Résumé

In a simulation of commercial practices, grapes were fumigated once a week and aerated for 30 min while stored at 0 deg C for at least 14 consecutive weeks. The maximum residue levels at each dose level were observed between the seventh and eleventh weekly fumigations. The influence of post fumigation temperature on sulfite residue loss was minor and inconsistent. These data suggest that current industry practices leave sulfite residues well below the official legal tolerance.
