Chitosan is a natural biopolymer derived from the shells of shrimp, crabs and other crustaceans. Remarkably versatile, it is used across food, health and cosmetic industries. Here is a complete overview.
What is chitosan?
- Produced by deacetylating chitin, the second most abundant natural polymer
- Biocompatible, biodegradable and non-toxic
- Positively charged, enabling unique functional properties
Key applications
1. Health and weight management
- Known for binding dietary fats in supplements
- Supports cholesterol management goals
2. Food technology
- Used as a natural preservative and edible coating
- Extends freshness of produce and foods
3. Cosmetics and personal care
- Moisturising and film-forming properties
- Used in skincare and hair care formulations
4. Agricultural and water treatment
- Natural fungicide and biostimulant
- Flocculant in water purification
Why quality matters
Degree of deacetylation, molecular weight and purity determine performance. High-quality chitosan powder ensures consistent, reliable results across applications.
