Description
A method for the manufacture of a flavour-enhancing composition
The present disclosure s to a method for producing a flavour- or taste-enhancing
additive and flavour-enhancing additives produced by said method. Specifically, the present
disclosure s to a method of producing a derived flavour-enhancing composition,
the method comprising nanofiltration of a dairy liquid.
Sodium consumption is an area of keen focus for both health professionals and consumers.
Excess sodium consumption can increase blood pressure leading to an increased risk of
heart disease and . Additionally, 75% of salt (NaCl) intake is derived from sed
foods such as bread, cereal, canned soup, and ready meals. Accordingly, there is a desire
for alternatives to table salt for use in processed foods, in order to reduce ption of
sodium. Sodium intake can be reduced by replacing salt with alternative salty g
Dairy s contain significant proportions of whey protein, lactose and mineral
components. Whey is commonly seen as a waste and is commonly used as an animal feed.
High production volumes and limited further processing results in an environmental disposal
problem and a low commercial value of whey. In past years disposing whey into rivers or
municipal sewage system, spraying onto fields or using it as animal feed were established
practices of cheese and casein manufacturers. However, due to its high environmental
impact authorities have den these methods of disposal or charged high prices in return.
This has led to the development of further processing methods of whey in order to derive
further value from this by-product. Whey protein trates are now commonly used in
confectionary baking and the meat industry due to its nutritive, foaming and gelling
properties. The main component of whey permeate is lactose which can be used in
confectionery production. Lactose is also purified by crystallisation and used in the
pharmaceutical industry.
Accordingly, the whey protein and lactose components are general considered as valuable
components, whereas the mineral content is often seen as an undesirable waste product.
Said mineral component is a potential salt replacement since it ses relatively high
potassium, chloride, calcium and phosphorous content but a low sodium content.

17698645_1 (GHMatters) P111533.NZ
According to a first aspect, the present disclosure provides a method for the tion of a
flavour-enhancing composition, the method comprising the steps of:
i) providing a dairy liquid;
ii) nanofiltrating the dairy liquid to obtain a nanofiltration permeate;
iii) concentrating the nanofiltration permeate by reverse osmosis and/or
evaporation to produce a flavour-enhancing ition, the flavour-enhancing composition
sing at least 50 wt% lactose by dry weight and having a K:Na ratio of at least 2:1,
wherein nanofiltrating the dairy liquid uses a membrane having a molecular weight
cut-off of greater than 300 Da and less than or equal to 800 Da.
As discussed below, the method provides an improved flavour-enhancing composition with a
high e content and a high potassium to sodium ratio. Surprisingly, the method allows
the adjustment of the ratio of lactose to dairy minerals in a single efficient nanofiltration step.
The present sure will now be described r. In the following passages different
aspects/embodiments of the disclosure are d in more detail. Each aspect/embodiment
so defined may be combined with any other aspect/embodiment or s/embodiments
unless clearly indicated to the contrary. In particular, any feature indicated as being preferred
or advantageous may be combined with any other feature or features indicated as being
preferred or advantageous.
The present disclosure relates to a method for the manufacture of a flavour-enhancing
composition. Flavour-enhancing compositions are nown components of food. Flavourenhancing
compositions are not necessarily lves flavoured but instead improve the
flavour of products ning them. Table salt (NaCl) and monosodium glutamate (MSG)
are the two most widely known and used flavour-enhancers. While both are commonly used
they both n significant amounts of sodium. There is a current push for consumers to
reduce their sodium intake and therefore there is a push to find dium alternative
flavour enhancers.
The method of the present invention involves a series of steps. As will be appreciated, it is
necessary to perform these steps in a specific order in order to achieve the beneficial
effects. Nonetheless, in practice the steps may be conducted continuously and therefore
simultaneously.
17698645_1 (GHMatters) P111533.NZ
The method of the present disclosure involves the use of dairy liquids. Specifically, the first
step is the provision of a dairy liquid. A dairy liquid is a liquid obtained from the milk of
mammals, typically cows, sheep, goats and the like. Cow’s milk is the most ent. Dairy
liquids typically comprise whey protein, casein, minerals and lactose, together with any fat
fraction. As such, the definition includes dairy derivatives such as sweet whey, sour whey,
milk protein concentrate, total milk protein concentrate, whey protein concentrate, casein
and the like as long as they are in liquid form.
The dairy liquid is in liquid forms such as solutions and suspensions. These aqueous liquids
are important to allow good homogeneous mixing and for uous processing. The dairy
liquid may be formed by titution of powder ingredients with water.
Typically the starting dairy liquid has a solids content of from 1 to 25wt%, preferably 1 to
15wt% and most preferably 5 to 7wt%. The dairy liquid may optionally be pre-concentrated.
Where the dairy liquid is pre-concentrated it may preferably have a solids content of 5 to
20wt%, preferably 10 to 15wt%, most ably about 12wt%. Preferably whey or UF-
permeates of milk or whey are used, which have a total solids content of 5-7%. If some preconcentrating
is applied, total solids could be increased to 12%.
Preferably the dairy liquid comprises one or more of a milk, a fermented milk, a sweet whey,
an acidic whey, or an ultra-filtration permeate f, more preferably the dairy component
comprises a sweet whey or an acidic whey, or an ultra-filtration permeate thereof.
Whey is the main co-product of the cheese manufacturing process. Approximately 9 L whey
accumulates while producing one kilo of hard cheese and 8 L whey out of soft cheese. When
milk is acidified or treated with enzymes like chymosin, caseins separate from the milk
followed by coagulation. The remaining translucent liquid is called whey and is about 85-
95% of the milk volume.
Depending on the cheese cturing process the composition of whey can vary. Whey
can be classified into sweet or sour whey depending on its pH level. Sweet whey is
produced during manufacturing of hard, semi-hard and soft cheese with enzymes causing
casein coagulation and its l pH is between 5.8- 6.6. The production of fresh cheese like
quark, cream and cottage cheese produces acid whey with a pH around 4.3-5.3 y
c acids or lactic acid producing r cultures were used for casein precipitation.
Around 93 to 95% of whey is water less whether it is sweet or acid whey and contains
17698645_1 (GHMatters) P111533.NZ
water soluble milk components, which are 55% of the milk nutrients. Due to the ent pH
and production sweet and sour whey have differences in the mineral content and in the whey
protein composition.
The mineral content of whey is still seen as a low value by-product. Advantageously the
process of the present invention may be used to produce a valuable flavour-enhancing
additive from this otherwise low value substance.
The second step of the t process is nanofiltrating the dairy liquid to obtain a
nanofiltration permeate. Nanofiltration is a specific type of ne filtration. Membrane
filtration is a pressure driven separation technology and separates according to size. In
membrane tion a liquid feed is supplied to the feed side of a membrane. The rejected
feed is called the retentate, consisting of particles larger than the membrane pore size,
cannot pass through the membrane and, in batch processes, it may be ed back into
the feed vessel. Components which pass the membrane are called permeate or filtrate. The
solute transport across the ne is driven by convective flow due to the applied
re and diffusion due to the concentration gradient between feed and permeate.
Membrane filtration techniques may be categorised by the pore size of the membranes used
or their molecular weight cut-off (MWCO), both methods have limitations. While the pore size
may provide a more precise classification method, in that it gives a specific value, it may be
less accurate in terms of terising the ties of the membrane. There are many
properties which effect the retention value of a given membrane, such as the pH of the feed
and the transmembrane re.
MWCO is characterized as the lowest molecular weight that would be more than 90%
retained by the membrane. The characterization significance is limited because al
properties influence the retention. It gives no further information about the rejection of
molecules having a molecular weight below the MWCO. Since rejection versus molecular
weight plots for nes may not provide sharp cut-off values in some cases it is not
possible to assign a specific value to the MWCO. In such cases membranes may be
characterised by a MWCO range. For example a membrane may be characterised by an
MWCO of 100-200 Da and another may be characterised as a 200-300 Da. Accordingly,
although these membranes are characterised by MWCO , and said ranges overlap
since they share an end point, the skilled person would readily appreciate that said
17698645_1 (GHMatters) P111533.NZ
membranes are different. That is, it is the range that classifies the membrane, rather than
the membrane being selected with an MWCO somewhere in that range.
Microfiltration membranes have the t pore size (>0.1 μm, >500kDa) followed by
Ultrafiltration (0.1-0.01 μm, 1-500kDa) and Nanofiltration (0.01-0.001 μm, 0.1kDa - 1kDa).
Reverse osmosis membranes are without pores and reject all dissolved components while
the pure solvent is able to permeate the membranes (<0.001 μm, <0.1kDa).
ing on the feed being processed, membrane filtration has advantages over other
separation methods. ed to thermal treatments, such as evaporation, it is operated at
low temperatures, which makes it suitable for heat sensitive components. In case of milk
components functional properties of proteins are not denaturized. Since no phase change is
ed the process is less energy demanding compared to condensers and evaporator
units. Additionally, membrane tion has a n but sometimes unpredicted selectivity
due to ent tion and rejection effects such as physical g, electrostatic
exclusion and diffusion. The separation is influenced by several factors such as solution pH,
concentration, ionic strength, the ction of charged components as well as the charge of
the membrane. Additionally, various factors affect the filtration process and product
ties. For example the ed process time, concentration factor and product yield
are especially influenced by the transmembrane pressure, feed composition, membrane
pore size and membrane material.
In the present s nanofiltrating the dairy liquid uses a ne having a molecular
weight cut-off of from 300 Da to 800 Da, preferably 400 Da to 800 Da, more preferably from
700 to 800 Da, most preferably about 750 Da. As discussed above such membranes may be
categorised with an MWCO range rather than a specific value. A specific example of a
suitable nanofiltration membrane is NFG Polyamide TFC membrane from Synder Filtration
which is categorised as having an MWCO of 700-800 Da.
Using a membrane with too low an MWCO leads to permeates with solids mainly composed
of monovalent ions (mainly chloride and potassium) and reduced levels of divalent ions,
lactose and lactic acid. While these solids are described as salty, due to the relatively high
concentration of potassium these permeates yield a slightly bitter off taste which reduces the
er liking. Additionally, low MWCO membranes lead to lower flow rates and increased
processing times.
17698645_1 (GHMatters) P111533.NZ
Surprisingly, the present inventors have found that the use of a ltration membrane with
a larger MWCO yields permeates which are slightly salty, sour and sweet due to the low
rejection values of lactose, lactic acid and minerals. Advantageously the higher lactose
concentration acts as a taste-enhancing component as it may cover the bitterness of the
mineral content. The preferred nes have a better mance due to the higher
permeate flow rates, shorter processing time, high dry matter and the high total
concentration of minerals. Since the composition contains lactose, this permits the use of
less onal sugar when used in other sweetened recipes.
The t inventors have surprisingly found that by using a nanofiltration membrane with a
relatively large MWCO it is possible to obtain a permeate with advantageous e, sodium
and potassium concentrations in a single separation step. Advantageously, the process of
the present invention yields a t which may be used as a salt replacement directly.
Preferably the process of the present invention does not e a lactose crystallisation
step, or the addition of lactose. That is, the process of the present invention yields and
advantageous K:Na ratio and a lactose content which masks the bitterness often associated
with high potassium salts.
ing on the concentration and ition of the feed dairy liquid, the nanofiltration
permeate of the invention has a solids content of at least 0.7% and at most 6%, preferably 1
to 3%.
The third step of the present method is concentrating the nanofiltration permeate by reverse
osmosis and/or evaporation to e a flavour-enhancing composition.
The flavour-enhancing composition has a K:Na ratio of at least 2:1. This can be measured
by known techniques such as ICP-OES DIN EN ISO11885. Preferably the ratio is from 2:1 to
:1, preferably from 3:1 to 7:1 and most preferably about 5:1. The ratio reflects the
ion in the sodium achieved with the obtained flavour-enhancing composition
In order to obtain a solid flavour enhancing composition it is necessary to concentrate the
nanofiltration permeate. Preferably concentration of the nanofiltration permeate is performed
by reverse osmosis.
17698645_1 (GHMatters) P111533.NZ
Optionally the method further comprises a step of drying the flavour-enhancing composition
to form a solid, ably a . Drying may be by freeze-drying or drying or any
other such technique as known in the art.
Advantageously, the NF-retentate of the present method provides a partially demineralised
lactose concentrate. Lactose concentrates may be used as animal feed, even when
relatively low purity. High purity lactose concentrates are of higher value as they may be
used in the pharmaceutical industry as an excipient. Advantageously, the NF-retentate of the
present invention may be of sufficient quality to be of use as an excipient for pharmaceutical
ations without further purification or an expensive process step.
Preferably the flavour-enhancing composition ses at least 50 wt% lactose by dry
weight and having a K:Na ratio of at least 2:1. Preferably the flavour-enhancing composition
comprises by dry weight:
a) 50 to 80 wt.% lactose;
b) 5 to 10 wt.% ium;
c) 0.8 to 2.5wt.% sodium; and
d) the e rions such as chloride, phosphate, lactate, citrate and nonprotein
en (NPN).
Non-protein nitrogen is a term in the art to refer collectively to components such as small
peptides or urea, biuret, and ammonia, which are not proteins but can be converted into
proteins by microbes in the stomach.
Preferably the flavour-enhancing composition comprises between 50 and 80 wt% lactose by
dry weight, preferably from 60 to 70wt%.
Preferably the transmembrane pressure of the nanofiltration step is from 5 to 50 bar,
preferably 25 to 40 bar, preferably about 30 bar. While increasing the transmembrane
pressure can increase flux it has also been found to effect the rejection rates of various dairy
liquid components in different ways.
Preferably nanofiltrating the dairy liquid occurs at a temperature of from 5 to 20°C, preferably
about 10 to 15°C. Alternatively, the nanofiltrating may occur at a temperature of 50 to 55°C.
Advantageously, these temperature ranges reduce bacterial growth.
17698645_1 (GHMatters) P111533.NZ
Preferably nanofiltrating the dairy liquid occurs at a pH of from 4.5 to 6.5, preferably at a pH
of about 6.1.
In a further , the present disclosure provides a flavour-enhancing composition
produced according to the method disclosed herein.
In a further aspect, the present disclosure provides a flavour-enhancing composition
comprising by dry weight:
a) 50 to 80 wt.% lactose;
b) 5 to 10 wt.% potassium;
c) 0.8 to 2.5wt.% ; and
d) the e counterions such as chloride, phosphate, lactate, citrate and nonprotein
nitrogen (NPN).
In a further aspect, the present disclosure provides a comestible item comprising the renhancing
composition disclosed above.
The flavour-enhancing ition of the present invention is particularly suitable for use in
comestible products comprising salt and lactose. For example, the flavour-enhancing
ition of the present invention may be used in biscuits, crackers, cheese and the like.
In particular, the flavour-enhancing composition is suitable for use in fresh cheese, cream
cheese, processed , ayran and the like.
In a r aspect, the present disclosure provides the use of the flavour-enhancing
composition disclosed above as a salt replacement in a comestible item.

Mineral content analysis
A series of experiments were conducted in order to test the effect of MWCO on the mineral
content of the permeate. The dairy liquids used were sweet and sour UF permeate. The
sweet whey permeate is d from the ultrafiltration of various whey streams, mainly from
the production of hard cheese. Sweet UF whey was concentrated via evaporation to around
% of solids. The sour permeate has 5% solids and was generated directly from the low fat
fresh cheese production from the ultrafiltration of fermented milk.
The chemical composition of the sour and sweet ultra-filtrated cheese whey (UF permeate)
are shown in Table 1.

In order to assess the flavour effect of the samples taste tests were performed. The samples
were tasted by internal R&D experts. The permeates were d to adjust a constant
de content representing 0.5% salt (NaCl) lents. The Na content of the reference
was 0.20%, i.e. the milk mineral solutions had about 50-65% less Na for the NFX samples
and 40-55% less for the NFG samples. Permeates produced with NFG or NFX were
compared in independent tasting session because of their ent lactose concentrations
and sweetness perception. NFG permeates were compared to a 0.5% NaCl and 5% lactose
nce solution. A 0.5% NaCl on was used as a reference for NFX permeates. It was
focused on saltiness, ss and bitterness compared to the reference solution. A scale to
describe flavor attributes salty, sour and bitter is shown in table 5.

As demonstrated in the foregoing examples, the NFG permeates are slightly salty, sour and
sweet due to the low rejection values of lactose, lactic acid and minerals. The advantage of
the higher lactose concentration is the coverage of bitterness. NFG membranes have a
better performance due to the higher permeate flow rates, shorter processing time, high dry
matter and the high total concentration of minerals. To use NFG permeates as a salt
replacer in products its high lactose concentration has to be compensated. The additional
lactose of the NFG permeate could be ed out by reducing the sugar contribution from
17698645_1 (GHMatters) P111533.NZ
another source. To obtain statistically reliable data of the NF permeate taste profile, a scale
up is required to produce higher s of permeate for further sensory analysis. A
membrane with an intermediate pore size should be applied to obtain acceptable flow rates
and demineralization of the whey. Higher fluxes during filtration could be obtained by
increasing the transmembrane pressure stepwise over the time or by increasing the
ature.
