Mango Ripening
Usually ethrel spraying or dipping of fruits in ethrel was recommended for enhancing ripening, but it is a cumbersome process, and may cause some problems if commercially available ethrel is with chemical impurities. To overcome this, ethylene gas has been commercially used in modern ripening chambers, which require huge investments and are not economically viable option for farmers and small traders. An alternative, simple economical method has been standardized for enhancing ripening of fruits by exposing fruits to ethylene gas in the plastic tents, In this, small quantity of alkali ia added to ethrel to release ethylene gas, and fruits are exposed to liberated gas in an air-tight portable plastic tent. Fruits are placed in the ventilated plastic crates inside the air-tight tents of known volume. Required/ calculated quantity of ethrel in a container is placed inside the tent to which measured quantity of alkali (sodium hydroxide) is added for releasing ethylene gas; and the tents are sealed air-tight immediately. A small battery operated fan can be placed inside the tent for uniform circulation of released ethylene gas. After 18-24 hours of exposure, fruits are taken out for completion of ripening process at the room temperature. Mango fruits exposed to 100 ppm ethylene gas for 24 hours could ripen in 5 days as compared to the ripening in 10 days of the non-treated control fruits; without adversely affecting quality.
