First: Pineapple must be soaked in salt water for at least 30 minutes. This fruit is very easy to cause allergies, mainly because pineapple contains a substance called bromelain, which is the culprit that causes some people's allergies. If there is pineapple allergy, there will be itchy skin, flushing, dizziness, vomiting and nausea, and even some people will have numbness in their mouths. Therefore, when dealing with pineapples, we should peel them first, and then soak them in light salt water.

According to scientific research, bromelain, which is easy to cause allergies, can be dissolved in light salt water. Therefore, soaking in light salt water for 30 minutes can clean up the substances that are easy to cause allergies in pineapples, and the light salt water can also remove the astringency and sour taste of pineapples and make the taste of pineapples more sweet. Therefore, it is very necessary to soak pineapples in light salt water.

Some people may not be allergic to pineapple, so it is unnecessary to soak pineapple in salt water, but even if they are not allergic to pineapple protease, this substance is not good for people's health. If pineapple prion is ingested, it is easy to decompose protein in the body. Protein plays a very important role in people's health, and this substance can also cause irritation to the mucous membrane in the mouth, so it is prone to tingling when eating pineapple, so it is very necessary to soak pineapple with light salt water.

Second: the pineapple should be soaked in water until it is translucent. In fact, the longer it is soaked, the better the taste will be. When the pineapple is first soaked in salt water, it will make the water turbid. This process is actually cleaning. After all, there may be some bugs in the pineapple. The light salt water can kill all the bugs and soak out some stains. So when it is first soaked, the pineapple water is likely to become turbid. At this time, it is necessary to change the water for the pineapple and soak it for two or three times until the water becomes translucent.

Moreover, although soaking pineapple can remove bromelain, it doesn't mean that pineapple can eat a lot. This kind of fruit that is easy to be allergic must be moderate. If you eat too much, even if it is soaked in salt water, it may still cause allergies. Moreover, it will damage the oral mucosa and affect oral health. Therefore, although pineapples are delicious, they should be eaten in moderation. Under normal circumstances, it is completely enough for one person to eat a quarter of pineapples at a time. Therefore, when buying pineapples, it is recommended to buy them in small portions. The amount of one pineapple is suitable for a family of three, so don't eat too much.
