| 中文摘要: |
| 渔用饲料中一般都添加了着色剂、引诱剂、香精等，多数生产企业为了提高饲料的利用率，会加入饲用香精。用同时蒸馏萃取方法提取鱼饲料挥发性成分，可以为鱼料生产中饲料香精的调配提供初步的理论依据。同时蒸馏萃取（ＳｉｍｕｌｔａｎｅｏｕｓＤｉｓｔａｌｌａｔｉｏｎａｎｄＥｘｔｒａｃｔｉｏｎ，ＳＤＥ）是检测挥发性成分常用的方法。通过气－质联机分析，鉴定出５０种化合物，包括ｄ－柠檬烯（３０．１７％）、ｃｉｓ－２－甲基－５－甲基乙烯－２－环己烯－１－醇（５．２８％）、３，７－二甲基－１，６－辛二烯－３－醇（５．１３％）、ｔｒａｎｓ－氧化柠檬烯（４．８％）、丁酸乙酯（４．２３％）、３－甲基－１－丁醇（４．１０％）、亚油酸乙酯（３．５９％）、ｔｒａｎｓ－杨梅醛（３．３２％）等；其中，酯类及内酯类（２０种）、醇类（１１种）以及醛类（８种）为鱼饲料的奶香味兼果香味贡献较多。

| 英文摘要: |
| There are colourings, attractants, perfume and other additives in fish feed. Manufacturers may put feed perfume in fish feed in order to improve utilization. The aroma compounds of fish feed were analyzed using GC - MS. The results can provide theory of perfume mixing. Simultaneous Distallation and Extraction is a common method in aroma compounds detecting. 50 constituents could be identified using GC - MS, including D - Limonene （30. 17 % ）, 2 - methyl - 5 - （ 1 - methylethenyl） - cis - 2 - Cyclohexen - 1 - ol （5.28 % ）, 3,7 - dimethyl - 1,6 - Octadien - 3 - ol（5.13% ）, trans - Limonene oxide（4.8% ）, butanoic acid ethyl ester（4.23% ）, 3 - methyl - 1 - Butanol（4.10% ）, Linoleic acid ethyl ester（3.59% ）, trans - 3 - methyl - 3 - phenyl - oxiranecarboxylic acid ethyl ester（3.32% ） etc. Esters, laetones, alcohols and aldehydes make the most contributions to the milky and fruity of the fish feed. |
