Papian?

[classicrockgriller]

Not so much papaya, but papain.

Is a difference

[DTAggie]

And here I had always hear it was an aphrodisiac

[DarqMan]

I wonder what a little Adolphs sprinkled on a brisket an hour before throwing on would do?

[classicrockgriller]

It's good for Arthritis. ;D

Fresh (not canned) pineapple with do the trick too.  It contains a proteolytic enzyme called bromelain (pineapples are in the Bromeliaceae family).  Canning or heating pineapple denatures the protein.

SS;

If you are using pineapple juice for flavor, and not as a tenderizer, heat the pineapple juice to 185°F and keep it at that temperature for a couple of minutes. That will destroy the enzymes that break down muscle tissue, and you can marinade as long as you wish.

Dang now that is interesting.  Could you do that to a wild hog you shoot?

If you can find a way to hold the wild hog still long enough to inject it with papian right before you harvest it, you're a much better hunter than me  ;D
