Bulletin of the IDF N° 504/2020: New applications of MIR spectrometry: Quality assurance practices with new parameters in raw milk analysis
Mid InfraRed (MIR) spectrometry is traditionally applied for quantitative determination of major components of milk such as fat, protein or lactose. For these “traditional” parameters, MIR Filter apparatus techniques have been used for a long time. This document focuses on the required checks with the implementation of new quantitative applications and how the quality assurance of the results can be assured. New approaches are presented.

Traditionally applied for quantitative determination of major components of milk, MIR Filter apparatus techniques have been used for a long time. Recently, Fourier-transform infrared spectroscopy (FTIR) collects high-spectral-resolution data over a wide spectral range. Thanks to additional prediction models developed by researchers and instrument manufacturers, FT-IR spectra can be used beyond quantitative determination of major components of milk such as fat, protein or lactose, to measure other dairy components such as fatty acids and minerals, and also to measure qualitative parameters. However, traditional calibration procedures developed with filter apparatus need to be adapted to respond to the more complex models used.
