i don't really want to post this question, but which application needs to pump meat through pipes?
will the different kinds of meat make such a difference?
"hey, chicken goes much more smooth in here..."
meat isn't really expensive, so if you need to perform tests, why not with different kinds of meat instead of a supplement, which will be more expensive, i'm sure.
as to where to find physical properties, i'd try with some meat packing plant, perhaps they will guide you to appropriate ressources
