Abstract: Hydrolyzed protein formula not only solves the problem of allergy or intolerance to cow’s milk proteins in infants and young children, but also meets the nutritional needs. Degree of hydrolysis is an important parameter to evaluate hydrolyzed protein formula. However, there are currently no methods available to determine the degree of hydrolysis of hydrolyzed protein formula. This article presents a brief introduction to the basic concepts of hydrolyzed protein formula and its degree of hydrolysis, and summarizes the existing methods for detecting the degree of hydrolysis of proteins. We expect this review to provide a reference for the establishment of detection methods for the degree of proteolysis of hydrolyzed protein formula.

Key words: hydrolyzed protein formula, degree of hydrolysis, detection methods, partially hydrolyzed protein formula, extensively hydrolyzed protein formula

摘要： 水解蛋白配方食品的研发解决了婴幼儿对牛乳蛋白过敏或不耐受问题的同时，满足了营养需求。水解度是水解蛋白配方乳粉的重要指标，但是目前国内外没有水解蛋白配方食品水解度的检测方法。本文简要介绍水解蛋白配方食品及水解度的基本概念，并深入讨论了现有的蛋白质水解度检测方法，以期为水解蛋白配方食品水解度检测方法的建立提供参考。
