Why does eating too much pineapple cause a tongue ache?

Because kiwifruit is rich in proteolytic enzymes, it is not the reason why it is not washed, just like the corners of the mouth will hurt if you eat too much pineapple.

Because pineapple contains bromelain, an enzyme that causes pain in the tongue.

It is bromelain and some glycosides that are indeed the culprits of "numbness" when eating pineapples, but soaking in salt water will not inactivate this enzyme and protect the mouth.

Because bromelain activity is quite strong, it can remain active for a long time at room temperature, and the active temperature range can reach 40-60, so it can be retained during long-distance transportation until it reaches your mouth"Reckless"。

However, salts are indeed included in common protein denaturation reagents. However, it is not table salt (the main ingredient NaCl), the sodium element in sodium chloride is the main group metal, and its sodium ions are quite stable, almost no longer undergo any chemical changes, and cannot inhibit the activity of enzymes. What can directly cause the denaturation of proteases are some transition metals on the periodic table, such as Cu2+, Fe3+, Hg2+, etc.

When the salt solution of these transition metals encounters the enzyme, it will form coordination bonds with the enzyme, and these new chemical bonds will strongly affect the structure and morphology of the enzyme, so that it cannot bind to the target reactant, or cannot be deformed normally, or even replace the original metal ions in the enzyme, which is macroscopic as the enzyme "inactivated".

Therefore, if you want to eat pineapple without numbness, the best way is to heat it at a temperature of more than 60°C for a while, so that you can really eat it with peace of mind. Of course, due to the pH activity range of the enzyme, it is also possible to use vinegar to bubble, provided that you can accept the taste.

Question 1: Why is the tongue numb after eating pineapple The pineapple pulp also contains a "pineapple enzyme (méi)", which has a special effect on our tongue and oral epidermis, while table salt can control the activity of pineapple enzyme, so if we eat pineapple pulp that has not been dipped in salt water, there will be a slight numbness and tingling sensation in the mouth, tongue and lips, which is the role of enzymes.

If your tongue is numb after eating pineapple, you can help relieve the discomfort by drinking salted water.

Because light salt water can inhibit the activity of bioglycosides in pineapple in the oral cavity and reduce its impact on the oral mucosa, after eating pineapple tongue numbness, you can rinse your mouth by drinking salt water to help relieve the numbness of the tongue.

Drink milk If your tongue is numb after eating pineapple, you can help relieve discomfort by drinking milk. The tongue is mainly protein, and pineapple contains proteases that can break down proteins, so the tongue is numb after eating pineapple. The protein content in milk is extremely high, and drinking milk can help reduce the chance of pineapple enzymes breaking down the protein on the tongue, increasing the chance of breaking down the protein in milk, so as to relieve the discomfort of tongue numbness.

Question 2: Why does my tongue feel stinging after eating pineapple? Analysis:

Hello, this condition may be caused by the alkaloids contained in pineapple**.

Guidance: In this case, you can use light salt water to rinse your mouth, and at the same time take vitamin C appropriately to alleviate it, if you have numbness symptoms, you can use cyproheptadine, loratadine and other anti-allergic drugs for treatment.

Question 3: What should I do if I have a headache after eating pineapple because there is pineapple enzyme in it, which has the effect of decomposing proteins, and will ** mouth. Soaking it in salt water (about 5 15min) can inhibit the ** effect of pineapple enzyme.

A certain amount of pineapple enzyme can also increase appetite, but too much can cause gastrointestinal diseases. So you can't eat too much, and pineapple is more humid and hot.

Question 4: Why does the tongue feel uncomfortable after eating pineapple Because the ripeness of this pineapple is not enough, many people have this condition. A lot of pineapples are now pesticide prompted, not naturally cooked, eat a little less, it's fine.

Question 5: What should I do if I eat too much pineapple and have a headache I will be fine in a few days. Soak it in salted water before eating.
