Advanced Instruments, part of John Morris Scientific, exhibited a three-minute fluorometric test method for assessing the pasteurisation of milk at the Worldwide Food Expo 2009.
The Fluorophos Test System offers a rapid, sensitive fluorometric method that delivers accuracy over a range of ALP levels, including low values, for milk from cows (whole, semi-skimmed, skimmed and flavoured) as well as from sheep, water buffalo and goats.
Benefits include high precision, reproducibility and high sensitivity, according to the company.
In May 2007, the European Union (EU) adopted the fluorometric method (ISO Standard 11816-1) as the new standard in assessing the correct pasteurisation of milk.
The system has also been approved as a full international standard method by the International Dairy Federation (IDF 155), the International Standards Organization (ISO 11816) and the CEN European Standards Organization.
It is also approved by the US Food and Drug Administration (FDA), the US Interstate Milk Shippers and AOAC International.
Also showcased at the event, the 4250 Single-Sample Cryoscope uses the freezing-point method to precisely determine added water in milk.
The 4250 provides onboard sample identification and accurate results in either timed plateau or plateau-seeking mode.
Advanced Instruments also exhibited Cryoline consumable supplies, which have been designed specifically to achieve accurate results from freezing-point cryoscopes.
Cryoline products are designed to ensure the quality of sample results while meeting or exceeding ISO, HACCP and QA/QC requirements.
These supplies are claimed to provide traceable materials for use with milk and dairy products, offering stable results and the monitoring and control of milk supply process and product integrity, from farm to finished product.
