The production processing of Passiflora edulis vinegar was studied.Based on single experiments,the optimal parameters of alcohol fermentation were confermed through orthogonal experiment as follows:fermentation temperature at 30℃,14g/100mL sugar,0.15% inoculation quantity.The response surface methodology(RSM)was employed to study the optimal parameter of acetic fermentation,the optimal parameters as follows:fermentation temperature at 32.5℃,6% of initial alcohol content,11% inoculation quantity.Under these ...
