title: Lime treatment of shrimp head waste for the generation of highly digestible animal feed.
abstract: In addition to approximately 20% ash, shrimp processing by-products contain 64% protein and chitin, both of which can be used to generate several valuable products. Chitin and chitosan production is currently based on several crustacean wastes, and at the present time the protein fraction is not being used. This paper describes the thermo-chemical treatment of shrimp processing wastes with lime to generate a protein-rich material with a well-balanced amino acid content that can be used as a monogastric animal feed supplement. The residual solid, rich in calcium carbonate and chitin, can still be used to generate chitin and chitosan through well-established processes.
