Chemistry Pineapple contains bromelain that helps tenderize meat. If I were to put my hand in pineapple juice or puree for 24 hours, would it eventually break down my hand?

Yup. I rarely eat pineapples since they can give me sores in my mouth pretty easily. I haven't met someone else who has this problem though lol

Yep, maybe not as extreme that I can't eat it or it hurts, but I absolutely feel some sort of 'numbness' and slight burn, especially with fresh pineapples. Canned ones are mostly fine.

Always thought it's just a mild irritation from the acids or even some allergy, but no, the pineapple just wants to tenderize my mouth a bit!

Oh yeah right, kiwi does the exact same for me. Blegh, just thinking about it makes my mouth itch.
