摘　　要：蛹肽蛋白是蚕蛹粉经微生物发酵后的产物。对蚕蛹粉和蛹肽蛋白的气味物质、氨基酸组成、金属元素含量进行测定分析的结果表明：蛹肽蛋白中有3种臭味化学物质的含量显著低于蚕蛹粉（P〈0.05）;与蚕蛹粉相比,蛹肽蛋白的氨基酸组成除谷氨酸含量降低和蛋氨酸含量升高外,其余组分无明显变化（P〉0.05）;蚕蛹粉和蛹肽蛋白的重金属含量均未超标,且蛹肽蛋白中铬元素（Cr）的含量降低。将蛹肽蛋白添加于罗非鱼（Tilapia mossambica）的饲料（质量分数为5%、10%的添加量）和凡纳滨对虾（Litopenaeus vannamei）的饲料（质量分数为10%的添加量）进行养殖试验,发现适量蛹肽蛋白可显著促进仔罗非鱼和凡纳滨对虾生长,降低饲料系数（P〈0.05）。研究结果显示蛹肽蛋白在水产动物饲料领域具有较大的应用潜力。The silkworm（ Bombyx mori） pupa peptides are produced from microbial fermentation of silkworm pupa powder. In this study,the odor,amino acid composition and metal element content of silkworm pupa powder and silkworm pupa peptides were determined. It was found that three odor chemicals in silkworm pupa peptides were significantly lower than those in silkworm pupa powder（ P〈0. 05）. Their amino acid composition had no obvious change except for the decrease of glutamic acid and the increase of methionine in silkworm pupa peptides（ P〈0. 05）. The contents of all heavy metals had no obvious change and chromium（ Cr） in silkworm pupa peptides was lower than that in silkworm pupa powder. After adding silkworm pupa peptides into fodders to raise Tilapia mossambica（5% and 10% mass fraction）and Litopenaeus vannamei（10% mass fraction）,it was found that suitable addition of silkworm pupa peptides could promote the growth and reduce the feed coefficient of T. mossambica and L. vannamei（ P〈0. 05）. These results indicate that silkworm pupa peptides in application are good additive for aquafeed development.
