Chitosan

Bang Industrial Co., Ltd. Shanghai Qi role of quality suppliers, chitosan phone manufacturers, chitosan CAS number, viscosity chitosan, Shanghai chitosan latest offer, the price of chitosan, chitosan shell glycans factory distributor, chitosan latest offer, the amount of chitosan, welcomed the new and old customers call to discuss. English: Chitosan also known as: deacetylation of chitin, chitosan. CAS: 9012-76-4 Properties: white crystalline powder. Insoluble in water, soluble in acid, formic acid, lactic acid, malic acid, an acidic aqueous solution astringency. Insoluble in phosphoric acid, sulfuric acid, insoluble in neutral or alkaline solution. Chitosan and its derivatives are a good flocculation, clarification of the role. I plant flocculant Chitosan, as a beverage clarifying agent, can make rapid flocculation of suspended solids, natural sedimentation, increase yield dope; in traditional Chinese medicine extract, macromolecular protein, tannin and pectin, It can be easily removed with a chitosan solution, purification of high purity active ingredients of traditional Chinese medicine; the use of adsorption of chitosan, with good results in terms of water purification. Purpose: Chitosan can be used in the food wrap film. Which was coated on the surface of fruits and vegetables, can be artificially formed on the surface of fruits and vegetables a hypoxia and hypercapnia in a closed environment, inhibit the respiration, while antibacterial breeding, fruits and vegetables to improve the gloss and improve the sensory quality of fruit trees. The main purpose is to keep fruits and vegetables fresh fruits and vegetables after harvest until shelf life, can maintain normal quality, taste, nutrition and appearance, increase its commercial value. Preservation with chitosan coating, which film has permeability, water resistance, penetration resistance meat can increase due to the unsaturated lipids contain high levels of easily oxidized leaving the meat to various gas molecules food spoilage, thus shortening the shelf life of meat and destruction of meat flavor. Darmadji and Izumimoto studied the effect of oxidative stability with chitosan-treated beef. It was found that the addition of 1% chitosan, storage for 3 days at 4 ℃, beef thiobarbituric acid reduced by 70% pyrrolidinecarboxylate salt is very effective to inhibit oxidation of cooked, refrigerated 9 days cooked flavor is almost unchanged. He pointed out that, NOOC and chitosan derivatives mentioned in (500-3000) inhibit oxidation effect between × 10-6 respectively 69.9%, 43.4% and 66.3%. This inhibition mechanism of oxidation is the meat of free iron and chitosan-related. When the meat during the heat treatment, iron begins meat free hemoglobin released from, and form chelates and chitosan chelated, thereby inhibiting the catalytic activity of iron ions. Cosmetic: Chitosan has good moisture absorption, moisturizing, conditioning, antibacterial, and other functions; for moisturizer, shower gel, face cream, mousse, high-grade creams, lotions, gels and cosmetics; effectively compensate for the general Chitosan defects.
