Why should pineapple be soaked in salt water?

Pineapple is a fruit that everyone has seen, and many people have eaten pineapple, but everyone may know that when eating pineapple, you usually peel it and soak the flesh in salt water before eating it. So why do you need to soak pineapple in salt water? How long should it be soaked under normal circumstances? Today I will talk about these issues for you.

Why should pineapple be soaked in salt water?

1. Pineapple can irritate your lips

The pineapple fruit has high nutritional value. It contains a lot of malic acid and citric acid, as well as a variety of vitamins. In addition to these substances, pineapple also contains a lot of bromelain, which can decompose protein and stimulate the oral mucosa and lips, causing a feeling of pain and numbness. This bromelain loses its activity when it encounters edible salt, which is an important reason why people eat pineapples soaked in salt water.

2. Pineapple contains oxalic acid

Pineapple not only contains a large amount of malic acid and citric acid, but also contains some natural oxalic acid. After entering the human body, this substance will inhibit the body's absorption of trace elements such as iron and calcium. After oxalic acid is soaked in salt water, the acidity will be weakened, and the harm to the human body will be reduced accordingly. This is also one of the main reasons why people eat pineapples soaked in salt water.

3. How long is the best time to soak pineapple in salt water?

After peeling the pineapple, soak it in salt water for too short a time will not destroy the pineapple enzyme inside, and allergies will still occur when eating it. If the soaking time is too long, the nutrients in the pineapple will be lost and bacteria will be produced. Therefore, from a scientific point of view, soaking the pineapple in salt water for half an hour is the most reasonable time, and the longest time should not exceed one hour.
