摘要: 牛乳中的乳清蛋白主要包括β-乳球蛋白、α-乳白蛋白、牛血清白蛋白和免疫球蛋白。在牛乳加工过程中,热处理会使乳中乳清蛋白发生变性,影响了乳清蛋白的结构和活性,进而降低了牛乳的营养价值。本文对乳业发达国家液态乳的主要加工方式以及热处理过程对4 种乳清蛋白的影响进行了综述。

关键词: 乳清蛋白, 热处理, β-乳球蛋白, α-乳白蛋白

Abstract: β-Lactoglobulin, α-lactalbumin, bovine serum albumin and immunoglobulin constitute the major whey proteins in milk. Thermal treatment of milk causes denaturation of whey proteins, thereby affecting the structure and activity of whey proteins and reducing the nutritional value of milk. In this article, we review the major processing technologies for liquid milk used in different countries and the effects of thermal treatment of milk on the major whey proteins.

Key words: whey protein, thermal treatment, β-lactoglobulin, α-lactalbumin
