Research Progress in the Effect of Glycosylation on Functional Properties and Allergenicity of Dairy Products

In recent years, milk allergy has attracted more and more attention because of its increasing incidence and in-depth research on it. The glycosylation modification of milk proteins not only can improve the functional properties of dairy products, but also reduce the allergenicity of dairy products by destroying or shielding the epitope of allergen proteins. This modification has found applications in various fields such as food flavor, antioxidants and carriers. This paper introduces common glycosylation reactions in the dairy industry, discusses their advantages and disadvantages and the pattern of changes in functional properties and allergenicity of milk proteins after glycosylation, and summarizes the methods to avoid the negative effects of glycosylation reactions. This review provides a reference for the research, development and application of glycosylation modification in milk allergy and dairy processing.
