Color as a harvest index for cherimoya Traditionally cherimollas are harvested by size and colour for local and export market. As the first shipments for export had some quality and condition problems at the international market arrival, it was necessary to check the colour using an objective method in order to establish the right colour for harvest. The condition was mainly affected by an inhibition of the normal ripening, it means no softening and flavour development.

The objective of this investigation was to determinate the colour evolution (using an colorimeter) during growing, maturation and different harvest times to evaluate the postharvest behaviour of thefruit after a ripening period of 6 days at 18°C.

Fruits were market early in the season, between 4 and 5 months before potential harvest; size and colour were measured every month using a sizer and a Minolta colorimeter. At harvest firmness, soluble solids, pH and titratable acidity were measured as well. The cherimoyas were kept at 18°C for 6 days.
