Abstract
The mud crab (Scylla sp.) belonging to Portunidae family has been aquacultured and used to provide a lot of nutrient foods and materials for supplementary food. Recent researches showed nutrient content of soft-shell crabs is higher than that of harden crabs. In this study, the content of total lipid and protein of Scylla sp. are found to be 1.2% and 30.5%, respectively. Additionally, trace elements contents (calcium and zink) were obtained of high level with 1.76% and 203.53 mg/kg, respectively. This is a potential source of materials for application in medicine and pharmaceutical industry in Vietnam. A enzymatic hydrolysis procedure was established as well in order to keep the high nutritional value of soft-shell crab materials. Based on these results, this procedure will be optimized as prospective in next step to obtain the maximized hydrolysate yield.
