lyophilized
Frozen then vacuumed
Lyophilized means freeze-dried—preserved by freezing and then removing moisture through vacuum sublimation.
The process keeps biological materials stable for storage and transport: lyophilized vaccines, lyophilized plasma.
Pharmaceutical and laboratory contexts favor this technical term over the more familiar "freeze-dried."
