I see. What kind of special preparation does space food undergo?
Space food is typically dehydrated or freeze-dried to remove moisture, which helps to increase its shelf life. It's also packaged in a way that prevents the growth of bacteria and other microbes that can spoil the food. Additionally, space food is designed to be easy to eat in zero gravity.
