Experimenting with Real Enzymes: Bromelain

Adobe Spark

This post is part of our Summer of Science series! Check back periodically to find more fun, easy, and affordable experiments and projects you can do at home with your kids this summer. This project is about the enzyme, bromelain, which degrades other proteins. You will use it to turn chicken to mush while learning about experimental set up, controls, and the wonderful world of enzymes.

Oh, the first time I learned about bromelain was in college on a trip to Hawaii (I got a chance to observe Mars on the NASA IRTF on Mauna Kea). My friends and I flew there a week earlier than our telescope time to explore the islands a bit. One day, we each bought a fresh pineapple and each ate. the. whole. thing. Never do this, it was awful. I mean it tasted absolutely delicious, but our tongues and mouths were sloughing skin off for a few days as they recovered from being eaten themselves by the enzyme, bromelain.

Pineapple fruit has a very high concentration of fruit bromelain, a protein that can break down other proteins, aka a “proteolytic enzyme”.
