富勒烯C60作为油脂抗氧化剂的研究

摘要

The antioxidant effect of fullerene [C60] on oils was studied.The effects of fullerene [C60],tert-Butylhydroquinone (TBHQ),dibutyl hydroxyl toluene (BHT),propyl gallat (PG) and VE on peroxide values and protective factor PF20 of olive oil,Xanthoceras sorbifolia Bunge.oil,flaxseed oil and lard oil were studied through oven heating method,and heating experiments were carried out.The results showed that TBHQ had the best antioxidant effect on flaxseed oil and Xanthoceras sorbifolia Bunge.oil,followed by fullerene [C60],PG,BHT and VE.Fullerene [C60] had the best antioxidant effect on olive oil,followed by TBHQ,PG,BHT and VE.TBHQ had the best antioxidant effect on lard oil,followed by PG,BHT,fullerene [C60] and VE.In the heating experiments,there was no precipitate in the oils added with antioxidants and the color value did not change.Fullerene [C60] had good antioxidant property in oil,which could be used as oil antioxidant in food processing,production and storage.%研究富勒烯[C60]对油脂的抗氧化效果.通过烘箱加热法研究富勒烯[C60]与叔丁基对苯二酚(TBHQ)、二丁基羟基甲苯(BHT)、没食子酸丙酯(PG)、VE对橄榄油、文冠果油、亚麻籽油和猪油的过氧化值和防护因子PF20的影响并进行加热实验.结果表明,在亚麻籽油和文冠果油中的抗氧化效果为:TBHQ＞富勒烯[C60] ＞PG＞BHT＞VE;在橄榄油中的抗氧化效果为:富勒烯[C60]＞TBHQ＞ PG＞ BHT＞ VE;在猪油中的抗氧化效果为:TBHQ＞PG＞BHT＞富勒烯[C60]＞VE.在加热实验中,添加抗氧化剂的油脂均没有析出物且色值不发生变化.表明富勒烯[C60]在油脂中具有很好的抗氧化性能,可作为食品加工、生产与储存中油脂的抗氧化剂.
