Introduction of Alemei NSP Enzymeβ-mannan is a kind of hemicellulose which widely exists in corn, soybean meal, sesame meal, coconut meal, palm meal and other feed raw materials, which is harmful to the digestion and absorption of animal nutrients. Among those β-mannan, water-soluble β-mannan is the most anti-nutritious hemicellulose, and its anti-nutritional effect is much higher than that of xylan and glucan.The anti-nutritional effect of β-mannan is mainly manifested in the following aspects: increasing the viscosity of intestinal chyme of livestock and poultry, and then resulting in difficult movement of intestinal contents.It hinders the interaction between digestive enzymes and substrate, produces physical obstacles to nutrient absorption, increases its water absorption, and reduces the expansion rate of chyme to the surface of mucous membrane, which greatly affects the absorption and utilization of nutrients. In addition, β-mannan is similar to the pathogen-related molecular structure, which can be recognized by pattern recognition receptors in the intestinal tract, thus inducing redundant immune response.Soluble mannan content in different feed materials (%)Raw materialSoluble mannan content44%CP Soybean meal1.4548%CP Soybean meal1.10Full-fat soybean 90000.90The double low rapeseed meal0.3934%CP sunflower seed meal0.36Coconut meal3.20Corn protein0.0340%CP guar seed meal7.9050%CP guar seed meal3.46Palm meal3.00Pea protein0.30Peanut meal0.36Wheat bran0.15Corn0.03Wheat...

Acid β-mannanaseβ-mannan is a kind of hemicellulose which is most widely spread and has high content in plant except cellulose and xylan. It is a linear polymer formed by β-1,4-D- D-mannose, mainly glucose group, acetylgroup and galactose group, forming the main component of the cell wall of seed plants.β-mannan and its derivatives hinder nutrition absorption in feed, which leads to diarrhea in different degrees, and ultimately affects the growth and feed utilization of livestock and poultry. The anti-nutritional effect of mannan is the formation of gel 'mucus' after dissolving it in water, so as to improve the viscosity of chyme, reduce the contact between endogenous enzymes and nutrients in animals, slow down nutrient absorption by intestinal tract, and adsorb metal ions, such as Ca2+、Zn2+、Na+, and endogenous enzymes, which affect the nutrient digestion and absorption. Moreover, mannosan can cause excessive immune response under stress or disease, affect the absorption of glucose by small intestine, interfere carbohydrate metabolism and the secretion of insulin-like growth factor(IGF-1), thus inhibit the growth of animals. Acid β-mannanase is an endomannanase that mainly hydrolyzes galactomannan, glucomannan, galactomannan and mannan, the main chain of which are all 1,4-β-D-pyran mannose, to oligosaccharide which containing 2~10 residues.Challenge Group has been working with the Feed Research Institute of the Chinese Academy of Agricultural Sciences(CAAS) for more t...
