I believe that photo is actually of mechanically separated chicken.
I understand that the process is similar to how they produce “pink slime”. The end result is a slurry.
I believe mechanically separated chicken may actually be sold as a stand alone product in the form of Chicken Nugget type foods. I could be wrong about that though.
The “pink slime”, aka “finely textured beef” is a beef filler which is added to ground beef. I think it is actually too lean, among other reasons, to be sold as a stand alone product.
It is claimed the nutrition is roughly the same as 90/10 beef. I haven’t tried it, but it sounds like it would be better than a burger from 93/7 (which are decent, if not as tasty as say 75/25).
If it was cheaper than 93/7, and available, I would definitely try it, however, it appears BPI built their business on USDA school contracts, and recently, pet foods. I think the BPI disaster is more a lesson of why you shouldn’t hitch your wagon to the government in any shape or form, unless it’s the defense industry and you have very good lawyers.
I would suspect that any left over ammonia cooks off if you go for well done (I do on my burgers, unless I make them from packaged ground beef).
