In this paper, the nutriments and amino acids composition of the enzymolytic protein powder of Trachurus japonicus were studied. Results showed that the powder had a high content of crude protein content (66.37%) and was in rich of tasty amino acids, such as Glutamic acid (7.97%),Aspartic acid (5.81%) and Glycine(4.66%). According to the suggested level of FAO/WHO(1973), the protein powder showed high nutrient value due to the high amino acid score (82) and threonine being of the first limiting amino acid. Besides, the powder was rich in inorganic salts, especially Ca and Zn.
