Bromelain Explained: The Enzyme Hiding in Pineapple

Pineapple tingles on your tongue. That tingle is a clue to one of the most interesting ingredients in BreathiZen.

What is an enzyme?

An enzyme is a protein that speeds up a job inside a living thing. Your own body makes many enzymes for digesting food. Plants and fruits make their own too.

Meet bromelain

Bromelain is a group of protein-digesting enzymes found in pineapple. The stem has the most. That is why fresh pineapple makes your mouth tingle: the enzyme is gently breaking down proteins on your tongue.

Bromelain in the kitchen

Cooks use fresh pineapple juice to tenderise meat, which is the enzyme at work. This is also why fresh pineapple ruins gelatin desserts, while canned pineapple does not, since heat stops the enzyme.

Bromelain in BreathiZen

The formula includes bromelain as its enzyme ingredient, next to mullein and cordyceps. It gives the formula a different kind of ingredient from the rest.

Try this at home

Cut a small piece of fresh pineapple and hold it on your tongue for a few seconds. That tingle is a natural, safe, everyday demonstration of what bromelain does.
