花红可溶性膳食纤维的抗氧化活性
Antioxidant Activity of Soluble Dietary Fiber from Crab Apple Pomace
摘要
Abstract
Objective： To explore the antioxidant activity of soluble dietary fiber（SDF） prepared by fermenting crab apple（Malus asiatica） pomace with mixed strains.Methods： The scavenging rates of SDF derived from crab apple pomace against hydroxyl,superoxide anion and DPPH radicals and its inhibitory effect against lipid peroxidation in soybean oil were evaluated.Results： The SDF revealed strong scavenging capacity against hydroxyl and superoxide anion free radicals with an EC50 of respectively 4.63 mg/mL and 8.84 mg/mL,but the scavenging capacity against DPPH free radicals was weaker.The antioxidant effect of the SDF on soybean oil was similar to that of BHA.Conclusion： SDF derived from crab apple pomace has a strong scavenging capacity agaisnt hydroxyl,superoxide anion free radicals and an obvious antioxidant effect on soybean oil.Therefore,it can be applied as a food antioxidant,which will have promising application prospects.关键词
