Cold Chain Best Practices

Cold Chain Integrity

A successful cold chain requires temperature control at every step from harvest to consumer. Key principles include:

• Rapid initial cooling: Field heat must be removed within 2-4 hours of harvest using vacuum pre-cooling or forced-air cooling
• Temperature monitoring: IoT-enabled data loggers should track temperature at every transfer point
• Cold storage: Maintain consistent temperature (0-4°C for produce, -18°C for frozen) with minimal door openings
• Transport: Pre-cooled reefers with real-time GPS temperature tracking

Studies show that each break in the cold chain reduces shelf life by 30-50%.
