Quick check for dairy pasteurisation effectiveness
Milk pasteurisation efficacy is typically monitored by checking for the presence of alkaline phosphatase (ALP) – an enzyme present in raw milk – thus ensuring a product is safe for consumption.

ALP is inactivated under high temperature/short time pasteurisation processes and is used as a marker of pasteurisation.

The new Hygiena ZymoSnap ALP pasteurisation verification device is said to help ensure that this test is both quick and easy to perform. Typical products that can be tested include milk, cream, flavoured milk and other milk-based products.

ZymoSnap measures ALP activity in milk products, delivering results in just five minutes to provide a low-cost alternative to conventional test methods.

Research in the US has shown that between 0.87% and 12.6% of raw milk samples are contaminated with pathogenic microorganisms.

According to Hygiena, reliance on monitoring pasteurisation time and temperature alone does not fully guarantee a safe product because it cannot detect cross-contamination events.
