. Further, the porous starch granules accepted loads of emulsion compositions that provided between about 16-49% of the weight of the free-flowing adsorbed starch particle composition.
As shown in Figures 3 and 8, the free-flowing adsorbed starch particle composition possessed increasingly larger particle sizes, when adsorbed to correspondingly greater amounts of emulsion compositions. Here, mean particle sizes between about 190-870 microns were measured.
Example 5: Emulsion for plated application Experiment 1
An emulsion composition, made using the pre-emulsion formulation according to Table 5, was prepared by dissolving 0.15% sodium benzoate in water, then by adding 0.3% citric acid in water, and then adding 12% Purity Gum 2000® starch (as an emulsifying agent). A pre-emulsion composition was prepared using a high shear mixer (LCI high shear mixer), by slowly adding 16% of a blended oil mixture (1 -fold orange oil and MCT in an 80:20 ratio) into the mixed emulsion ingredients. The pre- emulsion composition was homogenized using a high-pressure homogenizer (APV) device, with 2 passes on the APV. Here, the following APV settings used were: 1st stage = 4500 psi, and 2nd stage = 500 psi.
The emulsion composition described in Experiment 1 was plated onto porous starch particles of N-ZORBIT® 2144 as follows: 50 gm of N-ZORBIT® 2144 starch particles was weighed, and then 27.0 gm of the emulsion composition (made with Purity Gum® 2000 emulsifier) was slowly added to the starch particles, with constant mixing using a proper mixer, using the ingredients and proportions recited in Table 6. The resulting slurry mixture was visually observed periodically to determine the maximum emulsion plating capacity of the oil-loaded starch particles.
Example 6: Emulsion for spray dry application Experiment 2
An emulsion composition of 4.5% flavored oil was made according to the formulation of Table 7 by adding 29.0% Purity Gum 2000® (as an emulsifying agent) into water. A pre-emulsion composition was prepared using a high shear mixer (LCI high shear mixer), by slowly adding 1.76% of oil blend (1-fold orange oil and MCT in an 80:20 ratio) into the emulsion mixture. The pre-emulsion composition was homogenized using a high-pressure homogenizer (APV), with 2 passes on the APV. Here, the following APV settings used were: 1st stage = 4500 psi, and 2nd stage = 500 psi.
The homogenized emulsion composition was spray-dried using an inlet temperature of 160-180°C and outlet temperature of 85-95°C. The resulting oil- loaded, spray-dried composition was a powder composed of the ingredients and proportions recited in Table 8.
Example 7: Plated oil as is (80% 1-fold orange oil +20% MCT) Experiment 3
As shown in Table 9, a formulation was made as follows: 50 gm of N- ZORBIT® 2144 starch particles was weighed, and then 3.0 gm of oil blend (a mixture of 2.4 gm 1-fold orange oil and 0.6 gm of MCT) was slowly added with constant mixing using a proper mixer. The resulting slurry mixture was visually observed periodically to determine the oil plating capacity of the oil-loaded starch particles (when oil was loaded directly, in the absence of an emulsifying agent).
Table 9
The resulting powdered solids obtained from Examples 5-7 were analyzed for oil protection, stability, and for quality of sensory attributes. These experiments were performed with oil solutions that were prepared fresh and frozen until testing, or age- accelerated at 50°C for 15 days (to provide samples representative of samples exposed to a 6-month shelf-life cycle).
Example 8: Gas Chromatography analysis (Absolute Oil Retention)
The resulting solid powders obtained from Examples 5-7 were analyzed for oil protection. That is, known amounts of oil were loaded onto starch particles using a variety of methods and materials. After the loading processes were complete, the samples were evaluated by gas chromatography to determine the amount of oil that was loaded onto the samples, expressed as a percentage of the total amount of oil loaded.
Oil compositions or oil emulsion compositions were loaded onto starch particles via plating or by spray-drying. The experiments were performed using oil- loaded starch compositions that were prepared fresh or were aged at 50°C for 15 days. The same oil blends were plated onto porous starch granules (N-ZORBIT 2144) directly (Plated oil as is), or were suspended in an emulsion, which was then plated onto porous starch granules (Plated emulsion). Oil compositions were emulsified with hydrophobic starch product (Purity Gum 2000) and subjected to spray drying (Spray dried). After the oil compositions or oil emulsion compositions were plated or loaded onto starch granules, the amount of oil retained by the treated starch granules was measured by gas chromatographic analysis and reported as a percentage of the oil applied to the starch particles, as shown in Figure 9 and in Table 10.
The total amount of oil present in the samples was determined on a full evaporation technique headspace gas chromatography/flame ionizing detector (Agilent GC (7890B)), using a Stabilwax-DA column (30 m x 0.53 mm x 1.5 pm) and helium at 5.0 rnL/min at 5.0 ml/min flow rate.
50 pl of ethyl benzoate was added to 25 ml dimethyl sulfoxide. 500 mg of sample was added, to provide 20-30% by weight of oil. Aliquots of sample preparation were analyzed on the gas chromatograph. The inlet settings for the gas chromatograph were: Detection temperature: 240 °C; Injection Mode: Split Pressure: 3.791 psi; Split Ratio: 20: 1 Split Flow: 100 ml/min; Total Flow: 108 ml/min Septum Purge Flow: 3 ml/min. The flame ionizing detector settings were: Detector Temperature: 240°C Hydrogen Flow: 30 mL/min Air Flow: 400 mL/min; Helium Make-Up Flow: 25 mL/min Samples were analyzed in triplicate (n = 3), with mean values reported in Figure 9 and Table 10.
When fresh, the oil-loaded porous starch granules (Plated oil as is) retained about 70% of the oil in the composition. When aged, the oil-loaded porous starch granules retained less than 20% of the oil in the oil solution, suggesting that the oilloading performance of porous starch granules is decreased with aging.
When oil compositions were made into an oil emulsion composition prior to plating onto the porous starch granules, then the porous starch particles (Plated emulsion) retained over 80% or 90% of the oil in the oil solutions, showing a significant improvement in the amount of oil retained by the particles. While the porous starch particles still retained greater amounts of fresh oil compared to aged oil, the particles still retained a greater amount of oil that was applied as an oil emulsion composition compared to the plated oil emulsion (plated oil as is).
When the oil emulsion compositions were spray dried (Spray dried), the oilcontaining starch materials retained about 80% of the oil, and retained fresh oil and aged oil in similar amounts.
Two of the experimental methods employed provided similar initial delivery of oil onto starch granules: spray dry ing of oil emulsion compositions and plating of oil emulsion compositions onto porous starch granules. These methods also showed retention of similar amounts of oil when aged.
Example 9: Sensory evaluations of oil-loaded starch compounds
Each of the oil-loaded starch particle compositions made in Figure 9 and Table 10 was subjected to sensory evaluations provided by a panel of trained sensory analysts.
A panel of 8 highly trained human panelists evaluated each set of samples, each following the same sensory protocol. The samples were evaluated at room temperature conditions (70°F/20°C), with each panelist using their nose to smell each sample. The samples were assessed for intensity of aroma on a 15 point Universal Intensity Scale, for the intensity of overall citrus aroma and oxidized aroma, where the intensity of each aroma was assessed on a scale between 1 (least intensity) to 15 (greatest intensity). The averages or means of the scores are reported in Figure 10 and Table 11.
The same samples, which were loaded with orange oil, were assessed for the intensity of two scents delivered by the samples: the overall citrus aroma, which is the desired “orangey” scent associated with citrus fruits, and the oxidized aroma, which is an unwanted off-note associated with degraded oil compounds.
Regarding the assessment of overall citrus aroma, when fresh orange oil compositions were loaded onto starch particles, all of the methods provided measurable intensity of overall citrus aroma for the experimental samples, though the oil emulsion plated onto porous starch granules delivered the overall citrus aroma of greatest intensity to the panel of sensory analysts. The only method that provided samples yielding low or no intensity scores for overall citrus aroma was for aged matrixes of oil compositions plated onto porous starch granules (Plated oil as is (Aged)).
When oil was loaded onto starch particles, using the methods described above, and then aged, smaller intensities of overall citrus aroma was reported by the sensory panelists. However, the methods with aged oil emulsion compositions and starch
particles mixtures (plated emulsion (Aged) and Spray dried (Aged)), generated samples that delivered significantly greater intensities of overall citrus aroma. In comparison, the aged oil composition (plated oil as is (Aged)), delivered as an oil and not as part of an oil emulsion, generated samples that had little or no intensity of overall citrus aroma.
Regarding the assessment of oxidized aroma, the results reported by the sensory panel are generally reversed, compared to the assessment of overall citrus aroma. Most of the methods provided compositions delivering oxidized aromas of equal or lesser intensity than that of the corresponding overall citrus aroma, except Plated oil as is (Aged). The loading solutions that contained fresh oil generated lower intensity scores for oxidized aroma, when compared to counterparts that were aged.
The oil emulsion plated onto porous starch granules method delivered the combination of highest intensity levels of overall citrus aroma and lowest intensity levels of oxidized citrus aroma. This phenomenon was observed when the blended compositions were tested as fresh or aged, although the fresh oil delivered greater contrasts between the different aromas.
Taken together, the oil emulsion plated onto porous starch granules method provides for loading and retaining greater amounts of oil onto starch carriers (using spray-drying or plating-porous methods), and the resulting starch particle carriers (whether fresh or aged) contemporaneously delivering a superior sensory experience (greater intensity of desired overall citrus aroma coupled with lesser intensity of unwanted oxidized aroma) when compared to directly loading oil (in the absence of an emulsifying agent) onto porous starch granules, and versus spray-drying. That is, current methods used to load oil onto starch particle products were improved when instead of loading oil directly to starch particles, the oil was loaded as part of an oil- and-liquid emulsion. But the other new methods provided even better results.
Further, the methods used to load the oil emulsion onto starch particles also made a difference in the particles’ ability to retain oil and to deliver aromas. Both spray-drying and plating onto porous starch granules were methods that provided products that absorbed significant percentages of the oil applied. However, there was a measurable loss in the amount of oil retained by the spray-dried starch powder (though the amounts of oil retained remained over 70% of the oil applied). In comparison, the porous-plated emulsions achieved total or near total retention of fresh oil applied to it, as well as delivering a superior sensory experience (a greater
intensity of desired overall citrus aroma coupled with lesser intensity of oxidized aroma), when compared to the spray-dried starch products. And surprisingly, the improved delivery of oil was demonstrated when the final product composition contained water.
Example 10: Stability of oil-loaded starch compounds
Orange oil blend was loaded onto different types of starch products using different methods: i) applying oil compounds onto non-porous starch particles: ii) incorporating oil compounds into oil-and-liquid emulsions and loading them onto non-porous starch products; and iii) incorporating oil compounds into oil-and-liquid emulsions and loading them onto porous starch particles. Each of the oil-loaded starch compositions made in Figure 9 and Table 10 was assessed for its ability to retain the oil compounds loaded onto them, and for the intensity of preferred aromas and unwanted off-notes delivered by the oil compounds. Figure 10 and Table 11 assessed the same compositions for their capacity to deliver desired aromas and undesired off- note aromas.
The samples were tested for amount of oil present, intensity of overall citrus aroma, and intensity of oxidized aroma. They samples were tested when freshly prepared and after being subjected to conditions that simulated shelf-life aging, to determine whether these properties persisted with time and continued to protect the active ingredients over the shelf-life of the experimental products.
All samples took on measurable amounts of oil initially, and all samples possessed smaller amounts of oil after aging, though the plated emulsion group contained the largest amounts of oil initially. The other experimental groups exhibited the greatest losses of oil over time.
In addition to measuring the amount of oil physically delivered to the starch products, functional aspects of the oil compound were also tested. The same samples, which had been loaded with orange oil, were assessed for intensity of two citrus scents delivered by the samples: the overall citrus aroma, which is the “orangey” scent associated with citrus fruits and the oxidized aroma, which is an off-note associated with degraded oil compounds.
Just as all samples took on measurable amounts of oil, all samples also delivered measurable amounts of aroma intensities. Most of the samples delivered greater intensities of overall citrus aroma than oxidized aroma.
With aging, all samples generally exhibited a decrease in overall citrus aroma intensity and an increase in oxidized aroma. The most marked change was observed where the oil was delivered without being part of an emulsion. Those samples exhibited an oxidized aroma intensity that far exceeded the overall citrus aroma intensity. In contrast, the other experimental groups retained a significant overall citrus aroma intensity. Of these groups, one (oil emulsion plated onto nonporous particles) retained a greater overall citrus aroma intensity and smaller oxidized aroma intensity. In other words, with aging, the plated emulsion group retained the most “good” smell and the least “bad” smell of the samples.
In addition to the gas chromatography results, the sensory data confirms that the methods described herein provide an increase in the protection of the active ingredients present in oil compounds, when oil compounds are stored on starch particles. And surprisingly, the improved stability was demonstrated when the final product composition contained water. We report improvements in known methods, and report novel methods (loading oil-and-liquid emulsions onto porous starch particles) that provide superior protection of the active ingredients present in oil compounds, improving the amount and functionality of oil compounds thus delivered, especially when the delivery occurs at a later time, which ultimately improves the shelf-life of these products.
