Controlled Atmospheres (CA) Consideration
Modified atmospheres (MA) have been tested on yellow
passion fruit, with a fungicide treatment applied before
storage is desirable. Fruit held at 6 to 10°C (43 to 50°F)
for 3 to 4 weeks had less shrivel (Campbell and Knight
1983). Film-bagging and various coatings reduce water
loss in yellow and purple passion fruit (Mohammed
1993, Arjona et al. 1992). Response to film bagging may
be associated with control of water loss, rather than MA
effects. A carnauba- or paraffin-based coating or wax
is sometimes applied before packing of purple passion
fruit to increase fruit gloss, reduce water loss, and extend
postharvest life. The wax is applied by spraying, with
brushes, or by rubbing.
