According to foreign media reports, scientists said that the first batch of "test tube" hamburgers will remain in reality for a year. They believe that this product (using beef derived from stem cells) will meet people's carnivorous needs without killing animals.
According to Dutch scientists, the global population will increase rapidly in the next few decades. At that time, there will not be enough domestic animals to satisfy everyone's demand for meat. Therefore, they stated that it would be commonplace for beef, chicken and lamb to “grow†in future food laboratories. Scientists are currently developing a hamburger that is grown from 10,000 stem cells obtained from cattle. The number of these stem cells that divide and form muscle tissue that resembles beef increases by more than a billion times. This product is called "test tube" meat.
Mark Post, PhD, professor of physiology at the University of Maastricht in the Netherlands, took part in the experiment. He said: “I think we will not be able to rely on traditional animal husbandry to provide adequate meat for people in the next few decades. Being our only choice. We are trying hard to prove to the world that we can produce such products. We need to find the first person who is willing to try this kind of meat. If nobody wants to try, I will become this person." Scientific American magazine said he believes that they can produce the first such hamburger within 12 months.
In 2009, scientists from the same university used the same method to grow several slices of pork. They admit that this meat is not particularly good and it tastes like the taste of a calamari. Scientists also used muscle tissue obtained from goldfish to grow fish slices in a laboratory in New York. Although the initial results were different from those produced by animals, scientists believe that the public will soon get used to it, especially when they have no choice. One of Post's colleagues said: "When we were eating hamburgers, we wouldn't think we were eating a dead cow." When people can't get the meat from livestock, it's easier to let them accept artificially cultivated meat.
With the increasing population, global meat consumption will double in 2050. The Netherlands is the world's largest producer of artificial meat, and the government has invested 1.5 million pounds (2.4.08 million US dollars) for this research. Scientists involved in the study believe that the test tube hamburger is currently only in the initial stages of food reform, but in the end it will solve the problem of inadequate meat supply. Researchers from the Utrecht University in the Netherlands concluded that the first 10 stem cells would produce 50,000 tons of meat within two months. A study at the University of Oxford in the United Kingdom found that this method will reduce energy consumption by 35% to 60%, save 98% of land, and generate 80% to 95% of greenhouse gases less than traditional livestock husbandry.
How to use stem cells to produce hamburgers
Here is the process of producing hamburgers using stem cells:
1. Obtain cell samples from healthy cows;
2. 10,000 stem cells obtained;
3. In the lab's vessels, cells are divided into billions;
4. The new muscle cells growing on the vessel are stretched by the tension;
5. The muscle fiber is chopped to make a hamburger. (xiaowen)
