Abstract

The present study highlights the nutritional value of three commercial shrimps; the green tiger prawn Penaeus semisulcatus (De Haan, 1844), the kuruma prawn Penaeus (Marsupenaeus) japonicus (Bate, 1888) and the ginger prawn Metapenaeus monoceros. (Fabricus, 1798) collected along the western Mediterranean coast of Egypt. The results show that the percentage of protein of the three studied shrimps was the main constituent where female and male Marsupenaeus japonicus had the greatest protein percentage (51.37% and 50.12%, respectively). The highest lipid value was documented in female Marsupenaeus japonicus (13.01%) while the highest carbohydrate percentage was recorded in male Penaeus semisulcatus (3.1%). Nine essential amino acids which are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine and valine were identified. Arginine recorded the highest average concentration. Three non-essential amino acids were detected, that are aspartic acid, glutamic acid and glycine. Vitamins B1 and B2 were detected in both sexes. Analysis of minerals showed the presence of four minerals (Ca, K, Na and P). P recorded the highest mineral concentrations in Marsupenaeus japonicus, Metapenaeus monoceros and Penaeus semisulcatus. Concerning the results of this study that focused on the nutritional value of three commercially important shrimps, it is recommended to be consumed by human as a good source of protein, arginine, vitamins B1 and B2, phosphorus and calcium. In conclusion, this comparative study revealed that the kuruma prawn Marsupenaeus japonicus has the best nutritive value among the studied shrimps.
