Original title: Harvard creates artificial rabbit meat in a method similar to 'roll marshmallow'? Netizen: will you get fat if you eat too much
Harvard made artificial rabbit and beef. Recently, a team of bioengineers at Harvard University took an important step in bringing artificial meat from the laboratory to the table. According to a new study, researchers have successfully cultivated beef, mutton and rabbit meat from an edible gelatin matrix for the first time, creating a substance that successfully imitates natural meat quality.
Artificial meat is a hot topic in recent years. There are two different types.
One is vegetable meat like impossible foods and beyond meat, which restores the texture and taste of animal meat with pea protein and soybean. This artificial meat has been available and is mainly used in hamburger patties.
The other is the experimental laboratory artificial meat, the subject of the Harvard study. The principle is to extract muscle tissue from animals and then put it into a bioreactor for cultivation.
For years, engineers have been studying bioengineering meat, extracting stem cells from animals and reproducing until they divide and form new muscle tissue.
However, when trying to grow environment-friendly meat in the past, it was found that it was difficult to reconstruct the long and filamentous muscle fibers that make up meat.
In their research, the Harvard team used the most popular food at the carnival to spin edible gelatin fiber with a rotary spinner, which is similar to the production process of marshmallow.
These fibers are similar to the 'extracellular matrix' of natural tissues, that is, the 'glue' that binds to tissues.
The cells of rabbits and cows are fixed on gel substrates and grow as long and thin as real meat.
The study said that compared with natural rabbit muscle tissue, the protein of this bioengineering meat looks very similar, although its tissue distribution is closer to processed meat such as ground beef rather than unprocessed meat.
According to the analysis of prospective industry research institute, driven by the needs of environmental protection, economy and health, the market scale of meat substitutes will grow steadily in the next few years. According to market and markets data, the global artificial meat market in 2018 totaled about US $4.36 billion; It is estimated that the scale of global meat substitutes will exceed 5 billion US dollars by 2020, 6 billion US dollars by 2022, and 6.43 billion US dollars by 2023; Among them, the market scale of meat substitutes in the Asia Pacific region has the fastest growth rate, and the average annual compound growth rate is expected to reach more than 8%.
