Past your eyes milk

Fourier transform near infrared (FT-NIR) spectroscopy can be used as a non-destructive test for the analysis of raw milk to ensure that it is still fresh. The degree of change in a given sample during storage depends primarily on the variables time and temperature. Now, collaborators from China and the USA have applied cheminformatics to FTNIR data to allow them to correlate that data with freshness and so provide the possibility of a simple and rapid inline test for checking the freshness of unpasteurized raw milk.
