Abstract

The pollution of phthalic acid esters (PAEs) in edible oils is a serious problem. In the current study, we attempt to remove dibutyl phthalate ester (DBP) from evening primrose oil (EPO) with modified activated clay. The activated clay, commonly used for de-coloration in the oil refining process, was modified by chitosan and hexadecyl trimethyl ammonium bromide (CTAB). The modifications were characterized by SEM, XRD, and FT-IR. We further tested the DBP adsorption capacity of CTAB/chitosan-clay and found that the removal rate was 27.56% which was 3.24 times higher than with pristine activated clay. In addition, the CTAB/chitosan-clay composite treatment had no significant effect on the quality of evening primrose oil. In summary, the CTAB/chitosan-clay composite has a stronger DBP adsorption capacity and can be used as a new adsorbent for removing DBP during the de-coloration process of evening primrose oil.

壳聚糖和CTAB改性活性粘土去除月见草油中的DBP

邻苯二甲酸酯(PAEs)在食用油中的污染是一个严重的问题。在本研究中，我们尝试用改性活性粘土去除月见草油(EPO)中的邻苯二甲酸二丁酯(DBP)。采用壳聚糖和十六烷基三甲基溴化铵(CTAB)对炼油过程中常用的脱色活性粘土进行了改性。通过SEM、XRD和FT-IR对改性物进行了表征。进一步测试了CTAB/壳聚糖-粘土对DBP的吸附能力，发现其去除率为27.56%，是原始活性粘土的3.24倍。此外，CTAB/壳聚糖-粘土复合处理对月见草油的品质无显著影响。综上所述，CTAB/壳聚糖-粘土复合材料具有较强的DBP吸附能力，可作为月见草油脱色过程中DBP的新型吸附剂。
