摘要
采用乙腈提取食用油脂中的抗氧化剂PG、THBP、TBHQ、NDGA、BHA、OG、IONOX-100、DG、BHT,浓缩后用乙腈-水淋洗的反相高效色谱法测定其中的抗氧化剂的含量,方法最低检测限:PG、THBP、NDGA、OG、DG为0.5μg/g,TBHQ、BHA、IONOX-100、BHT为1μg/g,相对标准偏差为1.01%～6.89%,回收率为88.85%～102.57%。该方法简便、快速,稳定可靠。
The determination of nine antioxidants has been studied by using HPLC. After the sample is resolved in hexane and extracted with acetonitrile, and concentrated, it can be determined by HPLC. The detection limit of PG, THBP, NDGA, OG, DG are 0.5μg/g,TBHQ, BHA, IONOX-100, BHT are 1μg/g with relative standard deviation is 1.01%~6.89%. The recoveries of the nine compositions are from 88.85% to 102.57%. The method is simple, efficient and accurate and suitable for analysis of antioxidants in edible oil .
