Pineapple, the unique sweet aroma makes people can't help but salivate
However, after a few bites, it feels sour and mouthy
Therefore, the popular salt water soaking pineapple god operation
Have the same experience, after reading this article you will understand
regretful! Useless!
Pineapple the mouth for two most likely reasons.
(1) Pineapple contains bromelain, which can break down the proteins on our oral mucosa and produce a tingling sensation.
(2) Pineapple contains calcium oxalate crystals, which pierce our mouths like needles and produce a tingling sensation [1-3].
But whatever the reason, it's useless to sprinkle some salt in the water and take a dip.

The best way to really not "prick" is to boil water for a few minutes, because hot water can inactivate bromelain or dissolve calcium oxalate [4-5].
As for pineapples that some people think are soaked in brine, they are not so astringent, but only the synergy of taste: salty taste can weaken the bitterness, can make the sweetness stronger [6].
When Japanese people eat watermelon, they are accustomed to adding some salt, which is a similar principle.

Not really.
Each 100 grams of pineapple contains 18 mg of vitamin C[7], ranking 17th among common fruits and one medium-sized fruit.
Winter dates are 13.5 times its size and kiwi fruit is 3.4 times its size.
Obviously, pineapple is not the first choice for vitamin C supplementation.
And pineapple's other nutrients are not prominent. Pineapple just wins in taste, nutrition does not have much hope!

Originally born of the same root, but the name is different.
In fact, pineapples are pineapples, and pineapples are pineapples, and they belong to the bromeliad genus of the bromeliad family [8].
Pineapple is the scientific name, pineapple is commonly known, as for what pineapple is better than pineapple, it is completely a concept hyped out by merchants.

Not really.
Although bromelain has the effect of promoting protein digestion, it is also a protein itself, when we eat pineapple, bromelain in the human body under the action of pepsin will be inactivated, so pineapple to promote digestion may only be a psychological effect.
However, pineapple is stewed with meat, and bromelain helps break down the protein in the meat and makes the meat more tender. Give it a try!

The rumors of the rivers and lakes will never be finished.
It is rumored that eating pineapple will make sperm "sweeter", which is purely a rumor, and there is currently no scientific evidence that eating pineapple can make sperm "sweeter".
Don't really have this fantasy anymore!
In short, pineapple (pineapple) is just an ordinary fruit, eat it is good to be happy, don't think about the rest.
