Analysis and Evaluation of Nutritional Composition of Farmed Male Pufferfish (Takifugu Obscurus)
College of Food Science & Technology, Shanghai Ocean University, 201306 Shanghai, China
The nutritional compositions of the main tissues (meat, testis and liver) of farmed Takifugu obscures were investigated. All tissues reported in this study showed high amounts of crude protein in meat (18.44±0.11 g/100g) and testis (17.15±0.15 g/100g), but lower proportions in liver (3.89±0.16g/100g). At the same time, liver (63.86±0.93 g/100g) contained significant amounts of crude fat, while testis (1.82±0.13 g/100g) and meat (1.31±0.21 g/100g) contained lower proportion of crude fat. Concerning to the minerals, K was the most abundant macroelement in meat, testis and liver. At the same time, Zn accounts for the majority of microelement in meat and testis, while Fe does in liver. In addition, amino acids (AA) were rich in testis and meat. The contents of total amino acids (TAA) in meat and testis were 80.08 ±0.75g/100g and 63.33±0.10 g/100g, respectively. The ratios of total essential amino acids (TEAA) to TAA in meat and testis were 40.60% and 39.33%, respectively. The TEAA/TAAs were comparable to the reference values recommended by FAO/WHO. The AA contents of meat were dominated by Glu, testis were dominated by Arg. According to amino acid score (AAS), the first limiting amino acid of meat was Tyr; the first limiting amino acid of testis were (Phe+ Tyr).
