Though pineapple is a sweet yet acidic fruit that many people enjoy, it can cause a burning or prickling sensation because of a type of enzyme known as bromelain, which makes some people dislike it. However, there are several ways you can lessen the effects of pineapple on your mouth.
Foremost, if you have a sensitive mouth, you should never consume the center of a pineapple or even its edges. Soaking pineapple in salt water, as well as cooking the pineapple, should lessen the effects of the enzyme.
Another strategy to mitigate the effects of the fruit is to combine it with dairy products. The enzymes should not irritate your mouth because they have more protein to feed on, and the dairy will help level out the pH of the pineapple.
