The aim of the thesis was to find out whether NIR spectroscopy is a suitable method for adulteration control of cow and goat milk. Also to which concentration level the method is still effective was sought. Theoretical part summarizes information about the requirements for goat milk, its composition and processing possibilities. It also contains information about food adulteration and the relevant legislation. Infrared spectroscopy is theoretically described, particularly NIR spectroscopy. The experimental part describes the procedure of qualitative analysis using NIR spectroscopy, the method of evaluation and its results. Different samples of goat milk adulterated with various proportions of cow milk were compared. Results were evaluated using discriminant analysis. NIR spectroscopy has been demonstrated as a method suitable for detecting goat milk adulteration.
