中文摘要:

黄酒中含有微量氨基甲酸乙酯(Ethyl Carbamate),简称EC,直接降低黄酒中的EC含量,具有重要的现实意义。在各种吸附性材料中,优选得特异性功能树脂材料L2、L3,复配后以合适的添加量体积分数10%处理酒样,对黄酒中的EC能较有效减除,去除率在60%以上,基本达到EC限量要求,同时对酒体风味的保持较好。材料对EC的减除为吸热过程,实际应用中需保证作用温度大于20℃。面向中国黄酒中EC含量的直接降低,提供了一个实用、便捷的全新途径。

英文摘要:

Ethyl carbamate(EC) is usually found in Chinese rice wine.It’s very important to directly remove EC from Chinese rice wine.Among various absorptive materials,two specific resins(L2,L3) were selected and mixed for effectively removing EC at a suitable addition of 10%(v/v).The removal rate was higher than 60%,meeting the EC limitation requirement while maintaining most of the components in Chinese rice wine.The removal of EC absorbed heat.And the temperature should be kept higher than 20 ℃ when conducted the removal.These results provided an applicable and convinient approach for directly reduce EC content in Chinese rice wine.
