Rapid cooling of fresh produce immediately after harvest is vital for conserving the quality, freshness and extending the shelf life of fruits and vegetables.

This technique is known as pre-cooling or field heat removal and forms an integral part of an effective cold chain management system.

Pre-cooling helps reduce the field heat significantly which is a residual heat present in fresh produce even after harvest due to respiration and other metabolic activity.

The main objectives behind pre-cooling are to minimise water loss, slow down degradation, and curtail microbial growth.

There are traditional as well as advanced methods to perform the rapid cooling process including room cooling, forced-air cooling, hydrocooling, and vacuum cooling.

Room cooling is the simplest method where fresh produce is placed in a cold-stored room till it achieves the desired temperature.

However, this method might not be highly efficient for large volumes due to poor air circulation.

Forced-air cooling involves the use of fans to circulate cold air around the produce that enhances the rate of heat removal.

With hydrocooling, water is used as a medium to remove field heat due to water’s high heat-carrying capacity as it is virtually 25 times greater than air.

Vacuum cooling works faster but is relatively expensive compared to other methods, it is mainly used for leafy vegetables and mushrooms whose high surface area allows for rapid evaporation.

Proper implementation of rapid cooling methods not only ensures good quality produce for the end consumers but also significantly cuts down food wastage due to spoilage.

The choice of pre-cooling methods mainly depends on the type of produce, its volume, and the available resources.

Regardless of the method used, it is very important to ensure that the required temperature is reached as quickly as possible and is maintained properly without fluctuations.
