摘要: 对海地瓜进行营养成分测定,包括对海地瓜中主要营养组分、氨基酸组成、脂肪酸组成和矿物质元素的测定、分析和比较,并对其营养价值进行分析和评价。结果显示,海地瓜体壁中粗蛋白、粗脂肪、多糖和粗灰分的含量分别为81.22%、0.23%、3.62%和10.33%;羟脯氨酸含量达31.2 mg/g;18种氨基酸的总量为80.08%(干重),其中8种必需氨基酸占总氨基酸的23.95%,鲜味氨基酸占总氨基酸的54.48%,必需氨基酸与非必需氨基酸的比值为0.31,必需氨基酸指数为57.03,必需氨基酸的构成比例低于FAO/WHO的标准;不饱和脂肪酸(UFA)占脂肪酸总量的55.1%;矿物质元素中钙含量最高,为4 100 mg/kg。结果表明,海地瓜是一种有低脂高蛋白的海洋生物资源。

Abstract: Nutritional components in body of Acaudina molpadioides were analyzed and nutritive quality were evaluated. The results showed that the contents of crude protein, crude fat, polysaccharose and crude ash of dry body of Acaudina molpadioides were 81.22%, 0.23%, 3.62% and 10.33%, respectively. Hydroxyproline content was up to 31.2 mg/g. In dry samples, the total content of 18 kinds of amino acids was 80.08%, among which essential amino acids and delicious amino acids accounted for 23.95% and 54.48%, respectively. The ratio of essential amino acids to non-essential amino acids was 31%. The essential amino acid index (EAAI) was 57.03. It was apparent that the constitutional rate of the essential amino acids was lower than the FAO/WHO standard. The unsaturated fatty acids accounted for 55.1% of the total fatty acids. Calcium (Ca) was the most predominant mineral element and its content was 4 100 mg/kg. In conclusion,Acaudina molpadioidea is a valuable marine biology resource with low fat, rich in protein and mineral elements.
