Application of dextran, what is dextran?

Dextranrefers toGlucoseIt is a homopolysaccharide composed of monosaccharides, and glucose units are connected by glycosidic bonds.

According to the type of glycosidic bond, it can be divided into alpha-glucan and beta-glucan. Among the alpha-glucan that is most studied and used, dextran, also known as dextran. is a polysaccharide.

It is present in the mucus of some microorganisms that secrete the chain of Lu Liang during the growth process. Depending on the type of microorganism and the conditions under which it grows, so does its structure.

Thousands of years ago, human beings used baker's yeast to ferment bread and wine, and in the modern food industry, it is widely used as a staple food for human beings: bread, steamed bread, steamed buns, biscuits and cakes.

and other excellent starter and nutrients for food. With the development of biotechnology, scientists have started from baker's yeast cell walls.

Extract a type called"Beta glucan"The substance, which has good functions, can now be widely used in the food industry.

Applications

Gels made of dextran are commonly used for biochemical separations, such as column chromatography.

with sucrose. Fermentation to obtain a chemically modified dextran, the trade name of cross-linked dextran. This dextran has a cross-networked structure in its molecules, which can be used as a molecular sieve.

to separate low molecular weight compounds from high molecular weight compounds.

Polydextrose is a water-soluble dietary fiber with the chemical formula (C6H10O5)N.

It is white or off-white solid particles, soluble in water, solubility of 70%, pH value of 10% aqueous solution, no special taste, is a food component with health care function of Yiqing's liquid, and can supplement the water-soluble dietary fiber required by the human body. After entering the human digestive system, it produces special physiological and metabolic functions, thereby preventing constipation and fat deposition.

Applications:

Health care products: can be directly taken in capsules, tablets, oral liquids, granules, etc., with a dosage of 5 15 grams per day; As a health care product dietary fiber answer ingredient dosage:.

Flour products: steamed bread, bread, pastries, biscuits, dried noodles, instant noodles, etc. Dosage:.

Meat products: ham sausage, luncheon meat, sandwiches, meat floss, fillings, etc. Dosage:.

Dairy products: milk, soy milk, yogurt, formula, etc. Dosage:.

Drinks: all kinds of fruit juices, carbonated drinks. Dosage:.

Liquor: added to liquor, rice wine, beer, fruit wine and medicinal liquor to produce high-fiber health wine. Dosage:.

PolydextroseIt is a water-soluble dietary fiber. After eating, it has the function of keeping the stomach and intestines smooth. In addition to the unique effects of insoluble dietary fiber such as significantly increasing fecal volume, enhancing laxative, and reducing the risk of intestinal cancer, polydextrose also has functions that insoluble dietary fiber does not have or are not obvious, such as binding to remove bile acid in the body and significantly reducing serum cholesterol.

Functions of polyglucoseAfter polyglucose enters the human body, it can promote intestinal lactobacilli and bifidobacteria.

and other beneficial bacteria, inhibit the reproduction of harmful bacteria, thereby regulating the intestinal flora.

Moreover, polyglucose has a complex structure and is difficult to be degraded into glucose, so the caloric content is very low, does not affect blood sugar, and is suitable for diabetes.

A functional food for patients.

Regulating lipid metabolismPolydextrose can create a membrane in the small intestine and wrap some food fats, which can effectively limit the absorption of fat in the digestion of imitation spring passages, promote the excretion of lipid compounds, increase the satiety of Wang Qin, and reduce the amount of food eaten, so as to regulate blood lipids, reduce fat accumulation, and prevent obesity.

Glycans refer to homopolysaccharides composed of glucose as a monosaccharide, and glucose units are connected by glycosidic bonds. According to the type of glycosidic bond, the wild front bridge can be divided into alpha-glucan and beta-glucan. The most researched and used sugar in alpha-glucan is dextran, also known as dextran.

is a polysaccharide. It is present in mucus secreted by certain microorganisms during growth. Dextran has a high molecular weight, mainly connected by d grape pyranose with , 1 6 bonds, and 4 links at the branching points.

Depending on the type of microorganism and the conditions under which it grows, so does its structure.

Basic characteristics: 1. It is one of the bacterial polysaccharides, also known as dextran, which is produced by the bacteria cultivated in sucrose solution [Leuconostoc enterospermica, dextran sucrase, dextran venuctoctobacterium catalyzed by the following reactions: N sucrose dextran + N fructose.

In the industrial subsp. oxidized Glucobacterium [previously the bacteria containing this substance were called Acetobacterium viscosus and Acetobacterium capsulatus, dextran is synthesized from dextrin. There are many types of dextran, which are composed only of D-glucose, and the backbone is (1,6) bonds, and there are branched chains with (1,4) or (1,3) bonds. Glucose is a white powder, and adding a little bit to water produces strong dextinator.

It is used as a substitute plasma in medicine.

2. It is a general term for polysaccharides with glucose as the constituent sugar. Due to the different binding styles of D-glucose residues, they are divided into many kinds and are widely distributed in microorganisms, plants and animals. Among the representative ones are polyglucose of bacteria, kelp polysaccharides of brown algae, xylan of lichens (-1,4 and -1,3 bonds), cellulose of higher plants, (1,4 binding), amylopectin (-1,4 bonds), amylopectin (side chains of -1,6 bonds on the main chain of -1,4 bonds), glycogen reprimand crude of animals, etc.

Dextran mainly refers to a kind of polysaccharide composed of glucose as a monosaccharide, and the molecular structure of a polysaccharide formed by the glycoside is connected by glucose monoglycoside, which is mainly found to have the following physiological effects:

1. Improve the body's immunity, the ability to resist viral and bacterial infections, suitable for workers who have been in a sub-healthy state for a long time, and can improve their immunity.

Second, it can effectively adjust the flora of the digestive tract, promote the proliferation of beneficial bacteria in the body and the excretion of harmful substances in the intestines, so it has obvious benefits for people with long-term bloating, constipation, or chronic diarrhea.

Third, the improvement of insulin, reduce insulin resistance, so for early diabetes, or glucose tolerance has an obvious effect, at the same time, there are experiments to confirm that it can increase the activity of the first one, increase the immune protection function of the first self, and have a certain wrinkle removal and anti-wrinkle effect, so it is deeply loved by young and middle-aged women, and can play a beauty effect. In addition, some people believe that it can reduce blood lipids, reduce low-density lipoprotein in the body, and reduce cardiovascular and cerebrovascular diseases caused by hyperlipidemia.

Therefore, in fact, it has a certain effect on regulating immunity for middle-aged and elderly people who often travel on business, have irregular life, or for middle-aged and elderly people with weak constitution, or severe patients with tumor radiotherapy and chemotherapy.
