Chitosan Food Grade bulk supplier & distributor

Chitosan Food Grade is a high-purity, biocompatible polysaccharide derived from the deacetylation of chitin. It is colorless to off-white, odorless, and highly soluble in dilute acidic solutions. With its excellent film-forming, chelating, and antimicrobial properties, food-grade chitosan is widely used in food preservation, dietary supplements, edible coatings, and functional food formulations.

This grade is specifically produced under stringent food safety standards, ensuring it is safe for human consumption while providing enhanced bioactivity, moisture retention, and shelf-life extension. Its versatility and natural origin make it a preferred ingredient in the food and beverage industry.
