Introduction of space food

The key to the production of space food lies in "space breeding," which is to use satellites to carry seeds to the heavens, and to use special conditions such as strong cosmic radiation, microgravity, and high vacuum in space to make seeds occur under atmospheric and gravitational conditions different from those on Earth. Gene mutations and chromosomal aberrations are then returned to the ground for cultivation. After research confirmed that "space foods" mostly have high yield, good quality and excellent performance. For example, the content of vitamins increased by 26% and the dry matter content increased by 19% in space tomatoes compared with ordinary tomatoes; while the number of space peppers numbered “87-2†averaged 300 grams each, and the maximum amount was 500 grams or more. The yield was relatively high. 20% to 30%. "Space foods" are generally slightly higher in price than ordinary foods.
   Seventeen kinds of space foods can be eaten with confidence. So far, there are 17 varieties of "space foods" in China that have passed the appraisal and approval of relevant state departments, can be cultivated and marketed on a large scale, and more than 50 strains are still in the experimental stage. . The 17 kinds of space crops that have been approved include rice, wheat, soybeans, cotton, lotus seeds, green peppers, tomatoes, ganoderma lucidum, and watermelons. More than 50 strains that are still in the experimental stage or cultivated in small scale include shiitake mushrooms, enoki mushroom, rapeseed, and sorghum. , mung bean, eggplant, gourd and so on. The former have already passed the appraisal and accreditation by the relevant state departments, and can be cultivated and listed on a large scale. These fine varieties from space will enter millions of households.
   Theoretically, absolutely safe space foods are theoretically absolutely safe foods. "Space foods" have not introduced foreign genes because of space breeding. They are caused by chromosome breaks and rearrangements of genomes caused by special conditions in space. No toxic substances will be produced in the United States. Tomato seedlings in the United States have been proved to be non-toxic by toxicity tests, and nutrient analysis of rice progeny mutations at Guangxi Agricultural University in China has not found any toxic substances. For many years, no one had caused adverse reactions due to the consumption of such foods, and a large number of facts have proven that the “space foods†approved by the national appraisal can be eaten with confidence.
Can food products like GM foods have security concerns? In this regard, China's agricultural experts have repeatedly stressed that the safety of space food is beyond doubt. Please rest assured that you enjoy it. Aerospace breeding allows seeds to induce seeds to mutate under conditions such as space microgravity, high vacuum, and cosmic ray radiation. This variation is the same as the natural variation of natural plants, except that time and frequency have changed. Experts believe that space breeding has produced genetic mutations in crop seeds, but this type of mutation is only one type of gene that produces a different allelic gene than the original, such as high-stalked dwarf, early-maturing and late-maturing. The resulting chromosomal mutations are essentially the same as the inheritance, isolation, and recombination produced by hybrid rice breeding, with no safety implications.
The radiation of cosmic rays in space is greatly enhanced. This is also an important condition for variation. Radiation breeding in the middle of the last century was a widely used method of breeding improved varieties. Over 50 countries had successively cultivated and used more than 1,000 new varieties of crops. Radiation doses used in radiation breeding were only dozens of international food safety radiation levels. In one part, the radiation dose of space breeding in space is less than one percent of radiation breeding.
Space breeding is different from genetically modified foods. Transgenic crops are new varieties that have been introduced into plants using foreign genes. For example, genetically modified soybeans use non-soybeans, even animals and microorganisms to introduce mutations, and space breeding is to make crops. The seeds themselves are mutated. The regulation on the safety of genetically modified products promulgated by China specifically excludes the management of new species that have been generated through mutations. It also shows that space foods are very safe and there is no scientific basis for their safety. Tomato seeds in the United States have been proved to be non-toxic through toxicity tests. Nutrient analysis of rice progenies in Guangxi Agricultural University in China did not find any toxic substances. The "space food" has been in production for more than a decade. During this period, no one has caused adverse reactions because of eating such food.
  "Space food" is not all "green"
Although space has a non-polluting character, not all "space foods" are "green foods." Whether or not "space food" is "green food" depends entirely on how it cultivates on the ground. Many "space foods" are also chemically fertilized as ordinary foods, so they cannot be called "green foods." In fact, the difference between "space foods" and ordinary foods is that it is through space mutation breeding, and when the ground is in the cultivation phase, they are treated equally and there is no particularity at all. Some "space foods" may also use chemical fertilizers during the cultivation process. How to correctly identify "green food" also depends on whether there are "green food" signs issued by the relevant state departments.
There are many misunderstandings about the understanding of "space food" in society. Strictly speaking, "space foods" are foods consumed by space astronauts. What do astronauts eat in space now? Almost exactly the same on the ground: black bread, honey cakes, ham, pork with sweet and sour sauce, clams, polish barracuda, Russian cheese, salmon, vegetable soup and red vegetable soup, strawberries, biscuits, chocolate, tea and coffee . Astronauts no longer need to suck from the hose. They are packaged in specially made containers and can be placed directly on a heating table or in polymer. Even the second dish does not need to be sucked. You can use a spoon or a fork to feed. What most people call "space foods" should be called "space-induced breeding products."
