Space meals are very abundant, what foods can t astronauts eat?

Astronauts can eat a variety of delicacies in space, such as sausage pies, spicy grilled fish, roast beef with potatoes, brioche bread, tempeh broth, tuna salad, biscuits, chocolate, yogurt, preserved fruits, fruit juices, and even Coca-Cola, which they love. However, astronauts are not allowed to eat whatever they want, and all diets must be strictly controlled by a ground nutritionist.

Bread, biscuits, salt, chili, pepper and other condiments, carbonated drinks, these things are not eaten by astronauts in space, because the use of condiments in space will cause pollution to space.

For example, instant noodles, milk, sausages, eggs, and tomatoes are not edible. Because this food can't be stored in space at all.

Bread, carbonated drinks, fresh milk, barbecue, hot pot. There are several kinds of food that astronauts cannot eat.

In the early days, astronauts ate various nutrient solutions in outer space, similar to toothpaste-like food, packaged in aluminum tubes, and made into minced meat, jam, etc. After development, astronauts can eat dehydrated freeze-dried food, rice, noodles, various dishes, fruits and vegetables, and add water to make a paste and eat. Now, astronauts can eat a variety of delicacies such as Sichuan cuisine and eight-treasure rice in space.

In order to save space on the spacecraft, astronauts must carry space food that is as lightweight, small, nutritious and debris-free as possible. The food must meet the requirements for physiological changes in astronauts under weightlessness conditions. Therefore, food should be aimed at the changes in human metabolism and physiological functions that may be caused by the weightless environment, including proteins, fats and various trace elements in food.

Although China's manned space missions are not long, and the changes in the physiological state of astronauts do not have high requirements for food ingredients, they are all designed for long-term flights.

Recently, a "astronaut's space meal, what is the difference between it and an ordinary meal?" The question sparked heated discussions among the majority of netizens, and it caused a stir on the Internet. So, what is the difference between an astronaut's space meal and a regular meal?

First, space meals tend to be more nutritionally balanced and richer to prevent astronauts' physical problems. Second, foodShelf lifeIt is often longer, and the food will go through more processing processes, which is not only nutritious, but also healthy and high-quality. Thirdly, it usually comes with a heavier flavor.

Because when they go to space, their sense of taste will weaken, and many things will taste weaker. So what's going on? Let me share my thoughts with you.

One. More comprehensive nutritionFirst of all, there is a need for more comprehensive nutrition. Because they must have comprehensive nutrition in space, so that their bodies can be kept in the best condition, and there can be no nutritional deficiencies. The calorie intake will also be relatively high. <>

Two. Longer shelf lifeSecondly, their food will have a longer shelf life. Because they have to work on it for a long time, the food has to have a long enough shelf life, and if it goes bad, then they will starve to death in space, which is a very dangerous thing. <>

Three. Last, their space meals tend to come with packets of chili, ketchup, mustard and so on. Because when they go to space, their sense of taste will deteriorate, and they will feel that there is not much taste when they eat ordinary, so they will make themselves "heavy".

The above is my opinion on this issue, which is purely personal and for reference only. If you have any different opinions, you can leave a message in the comment area and discuss it together. After reading it, remember to like and follow.

Compared with ordinary meals, it is even worse, and it is all paste-based food, small lumpy compressed food, and meltwater food. Pulp foods include vegetable leaf pulp, pork pulp, apple pulp, etc., and small block compressed foods are mostly compressed biscuits, compressed dried meat, etc.

Compared with ordinary meals, space meals are very different and must be traitive, because they are eaten in a space environment, so they are very different from ordinary meals.

Space food is essentially the same as ordinary food on the ground, providing energy and nutrients for the human body. In order to save space and payload at launch, the spacecraft must carry space food that is lightweight, small, nutritious, and free of residues.

The astronauts' diet is also very particular, most of the food they carry is special food, the food has little water content, but it is rich in a variety of nutrients, and the shape is mostly cuboidal, small in size, and light in weight.

Due to the special weightless environment in space, it is impossible for astronauts to eat normally and easily like people living on Earth. There are certain peculiarities in the nutrition, preparation and ** of space food, as well as the way of eating astronauts. When humans first went into space in the 60s of the 20th century, due to technical limitations and safety concerns, astronauts were only given paste-like semi-fluid food, which they squeezed in their mouths like toothpaste.

The first in the United States"Toothpaste"It's applesauce, and in Russia it's cabbage soup.

But in weightlessness, astronauts can't shed enough saliva, and their sense of taste is dull, so toothpaste-like food seriously affects their appetite. With the advancement of science and technology, space food has been greatly improved. At present, there are many types of aerospace food, which are divided into different categories such as staple food, non-staple food, ready-to-eat food, beverages, condiments, and functional foods.

Each country has also developed special food for its astronauts to send into space. In the case of China's Tiangong-2, astronauts on the space station can eat it"Normal"meals, three times a day. Breakfast includes porridge, rice cakes, braised eggs, cabbage and mango juice.

Both lunch and dinner are equipped with 2 main courses, 3 dishes, a side dish, a canned fruit, and a soup. These dishes include snow cabbage rabbit, pine nut corn, braised bamboo shoots in oil, shredded pork with fish flavor, spicy peanuts, beef in sauce, and more.

Due to weightlessness, astronauts' muscles are prone to atrophy, such as fish-flavored shredded pork, sauced beef and other foods are rich in protein, which can promote the synthesis of body muscles, and these foods taste very good, and can also promote astronauts' appetite. In addition to the main meal, astronauts can eat more snacks, including almonds, chocolate, cookies, chicken wings, yogurt and even ice cream. , beverages, freeze-dried beverage mixtures (coffee or tea) or flavored beverages (lemonade or orange juice) in vacuum-sealed beverage bags.

Coffee and tea can be sweetened with cream powder or sugar depending on personal taste. There will also be empty drink bags for drinking water. Fresh food, fresh fruits, vegetables and tortillas on cargo ships.

These foods spoil quickly and need to be consumed within two days of arrival. These foods can provide psychological support to astronauts on long-term missions, irradiate meat and canned food, sterilize it with ionizing radiation, and prevent spoilage. Semi-dry foods, which have some moisture but not enough to cause immediate spoilage, such as sausages and beef jerky.

Ordinary foods, foods sold in supermarkets, such as nuts, crackers, and cereal bars, can be eaten as is.

eat porridge, rice cakes, braised egg rolls and mango juice in space; Their food is only a mushy semi-fluid food that is squeezed in their mouths like toothpaste, but now the astronauts' food has improved and normal meals can be eaten.

There is almost no difference between the food they eat and the earth, such as biscuits, chocolate, bread, and sausages, but the nutritional value is relatively high, and the things they eat are generally prepared in advance by nutritionists. Nutritionally balanced, so far, there are about 100 kinds of food.

The things they eat are not very different from those on the ground, such as biscuits, bread, ham sausages, and then there are more fresh fruits and vegetables, and there will be room for food preservation, and they have eaten mapo tofu rice bowls in space before.

They usually eat some fruits or some compressed biscuits in space, and the food they eat is special, and these foods can overcome environmental problems.

There are about 100 kinds of food that astronauts eat in space, including bread, chocolate, beef, milk, sausages, preserved fruits, juices and other foods. Astronauts generally eat 4 meals a day, and the recipes are not repeated during the week. The food that astronauts eat is not ordinary vegetables and fruits, they are specially processed compressed bricks or toothpaste tubes, which can be restored to their original shape after adding a certain percentage of water.

Space food has a high nutritional value, but they must follow the recipe prepared for them by a ground nutritionist.

Space food is generally dehydrated food, and before eating, you need to put the food in a container, fill a certain amount of water into the container with a syringe, and then put it in the oven to heat.

Astronauts should not talk while eating, because talking while eating will cause the crumbs of food to fly out of their mouths and float in the dining room or living module, and the astronauts will easily choke into their lungs if they are not careful to inhale into their noses.

Astronauts can eat biscuits, chocolate, yogurt, preserved fruits, bread, beef, sausages and much more in space. The astronauts' recipes were prepared for them by nutritionists on the ground, and at first there were only a dozen kinds of food, but later they grew to more than 100.

In space, objects are in a state of weightlessness, and in order not to affect flight safety, astronauts generally choose food without droplets when the food they eat is ruined.

The full name of an astronaut is "astronaut", which refers to a person who takes space flight as a profession or has carried out space flight, with a special working environment, highly complex professional skills, and arduous flight tasks.

The world's first cosmonaut was Yuri Gagarin of the Soviet Union, who entered the Taino sedan in April 1961 aboard Vostok 1.
