Abstract：Compound vinegar of strawberry and tomato was produced by liquid fermentation, and using Anqi yeast and Acetobacter as strains in the paper. The ratio of materials, alcohol and acetic acid fermentation and vinegar blending process were studied. The results showed the best ratio of strawberry juice and tomato juice was 1:1; the best technological parameters of alcohol fermentation were initial sugar content 14%, initial pH value 4.8, inoculation quantity 4% and fermentation temperature 36℃; the optimal technological parameters of acetic acid fermentation were initial alcohol content 10%, inoculation quantity 6% and initial pH value 5.2; the best formula was amount of vinegar 15%, amount of strawberry juice 15%, amount of honey 5% and amount of citric acid 0.04%.
