Embodiment 1

[0052] Soak the dried white fungus fruit body in water, after swelling, remove the yellow-brown base and clean it; put the washed raw material into an extraction tank, add water 100 times that of the dry material, stir and extract at 100°C for 4 hours, Then filter, and the supernatant finally passes through a filter with a pore size of 0.1-1 μm; under uniform stirring, fully mix the filtrate and ethanol, so that the final concentration of ethanol in the mixed liquid is 85%, collect the precipitate, dehydrate with pure ethanol, and collect Precipitation; Freeze-drying at -40°C and crushing to obtain Tremella heteropolysaccharide extract (WSK-1). The yield of the product is 20% (based on the weight of dry white fungus), and the purity of the white fungus heteropolysaccharide is 80%.

Embodiment 2

[0054] Remove the yellow-brown base of fresh-keeping and refrigerated white fungus and clean it; put the washed raw material into the extraction tank, add water 15 times that of the fresh material, stir and extract at 100°C for 4 hours, then filter, and the clear liquid is finally Pass through a filter with a pore size of 0.1-1 μm; the filtrate is heated and concentrated to obtain a concentrated solution; under uniform stirring, the filtrate and ethanol are fully mixed so that the final concentration of ethanol in the mixed liquid is 85%, and the precipitate is collected. Dehydrate and decolorize with ethanol, collect the precipitate; dry with hot air at 80°C, and pulverize to obtain Tremella heteropolysaccharide extract. The product yield is 2.1% (by weight of fresh white fungus).

Embodiment 3

[0056] The tremella fermented liquid obtained by microbial fermentation was heated at 100°C for 0.5h, filtered conventionally, the filter residue was discarded, and the clear liquid finally passed through a filter with a pore size of 0.1-1 μm; under uniform stirring, the filtrate and ethanol were fully mixed to make The final concentration of ethanol in the mixed liquid was 85%, and the precipitate was collected, dehydrated and decolorized with 100% ethanol, and the precipitate was collected; freeze-dried at -40°C, and pulverized to obtain Tremella heteropolysaccharide extract. The product yield is 0.55% (calculated by fermentation broth weight).

Abstract

The present invention discloses the use of one kind of tremella heteropolysaccharide or its extract in preparing medicine, beverage, food and health product for promoting the growth and propagation of probiotics, in preparing medicine, beverage, food and health product for treating constipation, in preparing medicine, beverage, food and health product for expelling toxin and nursing face, and in preparing promoter for promoting the in vitro growth and propagation of probiotics.

Description

technical field [0001] The present invention relates to the use of a heteropolysaccharide; in particular, to the use of a tremella heteropolysaccharide or its extract in promoting the growth and / or reproduction of probiotics, as well as in improving constipation, detoxification and beauty. Background technique [0002] Bifidobacterium is a physiological bacterium in the human body. It is Gram-positive, non-spore-free, non-moving, and strictly anaerobic. Beneficial bacteria with many important physiological functions. With the rapid development of microbiology, the clinical health care function of bifidobacteria is gradually recognized and accepted by people. Human physiology, immunity, nutrition, digestion, anti-tumor, anti-aging, drug efficacy, etc. are all inseparable from the microbiota carried by the human body, and the bifidobacteria in the human intestinal tract have the functions of curing diseases, preventing aging without diseases and health care. role. For examp...
