Method for preparing water-soluble chito-oligose by microwave radiation

Abstract

The invention water solubility shell oligosaccharide preparing method. It includes the following steps: using shell oligosaccharide as raw material, rinsing, drying, soaking in feed liquid, processing microwave radiation degrading to form the mixture of dissoluble shell oligosaccharide and part of un-degraded shell oligosaccharide; then filtering to gain shell oligosaccharide residue and solution, sending the solution into anhydrous alcohol to process alcohol bleeding, drying to gain the finished product. Compared with existing preparing method, it has the advantages of advanced technology, simple working procedure, high purity, reducing production cost, environment protection, saving energy, industrialization scale production etc.

Description

technical field [0001] The invention relates to a method for preparing water-soluble chitosan oligosaccharides by a microwave radiation method, which belongs to physical degradation [0002] technology field. Background technique [0003] Chitosan oligosaccharide, also known as chitosan oligosaccharide, is a natural high-activity animal cellulose product made from chitosan obtained after deacetylation of chitin through high-tech degradation and separation methods. Due to its unique pharmacological effects and the resulting broad market application prospects, it has attracted increasing attention, and has even been praised as the "sixth vital element of the human body" and "soft gold". [0004] Chitin is a pure natural polymer compound that widely exists in crustaceans such as shrimps and crabs, insects, and algae. Its annual biosynthetic resources are as high as 10 billion tons, of which the production of marine organisms is about 10 It is the second largest inexhaustible ...

AI Technical Summary

Problems solved by technology

The disadvantage of the chemical degradation method is that it is easy to produce reaction by-products, which will eventually affect the purity of the product, so the product quality is difficult to control and the stability is poor; the enzymatic hydrolysis method uses certain enzymes to specifically crack and change the molecular structure to achieve the purpose of degradation. Since no other reaction by-products are generated during the entire degradation process, it has become a more commonly used method at present. Its disadvantages are that the process is relatively complicated, the degradation efficiency is low, and the product cost is high. At present, it is only in the stage of laboratory research and small batch trial production. There are still a series of technical problems to be solved for industrial scale production
