The effects of part of plum, alcohol content and addition of t-resveratrol on the formation of ethyl carbamate during the fermentation for wine were investigated at a time interval (45 days) for 6 months. The concentration of the ethyl carbamate in plum wine was determined according to KFDA guideline for ethyl carbamate analysis. In the plum wine with 16% or 30% alcohol content, the concentrations of ethyl carbamate were increased with time of fermentation periods. The maximum concentrations of ethyl carbamate in 16% and 30% plum wines after the fermentation for 6 months were 0.071 ㎍/g and 0.188 ㎍/g, respectively. When t-resveratrol was added at the level of 10 ㎍/g in both 16% and 30% plum wine, the concentrations of ethyl carbamate at 6 months were 0.078 and 0.216 ㎍/g, respectively. The addition of t-resveratrol at the level of 300 ㎍/g in both 16% or 30% plum wine, the concentrations of ethyl carbamate at 6 months were 0.078 and 0.169 ㎍/g, respectively. The ethyl carbamate in the plum wine was not formed during fermentation for 6 month as using the flesh of plum, but 0.588 ㎍/g of ethyl carbamate was formed as using plum with plum seed. The addition of 300 ㎍/g of t-resveratrol actually increased the concentration of the ethyl carbamate by 0.088 ㎍/g as fermented for 6 months using plum with seed. These results suggest that the flesh of plum should be used to reduce the formation of ethylcarbamate for production of plum wine and that the addition of t-resveratrol during fermentation of plum wine can not reduce the concentration of the ethyl carbamate.
