The only way is extreme compression. Even bacon will be pressed into small cubes by hydraulic press, and finally these bacon can only be called bacon cubes. From this point of view alone, space is not better than the earth, because in this weightless environment, everything will float in the air, just like a balloon full of hydrogen, including food and water, and some daily necessities, so it is impossible to live and cook in space like on earth.
In this weightless environment, it seems that we can only eat some fast food to fill our stomachs. The difference is that astronauts and scientists living in the International Space Station can now enjoy seasonal foods that are closer to the habits of the earth, such as candied fruit, cakes and even Christmas turkey dinner. Later, people built a kitchen on the space station. Do you know that?/You know what? The nutrition guarantee of space flight is the supply of energy first. Like the earth, it is still breakfast, lunch and dinner. At the same time, according to different flight times and astronauts' tasks, the recipes are arranged reasonably. It must be said that with the development of the space industry, astronauts' space meals are getting better and better.
It is reported that in 2005, Shenzhou VI astronauts had more than 50 kinds of food in their space recipes, including rice, eight-treasure rice, beef with dried tangerine peel, beef balls, cuttlefish, mushrooms and assorted vegetables. While eating, astronauts can also drink coffee, green tea or orange juice, as well as cream and thick soup. It is said to be more delicious than Yang Liwei.
For example, the diet of the "God 11" astronauts is a five-day cycle. In the later stage of flight, a low dietary fiber diet will be arranged appropriately to increase the supplement of compound nutrients. Ground personnel will record the astronauts' diet, evaluate it regularly, and remind them what to eat and how much to eat when necessary. At that time, astronauts Jing Haipeng and Chen Dong will perform the longest 33-day space stay mission in China's history. According to the scheduled plan, God XI will fly for 2 days and then go to Tiangong-2. "God" will fly together for 30 days. During this period, astronauts will carry out space science experiments and applied technology experiments, as well as popular science activities in Tiangong-2. In the autonomous flight segment of Shenzhou XI, astronauts may have poor appetite, so they will be equipped with light food such as porridge.
After officially entering Tiangong-2, astronauts can enjoy three meals a day, just like at home. Their meal time is synchronized with the ground, including staple food, non-staple food, ready-to-eat, drinks, condiments and functional foods. There are traditional dishes such as beef with sauce and shredded pork with fish flavor, and the menu will not be repeated for five days. It is understood that the ground expedition team distributed six categories of staple food and non-staple food to astronauts during this period.
100 A variety of foods, as well as baked goods similar to desserts. Considering the changes of astronauts' physical condition during the mid-flight period, some foods also have dietotherapy effects. People combine the concepts of dietotherapy and nourishing in China's medicine to prepare corresponding food, so that astronauts can have better physique to finish their work. In general, the shelf life of space foods is above 1 year, and they contain no preservatives, which is not only safe and reliable, but also very safe.
Researchers need to use food engineering technology to better preserve and package food. In order to let astronauts eat hot meals, Tiangong-2 is also equipped with a special food heater, which astronauts can use to heat. By the way, astronauts' space meals not only have delicious dishes, but also desserts.
For astronauts living in the International Space Station, nutrition is undoubtedly the most important thing in their diet, and weightlessness will weaken people's taste, so mustard, Chili sauce, mayonnaise and other "heavy taste" seasonings are very popular among astronauts. In fact, as long as the nutrition and storage conditions are met, some healthy foods can go into space, such as Indian curry fish and crab patties, which are deeply loved by astronauts, and even pizza can be put on the spacecraft. Generally speaking, since space food can be used,
First of all, we must meet the safety requirements, provide sufficient energy and nutrition, and at the same time conform to the astronauts' eating habits as much as possible in order to be delicious. For example, many foods are not fresh but dry. In fact, this time astronauts can also eat ice cream in space, but unlike the ice cream with water on the earth, they eat freeze-dried ice cream, which is as dry and hard as the white foam they usually see. When eaten in their mouths, it tastes good, and the energy has reached the food of astronauts.
Some people say that dessert, as a daily necessity for westerners, cannot be absent from the space menu. Nutritionists sent chocolate pudding, lemon jam cake and apricot pie into space to meet the calorie and taste needs of astronauts. Astronauts can also eat birthday cakes on their birthdays. See if the friends here want to go to heaven, too?
