Sim-Meat also called synth-meat, cultured meat, cruelty-free meat, shmeat, and test-tube meat, is an animal-flesh product that has never been part of a living animal. Cultured meat is prohibitively expensive and differs from the vegatable-based Protein Concentrate.
The process of developing in vitro meat involves taking muscle cells and applying a protein that promotes tissue growth. Once this process has been started, it produces meat indefinitely without introducing new cells from a living organism.Two months of in vitro meat production can deliver up to 50,000 tons of meat from ten pork muscle cells.
Like protein concentrate, most people find sim-meat to taste exactly the same as "real" meat (chicken, beef, pork, etc) although some claim to be able to tell the difference. However, the real (price) difference comes from overall improvement of the product: texture, cooking/browning process, etc.
