乳山刺参体壁和内脏营养成分比较分析

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。
