The storage under controlled atmosphere at lower O2
and higher CO2 levels was effective to minimize the quality
losses of yellow passion fruits and to extend their postharvest
life. The reduction in O2 levels to less than 5% preserved the
vitamin C content, but it increased the total soluble sugars
and dropped the titratable acidity content during the 30 days
of storage. These effects were impaired by increasing the CO2
levels. The best atmosphere composition was defined at 5% O2
and 15% CO2, after the fruits removal from the chamber and
storage for 9 days in cold room, when the fruits presented the
same chemical compositions compared to those stored under
normal atmosphere.
