If you soak too long, it may cause bacteria to grow. After all, the sugar content in pineapple is relatively high, which provides conditions for bacteria to grow. You'd better not eat again after soaking all night.
Try not to stay overnight. Pineapple is rich in sugar, which is easy to dissolve in water. Overnight will promote the growth of bacteria. After eating, it is easy to cause diarrhea, abdominal pain and other symptoms of physical discomfort, and it will also make pineapple bubbles soft, affecting the taste of food. Therefore, it is best not to soak pineapple overnight. If you can't finish eating pineapple, you can wrap it with plastic wrap, and then put it into the refrigerator for refrigeration. It is advisable to finish eating it within 2-3 days.
How about soaking pineapple in brine overnight
1. Pineapple will lose water due to osmotic pressure (see salt concentration for details).
2. For the same reason, sodium ion is passively transported in the cell membrane, and pineapple may become salty.
3. High concentration salt can prevent corruption, and pineapple is safer to eat.
Pineapple is rich in sugar, crude fiber, minerals and vitamins. It has the effect of reducing weight, beautifying, cleaning intestines and stomach, promoting blood circulation, and eliminating colds.
However, pineapple contains biological glycosides and bromelain, which will stimulate the oral mucosa and cause numbness of the lips, and bromelain will cause nausea and vomiting. Consumers suffering from periodontitis, gastric ulcer and oral mucosal ulcer should be careful to eat pineapple, because pineapple is an acidic fruit, which stimulates the gums and mucous membranes. Patients with stomach diseases will also have acid reflux in the stomach. Some people with allergic constitution will have nausea, vomiting, abdominal pain, diarrhea, numbness of lips, skin itching and other allergic reactions after eating pineapple, which is often referred to as "pineapple poisoning" or "pineapple disease".
The correct way to eat fresh pineapple is to peel the pineapple, remove the thorns, cut it into pieces or pieces and soak it in salt water, and then wash away the salty taste, destroy the bromelain to reduce allergens, and make the pineapple taste more sweet. Half an hour after dinner, eat pineapple soaked in salt water, which is delicious and nutritious.
