Food Grade

Application of chitosan in food industry: chitosan can be used as adhesive, humectant, clarifier, filler,emulsifier, glazing agent and thickening stabilizer in food industry. It can also be used as a functional oligosaccharide to lower cholesterol and improve immunity. Enzymatic or acid hydrolysis of shrimp skin or crab shell is widely used in industry to extract chitosan. 1.As a carry for immobilized enzyme 2. Used as food additive 3. Used as food packaging film 4. Used for food anticorrosion and preservation

HIGH-DENSITY CHITOSAN

High-density chitosan has 2-3 times the density (≥0.6g/ml) of ordinary chitosan, and its ability to absorb grease is more than 3 times that of ordinary chitosan at the same volume. Generally, only one high-density chitosan capsule is needed to quickly dissolve and adsorb a large amount of grease, cholesterol and chloride ions in a short period of time under the condition of gastric acid, which flocculates in intestinal tract without being absorbed and excreted directly, thus achieving the functions of lowering lipid and blood pressure.

MEDICAL GRADE

Application of chitosan in pharmaceutical indus tr y :Ac cording to the Chinese Pharmacopoeia (Part IV), chitosan is used inpharmaceutical excipients, disintegrants, thickeners, etc. 1. Carrier materials Chitosan, which acts as a drug carrier, is touted for stabilizing the composition of a drug, promoting its absorption, slowing or controlling its dissolution, helping the drug reach its target organ, and being acidresistant, ulcer-resistant as well as preventing gastric irritation. 2. Film forming materials Chitosan can be used as a film-forming material for film preparation, such as oral film preparation and traditional Chinese medicine film preparation. Its relative molecular weight has a prominent influence on the filmforming property and film properties. Generally, the lower the molecular weight, the lower the tensile strength and the stronger the permeability of the film. Appropriate crosslinking agents can be selected to improve the strength and change the barrier properties of the film

INDUSTRIAL GRADE

Application of chitosan in light industry:Taking advantage of the solubility and film-forming property of chitosan as well as the interconvertibility of its chemical structure,acetic anhydride was used as the transformation fixing agent of chitosan-chitin,thus a new type of chitin-type fabric finishing agent without formaldehyde was prepared, which has preferable mechanical strength and chemical stability. Application in environmental protection:Chitosan can be used to treat industrial wastewater and extract heavy metals.Stable chelates can be formed by amino groups, hydroxyl groups and metal ions in molecules, which can be widely applied in the recovery of precious metals, industrial wastewater treatment and other aspects. Soluble chitosan with high viscosity was prepared by chitosan, and the obtained product was of high viscosity, good quality, no toxicity, biodegradability and no secondary pollution.
