This study describes chitosan extraction from shrimp wastes under different methods for evaluation their antibacterial activityChitosan were extracted from shrimp waste according to the conventional method. But in step of deprotenisation, three process acid, alkaline, and enzyme extraction was used. The extracted chitosan evaluated by inhibition of bacterial growth against foodborne pathogenic bacteria. Therefore, Escherichia coli and Staphylococcus aureus are used to study the antimicrobial activity. These results demonstrated that good results can be obtained by enzymatic and alkaline treatment. Subject to economic advantages, alkaline can replace the other methods
