Abstract

The invention discloses red-pulp dragon fruit and white-pulp dragon fruit compound fruit wine. The fruit wine is made by taking red-pulp dragon fruits and white-pulp dragon fruits as raw materials, the two kinds of fruit juice are mixed to present a ruby red color, the added sodium metabisulfite and citric acid can achieve the color protecting effect, and tartaric acid and citric acid produced in the alcoholic fermentation process also have the protective effect on pigment, so that the dragon fruit wine finally presents a bright ruby red color and can be preserved for a long time (12 months) without fading. Any other kind of fruits is not introduced into the compound dragon fruit wine, so that the dragon fruit wine remains peculiar aroma of the dragon fruits. Therefore, the dragon fruit wine made by the method is bright and transparent in color, full in wine body, typical in fruit aroma, strong in wine fragrance, sour-sweet and palatable, mellow and odor-free. The making cost is reduced, the problem that economic losses are brought by poor sales of the white-pulp dragon fruits can be solved, and the additional value of the dragon fruits is greatly improved. Therefore, the compound dragon fruit wine has wide application prospects and promotes the development of the fermented food industry and fruit wine industry.
