Freeze-dried food

Freeze-dried food reference article on thruhikingwiki.com.

Overview

Freeze-dried food is dehydrated food created through a process that removes moisture while preserving texture and nutritional content. It is lightweight and commonly used in backpacking.

Key points

  • Extremely lightweight due to near-total moisture removal.
  • Long shelf life and easy rehydration with hot water.
  • Maintains nutrition and flavor better than some dehydrated foods.
  • More expensive than conventional meals.
  • Useful for long resupply intervals and remote routes.
  • Packaging can add bulk unless repackaged.

Details

Freeze-drying uses low temperatures and vacuum pressure to remove moisture from food while maintaining its structure and nutritional characteristics. This process results in very light, compact meals that require only hot water to rehydrate.

Popular among backpackers for convenience and calorie density, freeze-dried meals allow fast preparation with minimal cleanup. They often remain shelf-stable for years, making them suitable for long-term storage or extended trips.

However, freeze-dried food can be expensive and may involve bulky packaging unless repackaged into smaller containers. Its suitability depends on budget, resupply distance, and personal dietary preferences.
