Abstract

The invention discloses a preparation method of xylooligosaccharide. The preparation method of the xylooligosaccharide comprises the following steps: carrying out alkaline pulverizing on corncobs andthen freezing the pulverized corncobs to break cell walls, carrying out ultrasonic treatment on the pulverized corncobs in an acidic environment, and successively carrying out AMBERJET 1200H treatmentand Amberlite XAD-16 treatment to obtain a xylan solution for subsequent use; and carrying out enzymolysis on the xylan solution by using xylanase to obtain a xylooligosaccharide solution, and crystallizing the xylooligosaccharide solution. The yield of the obtained xylan solution is high, therefore, the yield of the xylooligosaccharide is increased, and moreover, the provided preparation methodis simple and is easy to operate.

Description

technical field [0001] The invention belongs to the technical fields of chemical industry and food, and in particular relates to a preparation method and application of xylooligosaccharide. Background technique [0002] Xylo-oligosaccharides, also known as xylo-oligosaccharides, are functional polymeric sugars formed by combining 2-7 xylose molecules with β-1,4 glycosidic bonds. One of the strongest varieties, xylooligosaccharide has many unique functions: 1. Xylooligosaccharide is difficult to be decomposed by human digestive enzymes. Digestion experiments with saliva, gastric juice, pancreatic juice and small intestine enzyme juice showed that various Digestive enzymes can hardly decompose xylo-oligosaccharides, and the energy value of xylo-oligosaccharides is almost zero, neither affects blood sugar concentration, nor increases the level of insulin in blood sugar, and does not form fat deposits, so it can be used at low It plays a role in energy food and satisfies the ne...
