Nutrient Retention Study
A comprehensive study on nutrient retention in freeze-dried foods compared to other preservation methods showed the following results:
| Nutrient | Freeze Drying | Air Drying | Spray Drying |
|---|---|---|---|
| Vitamin C | 92% | 55% | 78% |
| Vitamin B1 | 95% | 72% | 85% |
| Flavonoids | 88% | 60% | 75% |
| Antioxidants | 90% | 65% | 80% |
Freeze drying consistently achieves the highest nutrient retention across all measured parameters.
