Comparison of an analytical techniques for determination of an antioxidant activity in food
 Křenová, Alena ; Vespalcová, Milena (referee) ; Diviš, Pavel (advisor)
This bachelor‘s thesis deals with the characterization of natural and synthetic antioxidants and their effects on free radicals. Natural antioxidants are usually absorbed as a part of complex mixtures and that’s why we try to characterize an antioxidant activity as a whole. Chemical and physical methods have been developed to determine the total antioxidant activity of food. This thesis focuses on chemical methods, specifically on ABTS and DPPH, which are based on a reaction of antioxidants with synthetic radicals. Next chemical method is FRAP, which is based on the reducing ability of antioxidants. In the experimental part, these methods are compared from a perspective of their performance and the results of the analysis of real food samples.
