中华豆芫菁成体的营养成分测定与分析

Determination and Analysis of Adult Nourishment Component of Epicauta chinensis

测定了中华豆芫菁Epicauta chinensis Laporte成虫的营养成分,共获得微量元素7种,其中以Zn和Fe的含量最高,在实验样品中的质量分数分别为0.038 28%和0.041 47%;脂肪中不饱和脂肪酸(P)/饱和脂肪酸(S)值为2.78,亚油酸和亚麻酸在脂肪酸中的质量分数分别为28.5%和36.2%;氨基酸在实验样品中的质量分数为50.15%,以谷氨酸质量分数最高,达到7.19%.由测定结果分析,中华豆芫菁具有明显的高蛋白、低脂肪和微量元素丰富的特点,其组成也比较特殊,可开发利用价值大.
