Definition: These are powders made by removing the moisture from citrus fruits (or parts of them, like the peel) and grinding the dehydrated material into a fine or coarse powder.
Types: Can come from whole fruit, pulp, or peel (zest). Many commercial citrus powders are made from the peels, which are rich in flavor and nutrients.
Drying Methods: The dehydration can be done using hot-air drying (traditional dehydration), freeze-drying, or spray-drying.
Stabilization: Because powders can be hygroscopic (absorb moisture), they are often dried properly and sometimes packed under inert conditions (e.g., nitrogen) to prevent clumping.
