摘 要：
以莲原花青素低聚体(lotus oligomeric proantho cyanidins,LSOPC)为添加物,研究其在菜籽油中的抗氧化作用。结果表明:0.02%的原花青素低聚体在油脂中的抗氧化性相当于0.02%的2,6-二叔丁基-4-甲基苯酚(butylated hydroxytoluene,BHT),其含量增至0.10%时,在油脂中的抗氧化性仍明显小于0.02%叔丁基对苯二酚(tertiary butylhydroquinone,TBHQ);油脂在氧化过程中,酸价从0.99升至1.19;类胡萝卜素含量(β-胡萝卜素当量)从48.4μg/g降至0.99μg/g;油脂的白度由24.50升至26.82;油酸、亚油酸和亚麻酸含量的变化最为明显,分别从50.78×104、15.60×104、5.71×104 mg/kg降至44.54×104、13.39×104、4.49×104 mg/kg。

摘 要：
The ability of oligomeric procyanidins from lotus seedpod(LSOPC)to inhibit oxidation in bulk rapeseed oil was studied.The results showed that 0.02% LSOPC was equal to 0.02% BHT in inhibiting the oxidation of rapeseed oil.However,0.10% LSOPC was less than 0.02% TBHQ.The acid value varied from 0.99 to 1.19,and the carotenoid content(β-carotene equivalent)reduced from 48.4μg/g to 0.99μg/g.The white index(WI)of oil increased by 24.50 reaching upto 26.82.Oleic acid,linoleic acid and lenolenic acid were significantly changed from 50.78×104 mg/kg,15.60×104 mg/kg and5.71×104 mg/kg to 44.54×104 mg/kg,13.39×104 mg/kg and 4.49×104 mg/kg,respectively.
