摘要: 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.

Abstract: Adult nourishment component of Epicauta chinensis was determined in this research, in total it contains 7 kinds of trace elements,and Zn and Fe reached 0.038 28% and 0.041 47% respectively in experimentation sample. The proportion of unsaturated fatty acid(P) and saturated fatty acid(S) is 2.78,the content of C_(18:2) and C_(18:3) in fatty acid is the 28.5% and 36.2% respectively, the content of amino acid in experimentation sample is 50.15%,the content of Glu is the highest,reached 7.19%. Analysed result showed that E. chinensis contained high protein,low fat and abundant trace elements.

Key words: Epicauta chinensis, nutrient, protein, fat, trace elements
