Fatty acid esters of chloropropanediols are a kinds of newly emerged food contaminants, especially 3-monochloropropane-1,2-diol (3-MCPD) esters that have been detected in many foodstuffs such as infant formula and edible oils at relatively high levels. Based on the Tolerable Dose Intake (TDI) of 3-MCPD, the intake of 3-MCPD from 3-MCPD esters may cause the health risk to human beings. The researches for the analysis of 3-MCPD esters have been carried out in some institutes abroad, but there were only a few in China. This paper reviews the methods for the determination of 3-MCPD esters in fat-rich foods, including the extraction, hydrolysis, the derivatization of 3-MCPD esters, the total amount of 3-MCPD esters and the amounts of monoesters and diesters of 3-MCPD.
氯丙二醇脂肪酸酯是一类新出现的食品污染物，尤其是3-氯-1,2-丙二醇（3-MCPD）酯，已在许多食品中被检测到，如婴儿配方奶粉和食用油，其含量相对较高。基于3-MCPD的每日耐受摄入量（TDI），从3-MCPD酯中摄入3-MCPD可能会对人类健康造成风险。国外一些机构已开展了3-MCPD酯分析的研究，但中国的相关研究较少。本文综述了富脂食品中3-MCPD酯的测定方法，包括3-MCPD酯的提取、水解、衍生化、3-MCPD酯总量以及3-MCPD单酯和二酯的含量测定。
