Analysis of Trace Compositions of Meilanchun Sesame-flavor Liquor

The measurement results of trace compositions of Meilanchun sesame-flavor liquor were analyzed and compare with other famous liquors.The results showed that,Meilanchun sesame-flavor liquor not only has the unique sesame-flavor components but also contains many kinds of organic acids,fatty acids(ester),alcohols,phenols,pyrazines etc.Among conventional flavoring compounds,the content of aldehyde acetal is 1.2～4.9 times,the content of ethyl lactate and ethyl acetate is 1.3～3.5 times,and the content of linolic acid,oleic acid and ethyl palmitate is 1.4～4.4 times as much as that of other famous liquors.Among trace flavoring compositions,the content of tetramethylpyrazine is higher than that of other sesame-flavor liquor,but lower than some other famous liquors.The content of lactic acid and acetic acid is more than 2 times of that of other liquors but the content of butyrate is lower.
