浓香和精炼葵花籽油加速氧化过程中 综合品质变化的差异Differences in comprehensive quality changes between fragrant and refined sunflower seed oils in the accelerated oxidation process
对浓香葵花籽油、精炼葵花籽油及其分别添加抗氧化剂叔丁基对苯二酚(TBHQ)的葵花籽油进行Schaal烘箱法加速氧化试验,通过考察加速氧化期间4个葵花籽油样过氧化值、酸值、维生素E含量、甾醇含量及挥发性风味成分含量的变化,对比分析两种葵花籽油氧化稳定性、预测货架期、营养成分和挥发性风味成分含量变化的差异,以及TBHQ对两种葵花籽油氧化稳定性及其他综合品质影响的差异。结果表明:若以过氧化值达到相应葵花籽油国标限值作为评价指标,空白及添加TBHQ的浓香葵花籽油、空白及添加TBHQ的精炼葵花籽油的预测货架期分别为64、272、48、96 d;经21 d的加速氧化,上述4种葵花籽油中维生素E损失率分别为...
