摘　　要：在精炼油加工过程中,采用半脱酸工艺辅助水蒸气蒸馏脱臭降低油脂中塑化剂邻苯二甲酸丁酯(DBP)、邻苯二甲酸二(2-乙基)己酯(DEHP)含量。以精炼茶籽油为例,通过优化半脱酸中和油游离脂肪酸(FFA)含量、脱臭温度及搅拌蒸汽量得到最佳脱除条件。结果表明:当半脱酸中和油FFA质量分数范围为0.10%~1.75%,均能提高脱臭时塑化剂DBP和DEHP的脱除率,其中当FFA质量分数为1.25%时,塑化剂DBP和DEHP脱除率最高,脱臭条件选择搅拌蒸汽量约800 mL/min,脱臭温度240℃,DBP和DEHP脱除率分别为93.75%、87.61%。而采用传统精炼工艺且脱臭温度为255℃得到的成品油DBP和DEHP脱除率分别为80.47%、74.53%。半脱酸工艺成品油反式脂肪酸明显低于传统工艺,达到“0”反式脂肪酸;3-氯丙醇酯和缩水甘油酯质量分数对比传统工艺分别降低48.10%、37.38%,达到欧盟限量要求;且基本理化指标与传统工艺无明显差别,均符合国标要求。In the process of refined oil processing,the content of dibutyl phthalate(DBP)and Di(2-ethtlhexyl)phthalate(DEHP)in vegetable oil was reduced by semi-deacidification assisted steam distillation.Refined camellia oil was used as an example.The optimal removal conditions were obtained by optimizing the fatty acid content in semi-deacidified neutral oil,deodorization temperature and stirring steam.The results indicated that,when the FFA content was 0.10%~1.75%,the removal rate of DBP and DEHP could be improved during deodorization.When the FFA content was 1.25%,the deodorization conditions were about 800 mL/min and the deodorization temperature was 240℃,the removal rates of DBP and DEHP of refinning oil were the highest,being 93.75%and 87.61%,respectively.The removal rates of DBP and DEHP were 80.47%and 74.53%,respectively,when the traditional refining process was used,and the deodorization temperature was 255℃.The trans fatty acids of the semi-deacidification process were significantly lower than that of the traditional process,reaching"0"trans fatty acids.The contents of 3-MCPD ester and glycidyl ester were reduced by 48.10%and 37.38%,respectively,compared with the traditional process,and all met the EU limit requirements.There was no obvious difference in the basic physicochemical indexes,meeting the requirements of national standard.The research will provide a low-temperature,high-efficiency and safe technology for the control of plasticizers in refined camellia oil.
