Angesichts des rasanten Fortschritts in der Biotechnologie entsteht eine innovative Alternative zur herkömmlichen Tierhaltung: Fleisch, das durch die Züchtung von Zellen unter sterilen Laborbedingungen produziert wird. Dieser Artikel erläutert die Herstellungsmethoden solcher Lebensmittel, untersucht Fragen der mikrobiologischen Sicherheit, des Nährwerts sowie der gesellschaftlichen Akzeptanz und vergleicht zudem dessen ökologische Auswirkungen mit denen der konventionellen Fleischproduktion. Kann diese Technologie eine tatsächliche Lösung für die globalen Ernährungsherausforderungen darstellen?
How do you make meat in a lab?
First you take the stem cells from the living organism, which have the unique ability to become any cell in the body. Then you multiply them until the muscle tissue is formed. The multiplication process takes about two months, and then they are divided into different types. This sort of separation allows you to get a different structure of the meat. After the development process is complete, you add the fat grown in another breed and the colorants, and when the meat is deprived of the blood, it will be its main colorant. Now it's enough to get to the flavor and flavor.
The meat from the sample has its advantages
The main advantages of such meat production are a significant reduction in the energy and raw materials needed to produce 1 kg of raw material, and therefore less consumption of natural raw materials, less space needed for pasture and fields for grazing crops. Additionally, the production of methane to the ecosystem will decrease. However, for many, the most important factor may be ending animal suffering because even stem cell harvesting takes place under anesthesia. In vitro meat may be healthier than natural because scientists carefully plan its yields. For example, adding fish cells to beef will make it contain omega-3 fatty acids that are beneficial to organisms.
The meat from the sample is defective
It's a relatively new method of obtaining food, the first batch of meat obtained in the laboratory was created in 2013, and the head of the research team was Mark Post of Maastricht University in the Netherlands. There are still many problems that scientists are struggling with. First of all, it's an expensive product at the moment, but over time its price will decrease, and increasing consumer interest will greatly help in this. Additionally, the meat obtained differs from our requirements for muscle tissue, which we can also process, so the taste needs to be improved.
Is this meat from the test tube an alternative to regular meat breeding?
It is clear from the results of the experiments to industrial production that there is still a long and bumpy road ahead. Scientists face many challenges, including choosing the right stem cells and the basis for their growth, as well as technological problems such as designing the right bioreactor to produce such a crop. As you can see, this technology is still in its infancy, but it has advantages that, if used efficiently, can solve some of the 21st century world's problems related to natural population growth and increased meat consumption.
