Correlation between Total Antioxidant Capacity and Polyphenols Content for some Beer Types

Monica Harmanescu, I. Gergen, H.D. Isengard
The aim of the present work was to determine the total antioxidant capacity and polyphenols content for 10 types of beer from Romanian market. Total antioxidant capacity was analyzed using two methods: FRAP and DPPH. Total polyphenols content was determinated using Folin Ciocalteu reagent. The highest FRAP and DPPH values were identified for Stejar type beer and the lower values for Bergenbier alcohol free beer. The polyphenols content is in good correlation with values obtained for total antioxidant capacity by FRAP and DPPH methods.
