太平洋牡蛎(Crassostrea Gias)的壳色是一种理想的特征，但不同壳色的太平洋牡蛎的营养研究尚未进行。通过连续选育，育成了黑色(B)、紫色(P)、橙色(O)、金色(G)和白色(W)等5个壳色品系。本研究的目的是评价5个壳色品系和1个具有相同颜色的商品群体的化学成分和营养价值。测定了水分、总蛋白、糖原、灰分、总脂肪、脂肪酸、氨基酸和矿物质等生化成分。结果表明，其主要成分为蛋白质(50.76%~56.57%)。橙壳品系与金壳品系、商品种群与金壳品系之间的糖原含量差异显著。此外，所有壳色菌株都含有大量的必需氨基酸(12.20~14.15g(100g)−1)，其中亮氨酸(2.81~3.29g(100g)−1)和赖氨酸(2.79~3.28g(100g)−1)是主要的氨基酸。牡蛎富含多不饱和脂肪酸(占总脂肪酸的42.26%~45.24%)，DHA(占总脂肪酸的18.53%~21.16%)和EPA(占总脂肪酸的17.23%~18.68%)含量较高。6个居群的矿物质(镁、锌、铁、铜)含量存在显著差异。这些结果表明，不同壳色的大银鱼具有丰富的营养价值，蛋白质、糖原、必需氨基酸和多不饱和脂肪酸含量较高。本研究获得的生化成分可用于选育不同壳色的长尾白对虾。
The shell color of Pacific oyster (Crassostrea gigas) is a desirable trait; but the nutritional studies on C. gigas with different shell colors have not been conducted. Through successive selective breeding, five shell color strains of black (B), purple (P), orange (O), golden (G) and white (W) C. gigas have been developed. 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. The biochemical composition including moisture, total protein, glycogen, ash, total fat, fatty acids (FA), amino acids and minerals was detected. The results indicated that the protein (50.76%–56.57%) was the major component. 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. 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 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). Significant differences of mineral contents (Mg, Zn, Fe and Cu) were identified among the six populations. These results indicated that C. gigas with different shell colors presented rich nutritional value with high protein, glycogen, essential amino acids and polyunsaturated fatty acids. The biochemical composition obtained in this study is useful for selective breeding of C. gigas with different shell colors.
