Phosphatase test of milk

WebTo quickly verify that HTST dairy products are fully pasteurized, the Charm F-AP and PASLite tests detect the widely-accepted chemical marker alkaline phosphatase. Both tests are US FDA approved and detect down to 20 milliunits per liter (mU/L) of phosphatase—well below the 350 mU/L (0.1% raw milk) level required by most governments. WebMilk is routinely tested for proper pasteurization. The Scharer and Fluorophos methods, among others, test for residual alkaline phosphatase (ALP) activity to assure proper pasteurization. Until recently there were no tests available to accurately detect residual ALP activity levels below the U.S. l …
