Amino acid composition and nutritional quality of gonad from jellyfish Rhopilema esculentum

摘要

In the present study, amino acid compositions of two jellyfish gonad samples were determined and the nutritional value was evaluated by the amino acid score method recommend by WHO/FAO and fuzzy recognition method. The two samples were abundant in amino acids. The major amino acids were both glutamic acid, lysine, glycine, aspartic acid and leucine and the contents of these amino acids were 51.47% and 52.52% of the total amino acids, respectively. The essential amino acids were 42.89% and 40.70%, the flavor amino acids were 47.39% and 50.12% and the medicinal amino acids were 66.55% and 66.92% of the total amino acids, respectively. μ (a, μi) values of the two samples were respectively 0.91 and 0.94 and SRC values were respectively 70.89 and 69.96, indicating that the essential amino acids of jellyfish gonad were well-balanced and the nutritional value of jellyfish gonad was high.
