NASA developed this type of food for the astronauts: In order to further space exploration beyond near-Earth, NASA developed a means to harvest food in zero gravity, with very limited fertile soil and limited water supply.
So far, NASA’s advances in providing nourishing and tasty food for astronauts in space have led to many innovations in consumer food preservation, preparation and portability.
There is no solid salt or pepper, but there are in a liquid variant. Also, there is no bread for astronauts because of small bites that go flying around after a bite, instead of bread, there are tortillas. Also, the space food is usually hydrated because as there is no gravity affecting, the food just goes flying, so because of that, it’s hydrated to keep all the food together.
