Xylan (oats spelt) - Introduction
Xylan (xylan) is a kind of hemicellulose, which is widely found in plant cell walls and is a carbohydrate second only to cellulose in nature. It is formed by connecting xylose red β-1, 4-glycosidic bonds, with a molecular weight of about 30000(200 sugar units), white amorphous powder, soluble in dilute alkali solution, and with different samples, the optical rotation [α] is D-71 · 2 ° to -109 · 5 °. It exists in the stems and grain skins of plants on land and in the sea. First use dilute alkali to extract from the above material, and then add acid to the pH value of 4.2 to precipitate it. Repeat this process to prepare purer xylan.

Xylan (oats spelt) - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Application | xylan is used in the following industries: 1, food industry: for flour processing, improvement to produce special flour, it can also be used as a terminal to improve the quality of baked and cooked products. To obtain the effect, it is recommended to use it in combination with fungal а-amylase, lipase or glucose oxidase. The recommended dosage is 1.0-3.0g/100 of flour (10-30ppm). 2, beer brewing industry: Decomposition of xylan or pentosan, reduce wort viscosity. Solve the turbidity caused by carbohydrates such as xylan or pentosan. It is especially suitable for the saccharification process of wheat beer or beer with wheat as auxiliary material and the cleaning of filter membrane. Recommended dosage: 100-300g/t malt. 3. Feed industry: effectively degrade the anti-nutritional factor xylan in plant feed, promote the digestion and absorption of nutrients, and improve the utilization rate of feed. Promote the growth of intestinal beneficial bacteria and inhibit the reproduction of harmful bacteria, improve animal immunity, survival rate and production performance. Recommended usage amount: calculated by 10000U/g enzyme activity, 100-300g is recommended to be added to compound feed per ton, and concentrated feed and premix are added in proportion. |
| biological activity | Xylan is the major hemicellulose component in the secondary plant cell wall of flowering plants. Xylan is a polysaccharide composed of xylose units, mainly containing β-D-xylose units linked by cellulose. |
| uses | biochemical research xylan is a Poly five carbon sugar, which is a kind of hemicellulose, it is widely found in plant cell walls and is the only carbohydrate in nature after cellulose. The structural unit of xylan is xylose, and the xylose chain connected by xylosidic bond becomes the main chain, and some groups in the main chain are substituted by side chain groups, and these side chain groups are acetyl group, arabinose group, galactose Group, glucuronic acid, coumaric acid, ferulic acid, etc., xylan is connected with the rest of the plant components such as cellulose, lignin, pectin through side chain groups to form a dense structure, which together constitute the supporting skeleton of the plant body. |
