Beta-oligomeric acid, and preparation method and application thereof

Abstract

The invention relates to a novel oligomeric active factor beta-oligomeric acid, and a preparation method and application thereof. The beta-oligomeric acid is oligomeric glucuronic acid with the polymerization degree of 4-20, which is prepared by simultaneously degrading plant cellulose and carboxylating 6th-site hydroxy group. The beta-oligomeric acid prepared by the synchronous degradation and carboxylation technique can be used as a novel biological active factor; the beta-oligomeric acid containing polycarboxyl groups is mainly used as a plant growth regulator for non-characteristic regulation of plant nutrients and reproductive growth in agricultural production, thereby enhancing the yield and quality of the crops; and when being used as a microelement chelate stabilizer, the beta-oligomeric acid can effectively enhance the stability of microelements and promote the absorption and utilization of the plants for the microelements.

[0002] As the biomass resource with the largest production volume in northern my country, plant fiber resources are mainly corn stalks. Scientists have conducted in-depth research on the aspects of feed, fertilizer, energy, and raw materials, and have achieved many scientific research results. , has also been widely used, but due to the special characteristics and extensive regeneration of plant straw fiber resources, at present, there is still a great waste of plant straw resources and a potential threat to the environment. The development of plant straw energy my country has made breakthroughs in the development and research of solidification molding technology, but the research on the biodegradation of plant straws into liquid ethanol fuels is very slow. So far, there has not been a substantial breakthrough in industrialization. The technical level of fertilizer and feed It is still in the stage of low-value development, and no relevant advanced industrialization technology has been found in the short term. The development of raw materials is still in the stage of CMC production process technology.

Although straw resource processing technology covers physical, chemical, biological or composite technology integration, the development of high-value straw technology is still in its infancy at home and abroad.

In particular, the extraction of bioactive factors of straw fiber resources, the synthesis of derivatives, the identification and application of biological activities, etc., have few basic research reports. Due to the complexity of plant straw fiber structure, in the field of oligosaccharide research, fiber is low Research reports on the preparation of polysaccharides are limited to basic research, and the obtained soluble oligosaccharides are also limited to 4 monomer structures. Oligosaccharides with more than 5 sugars are in a water-insoluble state. However, many research reports have confirmed that oligosaccharides exhibit The molecule with the best biological function is between 6-20 sugars. Due to the insolubility of larger molecules of cellooligosaccharides, the research and development of its biological properties are also limited. In the sugar process, the raw material loss rate is large, the production efficiency is low, the cycle is long, and the product extraction rate is low. So far, no mature and industrialized process technology has been formed.

Therefore, the high-value development research of straw fiber is hindered. The research on the transformation of straw fiber into organic acid is an important research and development direction for the deep processing of straw fiber and the creation of high value-added products, especially the development of polycarboxylates with strong biological properties. Functional oligomeric active substance molecules (composed of 6-20 monosaccharides), there are no public reports on key technologies and related technical standards in this direction at home and abroad
