Aerospace foods are essentially the same as common foods on the ground. They all provide energy and nutrition to the human body. In order to save space in the spacecraft and payload during launch, the spacecraft carried by the spacecraft must be lightweight, compact, nutritious, and free of debris.
Early space foods were paste-like foods. Scientists mixed all kinds of food needed by people to make a paste and packaged it with toothpaste plastic. When you eat, squeeze the plastic tube by hand and the food can be squeezed into the mouth. In addition to paste foods, there are rehydration foods and "a bite" food. However, the astronauts felt that the texture of the paste-like food was not good; the rehydration food was not easy to soften after adding water; the toothpaste-like packaging was uncomfortable; the “stuttered†food would blew a lot of debris during the process of eating, not only Dirty instruments and equipment may also be inhaled into the lungs, causing serious consequences.

At present, there are more than 80 kinds, such as ham, beef, lemon pudding, jellies, small snacks, fruit juices, etc., their moisture content and the food they eat on the ground. the same. If it is on the International Space Station, there are frozen foods, frozen foods, seasonings, etc. At the same time, recipes can also be formulated based on the astronauts’ own eating habits.
Our astronaut’s food is also quite abundant, with more than 20 kinds of foods to choose from.
