: Solidifying the water content rapidly to protect cellular structure. Primary Drying : Sublimation under a vacuum.
: For summer fruits like berries, lay them out on a tray to freeze individually before placing them in a bag to prevent them from sticking together. 4. Industry Applications
Freeze-drying, or , is a sophisticated method used to preserve high-value items while maintaining their original structure and nutrition. Freeze
: Used for stabilizing vaccines , proteins, and antibiotics.
: It removes water through sublimation —turning ice directly into vapor without it ever becoming liquid. Critical Phases : The process involves three main stages: : Solidifying the water content rapidly to protect
Freezing is the physical process where a substance transitions from a liquid to a solid.
: Whole tomatoes (for cooking), ginger, garlic, wine, nuts, and even pizza dough. : It removes water through sublimation —turning ice
: Avoid freezing mayonnaise, gelatin, or crumb toppings (like those on casseroles), as they often become soggy or separate upon thawing .
