Why do you want to soak pineapple in salt water?

There is a bromelain called bromelain, which can decompose protein. If it is not soaked in salt water, this enzyme will stimulate people's mouth. It is recommended that the cut pineapple be soaked in salt water before eating. Salt can inhibit the activity of pineapple enzyme, reduce the irritation of pineapple to mouth and lips, and increase the taste of pineapple. In addition to vitamin C and sugar, pineapple pulp also contains many organic acids, such as malic acid and citric acid, and also contains a kind of pineapple enzyme, which can decompose protein. If we don't soak in salt water first, this enzyme will stimulate the young epidermis of our oral mucosa and lips, making us tingle. Avoid allergic reactions. Pineapples are soaked in salt water on the one hand to avoid allergic reactions. Some people may have an allergic reaction after eating pineapple. After eating pineapple, it can suddenly attack from 15 minutes to 1 hour, with abdominal pain, diarrhea, vomiting or headache, dizziness, flushing on the skin, itching all over, numbness in limbs and mouth, and even a series of allergic symptoms such as dyspnea and shock. People used to call this pineapple allergy "pineapple poisoning" or "pineapple disease".
