Eating and biting into pineapples can cause a tingling sensation and a sting in your mouth. This is faced by many pineapple lovers. Tap to know the reason behind this!

Bromelain's Role

Pineapple contains bromelain, which is a protein-digesting enzyme. These enzymes break down proteins in your mouth, causing a burning sensation.

Impact on Oral Tissue

Bromelain also dissolves the protein coating or mucus protects your tongue and mouth. This can cause a tingling sensation.

Acidic reactions

Pineapples contain pesky needle-type structures called raphides. Pineapple is also acidic, which can disturb the pH of the mouth.

How to prevent the pineapple tingling sensation?

Peel and cut the pineapple into smaller pieces. Soak these pineapple slices in a mild saltwater solution for 10 minutes to reduce bromelain.
