Description

Infant formula of a kind of anti-albumen allergy and preparation method thereof
Technical field
The present invention relates to a kind of infant formula, especially a kind of infant formula of anti-albumen allergy.
Background technology
Milk protein is first part of food proteins of formula milk feeding infant picked-up normally, is also the food allergen of the most often being determined.The baby of milk protein irritated (cmpa) there will be the symptoms such as vomiting, chronic diarrhea, malabsorption and growth retardation conventionally.Milk protein allergy refers to the bad reaction to milk protein of a kind of IgE or non-IgE mediation, and within 2 years old, following baby's incidence is about 2%.If cmpa infant can not get correct diagnosis and treatment, the cmpa infant month more than 1/2 will develop into many food hypersenstivities, have a strong impact on the quality of life of infant and family thereof.Up to now, the absorption of strictly avoiding milk protein is the unique effective method for the treatment of cmpa.Therefore for infant and the early stage selecting properly muting sensitive of children formula, substitute original formulation, improve and promote the nutrition of cmpa infant and grow to seem particularly important.
Present stage, the treatment of milk protein allergy is different according to irritated situation, has beans based formulas milk, depth hydrolysis's formula milk and three kinds of formulas of amino acid formula milk available.Bovine colostrum infant formula patent CN201010242738.0 has emphasized that the immunoglobulin (Ig) of colostrum own improves infant immunity effect, and has considered FOS and GOS gold combination performance prebiotic function, can not change the allergic phenomena of babymilk albumen; Breast base lactose free infant formula powder has solved diarrhoea and diarrhoea recovery problem that baby's lactose intolerance causes, but there is no to solve baby's albumen allergic problem at all.Therefore, albumen allergic problem is the subject matter of this type of children's allergy.Because the irritated infant of part milk protein simultaneously can be irritated to legumin, and legumin is low compared with the bioavilability of milk protein, long-term use may cause growth of weight not enough, and European paediatrics allergy and clinical immunology Hui Ji U.S. pediatric nutrition can not recommend beans based formulas to be applied to prevention and the treatment of the irritated infant of milk protein.The case that is in a bad way or can not makes a definite diagnosis, first-selected depth hydrolysis's formula milk or the treatment of amino acid formula milk.Most infants that suffer from milk protein allergy can tolerate depth hydrolysis's formula powder, if still have allergy sufferers can only select to using amino acid as the formula of nitrogenous source to depth hydrolysis's formula, account for make a definite diagnosis 10%, show as serious enteropathy or multiple food hypersenstivity more.Therefore amino acid formula is as serious systemic anaphylaxis, the serious concurrent Hypoproteinemia of enteropathy or poor growth baby's first-selection formula.But pure amino acid formula powder is expensive, and mouthfeel is poor, and has avoided anaphylactogen completely, can not progressively tolerate, therefore can not be as primary prevention.Depth hydrolysis's protein prescription powder, by special process technologies such as heating, hydrolysis, significantly reduced the antigenicity of protein component, and nutritive value is similar to ordinary powdered milk, thereby the most conventional.
Thereby the initial object of application protein hydrolysate formula is to reach the object that reduces milk protein allergy risk by the allergenicity reducing or eliminates milk protein.Protein through hydrolysis supervisor treated water solution protein prescription consists of small peptide or amino acid, in theory compared with intact proteins absorption more easy to digest.
Lactalbumin its antigenicity after being hydrolyzed significantly reduces, and partial function characteristic also improves simultaneously, as foaming characteristic, dissolubility and emulsibility and mouthfeel etc.But owing to making to be wrapped in the hydrophobic group that intramolecule is bitter taste in the meeting of hydrolyzed whey protein process, come out, the polypeptide that contains more hydrophobic grouping contacts with people's taste bud and just can make people produce bitter taste sensation, thereby limit it, in product, applies.For baby, molecular weight, lower than dipeptides, the tripeptides of 1000Da, is beneficial to and digests and assimilates most, and still, along with the increase of hydrolysis degree, bitter taste increases gradually.
Therefore, the lactalbumin hydrolysate of the high debitterize of exploitation degree of hydrolysis is also applied to formula powder and makes it have the irritated effect of effective anti-albumen, will have very important social value.
