Derived from deep-sea crab and shrimp shells, this food-grade chitosan is produced using a process combining low-temperature enzymatic hydrolysis and multi-stage chromatographic purification. Unlike conventional products processed via high-temperature alkaline hydrolysis, the finished product is a uniform, snow-white fine powder free from off-odors, coarse particles, and exogenous impurities. By precisely controlling the deacetylation reaction time, the degree of deacetylation and viscosity can be flexibly customized. Its molecular structure is rich in active amino groups capable of targeted binding with lipid molecules in the digestive tract, making it a key natural ingredient for weight management dietary formulas and gut health supplements.
The entire production process adheres to food-grade cleanroom standards, with testing parameters-such as microbial counts, heavy metals, and residue on ignition-aligned with FCC and EU food ingredient specifications. The product holds full qualifications for cross-border export, ensuring consistent and controllable batch quality.
Exclusive Core Product Advantages
By replacing traditional high-temperature, strong-alkali hydrolysis with low-temperature enzymatic hydrolysis, the molecular chain integrity is better preserved and more active amino sites are retained. This results in superior fat-encapsulating and adsorption capabilities at the same dosage, enhancing the efficacy of fat-reduction formulas without the performance loss caused by high-temperature degradation of molecular activity.
Available in three standard deacetylation grades (85%, 90%, and 95%) with viscosity adjustable to meet specific dosage form requirements. High-deacetylation grades are ideal for capsules and tablets, while medium-viscosity grades suit meal replacement powders and solid beverages, precisely matching the process requirements of various production lines.
The powder is loose and dry, featuring a low angle of repose and excellent flowability, ensuring no clumping or wall-sticking during high-speed mixing. It dissolves smoothly in mildly acidic systems, yielding a clear, non-turbid solution. It is highly compatible with ingredients such as dietary fibers, plant extracts, and vitamins, without compromising the finished product's taste, structural integrity, or shelf life.
Produced via purely physical and biological extraction methods without added medicinal ingredients or controlled chemicals; it is not classified as a regulated drug. Permitted for use as a dietary supplement in the vast majority of countries worldwide, it ensures high customs clearance success rates without the need for complex or special approval procedures.
Accelerated stability testing confirms no significant decline in physicochemical properties after 18 months of storage in a cool, sealed environment. It resists moisture absorption, clumping, and molecular degradation even under the high-temperature and humid conditions of transoceanic shipping, allowing for worry-free bulk purchasing and long-term inventory management.
Core Application Scenarios
Dietary products for fat reduction and weight management
Suitable for fat-reducing capsules, fat-blocking tablets, and meal-replacement powders; utilizes lipid-adsorption properties to inhibit intestinal fat absorption and reduce caloric intake, creating natural, non-irritating slimming dietary products.
Gut-regulating health supplements
Adsorbs excess intestinal lipids and metabolic waste while regulating the intestinal environment; used in the formulation of supplements for gastrointestinal soothing and intestinal cleansing.
Food industry processing aids
Used for the flocculation and clarification of fruit juices and fruit wines, protective coatings for preserving fresh produce, and moisture retention in meat products to enhance overall food quality.
Personal care and pharmaceutical excipients
Serves as a base material for moisturizing skincare products, a carrier for sustained-release pharmaceuticals, and a raw material for wound-healing dressings.
