| 摘 要： | 以石榴籽为原料,利用超声波辅助提取石榴籽油,采用气相色谱-质谱(GC-MS)联用技术分析其脂肪酸组成,并对其理化性质及自由基清除能力进行了研究。结果表明:石榴籽油的主要成分是石榴酸58.68%,二十碳三烯酸15.02%,亚油酸6.06%,油酸6.46%等。理化测定结果表明:石榴籽出油率为23.53%,折光率为1.5168,皂化价为181.67mgKOH/g,碘价为150.9gI2/100g,酸价为0.81mgKOH/g,过氧化值为0.91meq/kg,相对密度为0.906g/mL;DPPH.及.OH最大清除率分别达83.62%和90.16%,可见石榴籽油是值得开发利用的营养保健油源。
