: Avoid freezing mayonnaise, gelatin, or crumb toppings (like those on casseroles), as they often become soggy or separate upon thawing .

: It removes water through sublimation —turning ice directly into vapor without it ever becoming liquid. Critical Phases : The process involves three main stages: Freeze

: Used for stabilizing vaccines , proteins, and antibiotics. : Avoid freezing mayonnaise, gelatin, or crumb toppings

: Unique among most substances, water expands when it freezes, which can lead to practical issues like frozen and burst water pipes . 2. Freeze-Drying Technology : Avoid freezing mayonnaise

: Preserving plasma and medical samples for research.

Beyond home use, freezing and freeze-drying are vital to several major industries:

: Solidifying the water content rapidly to protect cellular structure. Primary Drying : Sublimation under a vacuum.
