Analysis of human body odor components adhered to clothes, and the influence which an unpleasant odor has on comfortable sensation.

本研究采用气相色谱-质谱联用技术和热脱附系统对衣服上附着的人体气味成分进行了分析。此外，我们还研究了体味成分对人体的影响。睡衣或枕套检出50余种，醛类化合物（正辛醛、正壬醛、反式-2-壬醛、正癸醛）呈暂时性升高。在嗅觉感官评价中，中老年男性比年轻男性感受到自身体味的强度和油性，这些与醛类成分的产生有关。皮肤表面检出的细菌以表皮葡萄球菌居多。

In this study, we analyzed human body odor components adhered to clothes by gas chromatography-mass spectrometry (GC/MS) and the thermal desorption system. Furthermore, we investigated the influence that the body odor components gave to a body. More than 50 kinds were detected by night clothes or pillowcases, and the aldehyde compounds ( n-octanal, n-nonanal, trans-2-nonenal, n-decanal ) increased temporally. In the olfactory sensory evaluation, the old and middle aged men felt strength and oily of own body odor than younger men, these are associated with the aldehyde components production. As for the bacteria detected in the skin surface, the most of then were Staphylococcus epidermidis.
