蜻蜓目的3种食用种类与营养价值

蜻蜓是分布广泛的昆虫 ,部分种类的稚虫可以食用。调查和研究成果表明 :在云南省的许多地方都有食用蜻蜓稚虫的习俗 ,常见的食用种类有红蜻、角突箭蜓、舟尾丝等 3种 ,其中含有蛋白质、脂肪、氨基酸、矿质元素等营养成分。它们的蛋白含量平均为 58.92 % ,脂肪含量平均为2 5.3 7% ,氨基酸含量平均为 4 6.0 3 % ,人体必需氨基酸含量平均为 16.4 1% ,占氨基酸总量的3 5.69% ,3种蜻蜓稚虫 K、Zn、Ca、Fe的平均含量分别为 2 960、12 5.4、2 616.6、796.2 mg· kg-1。由此可见 ,蜻蜓稚虫是营养丰富的食用昆虫资源

Three Edible Odonata Species and Their Nutritive Value

Dragonflise are common insects distributed widely.Parts of their larvae are edible.The research results showed that there is custom of eating dragonfly larvae in many places of Yunnan.The common edible species are Crocothemis servilia,Gomphus cuneatus and Lestes praemorsa.The larvae contain protein,fat,amino acids and microelements.The average contents of protein,fat and amino acids are 58.92%,25.37% and 46.03% respectively.The content of 8 kinds amino acids necessary for human body is 16.41% in average,which accounts for 35.69% of the total amount of amino acids.The content of potassium,zinc,calciun and ferrum are 2 960 mg·kg^-1,125 4 mg·kg^-1,2 616 9 mg·kg^-1 and 796 2 mg·kg^-1.Therefore the dragonfly larva is one of nutritive edible insect resources.
