Edit the application of this paragraph in the food field.

Common yeasts in food industry can ferment to produce bioactive cell wall polysaccharides under certain conditions, and these polysaccharides have considerable application value in food.

(1) yeast polysaccharide thickener

The viscosity of the solution dissolved in hot water is higher than that of cold water after cooling, and the glue concentration is above 5%. The viscosity increases greatly with the increase of concentration, but the viscosity value is affected by temperature and acidity. Yeast polysaccharide has synergistic effect with locust bean gum, and mixing with CMC can also increase viscosity. In addition, yeast polysaccharide has good freeze-thaw stability, and 8% yeast polysaccharide solution can form gel after heating to 95℃ and cooling.

(2) emulsifier

Mannoprotein in yeast cell wall has the same hydrophilic and lipophilic structure as surfactants and many emulsifiers, which is due to the combination of mannose and protein skeleton. In addition, dextran has good oil-water emulsification stability. Therefore, yeast cell wall can act as emulsifier. It is reported that adding yeast cell wall polysaccharide into oil-water system can form a very delicate and stable emulsion with cheese texture after stirring.

(3) Low-calorie, dental caries-preventing food raw materials

Dextran is a low-calorie food raw material, which is not easily digested and absorbed by human body. It can be added to food instead of high-calorie carbohydrates, effectively reducing the rise of blood sugar, preventing diabetes and controlling obesity. Dextran can't be decomposed by bacteria that produce dental caries in the mouth to produce acid, so it also has the effect of preventing and treating dental caries.

Edit the adsorption function of yeast polysaccharide on pathogenic bacteria in this paragraph.

The main mechanism that yeast cell wall polysaccharide can adsorb pathogenic bacteria is that mannan can interfere with the colonization of intestinal pathogenic bacteria, thus reducing the number of intestinal pathogenic microorganisms such as Salmonella and Escherichia coli. Pathogens in the intestine (Escherichia coli, Salmonella, Clostridium, etc. ) There is a protein substance (butyl structure) on the cell surface or villi. By recognizing the specificity of animal intestinal wall cells, combining with sugars, they colonize and grow on the intestinal wall, causing intestinal diseases. Mannan contained in yeast cell wall is very similar to the pathogen receptor on intestinal wall, and has strong binding ability with butyrate. Therefore, mannan can be competitively combined with pathogenic bacteria. Yeast cell wall material has the characteristics of acid hydrolysis resistance, which can pass through the digestive tract completely without being destroyed and degraded by gastric acid and digestive enzymes, so it can take pathogenic bacteria out of the body through the intestine, thus effectively reducing the occurrence of intestinal diseases. Yeast cell wall also has a strong adsorption effect on mycotoxins, which can effectively resist their toxicity. It is also found that if mannan is modified to a certain extent, its ability to bind mycotoxins such as aflatoxin and corn gibberellin will be further improved. Therefore, mannan in yeast cell wall is called a new adsorbent, which has a wide range of application values.

Antitumor effect

Polysaccharide in yeast cell wall has anti-tumor effect because it can stimulate reticuloendothelial system in vivo to produce a large number of macrophages. The anti-tumor effect of beer yeast polysaccharide is directly related to the activation of macrophages by yeast polysaccharide. Because yeast polysaccharide showed strong anti-tumor effect when inoculated with mouse tumor cells, the anti-tumor effect was obviously reduced or even disappeared after adding macrophage blocker-silicon powder. This situation shows that beer yeast polysaccharide is an activator of macrophages, and its anti-tumor activity is realized by body macrophages. Macrophages kill tumor cells through activation, and activated macrophages attack tumor cells through phagocytosis or cytotoxicity. After the tumor cells are swallowed, lysosomal enzymes released by macrophages are destroyed or macrophages release toxic factors to kill the inoculated tumor cells.

Reduce radiation damage

Yeast polysaccharide can reduce the radiation damage of irradiated animals. The radiation protection effect of yeast mannan on mice irradiated by 8 12Gy60 Coγ rays was studied. It was found that the dynamic changes of survival rate, survival days, 40-day body weight and the numerical differences of peripheral blood white blood cells, red blood cells, platelets and spleen indexes all showed that yeast mannan had protective effect on mice irradiated by 60Coγ-rays. Through these studies, mannan solution has the experimental basis for developing auxiliary drugs for radiation injury protection. The production of mannan preparation also has important parameters.

Antiviral effect

It was found that yeast polysaccharide had obvious anti-poliovirus III, echovirus 6, Coxsackie virus A 16, B3, novel enterovirus 7 1, vesicular stomatitis virus, adenovirus III and herpes simplex virus I and II. Its mechanism of action is that yeast polysaccharide can not only inactivate viruses, but also inhibit viruses inside and outside cells.

Stimulate and improve immune function

Many scholars have confirmed that yeast polysaccharide is non-toxic and non-mutagenic, and can obviously enhance immune function. Yeast cell wall contains a large amount of β- 1-3-D glucan and mannan, which has non-specific immune effect on diseases caused by bacteria, fungi and viruses, as well as stress reactions caused by transportation, population transfer, inoculation and climate. It is found that mannan can activate the immune system response. Yeast polysaccharide can significantly enhance the immune adhesion of red blood cells. After sulfation, the anti-inflammatory effect of yeast mannan was significantly improved. The results showed that the immune enhancement function of yeast polysaccharide was prominent and the immune function was strongly activated after it was encapsulated by liposome.

Yeast polysaccharide should be stored in a cool, dry and ventilated place, used up as soon as possible after opening the bag, and the bag mouth should be tightly tied with bi. This product is produced by high-temperature spray drying, and conventional high-temperature granulation has no effect.
