There are two different issues that you bring up: One is an issue of creating specific protein(s), and the other is creating "meat". "Meat" is really a culinary term, not a scientific one, and describes animal muscle, which is often cooked. There is no way that a plant is going to produce animal muscle and still be a "plant". As far as a plant producing specific proteins, that seems possible in theory, but extremely difficult in practice.
I think I understand your question a bit better now. You are not trying to create a product that tastes like meat or has the consistency of meat. You are trying to create a nutritionally balanced plant-based food that can simulate meat in the way it's processed metabolically by humans. This is a different goal. Adding the ability for the plant to produce B12 would be a start. Such an ideal "super plant" should contain all amino acids needed by people.
As for how to do this, I have no idea. What you're proposing is very complicated, and beyond my scope of understanding.
Hello, walkingfish. Thank you for your answer. Yes, I'm trying to create a nutritionally balanced plant-based food that can simulate meat in the way it's processed metabolically by humans.
It will look like that - you eat some soybeans or rice, and you get all B's (B6, B12), amino acids and proteins. It will be cheat meat, and we will not need to kill animals anymore.
I'm russian, and I don't know anything about biotech. Walkingfish, we should tell this idea to people. What do you think? As many people as we can. Maybe we should even send this idea to some biotech magazine (if there is any). Do you know any news group/magazine/forum/online meetings? Can you write some article and send this article to these people? I can't, but I want to help people and animals.
If you guys wish to write some article and spread it to maximum people, then I guess you already are on the right platform...this forum should be a nice means to communicate...
