Preparation method for microencapsulation whey protein hydrolysate with prebiotics and whey protein concentrate being wall materials

Abstract

The invention discloses a preparation method for microencapsulation whey protein hydrolysate with prebiotics and whey protein concentrate being wall materials. According to the method, the microencapsulation whey protein hydrolysate is prepared with the whey protein concentrate and the prebiotics being the wall materials, and whey protein hydrolysate being a core material, wherein the prebiotics are fructo-oligosaccharide or galacto-oligosaccharide or a mixture of fructo-oligosaccharide and galacto-oligosaccharide, and the whey protein hydrolysate is obtained by hydrolyzing the whey protein concentrate through protease. The problems that whey protein hydrolysate has a severe bitter taste and is high in moisture absorption are successfully resolved. The whey protein concentrate and the prebiotics are the effective wall materials of the microencapsulation whey protein hydrolysate which can be directly eaten as functional food. Serving as a basic ingredient, the microencapsulation whey protein hydrolysate is particularly suitable for being directly added into infant formula to produce infant formula with partial hydrolysis whey protein, and because the wall materials and the core material in use are basic materials used for the infant formula, and no other components are introduced, safety is high; or the microencapsulation whey protein hydrolysate serves as the basic material of other functional food. The whey protein concentrate and the prebiotics serve as the wall materials and have the advantages of being high in nutritive value and improving intestinal florae.

Description

technical field [0001] The invention belongs to the technical field of microcapsules, and specifically utilizes whey protein concentrate and prebiotics (fructo-oligosaccharides, galacto-oligosaccharides, a mixture of fructo-oligosaccharides and galacto-oligosaccharides) as wall materials, and whey protein hydrolyzate Prepare microcapsules for the core material. Background technique [0002] At present, moderately hydrolyzed whey protein hydrolyzate (mainly whey protein hydrolyzed peptide) has been applied in infant formula milk powder. One of the functions is that whey protein hydrolyzate has the advantages of easy absorption compared with protein; the second is Because whey protein is allergic, and infants and young children are susceptible to allergies caused by whey protein, the whey protein hydrolyzate obtained by enzymatic hydrolysis of whey protein has low allergenicity. However, when it is used as an ingredient in infant food and other functional foods, whey protein ...

AI Technical Summary

Problems solved by technology

However, when it is used as an ingredient in infant food and other functional foods, whey protein hydrolyzate has problems such as bitterness, easy moisture absorption, etc., and may react with other ingredients in functional foods, resulting in low bioacceptability and unsuitable Occurrence of phenomena such as stability, thus limiting its application in functional foods

[0003] The methods of reducing bitterness mainly include using activated carbon to absorb bitter peptides, chromatography to remove bitter peptides, and using ethanol to selectively adsorb bitter peptides. Although these methods can play a role in weakening bitterness, these methods will lead to partial whey Loss of protein hydrolyzate, resulting in increased production costs
