Listening to a conversation in class about fake milk reminded me of what I once saw on a show while in Japan; fake eggs. The video is here (sorry, it's in Japanese with Chinese subtitles…):
It also talks about other things that can be made to look like food, like grapes and sausages.
The guy making the various fake foods says that he's not making fake food and is making "artificial food" but it's not his problem how people use it.
I didn't see this one while in Japan, but what I saw also had a clip where they showed the tutorial DVD that talks about how to make fake eggs, and the DVD was sold at an expensive price despite the fact that they didn't show how to make the shells.
I found an article here: http://www.hoax-slayer.com/fake-eggs-china.shtml
by searching for fake eggs and it seems like this was considered a hoax once for cover up. But then they comment that"the fake egg was made from calcium carbonate, starch, resin, gelatin and other chemical products," which was what the tutorial video captured on a show revealed as well. I'm not really sure what to think about the reality behind the fake eggs though if people can make them, we never know what human beings would think of doing with it…anyway, it's certainly unappetizing…
