采用常规的生化分析方法对南极帽贝软体部分的营养成分进行测定。结果表明:南极帽贝软体部分(干样)中粗蛋白含量为58.39%,粗脂肪含量为11.54%,灰分含量为9.97%;氨基酸总量为27.51%,必需氨基酸含量11.25%,占氨基酸总量的40.89%,第一限制氨基酸为缬氨酸,必需氨基酸指数为45.79;三种不饱和脂肪酸占脂肪酸总量的21.20%;矿质元素含量丰富。综合分析认为南极帽贝能为其捕食者如黑背鸥和企鹅提供优质的食物来源,同时也有一定的开发利用价值。 【英文摘要】 The limpet samples (Nacella concinna) were collected in the intertidal zone of Great Wall Bay, near the Great Wall Station, Antarctica, and analyzed by conventional biochemical methods. The result showed that the content of crude protein, lipid and ashes in the soft part (dry basis) was 58.39%, 11.54% and 9.97%, respectively. The content of the amino acids to the total dry weight of the soft part was 27.51%, in which the essential amino acids was 11.25%, accounting for 40.89 % of total amino acids.
