phosphatase test

phosphatase test A test for the adequacy of pasteurization of milk. The enzyme phosphatase, normally present in milk, is denatured at a temperature slightly greater than that required to destroy the tubercle bacillus and other pathogens; therefore the presence of detectable phosphatase activity indicates inadequate pasteurization. The test can detect 0.2% raw milk in pasteurized milk.
