Description
Dehydration removes water to inhibit microbial growth and extend shelf life.
Technical
Freeze‑drying (lyophilization) sublimates ice under vacuum, preserving structure and flavor; spray drying atomizes a liquid into hot air, producing powders with rapid moisture removal; sun‑drying relies on ambient heat and low humidity, but is vulnerable to oxidation and contamination.
