Short exposures of red raspberry (Rubus idaeus L.) to high carbon dioxide and low oxygen at low temperature prevent postharvest grey mold (Botrytis cinerea Pers.).

Short exposures (1-3 d) of raspberries to high CO2 and low O2 atmospheres controlled the development of grey mould, caused by B. cinerea, during 2 or 3 d of storage at 20 deg C and 60% RH. CO2 at 84% and O2 at 3% maintained the level of decayed berries at between 0 and 7% during a 2 d storage period. The level of decay was between 19 and 29% when the berries were treated with 38% CO2 and 13.5% O2 during the same storage period. CO2 at 84% and O2 at 3% induced the development of off-flavours and odours which remained during the storage period. Raspberries treated with CO2 at 38% for 24 and 72 h maintained a fresh red colour for 1 to 2 d of storage but developed a slight off-flavour by the second day. The ascorbic acid content in berries decreased rapidly regardless of treatment.
