The aim of this work was to investigate the antioxidant activity of Caciocavallo cheese made from the milk of 2 breeds, Italian Brown and Italian Holstein, and ripened for 1, 30, 60, 90, and 150 d. The antioxidant activity of cheese was measured using the 2,2’-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS), ferric-reducing antioxidant power (FRAP), and thiol assays. Statistical analysis showed a significant effect of the studied factors. Italian Brown cheese had higher antioxidant activity than Italian Holstein cheese, and antioxidant activity increased during ripening of both cheeses types. Moreover, antioxidant activity varied during ripening depending on the rate of formation of soluble peptides. To date, few studies have evaluated the effect of genetic type on antioxidant capacity of the pasta filata cheeses; thus, this study forms the basis of new knowledge that could lead to the production of a pasta filata cheese with specific nutraceutical characteristics.
