Evaluation of total phenolics content and antioxidant activity of Mongolian domestic and imported beers

Popis výsledku v původním jazyce

The antioxidant activity and total phenolics content of 6 domestic and 4 imported beers in Mongolian markets were evaluated. The content of antioxidant activity was determined as gallic acid equivalents by l,l-phenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, which is based on the ability of a sample to change organic free radicals. The content of total phenolic compounds was determined as gallic acid equivalents by a spectrophotometric Folin-Ciocalteu method. Total antioxidant activity variedfrom 0.23 to 0.38 mmol GAE/L, and total phenolic content ranged from 88 ? 2.38 to 204 ? 3.50 mg GAE /L in ?Hite lager" and ?Budweiser dark" beers, respectively. ?Kharkhorin? and ?Jalam khar? beers also had relatively higher TPC (> 150 mg GAE/L). A linear positive relationship existed between the antioxidant activity and total phenolic acids content of the tested commercial beers (R2 0.73). This result suggests that 73% of the antioxidant capacity of commercial beers accessions results f
