常温奶和巴氏杀菌奶的营养价值有什么区别?

随着科技越来越发达,巴氏鲜奶现在受到广大消费者的喜爱,那么他和之前的常温奶有什么区别呢?

两者的区别在于,灭菌乳的微生物指标是很清晰的,达到商业无菌。而巴氏的微生物指标是允许有部分细菌存在,只是致病菌不得检测。菌落总度小于等于3万,大肠菌小于等于90个。由于国内原料乳在实际过程中污染比较高,企业一般采取高强度灭菌。

业内专家认为,两种方法对牛奶的营养成分破坏有没有差别,国内没有做过比对。但不可否认,由于营养素的破坏与温度和时间有关系,因此,短时超高温的灭菌乳虽然可以将细菌全数杀死,但是蛋白质在高温下易变性,水溶性维生素也容易被破坏,人体吸收蛋白质的效价会小于巴氏奶。
