The author above most likely means soy granulate. However, this can hardly be called artificial meat.
This term better refers to meat that is grown in the laboratory by breeding cell cultures. A small part of the animal's muscle tissue is selected, after which it is "built up" on nutrient media. After enough time, you get a small piece of meat.
this meat is made from soy flour and water, that's all.
it's just that soy contains a lot of protein, and therefore this meat can be replaced with natural meat, during fasting or if you are a vegetarian
