Production of sesaminol and antioxidative activity of fermented sesame with P8, ATCC 4356, S10.

This study was carried out to select the most competent bacterial cultures that could convert sesaminol glycosides to aglycone by β-glucosidase produced by lactic acid bacteria such as (LP), and in sesame fermented at 37°C for 24 h. The pH of fermented sesame was decreased compared to non-fermented controls. The pH of LP was lower than that of the other two during fermentation. Fermented sesame had higher antioxidant activity compared to non-fermented controls during the entire fermentation time. Total phenol content, DPPH free radical scavenging assay, reducing power assay of sesame fermented by LP was the highest compared to the others. In addition, sesame fermented by LP had more bioconversion of sesaminol glycoside to aglycone compared to the others. Therefore, LP was the best bacterial culture of the three strains studied for producing functional fermented sesame for good health.
