This experiment was carried out to investigate a simple method of modified atmosphere storage for maintaining freshness of bananas and avocados by unglazed pottery (pot) at room temperature. Pots had comparatively high gas permeability with easy realization of a seal. By the features of pots and respiratory activity of fruits, low O2/high CO2 were maintained in pots. Those levels were 14 kPa O2+5 kPa CO2 for bananas, and 3 kPa O2+ 14 kPa CO2 for avocados. Moreover, ethylene production was inhibited at high CO2 levels, and relative humidity (RH) was about 90%, as desired in the pots. This observed result was considered to have been due to the fact that RH was relative to osmosis of the pots and transpiration of fruits. It was found that freshness retention of tropical and subtropical fruits at room temperature can be obtained through changes of RH and gas compositions in the pots, and therefore, as a storage technique, pots can be applied for storage of fruits.
