Does your tongue itch when you eat pineapple?

The main responsible for this sensation is bromelain, a proteolytic enzyme present in pineapple. Its natural function is to break down proteins, which makes it useful as a meat tenderizer. But when consuming fresh pineapple, this enzyme also acts on the proteins of the oral mucosa, causing that stinging or burning sensation.

In addition to bromelain, pineapple contains natural acids, such as citric and ascorbic, which can further irritate sensitive areas of the mouth. This is compounded by raffides, microscopic crystals of calcium oxalate that, although invisible to the human eye, can cause micro-abrasions on the tongue and cheeks, intensifying the discomfort.

Although the stinging sensation is usually mild and temporary, there are simple ways to reduce it. The most effective, and also the most intuitive, is to apply heat to the fruit. Cooking pineapple, whether baked, grilled or even flambéed, deactivates the enzyme responsible for the burning. Heat breaks down the structure of bromelain and, with it, its ability to irritate mucous membranes disappears.

Another strategy, popular in some households, is to soak the fruit pieces in salted water for a few minutes before eating. The salt can help to partially neutralize the enzymatic activity without drastically altering the taste. It is a simple gesture that softens the effect without detracting from the character of the fruit.

Finally, some people choose to combine pineapple with dairy products. Yogurt, whipped cream or even a little condensed milk not only add a creamier texture, but also act as a natural "buffer". The proteins present in dairy bind with bromelain, reducing its ability to act on the tongue and palate. The result is a smoother experience, without sacrificing flavor contrast.

It is important to distinguish between this irritation and a true pineapple allergy. While the former is common and temporary, an allergy can manifest itself with more serious symptoms, such as swelling, hives or difficulty breathing. In case of doubt, it is advisable to consult a specialist.

The next time you enjoy a serving of pineapple, remember that the slight itch is simply a natural interaction between the fruit's enzymes and your mouth. With a few simple precautions, you can continue to enjoy this delicious tropical fruit without any inconvenience.
