花生四烯酸在乳制品中的应用

花生四烯酸(AA)是一种人体必需的多不饱和脂肪酸,是人体生长因子,影响婴幼儿大脑和神经发育.AA具有改善记忆力和视力、调节血脂和血糖、降低血清胆固醇、预防心血管疾病、辅助抑制肿瘤、预防癌变、神经功能调节等作用.人体自身不能合成AA,必需从食物补充才能满足机体代谢的需要,牛乳是人体补充营养物质的载体,而AA在牛乳中几乎不存在,所以在牛乳中强化AA已显得非常必要.本文介绍了AA添加带配方奶粉中的工艺流程和操作要点;AA应用于纯牛奶中的工艺流程和操作要点;开发富含AA酸牛奶的生产工艺和操作要点;开发富含AA乳饮料的工艺流程和操作要点.研究发现,AA在酸牛奶和乳饮料中的应用将是新的发展趋势,富含AA的乳制品将会给企业带来巨大的经济效益和社会效益.
