precooling
Advance temperature reduction
Precooling is cooling something before a main process begins.
In agriculture, produce is precooled after harvest to slow spoilage before transport or storage: Precooling the strawberries extends their shelf life significantly.
Athletes may precool their bodies before competing in heat to improve performance.
The term appears in refrigeration and food science contexts.
