Název v původním jazyce

Application of FT Near Spectroscopy for Determination of True Protein and Casein in Milk.

Popis výsledku v původním jazyce

Our work deals with a possibility of determination of true protein and casein in cow's, ewe's and goat's milk and in ewe's colostrums by FT NIR spectroscopy. Samples of milk were analysed by FT NIR in reflectance mode with the transflectance cuvette. Thevalues of correlation coefficient of calibration were as follows: cow's protein 0.943; cow's casein 0.964; ewe's protein 0.997; ewe's casein 0.977; goat's protein 0.989; goat's casein 0.890; ewe's colostrums protein 0.983. Calibration was tested using the same set samples by cross validation method. The values of correlation coefficient of validation were as follows: cow's protein 0.923; cow's casein 0.910; ewe's protein 0.994; ewe's casein 0.963; goat's protein 0.972; goat's casein 0.814; ewe's colostrums protein 0.871. NIRs results were compared with reference data and no significant differences between them were found (P = 0.05). Results of this study indicate that FT NIR spectroscopy can be used for a rapid analysis of protein and
