Abstract

The invention provides a preparation method of a dragon fruit extracting solution, the dragon fruit extracting solution prepared by the preparation method and applications of the dragon fruit extracting solution. The preparation method includes the followings steps: (1) mixing dragon fruit pulp and water, performing squeezing and filtering, and adopting an ion exchange resin column to perform decolorization so as to obtain decolorized dragon fruit squeezing liquid; (2) mixing part of the decolorized dragon fruit squeezing liquid obtained in the step (1) and yeast, and performing fermentation under an anaerobic condition to obtain dragon fruit fermentation broth I; and mixing the rest of the decolorized dragon fruit squeezing liquid obtained in the step (1), acetobacter and lactobacillus plantarum, and performing fermentation under an anaerobic condition to obtain dragon fruit fermentation broth II; and (3) mixing the dragon fruit fermentation broth I and the dragon fruit fermentation broth II obtained in the step (2), and performing fermentation under an anaerobic condition to obtain the dragon fruit extracting solution. The method does not damage the original nutrients of dragon fruits, and the prepared dragon fruit extracting solution is high in biological activity.

Description

technical field [0001] The invention belongs to the field of fruit deep processing, and in particular relates to a preparation method of a pitaya extract, a pitaya extract prepared therefrom and an application thereof. Background technique [0002] Dragon fruit is the fruit of Cactaceae triangular or Serpentine genus, oval in shape, red or yellow in appearance, with green rounded triangular fronds, white, red or yellow pulp, and fruit with black seeds. Dragon fruit is rich in nutrition and has unique functions. It contains plant-based albumin and anthocyanins, which are rare in general plants, and is rich in polysaccharides, vitamins, and water-soluble dietary fiber; Polysaccharides, when applied to the skin, can brighten the skin as a whole, prevent skin dullness and depression, and can play a certain role in sun protection; the content of anthocyanins in dragon fruit is relatively high, which is an effective antioxidant, anti-oxidation, Anti-free radical, anti-aging, anti...
