Fermented compound beverage containing collagens and fruits and preparation method of compound beverage

Abstract

The invention discloses a method for preparing a fermented compound beverage containing collagens and fruits and belongs to the technical field of food processing. The method for preparing a fermented compound beverage containing collagens and fruits comprises the following steps: (1) taking the following raw materials in parts by weight: 30-40 parts of watermelons, 0.5-1 part of raisin, 0.01-0.05 part of dried yeast, 2-4 parts of white granulated sugar, 1-5 parts of fish collagen powder, 0.05-0.1 part of VE and 50-100 parts of water; (2) rinsing the raisin with clean water, airing the raisin, crushing the watermelons, adding the white granulated sugar, raisin and water, and finally adding the dried yeast, and uniformly stirring and mixing; (3) fermenting in a closed container for 21-30 days, and controlling the fermentation temperature to be 15-30 DEG C; (4) filtering after fermentation is ended, collecting the filtrate, adding the fish collagen powder and VE, and uniformly mixing; and (5) mixing, performing pasteurization, filling, thereby obtaining the product. According to the method for preparing the fermented compound beverage containing collagens and fruits disclosed by the invention, the compound beverage can achieve the effects of relieving restlessness and quenching thirst, clearing summer-heat, preventing cancers and resisting skin aging and has a beautifying effect.

Description

technical field [0001] The invention relates to a fermented compound beverage containing collagen and fruit and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Most of the early collagen products were extracted from pigskin and cowhide. The better collagen products on the international market are generally extracted from fish. Fish collagen is divided into fish skin collagen and fish scale collagen. Generally, collagen is a macromolecular protein, which is not easily absorbed by the body. The enzymatic hydrolysis product of collagen produced by hydrolysis technology has a molecular weight below 10,000 daltons and contains all the amino acids of collagen. Its good absorption, solubility, water absorption, and moisturizing properties are incomparable to ordinary collagen. . Hydrolyzed collagen is a natural biological product, rich in bioactive substances such as hydroxyproline (>12%) and polypeptides neces...

Problems solved by technology

[0006] In order to overcome the deficiencies in the background technology, the present invention discloses a fermented compound drink containing collagen and fruit and its preparation method. The present invention mixes natural wild yeast attached to the surface of raisins with artificial yeast and watermelon, and utilizes the rich The high-sugar and polyacid nutrients are used as the culture medium, and fermented at a suitable temperature, the fermented beverage obtained has a strong deodorization function, and after being mixed with fish collagen, it solves the collagen product color problem in the background technology well. It retains the nutritional effects of watermelon and raisins, and also overcomes the shortcomings of watermelon, which is cold in nature and should not be eaten more, thereby improving the taste. It is a preventive health drink suitable for long-term drinking
