A study was undertaken to determine the feasibility of building a system capable of measuring the protein and fat content in dairy based samples. The system would be based upon a micro-spectrometer. Using Beers-Lambert law, spectral absorption changes due to protein and fat variation in dairy samples are obtained, over the spectral region 800 to 1100 nm. Samples representing a range of liquid milk products, manufactured in the dairy industry were fabricated. These samples spanned typical fat
more &raquo; ... protein ranges. Each sample after preparation, was chemically analysed using standard Mojennier and Kjeldahl tests, for fat and protein content. The optical set-up required to optimise the collection from the sample is discussed. q 1999 Elsevier Science S.A. All rights reserved.
