Research Progress in Methods for Human Body Odor Analysis
Human odor is an important pheromone with a wide range of applications in various fields such as forensic science,disaster relief,disease diagnosis,and even cosmetic research and development.In the field of forensic science,the identification of volatile organic compounds(VOCs)in human odor is of great significance in determining the direction of investigation and the search for corpses.Due to the com-plex components of human odor,it is necessary to collect human odor with media to make human odor samples,and then use highly sensitive instruments for further analysis.Samples often need to be pre-served before analysis.By summarizing the relevant literature in recent years,the collection,preservation and detection methods commonly used to examine human odor are outlined.Among them,the collection methods include contact and non-contact collection,the preservation methods mainly focus on the type of container and the preservation temperature and other conditions,and the detection methods cover a varie-ty of techniques such as gas chromatography and electronic nose.Finally,the future development direc-tion of human odor analysis is prospected,aiming to provide a reference for the court science field to car-ry out the applications of human odor to detect cases and other related research.
