Why pineapple should be soaked in salt water
Make the flavor sweeter
Pineapple is best soaked for about half an hour, not only to avoid allergic accidents, but also to make part of the organic acid of pineapple decomposition in the brine, so that the taste of pineapple seems sweeter. In addition, pineapple also contains oxalic acid, which affects the body's absorption of calcium and iron, and soaking it in salt will also neutralize its acidity, reducing the possible harm to the body.
Avoid allergic reactions
Some people eat pineapple, allergic reactions may occur, in the consumption of pineapple about 15 minutes to 1 hour after the onset of the sudden, abdominal pain, diarrhea, vomiting, or headache, dizziness, flushing of the skin, the whole body itchy, numbness of the limbs and tongue, and even a series of allergic symptoms of respiratory distress, shock and other reactions. People are accustomed to call this pineapple allergic reaction as "pineapple poisoning" or "pineapple disease".
The main allergenic substance that causes "pineapple disease" is "pineapple prion enzyme". Salt water destroys the allergenic structure of the enzyme and makes it less toxic to individual people. Therefore, when eating pineapple, you can first peel the skin, remove the skin, and then cut in salt water soak, so you can reduce the occurrence of pineapple prion allergy.
