Why do pineapples soak in water?

The ripe pineapple pulp is golden yellow, and the juice is nutritious and has a special sweetness. However, when people eat it, they must cut it into small pieces and soak it in salt water for a while before eating it. Why?

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.

Salt can inhibit the activity of pineapple enzyme. Therefore, when we eat fresh pineapple, it is best to soak it in salt water for a period of time, which can inhibit the stimulation of pineapple enzyme on our oral mucosa and lips, and at the same time feel that pineapple is sweeter.

Mushroom is a protease, which can decompose protein. Therefore, a small amount of food can stimulate appetite, but excessive consumption is harmful to human body and will cause gastrointestinal diseases. Therefore, eat in moderation.

The astringency of pineapple comes from the fact that pineapple contains biological glycoside and pineapple egg enzyme. The content of this enzyme is high in immature pineapples, because pineapples that are easy to transport and pick are relatively raw. In the southern pineapple producing areas, people don't need to soak in salt water when eating fully ripe pineapples.

Feeling the astringency of pineapple is actually an allergic reaction to pineapple enzyme. It gives people a different feeling, some people feel astringent, some people feel "sore throat", and some people feel something else. Even nausea and vomiting, abdominal pain and diarrhea, numbness of mouth and lips, itchy skin and other manifestations.

Salt water can destroy this biological enzyme and make pineapple taste better. Another method is to heat the pineapple, which can also destroy the pineapple enzyme.

In addition, a proper proportion of salt water and the sweetness of pineapple form a "compound taste", which will make the taste of pineapple more perfect.
