Embodiment 1

[0028] A preparation method of seabuckthorn soluble dietary fiber, comprising four processes of chlorella culture, electric current fermentation, hydrangea fermentation culture and extraction of soluble dietary fiber in the fermented product, specifically:

[0029] 1. Chlorella culture

[0030] 1. Dry the seabuckthorn leaves in an oven at 80°C, or dry them naturally, pulverize them, and pass through an 80-mesh sieve to obtain seabuckthorn leaf powder for later use.

[0031] 2. Put 5% seabuckthorn leaf powder and 1% fat sea powder into a container, boil for 10 minutes, and put it at room temperature to get sea buckthorn leaf fat sea mixture, set aside.

[0032] 3. Put the mixture of seabuckthorn leaves and fat sea that has been cooled to room temperature into a cuboid glass container with a stirrer, add 0.4% of chlorella culture solution, add 5% of chlorella species, and at 25°C, cuboid Six sides of the glass container were illuminated, the intensity of illumination was 5000 l...

Embodiment 2

[0044] A preparation method of seabuckthorn soluble dietary fiber, comprising four processes of chlorella culture, electric current fermentation, hydrangea fermentation culture and extraction of soluble dietary fiber in the fermented product, specifically:

[0045] 1. Chlorella culture

[0046] 1. Dry the seabuckthorn leaves in an oven at 80°C, or dry them naturally, pulverize them, and pass through an 80-mesh sieve to obtain seabuckthorn leaf powder for later use.

[0047] 2. Put 5% seabuckthorn leaf powder and 1% fat sea powder into a container, boil for 10 minutes, and put it at room temperature to get sea buckthorn leaf fat sea mixture, set aside.

[0048] 3. Put the mixture of seabuckthorn leaves and fat sea that has been cooled to room temperature in a cuboid glass container with a stirrer, add 0.8% of chlorella culture solution, add 10% of chlorella species, and at 25°C, cuboid Six sides of the glass container were illuminated, the intensity of illumination was 5000 lx...

Embodiment 3

[0060] A preparation method of seabuckthorn soluble dietary fiber, including four processes of chlorella culture, electric current fermentation, hydrangea fermentation culture and extraction of soluble dietary fiber in the fermented product, the specific technical scheme is the same as that of Example 2, the difference is through A potentiostatic / galvanostatic device was fed with a direct current of 40mA and fermented at room temperature for 2 days to obtain a current fermented product.

Abstract

The invention relates to a preparation method for sea buckthorn soluble dietary fiber, and belongs to the technical field of biology. According to the specific technical scheme, after raw materials including sea buckthorn leaves, boat-fruited scaphium seeds and the like undergo processes of chlorella culture, current fermentation, and sparassis crispa fermentation culture in sequence, soluble dietary fiber in a fermented substance is extracted. According to the preparation method, the soluble dietary fiber taking sea buckthorns as main raw materials is extracted by a method of combining biological fermentation, electrochemistry and enzyme engineering, so that operation is simple, and pollution is less; the purity of the soluble dietary fiber obtained by the method provided by the inventionis significantly improved; and the produced soluble dietary fiber has enhanced adsorbability in intestinal tracts, and is suitable for large-scale production and popularization.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a preparation method of seabuckthorn soluble dietary fiber. Background technique [0002] Dietary fiber (DF) includes soluble dietary fiber (SDF) and insoluble dietary fiber (insoluble dietary fiber, IDF). Soluble dietary fiber mainly includes storage substances and secretions in plant cells, and also includes some Microbial polysaccharides and synthetic polysaccharides mainly consist of some gums, such as pectin, acacia gum, bean gum, carrageenan, xanthan gum, agar, etc., as well as galactomannan, β-glucan, alginate , sodium carboxymethyl cellulose and fungal polysaccharides. Soluble dietary fiber can expand after absorbing water, and its expansion volume is often larger than that of insoluble dietary fiber, and its adsorption capacity for cholesterol, fat and heavy metal ions is also much greater than that of insoluble dietary fiber. Dietary fiber is more conducive to gastrointes...
