Harvesting & Storage
-
Bananas are harvested at various stages of its maturity depending upon the purpose
for which it is cultivated, such as culinary, table purpose etc., and distance to
the market (3/4 full maturity in Robusta for distant markets, while full maturity
for local market etc.).
-
In many of the perennial plantations, depending upon the time of setting of followers,
the age of follower sucker at the time of setting it, cultural practices like manuring,
irrigation followed will determine the time of harvest, and most often a continuous
harvest all throughout the year can be obtained.
Ripening
-
Bananas are not usually allowed to ripen on the tree as it takes long time. Moreover,
the fruit-peel splits, fruit ripens unevenly and fails to develop good colour and
aroma, hence the marketable quality deteriorates. Therefore, banana needs to be
ripened artificially.
-
On arrival at the destination, the banana bunches are immediately sold to wholesale
dealers who store the fruits in loose heaps in godowns and ripen them in lots as
per the need of the retail dealers.
- In tropical conditions, fruits for local consumption are harvested and ripened by
hanging the bunches in a shady place or a ripening hut.
- Smoke treatment is the commonest method to induce ripening in Maharashtra and Tamil
Nadu. Smoking is done with straw, leaves and cowdung in a closed chamber with bunches
arranged in a heap for 18-24 hours in summer and 48 hours in winter.
- After taking the bunches from the chamber they are placed in a well-ventilated room
for development of colour.

Ripening hut
|
-
Smoke treatment causes ripening of the bunches within 3 days. Ripening is also done
by keeping the bunches covered with gunny sacks.
-
Banana can be stored at a temperature slightly above 550 F (130
C) and a relative humidity of 85 to 95 per cent for about three weeks, and is ripened
in a week or two at 62-700 F (16.5-210 C).
-
Banana fruit becomes blackened at lower temperatures and should not be placed in
a refrigerator. Internally, the banana is carried either by rail or by road in unrefrigerated
carriage.
-
On the other hand, the produce for overseas trade is carried in refrigerated ships,
the banana being kept in a cool air circulation at about 52-560 F (11-13.50
C). Premature ripening is probably the biggest single cause of loss during storage.
-
Keeping the fruit in relatively high concentration of CO2 and low concentration
of O2 can prolong storage life.
-
Dipping of bananas at 200 ppm TBZ has been approved and recommended as a post-harvest
treatment.
-
A double coating of 12% wax emulsion prolonged the storage life of Dwarf Cavendish
banana by 10-12 days at 580 F (14.50 C).
Packing and transport
-
The banana bunches harvested at apt age of maturity are wrapped with dried banana
leaves before packing into in lorries or railway wagons for long distance transport.
This practice is in vogue in commercial orchards of Maharashtra, Bihar, etc.
