Consumers’ willingness to pay for the color of salmon: A choice experiment with real economic incentives. gigas with different shell colors.Īlfnes, F., Guttormsen, A. The biochemical composition obtained in this study is useful for selective breeding of C. gigas with different shell colors presented rich nutritional value with high protein, glycogen, essential amino acids and polyunsaturated fatty acids. Significant differences of mineral contents (Mg, Zn, Fe and Cu) were identified among the six populations.
The oysters were rich in polyunsaturated fatty acids (42.26%–45.24% of total fatty acid) with high levels of DHA (18.53%–21.16% of total fatty acid) and EPA (17.23%–18.68% of total fatty acid). In addition, all shell color strains contained a large amount of essential amino acids (12.20–14.15 g (100 g) −1), of them leucine (2.81–3.29 g (100 g) −1) and lysine (2.79–3.28 g (100 g) −1) were predominant. The content of glycogen showed a significant difference between orange shell and golden shell strains, as well as between commercial population and golden shell strain. The results indicated that the protein (50.76%–56.57%) was the major component. The biochemical composition including moisture, total protein, glycogen, ash, total fat, fatty acids (FA), amino acids and minerals was detected. The aim of this study was to evaluate the chemical composition and nutritional value of five shell color strains and one commercial population with a common color.
Through successive selective breeding, five shell color strains of black (B), purple (P), orange (O), golden (G) and white (W) C. gigas with different shell colors have not been conducted. The shell color of Pacific oyster ( Crassostrea gigas) is a desirable trait but the nutritional studies on C.
