apple is one of the most familiar fruits. It is rich in nutrition, sweet and sour, and delicious. So we all like it. A few days ago, the Netizens found that this common fruit had an unusual situation. What's the matter? Let's have a look with the small editor of sihai.com.
A girl in Xiaoshan finds out by accident
Apples scalded in hot water
It can exude little red 'blood beads'
It looks a little creepy
What's going on?
A few days ago, a Xiaoshan netizen posted on the Xiaonei app:
What's the situation of "blood bead" of hot apple?
I usually like to eat fruit. The apples I bought are snake fruits. I woke up hungry at noon just now. I wanted to eat the apples directly, but I was afraid of the cold. So I soaked the apples in the boiling water basin, and then I came back for lunch. The apples are as follows & hellip;
I'm shocked! After cleaning, there will be red & hellip;
Compared the bubble with the non bubble, the color is much lighter.
Do you understand me? What's the situation?
Nowadays, people pay more and more attention to food safety. It's a strange phenomenon that Apple will bleed after taking a 'hot bath', which naturally makes people associate.
Some netizens replied: 'is this dyed by unscrupulous businesses?' others said: 'is this apple waxing?'
Other netizens joked: 'Apple was killed by you, she was spitting blood & hellip; & hellip;'
What is the red liquid? Is it harmful to human body? Can Apple eat it?
Truth: Apple's' bleeding 'is a normal phenomenon
It is the degradation of anthocyanin at high temperature
A casual search on the Internet shows that many netizens across the country have had similar 'unexpected discoveries' and queries.
In fact, this "bleeding" phenomenon is normal. It is the degradation of anthocyanins in apple peel under high temperature.
The anthocyanins of Apple mainly exist in the peel, which is also an important substance for the formation of peel color.
Anthocyanin is a very important natural pigment, but it will be separated out after high temperature and cold storage. In general, apple with red color has higher anthocyanin content, so it is easy to precipitate.
'bleeding' has nothing to do with waxing
It's easy to identify if it's artificially stained
According to relevant science materials, if the apple is waxed, the skin color will change greatly and become very beautiful. Even if it is waxing, it is just to increase the brightness of the apple. No one can make red wax.
In addition, if it is artificially dyed, it is easy to fall off by hand before entering the water, which is also easy to identify.
In fact, in the south, very few people wash apples with hot water, and only a very few of them will encounter 'bleeding'. In the north, because of the cold weather, some people will soak apples in hot water, which is not surprising.
Xiao Kepu: some rumors about Apple
The news says that half a kilogram of wax can be scraped on the apple. Is it really OK?
The purpose of Apple waxing is to keep fresh (insect, bacteria and water loss prevention); the most commonly used palm wax and shellac are so-called 'natural products', which are also used in foods such as candy; the standardized use of food wax and the added ingredients do not cause safety problems.
This is not scientific.
In fact, as long as we eat, the digestive system will start to operate, and people's digestion and absorption functions are not limited by our definition of "work and rest time".
What we really need to pay attention to is not the time of eating fruits, but our own feelings. For example, if you were very full at the previous meal, you didn't feel hungry at all, of course, you didn't need to increase the extra 'burden'.
Tap water can't be drunk directly, and apples can't be eaten directly. Why can apples washed by tap water be eaten?
There is a big difference between washing Apple's residual tap water and drinking tap water directly.
The tap water in our country does not meet the standard of direct drinking water. Whether it is directly drinking tap water that has not been boiled or eating fruit that has been washed by tap water, the two ways may ingest pathogens. However, there are significant differences in the number of pathogens.
After the fruit is washed by tap water, the dust, pesticide and bacteria that were left on the surface can be greatly reduced, and the tap water that was left on the surface of the fruit can be ignored.
Apple peel is more nutritious. It's better not to peel when eating. Is it true?
Some nutrients in apple skin are indeed high, such as polyphenols, flavonoids and proanthocyanidins with antioxidant function.
But an apple skin is just a little bit. The amount of these nutrients consumed by eating the apple skin is very small, which will not play a significant role in health.
Apple is a fruit with more pesticide residues. In order to keep healthy, it's best to wash and peel the apple before eating.
