Chitosan Oligosaccharide (COS) Food Grade
CAS No.: 148411-57-8
EC No.: 604-631-8
Molecular Weight: ≤3,000 Da
Source: Crab shell
Standard: Food grade
Overview
Chitosan Oligosaccharide (COS) Food Grade is a natural, biodegradable oligosaccharide derived from chitosan sourced from crustacean shells. With its low molecular weight, COS is highly water-soluble and widely used in the food industry for its beneficial properties, including acting as a prebiotic to support gut health, promoting fat metabolism, and enhancing nutrient absorption. It is a versatile ingredient in functional foods, dietary supplements, and weight management products, offering a natural solution for digestive health and overall well-being.
Key Features
- Lower Molecular Weight (<3000 Da) for enhanced bioavailability
- High Deacetylation Rate (≥90%)
- Excellent water solubility and absorption
- Compliant with food safety standards
