This experiment adopts the secondary fermentation to brew pineapple vinegar, and through orthogonal experiments, conducts the formula reasearch about pineapple vinegar beverage. Acetic acid fermentation through single factor experiment results shows that: the adictive amount of Acetic acid bacteria powder has no effect on the product of Acetic acid. Orthogonal test shows that: the optimum proportion of pineapple vinegar beverage is pineapple vinegar 1g, pineapple juice 1g, white sugar 1g, sterilization 1min. Physical and chemical parameters were measured..., processed pineapple vinegar beverage total acid..., soluble solids..., reducing sugar content. Determination of microbial indicators..., the total number of bacterial colonies..., the total number of E. coli colonies 0MPN/100ml.
