INVESTIGATION ON ANTIOXIDANT ACTIVITY OF DIFFERENT VARIETIES OF APPLES

Abstract
The article presents the results of the spectrophotometric experimental investigation on antioxidant activity with FRAP (ferric reducing ability of plasma) and FIC (ferrous-ion chelating) and phosphomolybdate methods in the apple juice and pulp of three summer varieties («Konfetnoe», «Malt», «Montet»), three autumn varieties of the Volga region («Spartak», «Kuibyshevskoe», «Jigulevka») and apple aseptic concentrates produced from summer and autumn varieties.
Keywords
Apples, apple concentrate, antioxidant, summer variety, autumn variety, FRAP, chelating activity, phosphomolybdate method
