Second, the eating methods are different

2. How to eat pineapple: There is no "internal thorn" after selling the skin, and you don't need a knife to draw a ditch, so you can eat it directly.

Third, different tastes

1, pineapple taste: before eating, it needs to be soaked in salt water, otherwise it tastes sour. This is because pineapple contains a lot of organic acids and bromelain, which can hydrolyze protein and stimulate the tender epidermis of oral mucosa and lips. Soaking in salt water can inactivate bromelain.

2, pineapple taste: no need to soak in salt water, can be eaten directly.

Extended data:

Because pineapple contains stimulating glycosides and bromelain, it decomposes protein in the body and stimulates the tender epidermis of oral mucosa and lips. If you don't use salt water bubble before eating pineapple, you will feel paralyzed and tingling.

Therefore, the peel and thorns should be trimmed, and the pulp should be cut into pieces, soaked in diluted salt water or sugar water, and then eaten. After pineapple is soaked in salt water, it can effectively destroy the internal allergic structure of "pineapple prion", thus losing the ability to make people allergic and the toxicity to some constitutions.
