After harvesting the fruits are graded according to size shape maturity and freedom from diseases and blemishes The cut surface is treated with a suitable fungicide to control fungal decay

Storage
When fruits are transported for long distances or to be stored for several days refrigerated transport is required to slow down ripening process In tropical areas partially ripe healthy and unbruised pineapple could be stored for almost 20 days when refrigerated at 10130C with RH 8590 Fruits harvested in early stage of ripening are stored at 710C Exposure of pineapples to temperatures below 7C results in chilling injury Controlled atmosphere storage 35 O2 and 58 CO2 delayed senescence and reduced respiration
