At this specific temperature and pressure, typically the ice crystals within the food go into water vapor, bypassing water's liquid form, through a new process called sublimation.
This process preserves the cell structure in addition to nutritional content of the food, ensuing in a product or service that, when rehydrated, very closely resembles the original food.
