87 results about "Carbohydrate composition" patented technology

A carbohydrate is a simple sugar. Its basic structure is composed of the elements carbon, hydrogen and oxygen, with generally twice the hydrogen as carbon and oxygen. In its simplest form, a carbohydrate is a chain of sugar molecules called monosaccharides.

Carbohydrate composition with wound healing promoting effect and application of carbohydrate composition

The invention provides a carbohydrate composition with a wound healing promoting effect and application of the carbohydrate composition. The carbohydrate composition contains at least five types of carbohydrate including carboxymethyl chitosan, rhizoma bletillae polysaccharides, fucoidan from fucus vesiculosus, heparan sulfate, chondroitin sulfate, oligosaccharides of hyaluronan and gulose aldehyde acid oligosaccharides. The carbohydrate composition and the application have the advantages that VEGFA (vascular endothelial growth factor A), FGF2 (fibroblast growth factor 2) and VE-cadherin protein mRNA (messenger ribonucleic acid) expression can be obviously improved by the carbohydrate composition, VEGF (vascular endothelial growth factor) secretion and skin fibroblast (HSF) and human immortalized keratinocyte (HaCaT) proliferation can be obviously promoted by the carbohydrate composition, and the obvious wound healing promoting effect can be realized by the carbohydrate composition; raw materials required by the carbohydrate composition are easily available, composition methods for the carbohydrate composition are simple, the carbohydrate composition is low in cost, easy to industrialize and wide in application range, and the like.

Carbohydrate composition containing yeast beta-glucan and application of carbohydrate composition

The invention discloses a carbohydrate composition containing yeast beta-glucan. The carbohydrate composition is formed by combining yeast beta-glucan with oligosaccharide in the mass ratio of the yeast beta-glucan to the oligosaccharide being (1 to 1000) to (1000 to 1), wherein the oligosaccharide is one or several kinds of fructo-oligosaccharide, isomalto-oligosaccharide, lactose-oligosaccharide, galactooligosaccharide, and xylooligosaccharide; and the carbohydrate composition also comprises one or several kinds of monosaccharide, disaccharide, polysaccharide, maltodextrin and glucose polymers. The invention further discloses an application of the carbohydrate composition for formula foods with special medicine use, wherein the percentage by mass of the carbohydrate composition is 1-90%. The yeast beta-glucan is non-toxic and free from allergic reaction, a special molecular structure can specially activate the immunocyte of organisms, the immune function of the organisms is strengthened, the carbohydrate composition containing the yeast beta-glucan can provide energy, improve immunity, improve the functions of the intestine and the stomach before the operation and can be made into the formula foods to be convenient for patients to use, and the recovery function of the patients after the operation is improved.

Analysis method for measuring carbohydrate composition of polysaccharide

The invention belongs to the technical field of qualitative and quantitative analysis for polysaccharides, and particularly relates to an analysis method for measuring a carbohydrate composition of a polysaccharide. The analysis method for measuring the carbohydrate composition of the polysaccharide comprises the following steps: adequately dissolving the polysaccharide to be measured and an ionic liquid in an oil bath pan to obtain a polysaccharide dissolution liquid, cooling the polysaccharide dissolution liquid and then pouring in a regeneration solvent to obtain a precipitate, repeatedly washing, centrifuging to obtain a regenerated polysaccharide crude product, ventilating to completely volatilize the residual regeneration solvent, and dying to obtain the regenerated polysaccharide; putting the regenerated polysaccharide and an acid solvent in an ampere bottle, sealing, putting the ampere bottle in the oil bath pan and carrying out hydrolysis reaction, centrifuging after the hydrolysis reaction is finished, and carrying out detection pre-treatment on supernatant to obtain a polysaccharide detection liquid; and analysing the type and the content of reducing sugar of the carbohydrate composition in the polysaccharide detection liquid by adopting an ion chromatograph system and an ion chromatograph-pulse amperometry. According to the analysis method disclosed by the invention, the hydrolysis efficiency of the polysaccharide is improved, and the extremely high sensitivity is achieved.
