摘要/Abstract

摘要： 通过对塑料杂质（聚丙烯编织袋和聚乙烯塑料袋）含量不同的花生仁和油菜籽进行浸出取油和压榨取油，并检测浸出毛油和压榨毛油中6 种邻苯二甲酸酯类塑化剂（phthalatic acid esters，PAEs）含量，研究油料中塑料杂质对毛油中PAEs含量的影响。结果发现，随着花生仁和油菜籽中塑料杂质含量的增加，所制取毛油中塑化剂含量也随之增加。油料中不含塑料杂质时，2 种方式提取的花生油和菜籽油样中PAEs平均含量分别为1.130、0.503?mg/kg；聚丙烯编织袋质量分数0.5%时，花生油和菜籽油样品中PAEs平均含量分别为1.538、0.684?mg/kg，分别为不含杂质时的1.36?倍和1.36?倍；聚乙烯塑料袋质量分数为0.5%时，花生油和菜籽油样中PAEs平均含量分别为2.810、1.556?mg/kg，分别为不含杂质时的2.49?倍和3.09?倍；聚丙烯编织袋质量分数增大至1.0%时，花生油和菜籽油中PAEs含量分别为2.245、0.851?mg/kg，分别为不含杂质时的1.99?倍和1.69?倍；聚乙烯塑料袋质量分数为1.0%时，2?种油脂中PAEs含量分别为3.391、2.121?mg/kg，分别为不含杂质时的3.00?倍和4.22?倍。含有聚乙烯塑料袋的油料比含有聚丙烯编织袋的油料受塑化剂污染的风险程度更大，浸出毛油比压榨毛油受塑化剂污染的风险也更为显著。

Abstract: Peanut and rapeseed with different contents of plastic impurities (polypropylene (PP) woven bag and polyethylene (PE) bag) were collected, and crude oils were obtained from the two oilseeds by solvent extraction and pressing, respectively. The contents of six phthalates acid esters (PAEs) in crude oils were detected, and the influence of plastic impurities in plant oilseeds on the contents of PAEs in crude oil was studied. The results showed that the contents of PAEs in crude oil increased with increasing contents of plastic impurities in peanut and rapeseed. The average contents of PAEs in crude peanut and repeseed oil without plastic impurities were 1.130 and 0.503 mg/kg, respectively. The average contents of PAEs in peanut oil and rapeseed oil samples from oilseeds containing 0.5% of PP woven bag impurities were 1.538 and 0.684 mg/kg, respectively, which were 1.36 and 1.36 times higher than that in the corresponding control oils (extracted from oilseeds without plastic impurities), respectively. In the case of oilseeds containing 0.5% of PE bag impurities, the average contents of PAEs were 2.810 and 1.556 mg/kg in peanut and rapeseed oil, respectively, which were 2.49 and 3.09 times higher than that in the control oils, respectively. The contents of PAEs were 2.245 and 0.851 mg/kg in peanut and rapeseed oil from oilseeds with 1.0% of PP woven bag impurities respectively, which were 1.99 and 1.69 times higher than that in the control oils, respectively. The average contents of PAEs were 3.391 and 2.121 mg/kg in peanut and rapeseed oils from oilseeds with 1.0% of PE bag impurities, respectively, which were 3.00 and 4.22 times higher than that in the control oils, respectively. Oilseeds with PE plastic bags caused higher risk of PAEs pollution in oils than with PP plastic woven bags, and the solvent extracted oil had higher risk of pollution than the one obtained by pressing.
