Pure Chitosan Powder
Description
Pure Chitosan Powder – Premium Grade Biopolymer from Shaanxi Nuoyuan Biotech
Pure Chitosan Powder is a high purity cationic biopolymer, produced from chitin by sophisticated deacetylation techniques. Our product is obtained mostly from crustacean shells and has a Deacetylation Degree (DDA) of 90%, guaranteeing high solubility and bioactivity. Produced in our 30,000㎡ accredited facility with an annual processing capacity of 20,000 tonnes, we provide batch-to-batch consistency that addresses important industry pain points: inconsistent molecular weight, residual protein contamination and poor solubility efficiency.
Our product has ultra-low impurity levels, with ash content below 0.5% and heavy metals below 10ppm, therefore it is suitable for pharmaceutical, nutraceutical and cosmetic applications. It is a positively charged polysaccharide comprised of β-(1-4)-linked D-glucosamine, and it binds well with negatively charged molecules. This particular characteristic is advantageous in improving performance in fat binding, antibacterial formulations and pharmaceutical delivery systems.
We have 5 sets modern HPLC testing equipment and more than 15 years OEM/ODM expertise, guarantee stable quality, fulfil worldwide regulatory requirements.

Pure Chitosan Powder Key Benefits and Applications
Your formulation challenges require reliable, functional ingredients. Our product delivers measurable benefits across multiple industries.
Weight Management & Cholesterol Support
When you add chitosan to dietary supplements it is capable of binding with as much as 5 times its weight of dietary lipids in the digestive system. This will block fat absorption and promote healthy levels of LDL cholesterol. Consistent benefits have been shown in clinical investigations when taken 30 minutes before a meal.
Excellence in Water Treatment
We have industrial customers that trust our chitosan for heavy metal chelation and removal of suspended solids. The positive charge allows effective flocculation at lower doses than synthetic polymers. You will have clearer effluent while achieving environmental compliance.
Advanced Biomedical Application
Pharmaceutical developers appreciate our ultra-low protein content for wound dressings, haemostatic products and controlled-release medication carriers (minimising immunogenic risk). The constant viscosity profile results in predictable performances for hydrogel applications and microencapsulation.
Agriculture & Preservation of Food
Chitosan is an eco-friendly antibacterial ingredient that also increases shelf life without using synthetic preservatives. Natural seed coverings increase your agricultural goods by increasing the rate of germination and resistance to fungus.
Manufacturing Excellence & Quality Assurance
Quality is not only a guarantee, it is our operating standard. Our manufacturing procedure follows the strictest pharmaceutical grade norms.
We obtain raw ingredients from verified vendors only. Each batch is carefully demineralised, deproteinised and deacetylated in a regulated manner at optimum temperatures below 65°C. This maintains polymer integrity while meeting specified purity levels.
We have an in-house laboratory with 5 HPLC systems, which monitor in real time to ensure each parameter is in line with your criteria. You may also obtain third-party testing results to check they meet USP, EP and JP requirements.
With year-round inventory and a 20,000-ton annual capacity, we eliminate supply disruptions. Your production schedule stays on track with our rapid 7-15 day delivery windows for commercial orders.

Comprehensive Certification & Compliance
We understand global market requirements for Pure Chitosan Powder demand verifiable credentials. Our certifications include:
ISO 9001 Quality Management System Certificate

FAQ
Q: What is the smallest amount you can order?
A: We accept sample requests of 100g upwards for testing. Trial orders from 1kg, our business MOQ is 25kg. Call us to talk about your unique requirements.
Q: How do you ensure consistent product quality?
A: We run each batch to 5 of our HPLC machines for DDA, viscosity, heavy metals and microbiological. Each cargo is fully traceable via the COA records.
Q: Does chitosan affect nutrient absorption?
A: Yes, it may impair absorption of fat soluble vitamins (A, D, E, K). For optimum effects, we suggest taking the supplements at least 4 hours apart from the product.
Q: Is your chitosan vegan friendly?
A. Our typical product is based on crustacean. Our chitosan from a fungus source has identical specs. Contact us for vegan applications.
Q: Which paperwork you offer for custom clearance?
A: We provide Commercial Invoice, Packing List, COA, Certificate of Origin, and related certificates (Halal/Kosher/FDA). More materials available upon request.
Q: Do you offer custom specifications or OEM services?
A: Of course. Our R&D team can modify DDA, viscosity and particle size to your formulation needs. We also do private labelling and manufacture final products.
