In 2004, the gasses released during
decomposition began to be catalogued by the
University of Tennessee Anthropological Research Facility. An experiment bottled and stored decomposing flesh from various bodies of animals and humans, keeping all remains in identical conditions. While this study provided useful information, researchers recognized that it is far from being used in direct training of dogs to find human bodies. These factors would suggest that findings from inside the controlled lab with artificial conditions are far from creating an exact profile of what should be present/absent when identifying the organic compounds which signify a "death scent" as human. To introduce the volatile organic compounds or VOC, they use a "
body farm" to monitor an environment of the variables. The other body farm doing VOC research to identify or confirm results is outside the US, The Australian Facility for Taphonomic Experimental Research. ==Synthetic production for training==
