Fig Vinegar as an Antioxidant and Antimicrobial Agent
Keywords:Fig vinegar, physicochemical, bioactivity, minimum inhibition concentration, Antimicrobial
AbstractFig vinegar is a special product which has a long history and is handed down from generation to generation. In the current study, characteristics of homemade fig vinegars supplied from different cities of Turkey were compared in terms of their physicochemical, antioxidant and antimicrobial properties. Physicochemical properties of the samples were very diverse. Total phenolic and flavonoid content, and ABTS+ and DPPH radical scavenging activities of the samples were ranged from 313.5 to 594.25 mg GAE/L and 42.52-132.42 mg catechin/L, and 0.44-3.98 Âµg TE/mL and 1.25-7.51 Âµg TE/mL, respectively. The antioxidant activity of vinegars is highly correlated with their phenolic and flavonoid contents. Furthermore, vinegar samples exhibited inhibitive effect on all test microorganisms and the minimum inhibition concentration values were ranged between 0.39 and 25% (v/v). These results indicated the distinct properties of homemade fig vinegars and the potential of them as antimicrobial and antioxidant substances.
