The recovery of protein hydrolysate during enzymatic isolation of chitin from shrimp Crangon crangon processing discards

摘要

Shell waste from shrimp Crangon crangon processing is a good source of chitin and proteins, contained on a dry basis of the offals in amounts 17.8/100 and 40.6/100, respectively. The digestion of the shells with proteolytic enzymes allow to recovery of the chitin and nutritionally valuable protein hydrolysate.
