New testing option extends scope of food safety screening

FOSS has extended the availability of software functionality that helps to spot adulterated raw milk.

The software allows MilkoScan™ analysers based on Fourier Transform Infrared (FTIR) technology to be programmed to give a warning of possible abnormalities in raw milk samples. MilkoScan instruments are already used around the world to check raw milk for payment and quality assurance purposes.

Raw milk containing abnormalities is a growing problem. The abnormalities can be caused by deliberate adulteration, for example, with lard or melamine or by accidents, for example, if milk from cows and buffalo are mixed.

Previously, the software functionality was only available for the FOSS MilkoScanFT 120 analyser.

It is now provided as part of the Foss Integrator software supporting FOSS dairy analytical solutions.

Screening to improve food safety

The ability to program analysers used in routine testing operations allows users to adopt a screening approach to incoming raw milk samples.

The programmed analyser does not identify specific contaminants, but helps to identify a suspect raw milk sample quickly and as a normal part of everyday testing. The suspect sample can then be further analysed to determine the contaminant.

The system works by monitoring the results of analysis performed using infrared spectroscopy. Looking at raw milk from a spectroscopic point of view, natural raw milk has a particular spectrum – a unique fingerprint. It is possible to program an infrared spectroscopy analyser to recognise the spectra (or fingerprint) representing normal milk. A warning is then given when samples do not match the fingerprint.

FOSS dairy market manager, Dorthe Bisgaard said: “The screening approach is a powerful tool in tackling milk adulteration, whether this occurs by accident or on purpose. With this screening option, quality assurance people can quickly check for many different types of adulteration and with no extra time or cost per routine test.”

About FOSS dairy solutions

For decades FOSS has helped dairies and milk testing laboratories to keep pace with their analysis demands. For instance, FOSS dedicated analytical solutions have proven significant for dairy-herd-improvement, raw milk testing, standardisation in dairy production and verification of end-product quality.

Today, trends such as increasingly sophisticated consumer tastes and the relentless pressure for profit improvement make FOSS dedicated analytical solutions more relevant than ever. They provide convenience, speed and labour savings, while delivering high analytical capacity and low cost per sample.

Solutions include compositional analysis, somatic cell count, hygienic quality of raw milk and compositional and microbiological testing of finished products such as cheese and yoghurt. Instruments are specifically designed for use in the laboratory, at the production line or for continuous process monitoring, for example, with some instruments available either as a laboratory model or as an at-line production model designed to withstand the production environments.
