Can a piece of black pear still be eaten

A piece of pear that has turned black, if not rotten, can usually be eaten. The black spots may be caused by bumps or low-temperature frostbite. If there is mold, odor, or soft pulp, it is not recommended to consume.

Local blackening of pear skin or flesh may be due to physical damage during transportation and storage, such as cell rupture, oxidation, and discoloration caused by collision and compression. In such cases, only the discolored parts need to be removed for safe consumption. Pears may suffer from frostbite in low temperature environments, with brown mesh patterns appearing on the internal flesh, resulting in a poorer taste but no toxicity. Some varieties, such as Korla fragrant pear, have brown fruit rust after maturity, which is a normal phenomenon. If the blackening of pears is accompanied by green mold spots, alcohol flavor, or wet, soft, and rotten flesh, it may be caused by mold contamination or bacterial growth. Moldy fruits may produce toxins such as penicillin, and even if the moldy parts are removed, there is still a risk of contamination. People with diabetes or people with low immunity should avoid eating suspicious fruit to prevent gastrointestinal discomfort or food poisoning.

When purchasing pears in daily life, be careful to handle them with care, and use a fresh-keeping bag to isolate moisture when storing them in refrigeration. Before consumption, observe whether the fruit stem is fresh. If the skin turns black, the surface layer can be peeled off. If the internal flesh is semi transparent with water stains or emits a fermented flavor, it needs to be discarded. It is recommended to store fruits in a ventilated and cool place, cut them open and consume them as soon as possible to avoid nutrient loss and microbial growth.
