Description
Technical field
The invention belongs to technical field of plant extraction, particularly sugarcane top and/or sugarcane toppers converted products, its preparation method and application.
Background technology
Sugarcane is a kind of annual or perennial root Perenniporia martius herbaceous plant, is the important source material manufacturing sucrose, and cultivated area is wide and have higher economic worth.Sugarcane stem is upright, and sturdy succulence, white powder is often draped over one's shoulders in surface, and leaf is alternate, and the little sharp mouth shape of edge tool, Hua Sui is compound raceme.Sugarcane taste is sweet, puckery, and property is put down, nontoxic, wherein containing the abundant material such as sugar, moisture, multivitamin, protein, calcium, iron, has effect of clearing heat and promoting fluid, liking quite by people.In China, sugarcane essentialspecies is implanted in the ground such as Guangxi and Yunnan, and annual production reaches more than one hundred million ton, every year while the sugarcane that results are a large amount of, also creates many sugarcane tops and sugarcane toppers.Sugarcane top is one of important feature of sugarcane, provides energy and material by carrying out the growth that photosynthesis is sugarcane.Sugarcane toppers, also claims sugarcane tail, cuts down the general designation of the tender joint in 2 ~ 3, top and dark green blade when being results sugarcane.Sugarcane top and sugarcane toppers are the byproducts of sugarcane, wherein containing materials such as rich in protein, polysaccharide, lignin, cellulose and hemicelluloses.
The macromolecular polysaccharide that cellulose is made up of glucose, water insoluble and common organic solvents is the main component of plant cell wall, is also important chemical industry, food material.Scientific research finds multiple cellulosic method of modifying, gives the function that how new cellulose is more, makes it be widely used in preparing the fields such as paper, plastics, explosive, Scientific Research Equipments and high-cellulose food.Lignin is the class material that aromatic alcohol polymerization is formed, and is present in lignum, and Main Function carrys out sclereid wall by forming intertexture net.There is aromatic radical, phenolic hydroxyl group, alcoholic extract hydroxyl group, carbon back conjugated double bond isoreactivity group in the molecular structure of lignin, can number of chemical reaction be carried out, be widely used in the field such as chemical industry, agricultural.Hemicellulose is the heteromultimer be made up of several dissimilar monose, and these monose comprise wood sugar, arabinose and galactolipin etc., and hemicellulose is combined in the surface of cellulose microfibers, constitutes the interconnective network of hard iuntercellular.Hemicellulose structure amorphous, the degree of polymerization is lower, and easily absorb water swollen, can be acid hydrolysis, basic hydrolysis and oxidation, is mainly used in extracting wood sugar and fermentation alcohol.In sugarcane top and sugarcane toppers, the content of cellulose, hemicellulose and lignin is higher, and these large molecules tangle mutually, not easily degrade, and limits making full use of sugarcane top and sugarcane toppers.So at present, do not have the report about sugarcane top and/or the rational industrial applications of sugarcane toppers, sugarcane top and/or sugarcane toppers resource are not fully utilized.
