Through monitoring Rancimat induction time (RIT), peroxide value (POV), and thiobarbituric acid-reactive substances (TBARS) of docosahexaenoic acid (DHA) algae oil and walnut oil during accelerated storage, the effects of the single and the combinations of seven kinds of antioxidants involving ascorbyl palmitate (AP), phytic acid (PA), vitamin E (VE), antioxidant of bamboo leaves (AOB), rosemary extract, tea polyphenols (TP), and tea polyphenol palmitate (TPP) against lipid oxidation were evaluated. RIT, POV, and TBARS results showed that the DHA algae oil sample containing 600 mg/kg TPP revealed the strongest stability and the walnut oil sample containing 450 mg/kg TPP and 100 mg/kg TP revealed the strongest stability. Then, the shelf lives of two oils were predicted from the extrapolation of the linear regression model between Log RIT and temperature. Our results indicated that the optimal antioxidant could prolong the shelf lives of DHA algae oil and walnut oil by 2.31- and 7.74-fold, respectively.
通过监测二十二碳六烯酸（DHA）藻油和核桃油在加速储存期间的Rancimat诱导时间（RIT）、过氧化值（POV）和硫代巴比妥酸反应性物质（TBARS），评估了七种抗氧化剂（包括棕榈酸抗坏血酸酯（AP）、植酸（PA）、维生素E（VE）、竹叶抗氧化剂（AOB）、迷迭香提取物、茶多酚（TP）和茶多酚棕榈酸酯（TPP））单独使用及组合使用时对脂质氧化的影响。RIT、POV和TBARS结果表明，含有600 mg/kg TPP的DHA藻油样品稳定性最强，含有450 mg/kg TPP和100 mg/kg TP的核桃油样品稳定性最强。然后，根据Log RIT与温度之间线性回归模型的外推法预测了两种油的货架期。我们的结果表明，最佳抗氧化剂可分别将DHA藻油和核桃油的货架期延长2.31倍和7.74倍。
