摘要
对乳山刺参体壁和内脏的基本营养成分,包括水分、蛋白质、脂肪、灰分、海参糖胺聚糖、海参皂苷、脂肪酸组成、氨基酸组成以及16种无机元素含量进行了系统测定和比较分析。结果表明,在刺参体壁和内脏中,水分、粗蛋白、粗脂肪、灰分、海参糖胺聚糖和海参皂苷含量分别为90.67%、76.11%;49.75%、34.90%;6.56%、5.15%;27.50%、36.85%;7.47%、1.08%;0.062 2%、0.017 4%。体壁和内脏中含有21种脂肪酸,内脏中多不饱和脂肪酸含量高于体壁,含EPA 13.09%、DHA 6.88%。二者粗蛋白的氨基酸组成中,必需氨基酸占氨基酸总量的39.36%、39.93%,谷氨酸和天冬氨酸等鲜味氨基酸[19.07,11.57 g/(100 g)]以及精氨酸等药效氨基酸[10.78,7.06 g/(100 g)]含量较高。无机元素含量高,富含镁、铁、锌、钒、硒等元素,内脏中钒和锰的含量尤为丰富。研究表明,刺参内脏亦含有丰富的蛋白质、多不饱和脂肪酸和钒、锰、硒等无机元素,具有较好的食用和药用价值,应得到充分利用。
The content of moisture,crude protein,crude fat,ash,glycosaminoglycans,saponin,the composition of fatty acids and amino acids and 16 kinds of elements were comparatively analyzed in body wall and internal organs of sea cucumber Apostichopus japonicus collected at Rushan.The results showed that the contents of moisture,crude protein,crude fat,ash,glycosaminoglycans and saponin averaged 90.67%,76.11%;49.75%,34.90%;6.56%,5.15%;27.50%,36.85%;7.47%,1.08%;0.062 2%,0.017 4%;respectively.21 kinds of fatty acids were found in both body wall and internal organs.Internal organs have more PUFAs,the EPA and DHA were the predominate fatty acids,accounting for 13.09% and 6.88%.Thirteen kinds of amino acids were detected in both body wall and internal organs,including 8 kinds of essential amino acids which accounted for 39.36%,39.93% of total amino acids.The two parts were both rich in flavor amino acids[19.07,11.57 g/（100 g）]such as glutamic acid（Glu）,aspartic acid（Asp）and efficacy amino acids[10.78,7.06 g/（100 g）]such as argine acid（Arg）.The AAS and CS of the essential amino acids of the internal organs were lower than those of body wall.Both parts are rich in minerals,especially elements Mg,Fe,Zn,V,Se.The contents of V and Mn in the internal organs are particularly rich.The internal organs of sea cucumber A.japonicus are the potential material for diet and medicine,which should be fully utilized.
