| 摘 要： | 对天然生长的南极磷虾肌肉中营养成分与营养品质进行了较全面系统的分析,并结合安全性进行了初步研究。结果表明,南极磷虾肌肉(干样)中粗蛋白含量64·44%,粗脂肪含量5·14%,粗灰分含量10·90%,无氮浸出物含量19·52%;18种氨基酸总量为57·16%,其中8种人体必需氨基酸含量为25·88%,占氨基酸总量的45·25%;必需氨基酸指数(EAAI)为54·94,其构成比例符合FAD/WHO的标准;4种鲜味氨基酸含量为23·06%,占氨基酸总量的35·98%;矿物质含量丰富;铅、汞、镉、砷几种重金属含量平均值均低于相关食品卫生标准限量。综合分析认为,南极磷虾是一种食用安全、营养价值较高的虾类,具有良好的开发利用前景。

| Abstract: | The nutritional components of the flesh of Antarctic krill were tested and analyzed in order to evaluate its nutritive value and quality. The safety of Antarctic krill was also studied preliminarily. The results showed that the contents of crude protein, crude fat, crude ash and nitrogen-free extract (NFE) of the dry krill flesh were 64.44%,5.14%,10.90% and 19.52%,respectively. 18 common amino acids were found in the flesh, including 8 amino acids that are essential for human body. In dry samples, the total content of amino acids was 57.16%, and 25.88% for essential amino acids; therefore, the percentage of essential amino acids in total amino acids was 45.28%, and the essential amino acids index (EAAI) was 54.94. The content of four flavour amino acids was 23.06%in dry samples, making up 35.98%of total amino acids. The contents of trace elements were abundant and the average values of heavy metals (Pb, Hg, Cd and As) in the flesh of Antarctic krill were lower than the respective regulatory standards. In conclusion, Antarctic krill was found to be a safe edible shrimp of high nutritional value, which well deserves exploitation and utilization. |
