浓香菜籽油和精炼菜籽油氧化稳定性 及挥发性成分的差异Differences of oxidative stability and volatile components between fragrant and refined rapeseed oils

利用烘箱法加速氧化试验分析研究浓香菜籽油和精炼菜籽油氧化稳定性及挥发性成分变化的差异。结果显示：基于过氧化值达到国标限量（≤5 mmol/kg）的精炼菜籽油、浓香菜籽油的预测货架期分别为64 d和80 d，浓香菜籽油的氧化稳定性明显优于精炼菜籽油；利用同时蒸馏萃取结合气相色谱-质谱联用法（SDE-GC-MS）对两种菜籽油中挥发性成分进行检测分析发现，在初始浓香菜籽油和精炼菜籽油中分别检出10类84种和6类51种挥发性成分，总量分别为11 110.78 μg/kg和3 831.28 μg/kg；浓香菜籽油中含量最高的是硫苷降解产物，其次是烯烃类和酚类物质，分别占总量的32.04%、22.74%、...
