The composite enzyme of the invention can be widely used in the production of xylooligosaccharides, can effectively improve the efficiency of eucalyptus hemicellulose conversion xylooligosaccharides, and the cellulase and mannanase in the composite enzyme can obviously promote the production of xylooligosaccharides. The degradation effect of carbohydrase on hemicellulose, and the synergistic effect of the three enzymes can increase the total conversion rate of xylobiose, xylotriose and xylotetraose by 12.5%, and the conversion rate of xylotetraose is also increased by 50%. But utilize the complex enzyme preparation of this invention to prepare xylopentaose conversion rate is extremely low

The invention discloses a compound enzyme preparation specially used for improving conversion ratio of xylopentaose. The compound enzyme preparation comprises xylanase, phytase and mannose as well as sodium carbonate. The compound enzyme preparation disclosed by the invention has the advantages that pressed liquor produced from viscoses can be taken as a raw material for preparing xylooligosaccharide solution taking xylose as a main ingredient, by virtue of synergistic effect produced by the xylanase, phytase and mannose in the compound enzyme preparation, the conversion ratio of xylopentaose is greatly improved, and xylooligosaccharide solution prepared according to the enzyme preparation and the method in the invention obtains good effect in animal bifidobacterium culture.
Description
technical field [0001] The invention belongs to the technical field of enzyme preparation application, and in particular relates to a special compound enzyme preparation for improving the conversion rate of xylopentaose and its application. Background technique [0002] Xylooligosaccharide is a functional oligosaccharide, which is a mixture of 2 to 7 D-xylose linked by β-1,4-xylosidic bonds, some of which also contain arabinuronic acid and glucuronic acid side chains . Xylooligosaccharide is the active sugar that can most promote the growth of beneficial bacteria in the body among the current functional oligosaccharides. It also prevents oral caries, promotes calcium absorption, lowers blood pressure and serum cholesterol, inhibits intestinal pathogens, and prevents constipation and diarrhea. Function. The application of xylooligosaccharides in the field of feed can improve the intestinal health and digestibility of animals, and improve the immunity of animals. [0003] A...
