Problems solved by technology
[0003] Chitosan is insoluble in water. Even chitosan with a deacetylation degree higher than 95% can only be dissolved in water in a small amount under heating, and the amount of dissolved chitosan is far from meeting the requirements for use.
Chitosan is insoluble in water, which limits the effective development and application of chitosan to a large extent.
At present, the use of chitosan usually adopts under the condition of heating, chitosan is slowly added in the aqueous solution of high-concentration acetic acid or hydrochloric acid, stirs for a long time to form chitosan-acetic acid or chitosan-hydrochloric acid aqueous solution, The chitosan acidic aqueous solution has strong acidity and corrosiveness, and is highly polluting and destructive to the human body, animals and plants, and the surrounding environment, greatly limiting the use range and effect of chitosan
In addition, the preparation method of the chitosan aqueous solution requires the equipment to have the characteristics of temperature resistance and corrosion resistance, which requires more energy consumption and high cost for production and use; at the same time, the prepared chitosan aqueous solution is prone to aggregation and sedimentation after being placed for a period of time As a result, the performance is significantly reduced, resulting in a shorter effective service life of the aqueous solution product; in addition, the preparation of the chitosan aqueous solution also increases the storage and transportation costs of the product

The invention discloses a water-soluble chitosan combination agent and an application thereof. The water-soluble chitosan combination agent is prepared from, in parts by mass, 10-80 parts of chitosan, 20-90 parts of solid acid composition and 0.01-5 parts of essence, wherein the essence comprises one of or a combination of more of natural essence, equivalent natural essence and artificially synthesized essence; the deacetylation degree of chitosan is larger than 50%, and the purity of the solid acid composition is higher than 90%; the deacetylation degree of chitosan is preferably larger than 50%. The application of the water-soluble chitosan combination agent includes dispersing the water-soluble chitosan combination agent in water to form a water solution of the chitosan combination agent, and applying the water solution of the chitosan combination agent to the fields about air purification, bacteriostasis, moisturizing, dust control, freshness keeping, water purification, cosmetics, food and the like.
Description
technical field [0001] The invention relates to a chitosan water-soluble composition and its application in the fields of air purification, antibacterial, moisturizing, dustproof, fresh-keeping, water purification, cosmetics, food and the like. Background technique [0002] Chitosan, also known as deacetylated chitin, is the only natural active polysaccharide fiber with positive cationic charge in nature. Chitosan is obtained by deacetylation of chitin widely present in animal shells such as shrimps and crabs and plant cell walls such as fungi and algae in nature. The chemical name is polyglucosamine (1-4)-2-amino- B-D Glucose. Chitosan has cationic positive charge, large molecular weight, high viscosity, good biocompatibility, non-toxic environmental protection, edible, broad-spectrum antibacterial, biodegradable, heavy metal ion chelating, film forming Fiber and other properties have good application prospects in environmental protection, food, medicine and health, agric...
