Different tropical fruits, equivalent to papaya, have related proteases however do not go away a uncooked feeling within the mouth. The acidic nature of pineapple could also be partly guilty for its bizarre impact, Paul Takhistov, an affiliate professor of meals engineering at Rutgers, the State College of New Jersey, advised Self.

Nonetheless, there is not a lot scientific proof to again this up. You may as well 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, equivalent to its antioxidant properties, Colletti stated taking a complement is greatest. That means you get increased concentrations of bromelain with out all of the sugar that makes pineapple so candy.
