The design principle of space food

On the afternoon of June 11, Shenzhou 10 was launched successfully. Because the Dragon Boat Festival is on the 12th, astronauts eat rice dumplings with bean paste in space, which once again attracts people's attention to space food. Today, Xiaobian will show you what astronauts eat in the sky?

It is understood that the early space food is paste food, such as apple sauce, beef sauce, vegetable paste and meat vegetable mixture. The paste food is packed in plastic bags. One end of the bag is provided with a feeding tube. The plastic bag is squeezed by hand, and the food is squeezed into the mouth through the feeding tube. In addition to pasty food, there are also "rehydrated" food and "stuttered" food that can only be eaten with water.

According to the astronauts, the paste food tastes bad. The "rehydrated" food is not easy to soften after adding water, and the food packaged like toothpaste is "hard to swallow". While the "stuttered" food will spray a lot of debris in the process of eating, which will not only contaminate the surrounding instruments and equipment, but also may be inhaled into the lungs, causing serious consequences.

Since then, space food has been greatly improved, with a large increase in varieties and patterns. There are more than 80 kinds of food and drinks on the astronaut's menu. Chinese astronauts also have rich food, in addition to a wide variety of fish, canned meat, bread, and other Chinese dishes, which are more colorful, fragrant and beautiful than western food.

Because Chinese astronauts love tea, they are also equipped with iced black tea, green tea and other fashionable modern drinks. In addition, the researchers prepared strawberries, apples, bananas, peaches and other fruits for the astronauts. In order to facilitate the preservation, they removed water at low temperature and processed them into freeze-dried fruits. Although the fruit has become a 'dry fruit', it has a good taste and color. And the freeze-dried ice cream is also unique. This kind of ice cream is white and solid, with cream taste.

The most attractive food this time is the bean paste zongzi. Because yesterday was the Dragon Boat Festival. Although astronauts could not get together with their families on the ground, they might eat Zongzi with their teammates in space that day.

In addition, the three astronauts will also take the space drinking water, which can be directly drunk and can last for 12 months at room temperature.

It seems that the astronauts are eating pretty well.
