Extension of postharvest life of 'Mission' figs by CO2-enriched atmospheres.

Good quality of fresh Mission figs was maintained for up to 4 weeks when kept at 0 deg , 2.2 deg or 5 deg C in atmospheres enriched with 15 or 20% CO2. The visible benefits of exposure to high CO2 levels were a reduction of the incidence of decay and the maintenance of a bright external appearance. Ethylene production was lower, and fruit softening (as measured with a deformation tester) was slower in figs stored at high CO2 concentrations than in those kept in air. Ethanol content of the CO2-treated fruits increased slightly during the first 3 weeks and moderately during the 4th week, while acetaldehyde concentration increased during the first week, then decreased. It is concluded that the postharvest life of fresh Mission figs can be extended by 2-3 weeks by holding them at 0-5 deg in atmospheres enriched with 15-20% CO2 but off-flavours can be a problem by the 4th week of storage.
