摘要/Abstract

摘要： 选用4 种大孔树脂和4 种酒类专用活性炭为吸附剂，采用静态吸附法，首先对57%酒精度模拟加标酒样进行吸附实验，以邻苯二甲酸二甲酯（dimethyl phthalate，DMP）、邻苯二甲酸二异丁酯（diisobutyl phthalate，DIBP）、邻苯二甲酸二丁酯（di-n-butyl phthalate，DBP)、邻苯二甲酸二（2-乙基）己酯（diethylhexyl phthalate，DEHP）4 种邻苯二甲酸酯类塑化剂的吸附率为指标进行初选。之后用57%酒精度浓香型原酒进行验证，以塑化剂的吸附率和原酒中己酸乙酯、乙酸乙酯、乳酸乙酯、丁酸乙酯4 种香气成分的损失率作为指标，筛选出理想的吸附剂。结果表明：1）JT201、JT203酒类专用活性炭对模拟酒样中4 种塑化剂的吸附效果较好，平均吸附率为91.01%和87.21%，大孔树脂中非极性的D4006较其他树脂吸附效果好，吸附率达73.67%；极性大孔树脂NKA-Ⅱ和颗粒活性炭的吸附率不足60%，初选JT201、JT203酒类专用活性炭为原酒中塑化剂的吸附剂。2）JT201、JT203酒类专用活性炭吸附后，原酒中DMP、DBP的去除率均达90%以上，JT201对DIBP、DEHP的去除率均达80%以上，JT203对DIBP、DEHP去除率为78%、72%；JT201、JT203吸附处理后原酒中己酸乙酯、乙酸乙酯、乳酸乙酯、丁酸乙酯分别损失7.7%、6.1%、11.9%、11.6%和10.4%、8.6%、33.9%、16.0%，本研究确定JT201酒类专用活性炭为去除浓香型原酒中塑化剂的最佳吸附剂。

Abstract: Static adsorption experiments were carried out with simulated Chinese liquor containing 57% alcohol (V/V) added with dimethyl phthalate (DMP), di-n-butyl phthalate (DBP), diisobutyl phthalate (DIBP) and diethylhexyl phthalate (DEHP) to investigate the adsorption efficiency of four macroporous resins and four special-purpose liquor carbon adsorbents towards the phthalate plasticizers. Further validation experiments were performed with Luzhou-flavor base liquor containing 57% alcohol (V/V) to find the optimal adsorbent for the removal of plasticizers from Chinese liquor based on the adsorption efficiency of plasticizers and losses of four major aroma components including ethyl acetate, ethyl butyrate, ethyl lactate and ethyl caproate. The results showed that the adsorption efficiency of JT201 and JT203 liquor carbon adsorbents towards four phthalate esters was better for simulated Chinese liquor, with average adsorption rates of 91.01% and 87.21%, respectively. The nonpolar resin D4006 had the best adsorption efficiency among four macroporous resins, giving an adsorption rate of 73.67%, while the average adsorption rates of the polar resin NKA-II and active carbon were only less than 60%. Therefore, JT201 and JT203 were chosen as the ideal absorbents. The adsorption rates of DMP and DBP onto JT201 and JT203 were higher than 90%, and the adsorption rates of DIBP and DEHP onto JT201 were higher than 80%, and were 78% and 72% onto JT203, respectively. The loss rates of ethyl acetate, ethyl butyrate, ethyl lactate, and ethyl caproate were 7.7%, 6.1%, 11.9%, 11.6% and 10.4%, 8.6%, 33.9%, 16.0% respectively. In conclusion, JT201 active carbon was chosen as the optimal absorbent for the removal of plasticizers from Luzhou-flavor base liquor in the present study.
