Why Does Pineapple Sting Your Tongue? [ID0923]

Ever wondered why pineapple feels like it’s biting you back? 🍍
That strange stinging or tingling sensation isn’t your imagination—and it’s not an allergy either. In this video, we break down the real science behind why fresh pineapple can make your tongue feel sore, raw, or slightly burned. From protein-digesting enzymes to acidity and texture, you’ll discover how this fruit literally starts digesting you the moment you take a bite.

We’ll also explore why cooked or canned pineapple doesn’t sting at all, how pineapple can prevent gelatin from setting, and why this same effect is used to tenderize meat. It’s a simple everyday food with some surprisingly aggressive chemistry hiding inside.

If you enjoy learning the hidden science behind ordinary foods, this one’s for you.
