Why do papayas have papain?

Question

I know that we use papain as a meat tenderizer, but what do papayas use it for

Answer 1

Other fruits have it also, such as pineapple. You can not put raw pineapple into jello because it will digest it.

Other fruits have different strange contents. Apples have pectin that makes jelly gel.

Why do peppers have capsacin?

Why is wintergreen oil good for our stomachs?

Answer 2

It's a digestive enzyme. That is to say it breaks food down. Specifically papaya, but it works just as well on other things.

This is the crux of the "raw food movement." Raw food contains it's own enzymes to properly break it down. Making it more digestible than cooked foods. Cooking destroys the enzymes.

People love "aged" meat because it's tender. All "aged"  means is "digested." The meat is digested, or decayed, by it's own enzymes.

For instance, when we die, cathepsin, our own self-digesting enzyme, will eat away at our bodies until we are nothing but bone.
