[Product Characteristics] Main features of polysaccharide: Chitosan is made from selected crab shells, using chitin as raw material, and then refined. It is soluble in water, can dissolve in dilute acids, and can be absorbed by the human body.

Chitosan is widely used in textiles, printing and dyeing, leather, coatings, cigarettes, plastics, cosmetics, food, feed, medicine, healthcare, color film, papermaking, bioengineering, agricultural plant protection, water clarifiers and enzyme immobilization agents, sewage treatment, and other fields.

[Product Appearance and Solubility]

Chitosan appears as a white to light yellow powder, odorless and tasteless. Deacetylation degree is greater than 90%, ash content is less than 0.8%, moisture content is less than 10%, particle size: 100 mesh - 130 mesh. It has high positive charge and cation content, sufficient fluff and burrs (see photo), strong adsorption capacity. After dissolution, the liquid is colorless and transparent, without cotton-like substances, impurities, or insoluble matter. The liquid is transparent throughout.

[Product Applications]

1. Chitosan for cosmetics: Adding chitosan to cosmetics provides good moisture absorption, moisturizing, conditioning, and antibacterial functions. It is suitable for moisturizing creams, shower gels, facial cleansers, mousse, high-end creams, lotions, and colloidal cosmetics.

2. Chitosan for flocculants: Chitosan and its derivatives have excellent flocculation and clarification effects. As a clarifier for beverages, it can quickly flocculate suspended matter, allowing natural sedimentation and improving the yield of the original solution. In traditional Chinese medicine extracts, macromolecular proteins, tannic acid, and pectin can be easily removed with chitosan solution, refining high-purity Chinese medicine components. Utilizing chitosan's adsorption properties, it has good effects in water purification.

3. Chitosan for agriculture, feed, and bait: Chitosan is a natural plant nutrient growth promoter—a raw material for foliar fertilizers. Foliar fertilizers compounded with chitosan can both act as insecticides and disease resistance agents, serving as fertilizers, and also decompose animal and plant residues and trace metal elements in the soil, converting them into plant nutrients, enhancing plant immunity, and promoting plant health. Crab shells are rich in protein and trace elements, which provide good nutritional value when consumed and absorbed by animals.

4. Antibacterial agent: Chitosan and its derivatives have good antibacterial activity, inhibiting the growth and reproduction of some fungi, bacteria, and viruses. They alter the fluidity and permeability of pathogenic bacterial cell membranes; interfere with DNA replication and transcription; and block bacterial metabolism.

5. Fruit and vegetable preservative: The main purpose of fruit and vegetable preservation is to maintain normal quality, taste, nutritional content, and appearance from post-harvest to the shelf period, improving their commercial value. Coating preservation with chitosan forms a permeable and water-resistant film layer, increasing the penetration resistance of various gas molecules and creating a micro-controlled atmosphere. This increases carbon dioxide content and reduces oxygen content in fruit and vegetable tissues, inhibiting respiratory metabolism and water loss, slowing down tissue and structural aging, and thus extending the post-harvest life of fruits and vegetables.

6. Antioxidant: Meat products contain high levels of unsaturated lipids that are easily oxidized, leading to spoilage and deterioration, which shortens the storage time and damages the flavor of meat products.

7. Health food additive: Chitosan is difficult to digest and absorb in the human gastrointestinal tract, can reduce fat, and decrease food calories, making it suitable as a health food additive.

8. Juice clarifier: Juice contains a large amount of negatively charged substances such as pectin, cellulose, tannins, and polypentose, which can cause turbidity during storage. When the positive charge of chitosan adsorbs and flocculates these negatively charged substances, the clarified juice becomes a stable thermodynamic system, allowing long-term storage without turbidity.

9. Chitosan for tobacco (tobacco adhesive): This product can be evenly mixed with tobacco shreds and adheres to the surface of the shreds, enhancing tensile strength, water resistance, and burst resistance. It is not easily broken during processing and is suitable for modern high-speed cigarette machines. This tobacco additive significantly enhances the combustion performance of cigarettes, reduces tar and nicotine content, reduces off-flavors in cigarettes, decreases harmful substances in smoke, improves taste, and enhances aroma. It also effectively inhibits mold growth in tobacco leaves and extends the storage time of tobacco.

Application Areas:

1. Food: Used in dairy products, meat products, baked goods, flour-based products, etc.

2. Feed: Pet canned food, animal feed, aquatic feed, vitamin feed, etc.
