Muscle and exoskeleton extracts analysis of both fresh and marine crustaceans Procambarus clarkii and Erugosquilla massavensis

Abstract

Both fresh and marine edible crustaceans Procambarus clarkii and Erugosquilla massavensis, respectively, are now important components of our local aquatic fauna in Egypt that have a small yet growing economic importance in our markets. So, the purpose of the present work was, therefore, to assess the protein, amino acids, fatty acids, minerals, vitamins, protein electrophoresis and dendrogram analysis of their extracts for the first time in Egypt which may be in the future play an important role in some pharmaceutical industries and may be used as a specific health foods (functional supplement). In the present study, nutritional analysis of muscle and exoskeleton extracts of P. clarkii and E. massavensis indicated the presence of a high amount of protein, 9 essential amino acids and 9 non essential amino acids including taurine which has a very scientifical action and benefit for men. Also, the results showed the presence of 9 unsaturated fatty acids which included essential fatty acids linoleic acid (Omega 6) and alpha linolenic acid (Omega 3) which have many functions for man (food supplement) in addition to 4 saturated fatty acids. The minerals recorded were Cu, Zn, Mn, Fe, Mg, Ca, K and P and the vitamins were Vitamims A, D, E, B 1 , B 2 , Bp, B 6 and B 12 . From the electrophoretic analysis of protein, the dendrogram analysis showed the highest similarity between the muscle and exoskeleton extracts of P. clarkii.

Assessment of Biochemical Compositions and Mineral Contents of Carapace of Some Important Commercially Crustaceans and Mollusks Organisms from Egyptian and Saudi Arabia Coasts as a New Animal Feed

“…This results ranked E. massavensis as the first rich edible crustaceans which drew the attention to the need of considering this protein rich crustaceans as good competitor among its economic counterparts in Mediterranean area. In this respect, many studies were done on the edible muscles of E. massavensis and indicated the presence of high amount of protein [4][5][6]28]. Nevertheless, the recorded values of carbohydrates, protein and lipid in the carapace of the mantis shrimps in the present study were less than those recorded in their edible muscles [5,6].…”

“…On the other hand limited studies were focused on the biochemical components of exoskeleton of marine organisms [6,[22][23][24]. However, the dried carapace can act as a rich constituent of poultry food [2, 4 ,22].…”

“…In this respect, many studies were done on the edible muscles of E. massavensis and indicated the presence of high amount of protein [4][5][6]28]. Nevertheless, the recorded values of carbohydrates, protein and lipid in the carapace of the mantis shrimps in the present study were less than those recorded in their edible muscles [5,6]. Furthermore, the present result demonstrate that the exoskeleton of males E. massavensis from two studied localities had higher percentage of protein than females.…”

“…The mantis shrimps E. massavensis which is a potentially an edible crustaceans that has growing economic importance in the area of the Suez Canal and in the Mediterranean Sea, the nature of its fishery is therefore, described as apart of the overall fishery of commercial crustaceans [4][5][6]. Additionally, E. massavensis is now important components of local aquatic fauna in Egypt that have a small yet growing importance in our markets [6]. Moreover, P. semisulcatus and M. monoceros are the main commercially exploited penaeid shrimps.…”

Evaluation of Nutritional Quality of Commercially Cultured Indian White Shrimp Penaeus indicus

“…The recorded data in the present study indicate the presence of 9 essential amino acids (arginine, histidine, lysine, threonine, methionine, leucine, isoleucine, valine and phenylalanine) and 7 non-essential amino acids (proline, tyrosine, glycine, alanine, serine, glutamic acid and aspartic acid). In aquaculture prawn Macrobrachium rosenbergii, nineteen amino acids were detected, among these eleven are essential and, eight are non-essential amino acids [7], while nine essential amino acids and nine non-essential were detected by [35] in edible muscles of Procambarus clarkii and Erugosquilla massavensis. The different amino acids in flesh of crustaceans species might be associated with the varying tastes as well as textural properties of meat of the crustaceans species [10].…”
