NIRmilk

Near infra red light (NIR) measurements are made at 152 wavelengths on 17 milk samples. While milk runs through a glass tube, infra red light is sent through the tube and the amount of light passing though the tube is measured at different wavelengths. Each milk sample was additionally analysed for fat, lactose, protein and dry matter.
