摘要
随着对缩水甘油酯(GE)的深入研究和检测技术的不断更新,在大多数食用油脂中发现了缩水甘油酯的存在。缩水甘油酯作为一种食用油脂加工过程中产生的污染物,对人体可能存在着致癌性。目前存在对GE的检测有直接方法和间接方法2种,直接方法主要是对油样处理后LC-MS检测;间接方法为缩水甘油酯与苯硼酸衍生化后GC-MS检测。本文对缩水甘油酯的来源、特性及影响因素进行介绍,并对检测方法的标准物质、样品处理过程、仪器条件、结果等加以比较和分析探讨。
With the in-depth research and the update of determination methods of glycidyl esters,they are present in the most of edible oils and fats.Glycidyl ester,a known food processing contaminant,maybe a kind of carcinogen.Presently,existing detection methods are direct and indirect methods.Direct method is detected by LC-MS after the treatment of oil samples,and the latter is detected by GC-MS after derivatization with phenylboronic acid.Based on the sources of glycidyl esters,its characteristics and influence factors,the standard materials,sample processing,instrument conditions,and the results of the determination methods were analyzed.
