NIR spectroscopy for foodstuff monitoring

Purpose – To review the use of near‐infrared (NIR) spectroscopy in the process control of foodstuffs.Design/methodology/approach – Presents two spectroscopy products used in the production environment: a single‐board system aimed at OEMs, and a complete fibre‐optic spectrometer ready for the end‐user. Gives examples of applications within the food and drink industry.Findings – Finds that these instruments are fast, effective and inexpensive, and rugged enough for the processing environment.Originality/value – Draws attention to the potential of NIR spectroscopy outside the confines of the laboratory.
