Description
Near infra red light (NIR) measurments 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 drymatter.
