文中对皱纹盘鲍(Haliotis discus hannai)、杂色鲍(Haliotis diversicolor)、绿鲍(Haliotis fulgens)和杂交鲍4种不同品种鲍鱼肌肉中的一般营养成分、氨基酸、脂肪酸、无机盐及微量元素进行测定分析，并对其营养价值进行了评价。结果表明，4种鲍鱼肌肉蛋白含量在18.92%～21.63%，无显著差异(p>0.05)；4种鲍鱼脂肪含量均较低，在0.04%～0.09%，无显著差异(p>0.05)；总糖差异显著(p<0.05)，其中杂交鲍含量最高4.81%，皱纹盘鲍含量最低3.39%；氨基酸组成基本一致，共17种，氨基酸总量在16.24～18.12 g/100g，其中必需氨基酸8种，含量为4.78～5.08 g/100g，鲜味氨基酸与总氨基酸的比值(UAA/TAA)在43.35%～43.97%，胶原蛋白含量除杂色鲍(9.27%)外，其他3种在17.60%～17.96%。以氨基酸评分(AAS)和化学评分(CS)数据分析，杂交鲍营养价值高于其他3种。4种鲍鱼均含有丰富的棕榈酸、EPA和K、Ca、Zn等元素。因此，鲍鱼是一种高蛋白、低脂肪、营养价值高的优质海产品。

The nutritional compositions, amino acids, fatty acids, inorganic salts and trace elements from four kinds of abalone muscle (Haliotis discus hannai, Haliotis diversicolor, Haliotis fulgens and hybrid abalone) were analyzed and the nutritional values were evaluated.The results showed that there was no significant difference in protein contents from 4 kinds of abalone muscle(p>0.05), which were between 18.92% and 21.63%; there was no significant difference in fat between 0.04% and 0.09%(p>0.05).The contents of total sugar were significant difference(p>0.05), with the highest level of 4.81% in hybrid abalone and the lowest level of 3.39% in Haliotis discus hannai.The amino acid composition was basically the same with 17 kinds of amino acids and the total contents were between 16.24 g/100g and 18.12 g/100g, including 8 kinds of essential amino acid in the range of 4.78 g/100g to 5.08 g/100g.The ratios of flavor amino acid and total amino acid (UAA/TAA) were in the range of 43.35% to 43.97%.Collagen protein contents were between 17.60% to 17.96%, except abalone muscle from Haliotis diversicolor (9.27%).According to the amino acid score (AAS) and chemical score (CS) data analysis, the nutrition value of hybrid abalone is highest among 4 kinds of abalone.Four kinds of abalone are rich in palmitic acid, EPA and elements like K, Ca, Zn and so on.Therefore, abalone is a high-value seafood with high protein, low fat and high nutritional value.
