采用甲醇钠/甲醇酯转化-苯基硼酸（ PBA ）衍生化-气相色谱质谱（ GC-MS ）联用技术方法，测定食用植物油中脂肪酸3-氯-1，2-丙二醇酯（简称3-MCPD酯）。结果表明，食用植物油棕榈酸油、芝麻油和菜籽油脂3-MCPD酯含量比较高，其含量由高到低分别为51250μg/kg ，10400μg/kg和9990μg/kg。食用菜籽油在保持温度220℃、常压条件不变的情况下，经其他不同脱除工艺处理30 min，油脂中所含的3-MCPD酯无明显变化，这表明油脂的精炼脱臭工序中脱臭温度可能是产生3-MCPD酯的主要原因。

A more desirable method was developed for the determination of fatty acid esters of 3-chloropropane-1,2-diol(3-MCPD-esters) in vegetable oil.3-MCPD was released from 3-MCPD fatty acid esters using transesterification with NaOCH3/methanol.3-MCPD was determined after being derivatized with phenylboronic acid by GC-MS.The results showed that the highest contents of 3-MCPD fatty acid esters in vegetable oils were palm acid oil , sesame oil and rapeseed oil .It were 51250μg/kg, 10400μg/kg and 9990μg/kg, from high to low, respectively .At the con-dition of 220℃and 101.3kpa, 3-MCPD fatty acid esters of rapeseed oil had no obvious change after being treated 30 min by different processes .The results indicated temperature was crucial for the formation of 3-MCPD fatty acid esters.
