The SO2 injury was not detected by the panelists. With
other treatments, the taste of berries was rated as unacceptable
(≤5) after 3 months, but the appearance remained acceptable (>5)
for only 2 months. Moreover, the panelists did not detect an alcoholic
flavor in ‘Red Globe’ grapes treated with ethanol vapor even
though ethanol residues were found in high doses.
