Abstract

Jiugui Liquor contains five kinds of pyrazine compounds including 2-me thoxy-3-methyl pyrazine,2-methoxy-3-propyl pyrazine,2-methoxy-3-hexyl pyrazine,dimethyl pyrazine and 2-methoxy-3-ethyl pyrazine.The formations of those comp ounds were closely related to pit age,amylum concentration,acidity,and fermen tation time.The flavours of nut,fruits,pea,sesame,peanut and pepper in liqu or could intensify the characteristic flavor of Jiugui Liquor.(Tran.by YUE Ya ng)
