Semi-Manual Processing Of Blood Clamps Waste into Chitosan Powder

Blood clams (Anadara granosa) are endemic found in Southeast Asia and East Asia. widely consumed by the public as seafood dishes coastal food stalls. The great potential of blood will increase waste clam shells produced. accumulation shellfish cause pollution reduce environmental aesthetics. chitin content can be used chitosan. Chitosan is a polymer -(1-4) glucosamine which formed when acetyl group substituted hydrogen to become an amine group. has antibacterial antifungal properties. Isolation chitosan was carried out through stages demineralization, deproteination, deacetylation. limited use laboratories during pandemic major obstacle isolation process This study aims shell into simple way on home scale. Processing includes deacetylation were done using tools materials available at home. Laboratory equipment such beakers could replaced with pots, reflux cloth filter, measuring cups glasses. research 1500 grams powder produced 1050 white slightly hard texture
