Description
A natural freeze-drying technique used by the Inca to preserve high-altitude crops.
Technical
The process involves freezing harvested produce at sub‑zero temperatures, then allowing ice to sublimate directly into vapor under low pressure and humidity. This removes water while preserving proteins, starches, and micronutrients, resulting in a lightweight, shelf‑stable product.
