刺参不同部位中主要营养成分分析与评价

本文对刺参不同部位(体肇、肠和卵)中的主要营养成分进行了研究.结果表明:刺参属于高蛋白质食品,且肠和卵的蛋白质含量高于体壁;富含人体所必需的铜、铁、锰、锌等元素,这些元素更易在肠中富集;δ-维生素E在刺参中含量丰富,以肠中最高;体壁中酸性粘多糖含量较高,为5.03%;氨基酸组成全面,鲜昧氨基酸的含量丰富,体壁中羟脯氨酸含量很高,为4.20%,是动物胶原蛋白的主要成分;鉴定出23种脂肪酸,必需脂肪酸含量高,尤其C20:5 n3(EPA)在肠中高达16.06%.因此.刺参具有较高的营养价值和一定的药用价值.动物营养学报,2010,22(1):212-220]中文全文见<动物营养学报>网站(www.china.JAN.com)中文版2010年22卷1期]

Analysis and Evaluation of Chief Nutrient Composition in Different Parts of Stichopus japonicus

Nutritive and functional composition in different parts (body wall, intestine and spawn) of Stichopus japonicus were investigated in this paper. The results were shown as follows: Stichopus japonicus was of high protein and the content of protein in the intestine and spawn were higher than those in body wall; Cu, Fe, Mn, Zn and other metal elements were abundant, which were more likely enrichment in the intestine; the content of δ-VE was high, especially in the intestine; the percentage content of acid mucopolysaccharide in the body wall was high and the content was 5. 03% ; composition of amino acids was complete, and free amino acids (FAA) were rich. Hydroxyproline which was the basis of collagen protein accoun-ted for 4. 20% in the body wall; there were 23 kinds of fatty acids were detected and it was found that the essential fatty acids content was high, especially the content of C20 : 5 n3 (EPA; was 16. 06% in the intestine. In conclusion, Stichopus japonicus was of high nutrition value and some officinal value.
