Mangoes can be ripened either at the markets or onfarm
using ethylene. Using the ‘shot system’ ethylene
is injected at 200 ppm twice in 24 hours. Ventilate
the room for 10 minutes between shots to remove
the build-up of carbon dioxide. Keep the humidity
above 85% to reduce moisture loss from fruit. The
best ripening temperature is 18 to 22o
C. Temperature
control is important for full flavour and skin colour
development, so avoid temperatures above 24o
C.
Mangoes will be ripe for eating in 5 to 9 days.
