Why do pears rot in the late stage? Why do pear hearts rot

Why do bagged pears rot later?

After the pear rots, there is often an alcohol taste inside, that is, the microorganisms inside produce alcoholic fermentation, alcoholic fermentation is produced by anaerobic bacteria, only in the micro-oxygen environment inside is suitable for the survival of anaerobic bacteria, and the anaerobic bacteria in the high oxygen environment outside will not grow, so it is bad from the inside.

This can happen when pears are stored for a long time, especially after sunny days. This is mainly due to the fact that as the temperature rises, bacteria will gradually infect the heart of the pear from the handle, but the flesh of the pear will be infected more slowly and can still be eaten.

Most pears have black hearts because cracks appear under the pears, causing the pear core to be infected by bacteria and other microorganisms, but because there is also a protective layer between the pear core and the pulp, after this happens, the flesh is generally good, so such pears can be eaten. However, if the pear is left for a period of time after the black heart, it may cause the flesh to also be infected, resulting in spoilage, so the pear cannot be eaten, so for the case of the pear black heart, you need to see whether the flesh is spoiled or has a peculiar smell, if it is good, it can be eaten.

It should be caused by a long time and improper placement, which causes the pear core to be infected by bacteria and other microorganisms, but because there is also a protective layer between the pear core and the pulp, after this happens, the pulp is generally good, so such pears can be eaten.

Nowadays, fruits and vegetables are sprayed with pesticides, and after the fruits are picked, they have to be processed twice and stained with potion. That's all medicine.

The fruit is not easy to preserve, and the pear has a lot of water, because the core part of some pears has a small gap, which is caused by bacterial reproduction, and in severe cases, the whole will turn black.

After a long time, as for why you start in the middle, it is because the acidity and nutrient content in the middle are high.

This pear must have been stored for a long time, and it was not stored at low temperature, so it was broken in the middle. It's better not to eat it, it's not good for the body.

This is a bacterial infection, which seems to be called moldy heart disease, and you can't see anything wrong with it from the outside, and apples also have this condition.
