Fatty acid esters of 3-monochloropropanediol (3-MCPD) and glycidol are processing contaminants found in a wide range of edible oils. While both 3 MCPD and glycidol have toxicological properties that at present has concerns for food safety, the published occurrence data are limited. Occurrence information is presented for the concentrations of 3-MCPD and glycidyl esters in 116 retail and/or industrial edible oils and fats using LC-MS/MS analysis of intact esters. The concentrations for bound 3-MCPD ranged from below the limit of quantitation (<LOQ) to 0.09 mg kg⁻¹ (ppm) in 22 unrefined oils and from 0.005 to 7.2 mg kg⁻¹ (ppm) in 94 refined oils. The concentrations for bound glycidol ranged from <LOQ to 0.03 mg kg⁻¹ (ppm) in unrefined oil samples and from <LOQ to 10.5 mg kg⁻¹ (ppm) in processed oil samples. The highest concentrations for both 3-MCPD and glycidol were seen in refined palm oil and palm olein samples. Palm olein samples also contained a higher percentage of 3-MCPD in mono-ester form than any other type of oil.
3-单氯丙二醇（3-MCPD）和缩水甘油脂肪酸酯是在多种食用油中发现的加工污染物。虽然 3-MCPD 和缩水甘油都具有毒理学特性，目前对食品安全存在担忧，但已发表的出现数据有限。本研究使用 LC-MS/MS 分析完整酯，介绍了 116 种零售和/或工业食用油和脂肪中 3-MCPD 和缩水甘油酯的浓度。在 22 种未精炼油中，结合态 3-MCPD 的浓度范围为低于定量限（<LOQ）至 0.09 mg kg⁻¹（ppm），在 94 种精炼油中为 0.005 至 7.2 mg kg⁻¹（ppm）。在未精炼油样品中，结合态缩水甘油的浓度范围为 <LOQ 至 0.03 mg kg⁻¹（ppm），在加工油样品中为 <LOQ 至 10.5 mg kg⁻¹（ppm）。3-MCPD 和缩水甘油的最高浓度见于精炼棕榈油和棕榈仁油样品中。棕榈仁油样品中以单酯形式存在的 3-MCPD 百分比也高于任何其他类型的油。
