Problems solved by technology

However, there are fewer reports on the development of marine algae polysaccharides or oligosaccharides as prebiotics. Chinese patent (CN100372542C) reports that alginate oligosaccharides are used as prebiotics, and Chinese patent (CN1593433A) reports that agar oligosaccharides are used as prebiotics. However, there is no report on the development of seaweed polysaccharides as prebiotics

Embodiment 1

[0013] Take 20 g of crushed centipede algae (Grateloupia filicina), add 600 g of distilled water, stir in a water bath at 90°C for 4 hours, filter out the filter residue with 100 mesh, 200 mesh and 300 mesh sieves successively, and concentrate the filtrate with a vacuum concentration equipment 1 / 10 of the original volume, then ethanol precipitation with 4 times the volume of the concentrated solution in 95% ethanol for 24 hours, centrifuged, and the precipitate was freeze-dried to obtain the centipede polysaccharide.

[0014] The centipede algae polysaccharide obtained above is formulated into a 1% (mass percentage) aqueous solution for use. Commercially available probiotics (mainly a mixture of probiotics such as lactic acid bacteria and bifidobacteria) were activated and amplified with MRS medium. The amplified bacterial solution was placed in a 96-well plate, and different volumes of centipede polysaccharide solutions were taken to make the final concentrations 0.1% and 0.5...

Embodiment 2

[0016] Take 20 g of crushed Eucheuma (E.maricatum), add 800 g of distilled water, stir in a water bath at 70°C for 2 hours, filter out the filter residue with 100 mesh, 200 mesh and 300 mesh sieves successively, and use vacuum concentration equipment for the filtrate. Concentrate to 1 / 10 of the original volume, then ethanol precipitate with 4 times the volume of the concentrated solution in 95% ethanol for 24 hours, centrifuge, and freeze-dry the precipitate to obtain the Eucheuma polysaccharide.

[0017] The Eucheuma polysaccharide obtained above is formulated into a 1% (mass percentage) aqueous solution for use. Commercially available probiotics (mainly a mixture of probiotics such as lactic acid bacteria and bifidobacteria) were activated and amplified with MRS medium. The amplified bacterial liquid was placed in a 96-well plate, and different volumes of Euglena polysaccharide solutions were taken to make the final concentrations 0.1% and 0.5%, and the control was a mixture...

Embodiment 3

[0019] Take 20 g of crushed Gelidium amansii, add 600 g of distilled water, stir in a water bath at 100°C for 2 hours, filter out the filter residue with 100 mesh, 200 mesh and 300 mesh sieves successively, and concentrate the filtrate with a vacuum concentration equipment 1 / 10 of the original volume, then ethanol precipitation with 4 times the volume of the concentrated solution in 95% ethanol for 24 hours, centrifuged, and the precipitate was freeze-dried to obtain the centipede polysaccharide.

[0020] The agaricus polysaccharide obtained above is prepared into a 1% (mass percentage) aqueous solution for use. Commercially available probiotics (mainly a mixture of probiotics such as lactic acid bacteria and bifidobacteria) were activated and amplified with MRS medium. The amplified bacterial solution was taken and placed in a 96-well plate, and different volumes of agaricus polysaccharide solutions were taken to make the final concentrations 0.1% and 0.5%, and the control wa...

Abstract

The invention belongs to the technical field of functional food additives and nutritional health-care products, and particularly relates to the application of algal polysaccharide. The algal polysaccharide is used for preparing prebiotics in the functional food additives and the nutritional health-care products. The algal polysaccharide which is used as a raw material of the prebiotics is from large economic red algae, raw material sources are rich, the production cost is low, the preparation technology is simpler, and the algal polysaccharide has the efficacies of improving the immunity of a human body, preventing and treating tumors and the like, so that the algal polysaccharide which is used as the prebiotics has a quite obvious health-benefiting effect.

Description

technical field [0001] The invention belongs to the technical field of functional food additives and nutritional health products, and specifically relates to the application of seaweed polysaccharide. Background technique [0002] With the development of gut microbiology research, the importance of the reproductive balance of gut microbiota to health has gradually been recognized. Probiotics in the intestinal tract such as bifidobacteria and lactic acid bacteria play an important role in purifying the intestinal tract, improving the body's nutrition and maintaining the health of the host. Prebiotics are substances that are not digested by the host's gastrointestinal tract and can selectively stimulate the growth of one or several beneficial bacteria in the host's intestines, thereby improving the health of the host. [0003] At present, prebiotics can be divided into the following categories: functional oligosaccharides, such as fructo-oligosaccharides, xylo-oligosaccharide...
