Abstract:
Food-processing gaseous effluents are rich in flavoured volatile organic compounds (FVOCs). The discharge of these FVOCs is unwanted as they can contribute to the environmental olfactive pollution.Their recovery would then enable their valuation through the strengthening of the organoleptic properties of the finished products or their use in other products, as well as reducing the pollution linked to their discharge. However, there are only a few documents in the literature concerning food aromas recovery from gaseous effluents. This paper reviews the used or potential technologies for the recovery of aromas from gaseous effluents in the food-processing industry.The technologies that are already applied in the food processing industry for aroma recovery from gaseous effluents are the vapour permeation and the condensation. The adsorption and the absorption are technologies used for scrubbing volatile organic compounds, which can be potentially used for gaseous aroma recovery.
