Precooling and it's methods by Prof. Ganesh Shinde
 High temperatures are detrimental to keeping quality of fruits and vegetables, especially when harvesting is done during hot days.
 Pre-cooling is a means of removing the field heat. It slows down the rate of respiration, minimizes susceptibility to attack of micro- organisms, and reduces water loss.
