| Abstract | ||||
| The present study was planned to investigate the effect of three techniques; traditional, microwave and autoclave on properties and economic evaluation for chitosan obtained from shrimp shell waste. Results showed that sun dried Suez-shrimp wastes composed (wet weight) 5.28% moisture, 7.09% (total nitrogen), 7.77% lipid and 36.15ash content. Microwave technique improved the water binding capacity (WBC) property and antioxidant propertieswhereas traditional technique improved the oil binding capacity (OBC) property. Also, there are variation in degree of deacetylation (DDA) values; 95.5% for autoclaved, 93.0 for microwaved and 88.5 for traditional chitosan samples. Economically, the traditional method is the best economic methods. Also, it provides about 45.7 thousand pounds/ton and it reduces the chances of imported chitosan and modifies of the Egyptian trade balance. In conclusion, this study recommends that shrimp shells waste should be utilized to produce chitosan as an economic and value added product and to encourage local production and reduce imported chitosan. | ||||
