A wonderfully ripe pineapple is usually a problem to search out and carve, however when you’re right down to these golden rings, you have obtained an ideal summer time companion. From piña coladas to pizza, the juicy hunks might be laborious to stop — till the within of your mouth begins to really feel weirdly uncooked.
If one too many bites of pineapple go away you with a tingly tongue, burning cheeks or a determined need to scratch the within of your mouth, you are not alone. The perpetrator is probably going an enzyme advanced known as bromelain, in response to a 2019 letter within the journal Annals of Allergy, Bronchial asthma and Immunology. Bromelain is a protease — a sort of enzyme that breaks down proteins into their constructing blocks, often called amino acids — that is distinctive to pineapples, which is why pineapples are additionally glorious meat tenderizers.
“In the intervening time, there is not loads of proof in regards to the palatability of bromelain,” or the way in which the enzyme tastes and feels in your mouth, stated Alessandro Colletti, a pharmacologist who research bromelain on the College of Turin in Italy. However it’s potential that after consuming a number of items of pineapple, you may start to really feel the bromelain breaking down a few of the mucin proteins that make up the protecting mucosal layer in your mouth.

So, when you dive right into a fruit salad, is it potential that consuming an excessive amount of pineapple will do you hurt? It is uncertain, Colletti stated. He famous that bromelain is not harmful to people (although it’s an efficient protection in opposition to pests that will harm the pineapple plant). “If you eat pineapple, the focus of bromelain is about 500 micrograms per milliliter,” he stated. “So the focus will not be actually excessive.” It is even secure at a lot larger concentrations. As an example, bromelain oral gel, which has a focus 200 to 400 instances larger than recent pineapple, might be utilized on to the mouth as a result of its anti-inflammatory properties can offset mouth sores brought on by chemotherapy, Colletti stated.
Furthermore, your mouth rapidly begins to exchange any of the cells broken by bromelain to forestall any everlasting harm or change by the pineapple’s proteases, in response to experiences by Bon Appétit.
Different tropical fruits, similar to papaya, have comparable proteases however do not go away a uncooked feeling within the mouth. The acidic nature of pineapple could also be partly responsible for its bizarre impact, Paul Takhistov, an affiliate professor of meals engineering at Rutgers, the State College of New Jersey, informed Self. Pineapples sometimes fall between 3 and 4 on the pH scale (a rating of seven is impartial), in response to Healthline. Takhistov hypothesized that bromelain dissolves a few of the mucin proteins within the mouth, which makes your mouth extra delicate to irritation by the pineapple’s acidity. It is really the 2 collectively, the acidity and the enzyme, that doubtless make your mouth sore, he stated. Colletti added that bromelain itself can have an acidic taste, which could add to the acidic expertise.
As for easy methods to bypass the tingling, in a single episode of Netflix’s Ugly Scrumptious, a person in Mexico tells Danish chef René Redzepi to soak the peeled pineapple in saltwater. Nonetheless, there is not a lot scientific proof to again this up. It’s also possible to grill the pineapple or heat-treat it in another means, as warmth deactivates enzymes, Bon Appétit reported.
And if you wish to get the advantages of bromelain, similar to its antioxidant properties, Colletti stated taking a complement is finest. That means you get larger concentrations of bromelain with out all of the sugar that makes pineapple so candy.
