What are some foods that are forbidden to eat in space?

Human beings have never stopped exploring the universe, and space is part of human exploration of the universe. The curiosity about space has led to waves of astronauts pouring into space to explore its mysteries. The life of astronauts in space has also attracted a lot of attention at one time, including the diet of astronauts in space.

You must know that the environment in space is not very different from the environment on Earth, and the diet of astronauts will definitely be restricted in a vacuum, so what are the foods that are forbidden to be eaten in space?

First of all, bread, you know, the main ingredient of bread is fluffy flour, and bread that has been baked is usually very soft and fluffy. We often eat bread without paying attention, and our hands are already covered with crumbs. As mentioned earlier, space is a vacuum environment, and in a vacuum environment, if you bring bread to space, it is conceivable that the bread crumbs are very likely to float around uncontrollably, and if you are not careful, the crumbs may fly into the astronaut's eyes or respiratory tract, which is very dangerous for astronauts.

Therefore, for the safety of astronauts, bread is forbidden to be eaten in space.

The second is the carbonated drinks such as Coke and Sprite that we all are familiar with. That's because in the gravity-free environment of space, foods like carbonated drinks can become unappealing. You must know that one of the main pleasures of drinking carbonated drinks is the feeling of expansion and lightness of the gas contained in carbonated drinks after our body drinks them, but in space, the bubbles of carbonated drinks will become free floating due to environmental influences, and will not produce bubbles, so naturally it cannot be called a real carbonated drink.

Finally, there are the various types of alcohol that astronauts are forbidden to drink in space. The reason is that astronauts spend most of their time in space, and alcohol, as a flammable product, is very unsafe in a confined environment such as a space capsule. In addition, to a certain extent, astronauts go to work in space, and there are naturally many safety risks associated with drinking alcohol at work.

Therefore, for astronauts, alcohol is naturally contraband.

1.Bread, bread or any fragile biscuits are forbidden to be eaten in the sky, as these crumbs can get into instruments, cracks or astronauts' eyes and are dangerous; 2.Salt, first of all, is not allowed to go to space, and secondly, it cannot be put on food, because it is zero gravity; 3.

Ice cream, all the food that needs to be kept in the fridge, as the spaceship does not have a fridge.

Bread and flour grains, bread crumbs and flour grains can float in the surrounding environment and be difficult to clean, eventually causing unnecessary trouble.

Bread counts as one, because bread has a lot of crumbs, and if the crumbs float into the space equipment, the consequences are unimaginable.

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.

Summary. However, astronauts can't eat as much as they want. They must follow the recipes prepared for them by the ground nutritionist.

Astronauts on the U.S. Space Shuttle take out plastic bags labeled "Days First" from the pantry when they eat. Each plastic bag contains 7 food items for one astronaut to eat. Space food is dehydrated, and the food can be put into a bowl-shaped container before eating, and then a certain amount of water can be filled into the container with a syringe, and then put it in the oven to heat.

A meal can be "cooked" in no more than half an hour.

Hello, happy to answer your <>

There's nothing wrong with space food that doesn't need to be heated.

Astronauts can eat sausage pies, spicy grilled fish, roast beef with potatoes, creamy bread, tempeh broth, tuna salad, biscuits, chocolate, yogurt, preserved fruits, juice and other delicacies in space. The astronauts' food is rich and colorful, from the initial dozen to more than 100. Astronauts generally eat 4 meals a day, and the recipes are not repeated during the week.

However, astronauts can't eat as much as they want. They must follow the recipe prepared by the ground nutritionist. When the astronauts on the U.S. Space Shuttle eat, they first take out the plastic bag labeled with the first few meals of the day out of the pantry.

Each plastic bag contains 7 food items for one astronaut to eat. Space food is dehydrated food, before eating, the food can be put into a bowl-shaped container, and then a certain amount of water is poured into the dry stool container with a syringe, and then put into the oven to heat. A meal can be "cooked" in no more than half an hour.

The biggest concern people have about space food is its safety, but this worry is unnecessary. Scientists explained: there are no problems with the safety of food in space.

Because aerospace breeding is not to mutate plants through artificial methods, but only to accelerate the natural mutation process of plants that takes decades or even hundreds of years through some scientific means. Moreover, the International Atomic Energy Agency, the International Health Organization, and the International Food and Agriculture Organization have jointly determined that the safety of crop seeds cultivated by artificial mutagenesis techniques such as physics and chemistry is beyond doubt, and it is safe to burn seeds that fully meet the requirements of the specified indicators.

Everything in space has lost its weight and has become able to fly everywhere, like air. In this way, astronauts cannot eat at any time and chew as easily as they do on Earth, otherwise they will get stuck in the middle of the esophagus because the food cannot be swallowed, which is life-threatening. Therefore, scientists are developing spacecraft at the same time as researching the creation of space food.

After many times of space practice, scientists have found that space food requires nutritious, hygienic and easy to eat.

There are many kinds of food for astronauts to eat, including fresh bread, fruits, and chocolate, stir-fried vegetables, meatballs, etc., and condiments such as ketchup, which are packed in space food boxes. Most of these foods are highly concentrated, liquid. Therefore, when astronauts eat, they only need to "float" into the kitchen, fill a certain amount of water into the food box, heat it, and then squeeze the food into their mouths like toothpaste.

Of course, if you want to eat hard granular food such as peanuts, you can't send it directly to your mouth, otherwise it will be stuffed into your nostrils. A safer way is to let the peanuts float in the air and then open your mouth wide to catch them.

Because space food has the characteristics of low intake, high caloric value, and extremely rich nutrition, Japan first developed this commonly used space food for use on the earth. There are two commonly used space foods newly developed. One is liquid, called "nutritional rehydration", which is specially used for hospital patients, and a thin tube of a certain diameter is used to pass through the stomach when eating, and it is directly fed, which is better than the effect of intravenous drip.

The other is a solid "highly concentrated nutrient capsule". This space food, which is shaped like a capsule, can be made according to the needs of different people. This space food is now mainly used by the sick, young children who are picky eaters, infirm people with irregular diets, and undernourished athletes, and will become the most convenient and nutritious food for mankind in the future.

What is space food like? The food in the United States, Japan and China is very different, and I feel sorry for the astronauts after watching it.
