Pre-cooling

• Pre-cooling of the produce soon after their harvest (before storage/shipment) is one of the important components of the cool chain, which ultimately affect the shelf life of the produce.
• Rapid precooling to the products lowest safe temperature is most critical for crops with having high respiration rates
• First step in good temperature management

Purpose of precooling

➢remove the field heat from the produce.

➢To reduce moisture loss

➢To reduce ethylene production

➢To reduce respiration

➢Micro- organism

➢To increase shelf life
