Description
INFANT CEREAL PRODUCTFIELD OF THE INVENTION
[0001] The present invention relates to infant cereal products, and uses thereof. In particular, the present invention relates to an infant cereal product with reduced allergenic potential and which reduces the risk of allergy development in infants.
[0002] BACKGROUND TO THE INVENTION
[0003] Newborn infants are usually fed by breastfeeding or by liquid infant feeding formulas, which resemble the content of the milk of the mother as closely as possible. Breastfeeding and / or infant formula administration will typically continue during the first year of the infant’s life.
[0004] However, typically at the age of 4-6 months’ infants develop an interest and a readiness for other foods. Signs for this are that an infant starts to be able to sit and control head movements. It will be able to move food from the front of the mouth to the back, so that the tongue coordination will allow the infant to swallow from a spoon. The introduction of solid foods is important for the infant to build a positive relationship with food. This is the first step to a growing baby, and to developing lifelong healthy eating habits.
[0005] Infant cereals help the infant to experience taste, texture, and nutrition, and provide an important source of energy, carbohydrates, protein, vitamins, and minerals. Typically, the protein source in infant cereals is in the form of cows’ milk powder. Such cereals, however, are less suitable for children with an allergy to cows’ milk.
[0006] Food allergies, of which the first to occur in life is generally cows'milk allergy, are caused, in most cases, by a reaction to proteins in the food. In the early years of life, the immune system is still developing and may fail to develop tolerance to dietary antigens (this may also be described as insufficient induction of oral tolerance) . The result is that the baby or child or young animal mounts an exaggerated immune response to the dietary protein and develops an allergic response to it.
[0007] Apart from its mother's milk, the first dietary proteins generally encountered by human babies are cows'milk proteins and, cows'milk allergy is the most common food allergy in human babies. It is also generally accepted that babies with established cows'milk allergy have an increased risk of developing allergies to other dietary proteins, such as egg and cereal proteins. Such allergies may be of greater concern; while an allergy to cows’ milk proteins usually resolves between the ages of two and five, an allergy to egg and cereal proteins may persist throughout life.
[0008] There is therefore an ongoing need for infant cereals with reduced allergenic potential that are more suitable for babies with an existing cows’ milk allergy. There is similarly an ongoing need for infant cereals that reduce the risk of a milk allergy from developing during infancy, thereby also helping to reduce the risk of other allergies developing in the infant, such as to egg or cereal proteins.
[0009] The infant cereal product of the present invention helps address the above problems.SUMMARY OF THE INVENTION

[0020] Definition of terms
[0021] The term "infant cereal product" refers to food for infants and young children. According to the Codex STAN 074-1981 and EU Directive 2006 / 125 / EC: "Complete infant cereals" are defined as "cereals with an added high protein food which are or have to be prepared for consumption with water or other appropriate protein-free liquid" , as opposed to "standard infant cereals" "which are or have to be prepared for consumption with milk or other appropriate nutritious liquids" .
[0022] Table 1: Definition of two groups of processed cereal-based product for infants and young children along with their reconstitution into a pap.
[0023] In an embodiment of the present invention the finished product may be based on a complete or standard infant cereal product as described above. In an embodiment the finished product is a powder or a pap (reconstituted as defined above) . Preferably, the infant cereal product is in the form of a powder. More preferably, the infant cereal product of the invention is a complete infant cereal powder where only water is required for its reconstitution.
[0024] The infant cereal product of the invention also preferably comprises less than about 6 wt. %water, preferably less than about 5 wt. %water, and more preferably less than about 3 wt. %water.
[0025] An “infant cereal product” of the present invention generally comprises a carbohydrate source, a protein source, and a lipid source. The infant cereal product may further comprise a number of other ingredients, including fortifying vitamins and minerals, probiotics, and enzymes.
[0026] The term "degree of hydrolysis" or "DH" of a protein means the number of peptide bonds in the intact protein which are cleaved during the hydrolysis divided by the number of peptide bonds in the intact protein expressed as a percentage. Degree of hydrolysis may be measured by the TNBS method according to Adler-Nissen (J. Agric. Food. Chem. 27: 1256-1262, 1979) .
[0027] The term "amylolytic enzymes" as used herein refers to any enzyme capable of converting starch into dextrins and sugar (mono-or disaccharides) . Examples of amylolytic enzymes include amylases, glucoamylases, and pullulanase. Preferred examples of amylases include alpha-amylases, beta-amylases, gamma-amylases.
[0028] The term “probiotics” are defined for the purpose of the present invention as "Microbial cell preparations or components of microbial cells with a beneficial effect on the health or well-being of the host. " (Salminen S, Ouwehand A. Benno Y. et al "Probiotics: how should they be defined" Trends Food Sci. Technol. 1999: 10 107-10) .
[0029] The term "non-replicating" used in the context of the present invention means that no viable cells and / or colony forming units can be detected by classical plating methods. Such classical plating methods are summarized in the microbiology book: James Monroe Jay, Martin J. Loessner, David A. Golden. 2005. Modern food microbiology. 7th edition, Springer Science, New York, N. Y. 790 p. Typically, the absence of viable cells can be shown as follows: no visible colony on agar plates or no increasing turbidity in liquid growth medium after inoculation with different concentrations of bacterial preparations ('non replicating'samples) and incubation under appropriate conditions (aerobic and / or anaerobic atmosphere for at least 24h) .
[0030] Various preferred features and embodiments of the present invention will now be described by way of non-limiting examples. The skilled person will understand that they can combine all features of the invention disclosed herein without departing from the scope of the invention as disclosed.
[0031] Any reference to prior art documents in this specification is not to be considered an admission that such prior art is widely known or forms part of the common general knowledge in the field. All publications mentioned in the specification are herein incorporated by reference.
[0032] As used in this specification, the words “comprises” , “comprising” , and similar words, are not to be interpreted in an exclusive or exhaustive sense. In other words, they are intended to mean “including, but not limited to” . The terms “comprises” , “comprising” , and similar words also include the term “consisting of” .
[0033] The practice of the present invention will employ, unless otherwise indicated, conventional techniques which are within the capabilities of one of ordinary skill in the art. Such techniques are explained in the literature. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.
[0034] Numeric ranges are inclusive of the numbers defining the range and all percentages disclosed herein are on a w / w basis, unless stated otherwise. Where components of the infant cereal product are given a wt. %value on a dry weight basis, these are relative to the dry weight of the infant cereal product, i.e. not taking into account any water or moisture that may be present in the product.
[0035] As used herein the term “about” means approximately, in the region of, roughly, or around. When the term “about” is used in conjunction with a numerical value or range, it modifies that value or range by extending the boundaries above and below the numerical value (s) set forth. In general, the terms “about” and “approximately” are used herein to modify a numerical value (s) above and below the stated value (s) by 10%.
[0036] Hydrolysed milk protein source
[0037] The infant cereal product according to the invention contains a hydrolysed milk protein source.
[0038] Without being bound by theory, it is thought that through using a hydrolysed milk protein in the infant cereal product, the antigenicity of the cereal product will be reduced compared to an equivalent non-hydrolysed protein source. As a result, it is believed that the infant cereal product will be less likely to cause symptoms in infants having a milk allergy. It is also thought that such an infant cereal product will help promote tolerance to milk proteins in infants.
[0039] Milk protein sources based on, for example, whey, casein and mixtures thereof may be used. The hydrolysed milk protein source is preferably a partially hydrolysed milk protein source. The partially hydrolysed milk protein source may comprise partially hydrolysed whey protein, partially hydrolysed casein protein, or a mixture thereof. In a particularly preferred embodiment, the partially hydrolysed milk protein source is partially hydrolysed whey protein.
[0040] As far as whey proteins are concerned, the protein source may be based on acid whey or sweet whey or mixtures thereof and may include alpha-lactalbumin and beta-lactoglobulin in any desired proportions. In some embodiments the protein source is whey predominant (i.e. more than 50%of proteins are coming from whey proteins, such as more than 60%or more than 70%) .
[0041] The proteins may be either fully or partially hydrolysed. If hydrolysed proteins are required, the hydrolysis process may be carried out as desired and as is known in the art. Hydrolysis of proteins is commonly known and can be done by many different methods, for example by enzymatic hydrolysis by using an enzyme such as pancreatic protease to stimulate the naturally occurring hydrolytic process. Hydrolysis may also be by prolonged boiling in a strong acid or a strong base. In the context of the present invention, the partially hydrolysed protein may be produced by any suitable method known in the art. For example, a whey protein hydrolysate may be prepared by enzymatically hydrolyse the whey fraction in two steps as described in EP 0322589 A1. For extensively hydrolysing protein, the whey protein may be subjected to triple hydrolysis using first the enzyme Alcalase 2.4 L (EC 940459) , then Neutrase 0.5L and then pancreatic protease at temperatures about 55℃.
[0042] If the whey fraction used as the starting material is substantially lactose free, it is found that the protein suffers much less lysine blockage during the hydrolysis process. This enables the extent of lysine blockage to be reduced from about 15%by weight of total lysine to less than about 10%by weight of lysine; for example about 7%by weight of lysine which greatly improves the nutritional quality of the protein source.
[0043] The proteins of the milk protein source may be fully hydrolysed or partially hydrolysed. Preferably, the milk protein source is partially hydrolysed. In particular, the degree of hydrolysis (DH) of the protein can be between about 2%and about 80%, preferably between about 8%and about 60%, more preferably between about 10%and 40%, even more preferably between about 15%and 25%. It is particularly preferred that the degree of hydrolysis be between 15%and 21%.
[0044] Without being bound by theory, it is thought that the degree of hydrolysis of the milk protein source may affect the antigenicity of the protein source as well its ability to induce tolerance to cows’ milk proteins. Preferably, the partially hydrolysed milk protein has a residual allergenicity at least 100 times less than that of the intact (i.e. non-hydrolysed) protein. The residual allergenicity of the partially hydrolysed milk protein may be measured by the technique described by Fritsche et al (Int. Arch. Aller and Appl Imm., 93, 289-293, 1990) . Such a partially hydrolysed milk protein and products containing it may be described as hypoallergenic in accordance with the provisions of EU Directive 96 / 4 / EC.
[0045] In an embodiment of the invention, the infant cereal product may comprise both a partially hydrolysed milk protein source and another protein source which comprises intact protein. For example, the source of protein may comprise both intact protein and partially hydrolysed proteins, such as a for example a whey protein isolate. Further, the composition or infant formula according to the present invention may comprise a partially hydrolysed protein hydrolysate and another protein source, said other protein source comprising intact protein. For example, partially hydrolysed whey protein isolate and skim milk protein.
[0046] The infant cereal product may comprise between about 1 wt. %and about 20 wt. %, preferably between about 5 wt. %and about 15 wt. %, more preferably between about 5 wt. %and about 10 wt. %, and most preferably about 7.6 wt. %of the hydrolysed milk protein source on a dry weight basis.

[0065] The infant cereal product may also comprise one or more probiotic microorganisms. Such probiotic organisms may help maintain healthy digestive tract flora in the infant, support the infant’s immune system, and generally support healthy growth and development.
[0066] In preferred embodiment one or more probiotic microorganisms are selected from the group consisting of of bifidobacteria, lactobacilli, propionibacteria, or combinations thereof. Particular examples of suitable probiotic microorganisms are Bifidobacterium longum, Bifidobacterium lactis, Bifidobacterium animalis, Bifidobacterium breve, Bifidobacterium infantis, Bifidobacterium adolescentis, Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus paracasei, Lactobacillus salivarius, Lactobacillus reuteri, Lactobacillus rhamnosus, Lactobacillus johnsonii, Lactobacillus plantarum, Lactobacillus fermentum, Lactococcus lactis, Streptococcus thermophilus, Lactococcus lactis, Lactococcus diacetylactis, Lactococcus cremoris, Lactobacillus bulgaricus, Lactobacillus helveticus, Lactobacillus delbrueckii, Escherichia coli and / or mixtures thereof.
[0067] In a particularly preferred embodiment, the infant cereal product comprises Bifidobacterium lactis. Bifidobacterium lactis HN019 has been studied for a variety of traits important to its ability to function as a probiotic (see e.g. Sanders, M.E., 2006. Journal of clinical gastroenterology, 40 (9) , pp. 776-783) .

[0122] Preparation of compositions
[0123] The infant cereal product according to the present invention may be prepared by any known or otherwise suitable manner.
[0124] For example, the infant cereal product may be produced by blending together the carbohydrate source, the lipid source, and the hydrolysed milk protein source in appropriate proportions. Vitamins and minerals (and any other ingredients) may be added at this stage, but may also be added later to avoid thermal degradation.
[0125] Treatment and / or prevention of milk allergy
[0126] The infant cereal product of the invention may be used in the treatment and / or prevention of milk allergy in a subject. In one embodiment, the infant cereal products are for use in the prevention of milk allergy. In another embodiment, the infant cereal products are for use in the prevention of milk allergy.
[0127] Preferably, the infant cereal products of the invention are for use in the treatment and / or prevention of cows’ milk allergy. Cow's milk protein (CMP) is the leading cause of food allergy in infants, affecting 2-3%children worldwide. Most children with CMP-allergy (CMPA) have two or more symptoms: 50-70%have skin symptoms, 50-60%have gastrointestinal symptoms, and 20-30%have airway symptoms. Severe and life-threatening symptoms may occur in 10%of children. (Nutten, 2018. EMJ Allergy lmmunol, 3 (1) , pp. 50-59) .
[0128] Skin symptoms can include urticaria, atopic eczema, and angioedema. Gastrointestinal symptoms can include dysphagia, frequent regurgitation, colic, abdominal pain, vomiting, anorexia, refusal to feed, diarrhea (with or without intestinal protein or blood loss) , constipation (with or without perianal rash) , failure to thrive, occult blood loss, and iron-deficiency anemia. Respiratory symptoms can include runny nose, wheezing, and chronic coughing. Other general symptoms include anaphylaxis and shock-like symptoms with severe metabolic acidosis, vomiting and diarrhea (food protein-induced enterocolitis syndrome) . These symptoms are typically unrelated to infections, drug intake, or other causes (Koletzko, S., et al., 2012. Journal of pediatric gastroenterology and nutrition, 55 (2) , pp. 221-229) .
[0129] As discussed above, it is believed that the infant cereal product of the invention comprising at least partially hydrolysed milk protein is both: (a) suitable for ingestion in a subject having a milk allergy; and (b) suitable for promoting the tolerance of milk proteins in a subject, thereby aiding in the prevention of a milk allergy in the subject.
[0130] The subject may be any suitable subject. Suitably, the subject may be a human. In preferred embodiments, the subject is an infant, a toddler, or a young child. The term “infant” may refer to a subject aged from about 6 months to about 1 year. The term “toddler” may refer to a subject aged from about 1 year to about 3 years. The term “young child” may refer to a subject aged from about 3 years to about 10 years, from about 3 years to about 9 years, from about 3 years to about 8 years, from about 3 years to about 7 years, from about 3 years to about 6 years, or from about 3 years to about 5 years. The subject is preferably an infant or toddler of at least 6 months of age.
[0131] In preferred embodiments, the subject is at heightened risk of a milk allergy. This is the case where, for example, other family members of the subject have food allergies or other allergic diseases.
