Effect of postharvest application of acetaldehyde vapour on strawberry decay, taste and certain volatiles.

Application of acetaldehyde (AA) vapour (1500-6000 micro l/litre) for 4 h, or at a constant concentration of 5000 micro l/litre for periods of 1 to 4 h, caused changes in the appearance and sensory quality of strawberries cv. Aliso. Some of these treatments induced rapid production of the volatiles ethanol, ethyl acetate and ethyl butyrate as found in the strawberry juice. Application of 5000 micro l AA/litre for only 1 h or of 1500 micro l AA/litre for 4 h induced the production of volatiles in modest amounts which increased fruit aroma and improved taste as determined by a taste panel. A longer period (3-4 h) of AA application of 3000-6000 micro l/litre caused off-flavours in the berries. Acetaldehyde treatments for 4 h reduced decay (mainly Botrytis cinerea infection) development during storage for 4 d at 5 deg C following 1 d at 20 deg .
