美洲大蠊的营养价值与饲用安全性的分析

Nutritive values and feeding safety of Periplaneta americana L.

摘要: 对美洲大蠊的常规营养成分、矿物元素、氨基酸、脂肪酸及卫生指标进行测定,并与秘鲁鱼粉进行比较分析,结果表明:美洲大蠊粗蛋白质和粗脂肪含量分别为63.1%和17.20%;含有18种氨基酸,属于完全蛋白质,且必需氨基酸与总氨基酸的比例为37.95%;美洲大蠊虫体中还含有丰富的矿物元素;不饱和脂肪酸以油酸为主,饱和脂肪酸以棕榈酸为主;主要卫生指标含量均低于饲料卫生标准中的安全限量,表明美洲大蠊可作为一种优质的功能性蛋白饲料。

Abstract: The nutritional content and sanitary indexes of Periplaneta americana L.were determined.The results showed that crude protein and fat in P.americana L.was 63.1% and 17.20%,respectively.There were 18 kinds of amino acids.The ratio of essential to total amino acid was 37.95%.It was rich in minerals.The dominant unsaturated fatty acid was oleic,and saturated fatty acid palmitic.The contents of Pb,As,Cd,Cr,mould fungus and bacteria were within the limit of safety.Therefore,P.americana L.could potentially be used as a material for high quality feed.
