METHOD FOR PRODUCING CHITOSAN WITH IMPROVED ANTIOXIDANT ACTIVITY AND ANTIBACTERIAL ACTIVITY

摘要

The present invention relates to a method for producing chitosan with enhanced anti-oxidation activity and anti-bacterial activity. Chitosan (g-chitosan) produced from ground crab shells has a lower ash content and a higher deacetylation degree, solubility, and viscosity compared to chitosan produced from whole crab sells and has an outstanding anti-oxidation activity and antibacterial activity, and thus can be provided as a proper material for antibacterial compositions or food.
