| 【目的】探寻大帛斑蝶幼虫和蛹的主要营养成分，评价它们的营养水平，为大帛斑蝶的食用开发提供理论基础。【方法】选择大帛斑蝶4龄中期幼虫和悬挂约2 d的新蛹为试验材料，测定其水分、粗脂肪、灰分、蛋白质、矿质元素、氨基酸的含量，分析大帛斑蝶幼虫和蛹的氨基酸分、必需氨基酸指数，并与常见食物(猪肉、牛肉、鸡肉)进行比较分析。【结果】大帛斑蝶幼虫和蛹的蛋白质含量分别为59.1%和66.4%，脂肪含量分别为8.30%和10.8%，其无机物质含量丰富、矿质元素含量高、能量低；大帛斑蝶幼虫和蛹的总氨基酸含量分别为353.6和331.1 mg/g，必需氨基酸总含量分别为123.0和131.4 mg/g，必需氨基酸占总氨基酸的比例分别为34.8%和39.7%，必需氨基酸与非必需氨基酸的比值分别为53%和66%，必需氨基酸指数分别为0.807和0.641。【结论】大帛斑蝶幼虫具有较高的营养价值和食用开发价值，可作为蛋白质源，但大帛斑蝶蛹氨基酸整体结构不够平衡。 |

| Abstract: |
| 【Objective】This study explored the main nutritional ingredients of Idea leuconoe larva and pupa to provide a theoretical basis for the edible development of I.leuconoe larva and pupa.【Method】 Selecting 4 instar larvae and new pupa pupated for about 2 d of I.leuconoe as materials,the contents of water,fat,protein,mineral elements and amino acids were determined.The amino acid scores and essential amino acid indexes were analyzed and the components were compared with those of pork,beef and chicken.【Result】I.leuconoe larva and pupa had abundant mineral elements and low energy.The contents of fat,protein,total amino acids,total essential amino acids,ratios of essential amino acids,ratios of essential amino acids to non essential amino acids,and essential amino acid indexes of larva and pupa were 8.30% and 10.8%,59.1% and 66.4%,353.6 and 331.1 mg/g,123.0 and 131.4 mg/g,34.8% and 39.7%,53% and 66%,and 0.807 and 0.641,respectively.【Conclusion】I.leuconoe larvae had high nutritional value and edible value as a protein source,while the amino acid structure of I.leuconoe pupa was unbalanced. |
