摘要
乳清是工业生产干酪及干酪素的副产品。乳清的营养成分相当于除去酪蛋白的脱脂乳，约占牛乳营养成分的５５ ％ ，乳固体达６ ％ ～７ ％ ，其中粗蛋白１ ％ ，粗脂肪０ ．３ ％ ～０ ．４ ％ ，乳糖３ ％ ～５ ％ 。国外多利用乳清生产乳清粉和乳清蛋白浓缩物等。乳清饮料有３ 种形式：１） 乳清与果汁直接调配；２） 制做无蛋白澄清饮料；３） 发酵型乳清饮料。所以，乳清的合理开发利用十分重要。
Whey are by product of the industrial production of cheese and casein. The nutritive value of whey is equivalent to de-caseinated slimmed milk and holds 55% of the nutritive value of milk. Whey dry matter amounts to 6%～7%,1%coarse protein,0.3%～0.4% coarse fat,3%～5% lactose. For the most part, whey is processed into whey powder, and whey protein concentrate. Abroad, whey based drinks have three forms:1) whey directly mixed with fruit juice;2) clarified drinks having no protein;3) fermented drinks. So reasonable utilization of whey is of great importance to industry.
