Ripening is a process in fruits that causes them to become edible. The fruit becomes sweeter, less green and softer.Ripening is associated with change in composition i.e. conversion of starch to sugar.However, all fruits do not ripen in the same manner.On the basis of their ripening behaviour, fruits are classified as Climacteric Fruits,Non-Climacteric Fruits.
There are several simple technologies and methods available today for farmers for proper ripening. Normally, the number of days taken for edible ripening varies for different fruits and prevailing climatic conditions. For instance, it takes about 5 to 6 days for mangoes and 6 to 7 days for sapotas to ripen. Under natural conditions, ethylene, a ripening hormone produced by the plant plays a major physiological role in the ripening process.
