Fresh Produce Shelf Life Studies
February 1, 2026
Study Overview
Multiple studies have compared the effectiveness of vacuum cooling versus forced-air cooling for extending the shelf life of fresh produce. Key findings from a recent study on leafy greens:
| Parameter | Vacuum Cooling | Forced-Air Cooling |
|---|---|---|
| Cooling time (25°C → 2°C) | 20-30 min | 3-6 hours |
| Weight loss | 1.5-2.0% | 3-5% |
| Shelf life extension | 40-70% | 20-30% |
| Uniformity (±°C) | ±1°C | ±3°C |
The study concluded that vacuum cooling significantly outperforms forced-air cooling in all key metrics.
