The Formation Mechanism of Higher Fatty Acid Ethyl Ester in Soybean-flavor Liquor and Effect Formation Factors of Higher Fatty Ethyl Acid Ester

The course of fermentation in Soybean-flavor Liquor,the formation mechanism of higher fatty acid ethyl ester distribute three stages: The first stage,the rice and the Soybeans of big caky starter used as fermentation materials,on the fermentation of yeast,the higher fatty acid ethyl ester is formed;The second stage,on the influence of various enzyme,fatty acid is biosynthesized,then fatty acid and alcohol esterify as higher fatty acid ethyl ester;The third stage,higher fatty acid ethyl ester is hydrolyzed as higher fatty acid and alcohol in the acidity conditions.The more fat of the fermentation materials,the more of the higher fatty acid ethyl ester.The more organic nitrogen of the fermentation materials,can promote the formation of higher fatty acid ethyl ester.
