Alternatives to sulphur dioxide in table grape storage: potentials for ethanol vapours.
Experiments have been conducted over three years to optimise the application of ethanol vapours in order to prevent Botrytis development and stem browning, two of the major problems in postharvest quality of table grape.Various strategies have been tested: modified atmosphere packaging, several concentrations of ethanol in the vapour phase, combination of sulphur dioxide or modified atmosphere with ethanol.Results show that small doses of ethanol alone (around 2 ml per kg of grapes) gave a sufficient control of Botrytis development to replace SO2, without a concomitant increase in stem browning.Other results, e.g. berry shatter and consumer acceptability, will be discussed.
