What three preparation types define the current staple menu for astronauts in orbit?
Answer
Thermostabilized, irradiated, and rehydratable
The current operational menu for astronauts in space relies on food items prepared using specific preservation methods to ensure shelf stability and readiness for consumption. These three primary preparation types are thermostabilized items, which undergo heat treatment to inactivate microorganisms; irradiated items, which use radiation for preservation; and rehydratable meals, which require the addition of water by the crew before consumption. While these staples meet baseline needs, they often lack the nutritional complexity required for long-duration health and morale maintenance.
