Abstract

This study was carried out to investigate the antioxidant effects of melanin extracts, including silkie fowl skin melanin (SS-melanin), silkie fowl comb melanin (SC-melanin), sepia ink sac melanin (SE-melanin), octopus ink sac melanin (OC-melanin) and synthetic melanin (SY-melanin).The results showed that with the addition of melanin extracts, linoleic acid peroxide significantly, decreased (p<0.05) with the increase in the irradiative time of UV and that OC-melanin had the highest efficiency on antioxidant activity (p<0.05).Melanin extract had reducing power and chelating power to Fe 2+ , which increased with the increase in the different melanin concentration.Therefore, it could be concluded that the antioxidant action of melanin extracts did not come from one single function, but is a result of many characteristic functions.(Asian-Aust.
