Abstract

The present invention discloses dragon fruit peel jelly and a preparation method thereof. The dragon fruit peel jelly comprises dragon fruit peels, white granulated sugar, konjac gum, carrageenan, citric acids, ascorbic acids, a dragon fruit essence and water. The preparation method comprises the following steps: (1) the dragon fruit peels are washed clean, the washed the dragon fruit peels are cut into blocks, then the dragon fruit peel blocks are placed into an ascorbic acid solution to be blanched, the blanched dragon fruit peels and the ascorbic acid solution used for the blanching are mixed, and the mixture is beat to obtain a dragon fruit peel homogenate; (2) the white granulated sugar, konjac gum and carrageenan are mixed and stirred evenly, water is added into the mixture, the mixture is boiled, the boiled mixture is filtered, and the filtered mixture is cooled to obtain a mixed glue liquid; and (3) the dragon fruit peel homogenate obtained in the step (1), citric acids, ascorbic acids and dragon fruit essence are added into the obtained mixed glue liquid in the step (2), the mixture is stirred evenly, the stirred mixture is poured into molds, the molded mixture is cooled, the cooled mixture is taken off the molds, and the finished products are obtained. The dragon fruit peel jelly is bright in color and luster, moderate in sourness and sweetness, and full of elasticity. The method is simple in operation and strong in repeatability.
