Abstract – Introduction. Postharvest physiology and ripening in passion fruit are not well
documented, which is an impediment in designing handling and storage regimes. Materials
and methods. Passion fruits harvested at four different maturity stages were studied for
postharvest ripening behaviour and to determine the correct stage of harvesting. Results and
discussion. The respiratory climacteric peak was attained in all stages irrespective of harvest
maturity, while the ethylene evolution rate increased by almost 8.15 times the initial value to
peak levels of 505.35 μL C2H4·kg–1·h–1 in fruits harvested at the 50% colour turning stage.
Changes in Hunter L*a*b* values indicated development of optimum colour only in fruits
harvested after 50% colour turning. Fruit quality attributes were also better in fruits harvested
after half (50%) colour turning than fruits harvested earlier. Conclusion. Passion fruit should
be harvested only after 50% of fruit surface colour has developed, so as to allow for optimum
postharvest storage, proper ripening, and development of characteristic flavour and fruit
quality attributes.
