Abstract: Black-rice juice made by the way of saccharificating and alcoholic fermenting mixed with red-jujube fruit juice in proper proportion. Then found out the optimum proportion between black-rice juice and red-jujube fruit juice, and researched the stability of the drink by the orthogonal experiments. We could get a kind of fermentable drink which has rich nutrition, balanced diet, strong and flavor smell using black-rice and red-jujube fruit as major material.

Key words: black-rice, red-jujube fruit, saccharification and fermentation, stability, beverage
