Can frostbitten apples be eaten

summary

When some people eat fruit, they will gouge out the rotten part and eat it again, thinking that it will be healthy. In fact, even if the rotten part of the fruit is cut off, the rest of the fruit has been passed into the bacterial metabolites through the juice, and even some microorganisms begin to breed, in which the mold can cause human cells to mutate and cause cancer. Can frostbitten apples be eaten?

Can frostbitten apples be eaten

Among the three types of injury, mechanical injury is the most common. For example, a bag of red and big apples is in the basket, and then it passes a path that is digging a ditch; or an apple with good appearance flies to the floor when it is washed and splashed with water. As a result, you can only face up to a bunch of big apples. Fortunately, such a collision does not cause much.

Under the condition of low temperature, the activity of superoxide dismutase (SOD) in Apple would decrease sharply, and the free radicals in Apple cells could not be removed in time. More and more free radicals will change the permeability of cell membrane and destroy cell structure. On the other hand, low temperature can improve the activity of pectinesterase, which can decompose insoluble pectin and soften Apple tissue.

An investigation by the Chinese Academy of Preventive Medicine found that the content of patulin in the normal parts of moldy apples was 10-50% of that in the moldy parts. The content of patulin in normal parts of apples may be as high as 3 mg / kg. In this way, it's safer to send moldy fruits to the dustbin.

matters needing attention

Different rotten fruits should be treated differently. Those rotten fruits caused by collision and freezing are still edible. As for those fruits that have gone bad due to mold infection, it's better to send them to the dustbin as soon as possible.
