Hydrolyzed Proteins?!
If that is true, how do they make things like hydrolyzed soy/wheat/whey/ect. protein..?
Answers: Are hydrolyzed protiens vegan? I heard that they're animal bone-and-hoof derived, defintly -not- vegan friendly, but I can't find any evidence anywhere else to back that up.

Any hydrolyzed protein is just another term for MSG, which a lot of people are sensitive to. But usually it will say "hydrolyzed vegetable protein" or "yeast extract" or something along those lines.
Unfortunately there is no way for you to know if they are 100% vegan friendly because a hydrolyzed protein is a protein that's been broken down into it's component amino acids, and they do this either by boiling it in an acid or base, or by using the pancreatic protease enzyme to break it down. Boiling in acid = vegan friendly, pancreatic enzyme is not. And they do not put that on food labels so there's no way to tell which was used.
My understanding is that it can come from any protein source. If it explicitly states that it is vegetable/wheat/soy then it's vegetarian, but if it only says hydrolyzed protein I would stay away. Just like "natural flavors"...you never know.
They can come from vegetables. What you are asking is about a product of a process, not a source.
