Why do pineapples soak in brine

First, because there is an enzyme in pineapple, if eaten directly, it may cause allergic reactions, diarrhea, vomiting, headache and other symptoms, and may also stimulate the oral mucosa and the tender skin of lips. Salt water can destroy this enzyme, if the soaking time is not enough, pineapple enzyme does not completely lose its activity, may still cause allergy.

Second: if the soaking time is too long, it will not only cause excessive loss of pineapple nutrition, but also because pineapple is rich in sugar, it is easy to breed bacteria when it has been soaked in water.

Third: it's best to soak pineapple for about half an hour, which can avoid all the above problems and make pineapple more sweet.

Soaking in salt will also neutralize its acidity, reducing the possible harm to the body.
