Chitosan is a well known biopolymer with applications in various areas, and especially in pharmaceutical and medical fields. The main source of chitosan is represented by the marine waste. The present study was focused on chitosan extraction from shrimp waste using a classical chemical procedure. The obtained chitosan was characterized regarding its physical-chemical properties,and also the antioxidant activity and hemolytic activity were evaluated. In this study, the chitosan samples were dissolved in diluted solutions of acetic acid and lactic acid. The results showed that the best antioxidant activity was obtained for the chitosan dissolved in acetic acid. Also, the chitosan samples produced significant effects on the red blood cells activity. All these results suggest that new potential applications could be envisaged.
