Beyond Dehydration
Freeze drying is fundamentally different from heat drying. Instead of applying heat to evaporate water, freeze drying sublimates ice directly to vapor under vacuum โ preserving cellular structure, nutrients, and flavor that would be destroyed by heat.
Pet Food Applications
The premium pet food market has embraced freeze drying for:
- Raw complete diets โ freeze-dried raw patties and chunks retain nutrient profiles without refrigeration
- Single-ingredient treats โ chicken breast, beef liver, fish fillets โ pure protein with no additives
- Meal toppers โ freeze-dried crumbles add flavor and nutrition to kibble
