Decay, caused by Botrytis cinerea Pers., is the major problem of table grapes during cold storage. Preharvest and
postharvest applications are compulsory to avoid significant losses. Therefore, in this study, the efficacy of
applying ethanol gas generators to prevent storage decay was tested on cultivar of table grape, ‘Köhnü'. Ethanol
release pads were placed above the grapes in the modified atmosphere package. The grapes were stored for 60
days at 0±1 °C and determined after an additional 3 days at 20°C to shelf life. Samples were taken periodically
and investigated physical [soluble solid content (SSC), pH, weight loss, berry colour, stem dry (%), separated
rate, skeleton of cluster dry and decay rate (%)], chemical [titratable acidity, maturity index, phenolic
compounds] changes, sensory analysis and microorganism population. Results showed that ethanol release pads
treatments significantly decreased weight losses. Changes of the decay, skeleton of cluster dry and stem dry of
the grapes with ethanol release pads were delayed.
