本试验以酸值（AV）、过氧化值（POV）和丙二醛（MDA）含量作为评价指标，研究乙氧基喹啉、叔丁基羟基茴香醚（BHA）、二叔丁基羟基甲苯（BHT）三种抗氧化剂按不同组合或单体的形式添加到油脂中对米糠毛油抗氧化性能的影响。结果表明：与对照组相比添加不同抗氧化剂或抗氧化剂组合，米糠毛油AV无显著变化；POV随着时间延长不断提高，19 d后抗氧化剂添加组POV增速较对照组缓慢，且复合抗氧化剂抗氧化效果优于单体抗氧化剂。添加单体抗氧化剂后油脂MDA含量与对照组相比有所降低，复合抗氧化剂组MDA含量均低于单体组。结果提示，复合抗氧化剂的抗氧化效果优于单一抗氧化剂，单一抗氧化剂中以乙氧基喹啉效果最好，复合抗氧化剂则以0.15%乙氧基喹啉和0.015%BHA复配使用效果最好。

The trial was conducted to study the effects of several antioxidants on the antioxidation of crude rice bran oil.Using acid value (AV),peroxide value (POV)and malondialdehyde (MDA)as evaluation parameter,the effects of ethoxyquinoline,butylated hydroxytoluene (BHT),butyl hydroxy anisd (BHA) and complex of the antioxidants on the an-tioxidation of crude rice bran oil were studied under (37 ±1)℃ accelerated oxidation conditions.The results showed that:there were no significant differences in AV among all the groups.The POV increased slowly 19 days ago,but after that the POV increasing speed of antioxidants adding group was lower than that of control group,and the inhibitory effect of complex antioxidant was beffer than sing ones.The content of MDA in the groups with complex antioxidant were lower than that with single antioxidant.The results indicated that the effect of complex antioxidants were better than single antioxidant in improv-ing the antioxidative activity of crude rice bran oil.Among 4 kinds of complex antioxidants,the effect of 0.15%ethoxyquino-line+0.015%BHA was slightly better than the others,and the same as 0.3%ethoxyquinoline in 3 kinds of single antioxidants.
