1, pineapple needs to be soaked in salt water before eating. Pineapple contains a protease, which can make people allergic and even have shock symptoms, so pineapple should be soaked in salt water before eating.

2. Eat pineapple pulp directly, because pineapple contains bromelain, which will decompose protein, stimulate oral mucosa, and produce numbness and tingling. Soak the pineapple with salt water in advance. Salt can inhibit the activity of pineapple enzyme and avoid oral discomfort caused by eating pineapple. In addition, the acidity of ripe pineapple decreased, the sugar content increased and the aroma became more intense.
