A new software functionality supporting adulteration testing is available on specific models of MilkoScan analysers from FOSS .
FOSS has supported adulteration testing for a number of years through a software functionality for the MilkoScan FT 120 analyser and the functionality was subsequently extended to certain other MilkoScan analysers.
The new functionality called the abnormality spectrum screening module (ASM) is receiving considerable interest from the milk-testing community.
Testing for abnormalities with the ASM was covered extensively at the recent IDF World Dairy Summit 2010 with two presentations exploring its use.
Christophe Cavin, Nestlé presented on ‘Strategies for the prevention of milk adulteration’ while Steve Holroyd, Fonterra and Per W. Hansen from FOSS explored the use of FTIR technology for routine milk screening.
The ASM software functionality is available for MilkoScan analysers using Fourier Transform Infrared (FTIR) technology.
Users must first define a normal grouping of milk samples for their calibration with FOSS developing a software application that helps to select samples.
The tool will be available in 2011 together with a protocol for getting started.
Screening as part of routine operations
Raw milk containing abnormalities is a growing problem and can be caused by acts of deliberate adulteration or by accidents.
MilkoScan instruments are already used around the world to check raw milk for payment and quality assurance purposes.
The ability to program raw milk 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.
