| 中文摘要: |
| 旨在为植物油脱臭馏出物（DD 油）相关标准的制定以及产品的开发提供参考，收集了全球35个不同工厂来源大宗油料的DD油，对其理化指标、不皂化物和危害因子进行分析。结果表明：35个DD油样品的酸值（KOH）为68.1～191.3 mg/g，过氧化值为0.043～0.149 g/100 g，水分及挥发物含量为0.18%～1.98%，灰分含量均小于0.3 g/100 g，皂化值（KOH）为125.0～205.8 mg/g，不皂化物含量为2.80%～35.71%；DD油样品的植物甾醇含量为0.81%～18.23%，维生素E含量为0.13%～9.23%，角鲨烯含量为0.09%～2.56%；DD油样品中PAH4总含量为6.74～61.98 μg/kg，6种邻苯二甲酸酯（DEP、DMP、DIBP、DBP、BBP、DEHP）总含量为1.12～17.57 mg/kg。不同DD油理化指标、维生素E和植物甾醇含量存在较大差异，且样品中多环芳烃和塑化剂的污染水平较高，在DD油相关标准的制定及产品开发的过程中应给予必要的关注。 |

| In order to provide reference for the formulation of relevant standards and product development of vegetable oil deodorizer distillate (DD oil), DD oil from 35 different factories around the world was collected and its physicochemical properties, unsaponifiable matter and hazard factors were analyzed. The results showed that the acid value of DD oil samples was 68.1-191.3 mgKOH/g, the peroxide value was 0.043-0.149 g/100 g, the moisture and volatile matter content was 0.18%-1.98%, the ash content was less than 0.3 g/100 g, the saponification value was 125.0-205.8 mgKOH/g, and the unsaponifible matter content was 2.80%-35.71%. The contents of phytosterol and squalene, vitamin E and squalene were 0.81%-18.23%, 0.13%-9.23% and 0.09%-2.56%, respectively. In addition, the total content of PAH4 in DD oil samples was 6.74-61.98 μg/kg, and the total content of six phthalates (DEP, DMP, DIBP, DBP, BBP, DEHP) was 1.12-17.57 mg/kg. The physicochemical properties, vitamin E and phytosterol contents of different DD oil are quite different, and the pollution level of polycycilic aromatic hydrocarbons and plasticizers in the samples is high. Therefore, necessary attention should be paid to the formulation of DD oil related standards and product development. |
