Тезис 

ISO 11816-2|IDF 155-2:2003 specifies a fluorometric method for the determination of alkaline phosphatase activity in cheese.

This method is also applicable to soft cheeses and semi-hard cheeses for distinguishing raw milk cheeses from cheese produced with pasteurized milk, provided that the mould is only on the surface and not also in the inner part (e.g. blue-veined cheeses). This method can also be used to check the proper pasteurization of cheese or its raw material.

In large hard cheeses where the whey curd mixture is scalded at temperatures above 50 degrees Celsius, high temperatures remain for a relatively long time. This is especially the case in the centre of these cheeses, thus promoting phosphatase inactivation. To distinguish, therefore, between hard cheeses from raw milk and hard cheeses from pasteurized milk is difficult and often even impossible by this method.
