The Application of Yeast Glucan

The application of yeast glucan

1, The field of application in food
Meat
Yeast glucan were used in meat products to replace fat, starch, improve product texture, taste and so on. Results show that: replace some fat with yeast glucan and starchovercome starch too sticky, thick and hard, easy to lose moisture and other shortcomings. In this way yeast glucan could reducing calorie of meat, improving the meat product’s original crispness.
Reference volume added in ham: 4%.
Baked goods
Yeast glucan are able to produce are more delicious fiber cake with good smell, taste and structure. Yeast glucan can enhance the water holding capacity to extend the shelf life of cakes.
Reference volume :1-5%
Dairy products andbeverages
Yeast β-glucan can be used to make low-fat ice cream and yogurt. While present in dairy products and beverages in the β-glucan can be play the role as fermentation substrate of lactic acid bacteria, bifidobacteria as the beneficial intestinal health.
Reference: 0.2%.
Other Food

Yeast glucan have high viscosity, water holding capacity, emulsion stability and other properties. In the food industry, yeast glucan were usually used as a thickener, stabilizer and emulsifying agent which used seasonings, desserts and other foods. Thammakiti used yeast glucan as an emulsion stabilizer used in mayonnaise. These mayonnaisesare not only effective to maintain emulsion stability, but also to strengthen the role of cellulose to prevent the absorption of lipids, promote cholesterol excretionandincreaseintestinal motility. Thus, in the food industry yeast glucan can be used as dietary fiber, also a high-quality health food additives.
Adding yeast glucan as the main raw material by using a variety of modern food technology such as extrusion, and other processing ultra-fine powder made of glucan dietary fiber base. Using yeast glucan as dietary fiber base, maltitol, sorbitol and other alcohols Isomaltooligosaccharide raw materials, mixing, granulation, drying and other processes tablet after processing, could made low-calorie, regulate blood lipids, blood sugar, improve laxative such as intestinal environment and health functions of glucan dietary fiber chewable tablets. Yeast β-glucan can also be used in the production of noodles, wheat flour, rice flour and oat β-glucan containing water-soluble gel Nutrim-5 hybrid adding alkali, salt and eggs, and found that adding 10 % Nutrim-5 and adding 50% rice flour, noodles be could cooked loss rate and tensile strength and flavor.
Reference volume : 0.1-2%.
Yeast β-glucan can be used as a variety of breakfast, snacks, drinks, snacks and baby food, pet and animal food base.
2,The application in field of medicine
1 yeast β-glucan structure
Yeast β-glucan are natural polysaccharide extracted, molecular weight above about 6500 dalton.Most of yeast β-glucan exist in water insoluble or colloidal particles.
Yeast β-glucan are different from common sugars (such as starch, glycogen, dextrin, etc.). The main difference is that bonds in different ways, usually sugar to 1,4-bond become a linear combination of molecular structure , and β-glucan of 1, 3 -bond as the main key, and contains a number of 1, 6 - bond branched chain. Special way of bonding and intramolecular hydrogen bonds, resulting in β-glucan molecular structure of the spiral and this unique configuration can easily be accepted by immune system.
Yeast physiological function of β-glucan
In 1940s, Louis found that an active substance has immune stimulating effect in yeast cells. Until the 1960s, Nicholas found that β-glucan is the active substance. In 1970s, the research of β-glucan used for the treatment of human disease was began.
Anti-cancer
β-glucan can enhance macrophage activity and phagocytosis. In 1981, the Norwegian Cancer Research Center and the Department of Medical and Physiological Chemistry, University of Uppsala, Sweden by comparing the 42 kinds of natural polysaccharides, found that extracts from the yeast β-glucan can make mice phagocytic capacity of macrophages to 10-fold abovein vivo. In a subsequent study, also noted in other mammals, including humans, have the same immune system response.
Carboxymethyl glucan (CMG)are more obvious inhibition to tumor cells. In liver cells and gastric cancer cell experiments, liver cells CMGare much higher active than the same concentration on the inhibition of normal liver cells.

Improve immunity
β-glucan can not only enhance macrophage phagocytosis, can also increase the immune system other functions. Glucan can enhance the higher mammals, the complement system in plasma lysozyme function, as well as promote the differentiation of cytotoxic T cells and B cells facilitate the differentiation of cells from the plasma-specific anti-bodies. These increase in these immune functions, most with two cell hormones, that is, IL - 1, interleukin – 2. While the yeast β-glucan have been shown to promote both cell hormone secretion, and to improve immunity. Studies have shown that yeast β-glucan can increase plasma concentrations of interleukin.
Function of disease resistance
Mice immunized with a yeast glucan in high concentrations of E. coli injection in hours of death number and blood bacterial concentrations were less than those untreatedmice.It proves the disease resistancefunctions of β-glucan.
Reference volume : 0.5 - 1 g per day for adults. Can be packinginto tablets, capsules.
3, The application in cosmetics
Although yeast glucan can be absorbent swelling, but difficult to dissolve in water, not soluble in ethanol. But yeast carboxymethyl glucan can increase water solubilityto meet the requirements of skin care.
Modified by carboxymethylation, yeast glucan’s water solubility and water absorptionimproved and moisture were markedly increased. Anti-human skin irritation test result shows CMG have good allergy resistance. CMG applied to the skin care cream in cream can improved skin texture and degree of anti-wrinkle effect. So CMG is a good skin care products feature ingredients ingredients.
A variety of cosmetics volume : 0.01-0.2%
