Résumé

Gas and water vapour permeabilities (WVTR) of 7 coatings, used commercially on citrus fruits, were determined by coating these onto plastic films on known permeability. In addition, oranges and mandarins were dipped in the same 7 coatings and stored at 15 deg C and 60% relative humidity up to 26 days. Accumulation of ethanol and acetaldehyde was attributed to the creation of partial anaerobic conditions and the barrier properties of the coatings to these compounds. There was also a relationship between WVTR and weight loss of the fruits with most coatings, but no correlation between CO2 and O2 permeability of the coatings and concentrations of these gases in the fruits.
