摘要
通过对不同地区20个芝麻样品中邻苯二甲酸酯(phthalatic acid esters,PAEs)组分含量的检测分析,以及芝麻中PAEs在制油过程向毛油中迁移规律研究,明确芝麻油生产中原料和制油工艺对芝麻油PAEs风险的影响,以便准确制定PAEs风险防范和控制技术,确保并提升芝麻油的品质安全。结果表明,20个芝麻样品均不同程度检出PAEs,国标限量控制的邻苯二甲酸二丁酯(dibutyl phthalate,DBP)、邻苯二甲酸二(2-乙基)己酯(di(2-ethtlhexyl) phthalate,DEHP)、邻苯二甲酸二异壬酯(diisononyl ortho-phthalate,DINP)的检出率为100%,3种组分和8种塑化剂总含量(Σ8PAEs)分别为0.040～0.337、0.085～1.971、0.343～0.806 mg/kg和0.209～2.828 mg/kg,平均值分别为0.137、0.560、0.559 mg/kg和1.165 mg/kg。对照国标DBP≤0.3 mg/kg、DEHP≤1.5 mg/kg、DINP≤9.0 mg/kg的限量指标,DEHP超标率为5%,DBP超标率为10%。芝麻原料中的PAEs随着制油过程向毛油中迁移富集,DBP、DEHP、DINP和Σ8PAEs在压榨毛油中的含量分别是芝麻中的1.16、1.03、1.11倍和1.07倍,在浸出毛油中的含量分别是芝麻中的1.49、1.27、1.24倍和1.33倍,脱皮芝麻毛油中PAEs含量比整籽芝麻毛油含量降低约20%,浸出毛油中PAEs含量约是压榨毛油1.2倍。
In this paper,the contents of phthalic acid esters(PAEs)in 20 sesame seed samples collected from different areas were analyzed.The migration of PAEs into crude sesame oil during oil processing was studied.The effects of raw materials and processing technologies on PAEs migration into sesame oil were clarified in order to develop technologies for accurately preventing and controlling the risk of PAEs migration and consequently to ensure and enhance the quality and safety of sesame oil.The results showed that all samples were found to contain PAEs.Dibutyl phthalate(DBP),di(2-ethtlhexyl)phthalate(DEHP)and diisononyl ortho-phthalate(DINP),with limits set for all of them(DBP≤0.3 mg/kg,DEHP≤1.5 mg/kg,and DINP≤9.0 mg/kg)in the Chinese national standard,were detected in 100%of the samples in the range of 0.040–0.337,0.085–1.971 and 0.343–0.806 mg/kg with an average of 0.137,0.560 and 0.559 mg/kg,respectively.A total of 8ΣPAEs were detected in all samples in the range of 0.209–2.828 mg/kg with an average of 1.165 mg/kg.Five and 10 percent of the samples exceeded the national standard limits for DEHP and DBP,respectively.The PAEs were gradually migrated from sesame into crude oil and accumulated during oil production.The contents of DBP,DEHP and DINP and total PAEs content of the crude pressed oil were 1.16,1.03,1.11 and 1.07 times higher than those of sesame seeds,respectively.The solvent extracted oil contained 1.49,1.27,1.24 and 1.33 times more DBP,DEHP and DINP and total PAEs than sesame seeds,respectively.The content of PAEs in the peeled sesame oil was about 20%lower than that in the whole sesame oil,and the PAEs content in the extracted oil was about 1.2 times higher than that in the pressed oil.
