- 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.
Peas and okra which deteriorate fast need prompt pre-cooling.
pre-cooling methods -
1. Room cooling,
2. Forced air cooling,
3. Water cooling,
4. Vacuum cooling
5. Package icing.
