Why doesn't the salted pineapple "bite the mouth"?

Pineapple is rich in fragrance, sweet and juicy, and is known as the "golden fruit" in spring

What is the relationship between pineapple and pineapple

Pineapple has a long history of being cultivated and eaten as a fruit

According to legend, after the pineapple was introduced to Taiwan in the Qing Dynasty, because a cluster of leaves behind it resembled a phoenix tail, some people named it after the "phoenix came" in the idiom "youfenglaiyi"

There are many kinds of pineapples.

Zhang Xiumei, a researcher at the South Subtropical Crops Research Institute of the Chinese Academy of Tropical Agricultural Sciences, said that the "eyeless pineapple" is actually a variety that has been bred with different traits

Studies have shown that pineapple contains a variety of vitamins and dietary fiber, as well as protein breakdown alcohol, carbohydrates, calcium, sodium, iron and so on

The sweet and sour taste of pineapple can stimulate the secretion of saliva

There are tricks to picking pineapples

At present, pineapples are on the market in large quantities, and many people think that pineapples are the "golden fruit" that unlocks the spring

Zhang Xiumei reminded consumers that they can judge whether the pineapple is ripe by looking at the shape, color, and touching the skin, so as to buy more delicious pineapples

Depending on the size and appearance, small and medium-sized fruits are preferred for family consumption, about 0.

Look at the color and fragrance.

When you feel the hardness of the appearance, use your fingers to flick the fruit, the sound is clear, the pulp is fine and durable, the higher the degree of yellowing, the better the sweetness and flavor, it can be placed at room temperature for about a week, which is the first choice for purchase; if you play with your fingers, A dull sound means that the pulp is juicy and not resistant to storage.

In addition, it is best to buy pineapples that are peeled now, and try not to buy pineapples that have been peeled and placed in plastic bags for too long.

Eating pineapple is not just for soaking in salt water

Many people like to soak in salt water before eating pineapple, thinking that this can eliminate the irritation of pineapple to the mouth and avoid allergies

Zhang Xiumei introduced that the reason why pineapple can stimulate the mouth is mainly because it contains bromelain (protein hydrolase)

Unlike heavy metal salt, table salt is mainly composed of sodium chloride

Zhang Xiumei suggested that people with severe allergies can boil the pineapple, or soak it in boiling water for a few minutes, and then cool it down with cold water
.
Because the best active temperature of bromelain that causes allergy is about 45 ℃ - 50 ℃, high temperature can destroy its activity
