标准范围

ISO/TS 6090 | IDF/RM 82:2004规定了检测牛奶和奶粉、酪乳和酪乳粉以及乳清和乳清粉中磷酸酶活性的筛选方法。给出了两种备选程序（A和B）。程序A比较简单，因为它不包括澄清处理，特别适合牛奶。程序B包括澄清步骤，该步骤允许更灵敏的检测，如果需要，通过该步骤可以获得更好的定量结果。如果使用任何一种方法来检查这些产品或其原材料的适当巴氏杀菌，则需要进行进一步测试，以确保磷酸酶活性不是由热稳定微生物磷酸酶或重新激活的磷酸酶引起的。

ISO/TS 6090|IDF/RM 82:2004 specifies a screening method for the detection of the phosphatase activity in cow's milk and dried milk, buttermilk and buttermilk powder, and whey and whey powder.Two alternative procedures (A and B) are given. Procedure A is the simpler as it does not include a clarification treatment and is especially suited for milk. Procedure B includes a clarification step which allows a more sensitive detection through which better quantitative results can be obtained, if desired.If either method is used for checking the proper pasteurization of these products or their raw materials, then further tests are necessary to ensure that the phosphatase activity is not due to either heat-stable microbial phosphatase or reactivated phosphatase.
