Objective: To evaluate the content of polyphenols and the antioxidant activity of cocoa products obtained under different processing conditions. Materials and methods: The samples were taken during the processing stages of the chocolate with sugar, chocolate with cloves and cinnamon, bitter chocolate and chocolate from cocoa powder and vegetable oil. The content of polyphenols was measured by the FolinCiocalteu’s method; the antioxidant activity was evaluated on the 2,2-Diphenyl-β-Picrylhydrazyl (DPPH) Radical and 2,2’-azino-bis-(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical. Additionally the ferric reducing ability was evaluated using FRAP’s method. Results: All the products studied showed significant differences in the total phenolic content and the antioxidant activity against various radical
