Headspace gas analysis for short chain hydrocarbons (pentane and ethane) is proposed as a tracer for following the oxidative degradation during storage of foods contained in sealed containers. This type of analysis could be used for foods ranging from oils and emulsions to frozen meats and dehydrated cereals. Correlation between sensory and analytical evaluation must be established for each individual product. Headspace gas analysis of a great variety of products was conducted and very good correlation between sensory and chemical analysis was obtained.
