摘  要:
目的:以混合菌种发酵法制备的花红可溶性膳食纤维(MPSDF)为原料,研究其对.OH、O-2.和DPPH自由基3种自由基的清除作用,以及对大豆油的抗氧化效果。方法:采用.OH、O-2.体系、DPPH自由基体系和油脂过氧化值测定法,测定MPSDF对.OH、O-2.和DPPH自由基的清除率以及Schaal烘箱法对大豆油过氧化值抑制效果。结果:MPSDF对.OH和O-2.均有较强的清除能力,其EC50分别为4.63mg/mL和8.84mg/mL,但对DPPH自由基的清除率较低。MPSDF添加到大豆油中,其抗氧化效果与丁基羟基茴香醚(BHA)接近。结论:发酵法制备的花红可溶性膳食纤维(MPSDF)对.OH和O-2.均有较强的清除作用,对大豆油有很强的抗氧化作用,具有较强的抗氧化活性。

摘  要:
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.
