This paper investigated the components, especially aldehydes, in the fume condensates from four kinds of cooking oil using ultraviolet (UV) spectrometry and gas chromatography-mass spectrometry (GC-MS). It was observed that there was a great change of the UV absorption spectra from the results of the unheated oil to the results of the fume after heat treatment (190-200, 230-240, and 270-280 degrees C). There was a strong peak within the wavelength range of 260-270 nm in each condensate sample. From the GC-MS results, it was tentatively deduced that there were some 2,4-dialkylenaldehydes and other conjugated compounds in the condensates. The results showed there were large amounts of hexanal and 2-heptenal in the cooking oil fume and that the total aldehyde peak areas of the condensates from four kinds of oil were around 30-50% of the total peak area at 270-280 degrees C.
本文采用紫外光谱法和气相色谱-质谱联用（GC-MS）法研究了四种食用油油烟冷凝物中的成分，尤其是醛类物质。研究发现，从未加热油的结果到热处理（190 - 200、230 - 240和270 - 280摄氏度）后油烟的结果，紫外吸收光谱发生了很大变化。每个冷凝物样品在260 - 270纳米波长范围内都有一个强峰。从GC-MS结果初步推断，冷凝物中存在一些2,4 - 二亚烷基醛和其他共轭化合物。结果表明，食用油油烟中含有大量己醛和2 - 庚烯醛，四种油的冷凝物中总醛峰面积在270 - 280摄氏度时约占总峰面积的30 - 50%。
