A volatile organic compound (VOC) analysis method has been developed to distinguish human remains from animal species in forensic cases and to identify the species of remains after disaster accidents.
Seven animal species, plus human, were investigated. Some VOCs had high species specificity, demonstrating that all tested muscle tissue samples could be distinguished based on different VOCs. HS-GC-IMS proved to be a rapid, high-throughput, high-sensitivity and specific species identification method. The authors propose that the technique could also be applied to food authenticity testing to verify meat species.
