Directly Removal of Ethyl Carbamate in Chinese Rice Wine

Abstract:

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.
