Precooling Is Essential for Many Types of Produce


After harvesting, it’s essential to properly cool produce in order to maximize its shelf life. By staving off the natural growth of microorganisms, the cooling process helps to slow the physiological changes which impact freshness and nutritional value. This can be achieved both through lower-cost and more advanced methods, including harvesting during cooler periods during the day, cool air ventilation, and evaporative cooling. For many types of produce, however, precooling is an essential part of the equation. Precooling is a process performed to rapidly remove field heat immediately following a harvest. Field heat is described as the difference between the…
