中文摘要：比较低温锡箔烘烤和微波处理2种常用加工方式对南瓜籽油储藏期间中性脂肪酸、磷脂脂肪酸与总脂肪酸组成的影响，同时，通过测定南瓜籽油酸价(Acid value，AV)与过氧化值(Peroxide value，POV)的变化，结合一级化学反应动力学方程和Arrhenius方程建立南瓜籽油储藏动力学模型预测其货架期变化。低温锡箔烘烤和微波预处理的南瓜籽油总脂肪酸中PUFA相对含量均较丰富，从脂肪酸组成角度来看耐储性良好，低温锡箔烘烤组较微波组货架期更长。

外文标题：Effects of Low Temperature Foil Baking and Microwave Treatment on Fatty Acid Composition and Its Shelf Life of Pumpkin Seed Oil

外文摘要：In this study,the effects of low temperature foil baking and microwave treatment on the composition of neutral fatty acids,phospholipid fatty acids and total fatty acids of pumpkin seed oil during storage were compared.At the same time,the changes of acid value(AV)and peroxide value(POV)of pumpkin seed oil were measured,and the first-order chemical reaction kinetics equation and Arrhenius equation were combined to establish the storage kinetics model of pumpkin seed oil to predict its shelf-life changes.The PUFA content in the total fatty acids of pumpkin seed oil pretreated by low temperature foil baking and microwave were rich.From the perspective of fatty acid composition,the storage resistance of the two groups were both good,and the shelf life of low temperature foil baking group was longer than that of microwave group.
