The Advanced Instruments Fluorophos ALP Test System takes the phosphatase test for pasteurization verification to its highest level by yielding quantitative results. The Alkaline Phosphatase (ALP) enzyme found naturally in raw milk is inactivated at slightly higher temperature and time conditions than those required to kill milk-born pathogens. The Fluorophos Assay detects the amount of ALP left after pasteurization If the pasteurize deteriorates, fails or for some other reason raw milk enters pasteurized milk, the Fluorophos Assay will detect a contamination of as little as 0.003% raw milk about 30 times lower than the old technology.
The Fluorophos ALP Test is the EU reference test and has been approved by the International Standards Organisation (ISO11816-1), IDF, Interstate Milk Shippers and AOAC. It is more sensitive, quicker and reproducible than older methods. The Fluorophos test is based on the same chemistry used in traditional colorimetric tests for pasteurization verification, but involves the liberation of a chemical measured by fluorescence rather than interpretation of colour, improving accuracy and dramatically reducing the evaluation process from 90 to 3 minutes.
The high sensitivity of the Fluorophos Assay allows trends in pasteurize performance to be monitored. A gradual deterioration can be identified and rectified well in advance of a legal failure. The Fluorophos ALP Test System is easy to operate and uses the same method for semi-skim, skim, whole, flavoured milks and raw creams.
