Refrigerated storage is a vital component of agricultural technology that reduces postharvest food waste by slowing the biological processes that lead to deterioration. Because harvested fruits and vegetables remain living organisms, they continue to undergo metabolic changes that can result in softening, decay, and loss of quality.12
Refrigeration helps mitigate this waste through several key mechanisms:
- Slowing Life Processes: Lowering temperatures retards the natural deterioration that begins immediately after harvest, including respiration and enzymatic activity that lead to tissue breakdown.324
- Inhibiting Decay: Cold temperatures slow the growth of decay-causing organisms, extending the shelf life of produce.4
- Reducing Water Loss: By controlling temperature and humidity, refrigeration helps prevent wilting and dehydration, maintaining the produce's physical integrity.14
- Precooling: Rapidly removing field heat through methods like hydrocooling or vacuum cooling ensures that produce reaches the consumer at maximum quality, further minimizing losses during transit and storage.54
By stabilizing these perishable goods, refrigeration allows for better market distribution and helps ensure that food remains edible for longer periods.2
