Odors emitted from food processing plants are becoming more of a concern as food plants and residential areas grow closer in proximity. The objectionable odours in the food industry are generally a result of the physical processing of foods in which biological or chemical reactions form volatile organic compounds (VOC). These reactions are often precipitated by such processes as heating, drying, or smoking of foods. Odour thresholds are subjective among neighbours of processing plants and for this reason standard methods have been approved for testing odours.
Most odourous compounds emitted from food plants are not a public health concern but can be considered a public nuisance and, therefore, are subject to local governmental regulations.
