The spoilage of freshmeat ismostly caused by the presence of volatile organic compounds (VOCs) of microbial origin that are responsible for off-odors. The volatile fraction of the microbial catabolites includes: organic acids, volatile fatty acids, ethyl esters, sulfur compounds, ketones, aldehydes, alcohols, ammonia and other molecules. A list of VOCs detected inmeat during storage in different packaging conditions and when LAB were inoculated or identified as possible spoilers is reported in Table 1
