recently, the circle of friends has been swept by a “news” about Apple. It is said that a girl in Zhejiang used hot water to scald the apple. As a result, the apple exuded “blood beads”. Many friends asked, what’s going on? Is it the unscrupulous businessmen who dyed the color? Or waxed?

and

actually, as early as 2014, there were similar netizens on the Internet for help, and they also saw apple “blood beads”. However, at that time, the location was Wenzhou, and the protagonist was Fuji.

from two descriptions, and from the pictures provided by netizens, I guess that the possibility of this apple being dyed is very small, and it has nothing to do with waxing.

and

the reason why apples have “blood beads” is mainly because scalding will damage and rupture the epidermal cells, and the substances inside the cells will run out, including red anthocyanins.

and

cells are mainly composed of cell fluid, which contains sugar, pigment and a lot of water.

and

therefore, after dissolving, they are in the shape of drops of liquid. The reason why the droplets are red is mainly because there are pigments in the cell fluid, especially anthocyanins. In general, the content of anthocyanins is higher and the “blood drops” are more red in the red apples.

and

in fact, netizens in many places in China have had similar “unexpected discoveries” and doubts.

however, this usually happens less in the south, because of the high temperature in the south, few people wash apples with hot water.

but in the north, because of the cold weather, many people will use hot water to scald the apple before eating, which is more likely to encounter this kind of exudation “blood beads”.

warm tips: red apples with hot water will exude “blood beads” is a normal phenomenon, the possibility of dyeing is extremely low, and it is not likely because of waxing. Apples purchased in regular supermarkets can be safely eaten.
