Shenzhou ten after fifteen days of space travel, three astronauts successfully returned to earth. This is the closing battle of the first stage of the second stage of the "three-step" strategy of manned space flight in China, and also the first applied flight of the manned space project in China. It not only verifies the manned spaceflight related technology that our country has mastered once again, but also makes people have new expectations and expectations for space applications.

As part of the exploration space program, the development and development of space food also developed along with the manned space industry in China, laying the foundation for the future space station construction. The ten voyage, not only enriched the variety of food, but also made personalized recipes for the taste of the astronauts in China, and adjusted the food packaging technology according to the scientific data. The more important thing was to optimize the operation procedure to ensure the health and safety of the food, so that the astronauts had passed the God ten of the whole food. Tour.

"Chinese taste" of the fragrant space

The ten astronaut's recipe is more abundant than ever, and the variety of food has been expanded to more than 88 kinds. In addition to a wide variety of fish, canned meat, bread and so on, it also continues the "Chinese taste" of the Chinese space food, such as fish silk, kung pao chicken and so on, which includes the soy sauce provided by the Chinese hundred year brand Lee Kam Ji. . It is understood that most of the God ten space food is added or improved on the basis of God nine food, and the taste is more in line with the eating habits and tastes of the astronauts. Not only that, because of the different space environment in different stages of the ten task of God, the difference of the physiological index of the astronauts at different stages and the different tasks to be carried out, the space meal menu of God ten is also divided into 4 kinds, whether on the category or in the collocation, the space diet of each task period is different.

In the space, the staple food such as dehydrated rice and curry rice is packed in a silver gray bag of book size. Because of the habit of drinking tea in China, Chinese astronauts also love to drink tea, so in addition to regular drinks, fashionable modern beverages, such as iced black tea and green tea, are also complete. Researchers also prepared strawberries, apples, bananas, peaches and other fruits for the astronauts. In order to save, the water was removed at low temperatures and processed into freeze-dried fruit. In addition, the astronauts' food packages also include chocolate, ice cream and zongzi specially developed and packaged snacks.

In order to prevent astronauts from appetite, Shenshi food also uses individual selective diet to enhance the appetite of astronauts and increase food intake. According to aerospace food expert Bai Shumin, personal selective diet is to choose the food that the astronauts choose to choose their favorite food before flying, and the food nutrition experts make the diet after meals for them to eat custom food in flight. In addition, the astronauts in the ground training, also specially aimed at the space food for two times each 4, 5 days of trial, and put forward comments after the trial, space food and nutrition experts to research and improvement, finally brought into space. As the astronauts eat the same kind of food in space, the different flavors of soy sauce are more frequently used to regulate the difference in astronauts' taste. To this end, the food provider of the God ten space mission Li jimji also upgraded the sauces from "five tiger sauce" from God nine to Sichuan flavor spicy sauce, garlic chilli sauce, spicy sauce, tomato sauce, Thai sweet sauce and bean paste sauce.

The potential risk of eliminating the corners of the mouth

Eating with your mouth open is almost an innate instinct for people living on the ground, while astronauts in space practice over and over again. Because if space food is scattered or flying around, it will be very dangerous: once the food residue enters the astronaut's respiratory, otolaryngology and eyes and other organs, it is likely to cause fatal damage in the microgravity environment.

Based on this consideration, God ten has also made technical updates and adjustments. For example, in the food packaging, the soy sauce supplier Lee Kam Ji has improved it on the basis of previous packaging to make it more suitable for the space environment. Less food risk, but also reduce the production of packaging waste to save storage space, more safe and environmentally friendly and convenient.

Space food is expected to be "cloud sauces"

The aerospace industry is constantly developing, and in the face of the farther space dream, the aerospace food will continue to improve and achieve breakthroughs. From Shenwu to Shensi ten, China's space food has also undergone tremendous changes. And how will China's space food develop in the future? These problems have been widely guessed, and perhaps Chinese astronauts can cook food in the sky in the near future, cook all their favorite foods and enjoy the fun of space.  Or maybe Chinese astronauts will become "space farmers" in the future, growing fruits and vegetables in space, and realizing the self-sufficiency of space food. At the same time, the feeling of being able to eat with the common ground on the ground is infinite.

In order to meet the needs of the future Chinese people to carry out the manned lunar landing project and even the interstellar travel, meet the high standard of space food, as a partner of China's space space, the space food will be further upgraded and technological innovation. In order to meet the physiological changes of astronauts under weightlessness conditions, and considering the future will be longer.
