摘要
[目的]分析测定了玻璃海鞘的营养成分,并对其营养价值进行了评价。[方法]采用常规方法测定了水分、脂肪、蛋白质、灰分、氨基酸、脂肪酸和矿物质含量。[结果]玻璃海鞘水分、脂肪、蛋白质和灰分分别为:93.08%、2.08%、1.99%和2.7%。共检测了16种氨基酸,其中甘氨酸含量最高,必需氨基酸占总氨基酸的比值为42.51%,必需氨基酸和非必需氨基酸的比值为73.94%。测定了玻璃海鞘中13种脂肪酸,其中饱和脂肪酸8种,单不饱和脂肪酸2种,多不饱和脂肪酸3种,多不饱和脂肪酸含量占脂肪酸总量的13.8%。玻璃海鞘中含有丰富的Fe、Zn、Mn、Cu、N i等微量元素,对重金属等有毒有害物质分析结果表明其均符合国家相关安全卫生标准。[结论]玻璃海鞘营养价值较高,具有较好的开发前景。
[Objective] The research aimed to analyze the nutritional components in Ciona intestinalis and evaluate their nutritional value.[Method] The contents of moisture,fat,protein,and ash amino acids,fatty acids and minerals in Ciona intestinalis were determined by conventional methods.[Result] The contents of moisture,fat,protein and ash in Ciona intestinalis were 93.08%,2.08%,1.99% and 2.7%,respectively.16 kinds of common amino acids in Ciona intestinalis were determined,among which glycine content was the highest,and the ratios of total essential amino acids to total amino acids and to non-essentialamino acids were 42.51% and 73.94%,respectively.18 kinds of common fatty acids were measured in Ciona intestinalis,including 8 saturated fatty acids,3 non-unsaturated fatty acids and 3 poly unsaturated fatty acids.The contents of poly unsaturated fatty acids in fatty acids were 13.8%.Fe,Zn,Mn,Cu,Ni and other elements were rich in Ciona intestinals.The detection and analysis of heavy metal elements and other toxic substances in Ciona intestinalis indicated that they met national safety and health standards.[Conclusion] Ciona intestinalis possess high nutritional value and promising prospects for further development.
