bromelain will hydrolyze protein, and the tongue is mainly protein, which is equivalent to hydrolyzing your tongue. In addition, the alkaloids contained will also play a role. It is better to soak in salt water before eating. Salt water can absorb alkaloids and inactivate protease at the same time, so that the tongue will not be numb. It is the same reason that my family will dip in soy sauce before eating pineapple. But if you are really numb, you may be allergic. It's just possible. Maybe you should see a doctor.

Drinking some salt water will relieve you, because some ingredients in pineapple will make your tongue feel broken and painful, but salt can alleviate this problem, that is, you should soak pineapple in salt water first.

please adopt it, thank you! !
