Apple is a kind of fruit that everyone likes to eat. It is rich in many vitamins and nutrients. But recently, a girl in Xiaoshan, Zhejiang Province accidentally found that the apples that were scalded with hot water could exude little red 'blood beads', which looks a little creepy. What's going on? Let's follow sihai.com to find out what's going on?
Xiaoshan netizen's "temptation of ugliness" Post said:
What's the situation of "blood bead" of hot apple?
Usually I like to eat fruit. The apples I bought are snake fruits. I woke up hungry at noon. 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; & hellip;
I was shocked! After cleaning, red & hellip & hellip will appear again;
Compared the bubble with the non bubble, the color is much lighter.
Do you understand me? What's the situation?
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?
Degradation of anthocyanin
A casual search on the Internet shows that many netizens across the country have made similar 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.
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.
