The Comparative Evaluation of Fermented and Non-fermented Soybean Extract on Antioxidation and Whitening

摘要

The present study was performed to compare the antioxidative and whitening activities of fermented soybean extract (FSB) and non-fermented soybean extract (SB). Antioxidative and whitening activities of FSB and SB were evaluated by the determination of DPPH, superoxide radical and hydroxyl radical scavenging activities, linoleic acid inhibition activity, and tyrosinase inhibition activity. FSB showed the higher effect than SB in the antioxidative activities. Also FSB showed the better effect than SB in whitening activity. These results demonstrated that the fermentation played a more excellent role than the non-fermentation in antioxidation and whitening. Therefore, this study suggested that FSB could be a useful cosmetic ingredient for antioxidation and skin whitening.
