When the temperature gets near the triple digits and you’re cooling off with a chilled watermelon wedge, you should thank the hydrocooling method. What is hydrocooling? The method of hydrocooling is used to quickly chill produce post-harvest so it can get to your dinner table. Read on to learn more.

What is Hydrocooling?

Very simply, the method of hydrocooling is a way to rapidly cool produce by running near-freezing water over fruits and vegetables immediately after they are harvested. Without hydrocooling vegetables and fruits, once they have been harvested, the quality of the produce begins to decline, hence its shelf life. So how does hydrocooling work exactly?

How Does Hydrocooling Work?

Temperature and relative humidity begin to affect the
quality of produce immediately after being harvested. Heat may arise from field
temperatures or from natural respiration. Some farmers harvest at night to
combat field temperatures, but what about natural respiration?

Once produce is harvested, it is still alive and reacts to
oxygen to form carbon dioxide, water, and heat which begins the process of
breaking the produce down. This is called natural respiration. Harvesting at
night does nothing to stall natural respiration, which is where the
hydrocooling method comes in.

With hydrocooling, you are rapidly running chilled water
over the freshly picked fruit and veggies, quickly dropping their temperature
and eliminating tissue damage, thus extending shelf life. Water may be either
cooled with ice, a refrigeration system, or a hydrocooling system specifically
for hydrocooling produce.

During the process, the water is sanitized with one of a
variety of products. Hydrocooling is used to lower temperatures quickly but
cannot be used solely to cool and store produce. Instead, it is often used in
conjunction with forced air cooling or room cooling.

While there are a number of fruits and veggies that respond
well to the hydrocooling method, here are some of the more common ones:
