Diploma thesis deals with use of near-infrared spectroscopy to detect falsification of goat's cheese. The basic knowledge of goat's and cow's milk and requirements for milk during cheese production are summarized in the theoretical part. There is also described the cheese production and the following part is devoted to food falsification with describing falsification of milk products and the facilities of adulteration detection by optical methods. The remaining part deals with NIR spectroscopy as a suitable method for the verification of food authenticity. The practical part is focused on the use of NIR spectroscopy to detect the difference between cheese samples with different concentrations of cow's milk in goat's cheese and subsequent use of discriminant analysis for evaluation. The results showed that the method is suitable for detection of falsification of goat's cheese and that is why could be useful for rapid analysis in practice.
