Abstract
We evaluated the
efficacy of atmospheric modification in controlling decay and maintaining
quality of ‘Wonderful’ pomegranates kept at 5oC, 7.5oC or
10oC during the 1997-8 season using air, 2kPa O2, air +
10kPa CO2, and 2kPa O2 + 10kPa CO2. During the
1998-9 season we tested the following atmospheres at 5oC and 7.5oC:
air, 5kPa O2, air + 10kPa CO2, air + 15kPa CO2, 5kPa
O2 + 10kPa CO2, 5kPa O2 + 15kPa CO2.
We found that it is possible to store pomegranates at 7.5oC in 5 kPa
O2 + 15 kPa CO2 for up to 5 months, provided that the
level of latent fungal infections at the time of harvest is low and that the
pomegranates are sorted carefully after harvest to store only fruits that are
free from defects and decay.
CO2-enriched atmospheres resulted in
higher concentrations of acetaldehyde, ethanol, and ethyl acetate, especially
after 4 and 5 months of storage.
Accumulation of these volatiles was greater at
7.5oC than at 5oC, but in both cases the highest
concentrations were below the threshold values for detection of off-flavors.
