A STUDY ON THE TREATMENT METHODS FOR SHRIMP’S SHELLS TO COLLECT NATURAL COMPOUNDS HAVING BIOACTIVITY

Abstract

Nowadays, untreated shell shrimps and fish viscera reasonably are able to become the main sources leading to the environmental pollution in the fishery factories. This report describes the results of the investigation into the chemical components from shells of giant tiger shrimps (Penaeus monodon) and shells of white leg shrimps (Penaeus vannamei) collected from Danang City, Vietnam. Based on the properties of the chemical components from shrimp’s shells, we extracted two natural compounds having bioactivities, including carotenoid which can be used for food products and chitin containing minerals and protein that are lower than 0.5% for each. The applications of protease extracted from fish viscera can reduce more than 75% protein from shrimp’s shells in the manufacturing chitin,; besides it can decrease the amount of used stock acids compared with the traditional methods.
