Shenzhou XII astronauts "business trip" home today, what do they want to eat most? "The Book of Han and the Tale of Li Shiqi": "The king regards the people as heaven, and the people take food as heaven." Astronauts have enough to eat in the sky to have spirits! On June 17, astronauts Nie Haisheng, Liu Boming and Tang Hongbo became the first batch of astronauts stationed on the Chinese space station, starting a three-month space "business trip" life. Today, having returned to the embrace of the motherland, do you want to know what they want to eat most after they "go home"?
First, the production of astronauts' space recipes
In order to ensure physical health, astronauts should eat special food in space, and the production of space food must meet the conditions and medical requirements of manned space engineering, following the following principles:
safe. First, quality and safety. Space food must meet the requirements of hygiene, can not make astronauts have any foodborne diseases and food poisoning, can be long-term quality preservation. The second is food safety. In the weightless environment of space, food can not have debris and debris, debris and debris will float into important instruments, causing irreversible damage to equipment, or into the astronaut's respiratory tract, resulting in suffocation. Gas can not be produced, people in weightless environment hiccups are very difficult, gas suspended in the stomach, astronauts will feel uncomfortable.
nourishment. Space food requires rich and balanced nutrition, to ensure the health of astronauts and daily energy reserves, such as protein, fat and glycoside needed by the human body every day, containing calcium, phosphorus, magnesium, potassium and other major inorganic elements, containing iron, zinc, selenium, iodine and other trace elements, as well as two fat-soluble vitamins (vitaminS and E) and a variety of water-soluble vitamins (vitamin B and C, etc.).
convenient. Eating in the weightless environment of space, food will float around in the spacecraft cabin, generally to process food into a bite size, food packaging generally can not have a flowing soup, that is, the so-called "bite to eat" food, convenient for astronauts to eat.
abundant. In the long-term flight of space, astronauts are in a state of weightlessness and small space, and appetite is easy to decline, so space food must also be rich in variety to stimulate astronauts' appetite. In order to avoid monotony, the recipe is generally based on a cycle of 4 to 6 days, and the food is not repeated every day except for drinks in a cycle. In addition, pay attention to changes in food during different flights as needed, and it is necessary to limit or increase certain foods.
personality. Astronauts have their own tastes, and they need to develop personalized recipes based on healthy nutrition requirements so that astronauts can eat their favorite foods. Second, the changes in the food of Chinese astronauts
After more than half a century of development, the world's space food has undergone many updates. From the era of "toothpaste", the era of "instant noodles", the era of "canning", the era of "cooking", the era of "snacks", the era of "takeaway", and now the era of "kitchen", aerospace food has undergone an evolutionary process from difficult to swallow to hearty, from solving food and clothing to nutritional balance. China's aerospace food is developing by leaps and bounds:
More variety. With the increase in the number of missions and the growth of time, the variety of space food is becoming richer and richer every time. Shen V "1 person 1 day" flight, 20 or 30 varieties. Shen Liu increased to 40 to 50 kinds, including soft and hard canned food, compound water food, compound water vegetables, freeze-dried fruits, condiments, pastries, staple foods and drinks, each with a variety of choices. In terms of staple food alone, there are four varieties of white rice, eight treasure rice, curry rice, and sticky rice, which can be eaten every day, and there are freeze-dried chocolate cream ice cream after meals, and there are three kinds of special spicy, sour and sweet sauces. On the Seventh God, the variety of food for astronauts has increased significantly from more than 40 to nearly 80. Shen Jiu, the "kitchen" can store at least 80 kinds of food, four days will not eat heavy food, astronauts can eat fried rice three meals a day. There are 88 kinds of space food in Shenshi, more than 100 kinds of food in six categories of Shenshi, and recipes in a cycle of 5 days. Shen XII is equipped with more than 120 kinds of aerospace foods with balanced nutrition, rich variety, good taste and long shelf life.
More balanced nutrition. Because of the continuous enrichment of food varieties, astronauts get more balanced nutrition. Yang Liwei, an astronaut of shenwu, only ate snacks and coffee during his more than 20 hours in space. Shen Eleven is equipped with 100 kinds of aerospace food, divided into six categories: main food, side food, instant food, drinks, condiments and functional foods, the recipe cycle reaches 5 days, and the diet structure is more scientific. Due to the significantly longer flight time of the Shen Xi mission, in order to alleviate the impact of the weightless environment on the human body, foods rich in vitamin D and unsaturated fatty acids, promoting Na excretion, and high in coarse grains and dietary fiber have also been added. Shen XII is equipped with more than 120 kinds of aerospace food, not only divided into main and secondary foods, but also pay attention to meat and vegetarian collocation, astronauts can not only eat dishes of different factions, drink a variety of tea, juice, soup, yogurt, but also eat fresh fruits.
Personality is more pronounced. Shenqi astronauts can also add sour, spicy, salty and other flavors of condiments according to their own preferences, and the Shenjiu food bag is equipped with char siu sauce, Sichuan-style chili sauce and so on. Shenshi is personalized according to the taste of the astronauts, and on the basis of Shenjiu, bean paste dumplings, fresh fruits, millet porridge, yogurt and so on are added. Shen Shi's sauce is one more than Shen Jiu, which is customized according to the tastes of Nie Haisheng, Zhang Xiaoguang, and Wang Yaping, and improves the sensory acceptance of food through improved processes.
The equipment is more advanced. The food of Shen No. 5 is ready to eat, and it does not need to be heated, added water, or tableware when eating. The astronauts of Shen Vi can eat hot meals. Shenqi food heating will use the main power supply of the cabin, rice and vegetables can be packaged in a heater for heating, there will be no more "sandwich rice", astronauts can eat the real sense of stir-fry for the first time in space. God XII opened up a dining area, equipped with food heating, refrigeration and drinking water equipment.
Third, God XII wants to eat the first meal when he returns home
The three astronauts of God XII "traveled" home today. After returning to the embrace of the motherland, what do they most want to eat?
