摘要: 酸奶的生产主要以鲜奶、奶粉、乳清浓缩蛋白(WPC)等乳成分为主要原料,原料的选择直接影响到酸奶的品质。本文对乳清浓缩蛋白(WPC-80和WPC-34)代替部分全脂奶粉和脱脂奶粉生产酸奶时,对产品的保水性、粘度、口感及组织状态进行了比较分析。结果表明WPC-80和WPC-34代替10%~20%全脂奶粉和脱脂奶粉生产酸奶时,可改善酸奶的品质,提高酸奶的保水性。

Abstract: The paper studied and compared water holding capacity, viscosity,flavor and texture of yoghurt, when the yought was produced by whey protein concentrate(WPC-80 and WPC-34)and milk powder. The results showed that the water holding capacity, viscosity,flavor and texture of the yought produced by 10%~20% WPC(WPC-80 or WPC-34)plus 80%~90% milk powder was better than that produced by 100% milk powder alone.
