Abstract:With watermelon peel and honey as the main raw materials and microbial fermentation technology，a lactic acid fermented beverage of honey watermelon peel juice with fresh taste and rich nutritional value was developed.According to the single factor experiment results，the optimum fermentation technology of lactic acid fermented beverage with honey watermelon peel juice was determined by L9（34）orthogonal combination design.The results showed that the mass ratio of watermelon cortex to water was 1 ∶1，honey was 6 %，starter inoculation was 6%，and fermentation temperature was 42 ℃.The fermented products were milky white，sour，sweet and refreshing，and had natural watermelon fragrance.
