Mangoes are susceptible to physical damage at virtually every part of the
postharvest handling chain, and reduction/elimination of physical/mechanical
injury is essential to reduce losses in quality and in postharvest life (Yahia, 2005).
Even green mangoes can fracture internally if dropped from a height during
the harvest operation. Careful transport from the fi eld is necessary to avoid
additional injury. Packinghouse handling allows washing plus better selection
and packing according to size compared to other handling and packing systems.
Strong shipping containers with internal dividers help protect mangoes from
damage during loading, shipping, and unloading operations, and as the fruit ripen
and soften. The types of physical damage that may occur to mangoes include
scuffi ng, along with compression, vibration, and impact bruising (Yahia, 2005).
Scuffi ng occurs when fruit surfaces are abraded by stems of other fruit, the sides
of rough or dirty picking containers, dirty packing line conveyors and worn or
stiff packing line brushes. Mangoes can also develop scuffi ng when vibration in
transit allows individual fruit to rub against each other. Dropping, compression
and vibration cause bruising to the fl esh of mango fruit, which shows up internally
as discoloured, water-soaked areas. Ripe fruit are more susceptible to bruising
and
thus require better packaging. Mechanical injury can be the cause of
several other problems, including the increase of respiration rate and ethylene
production, increasing the loss of water, facilitating the attack and penetration of
disease causal agents, etc. The reduction/elimination of mechanical injury is
essential to reduce losses in quality and in postharvest life.
