Is it still edible when the pear heart is dark

If the pear core turns black and has not rotted or spoiled, it can generally be eaten, but it needs to be discarded when mold or odor appears. The blackening of pear hearts may be caused by oxidation reactions, low-temperature frostbite, or microbial infections. It is recommended to determine the appropriate treatment based on the specific situation. The oxidation reaction that occurs when pear meat comes into contact with air is a common cause of blackening of the pear heart. After cutting, polyphenolic substances in the meat come into contact with oxygen, producing brown substances. This situation only affects the appearance and can still be safely consumed after removing the discolored parts. Improper storage at low temperatures may cause damage to the internal cells of pears, resulting in browning and a decrease in taste in frostbitten areas, but there is usually no health risk. Some varieties, such as Korla fragrant pear, naturally appear brown around the nucleus due to their mature characteristics, which is a normal phenomenon.

Be alert to the blackening of pear hearts caused by mold growth. Mold may produce harmful substances such as penicillin, and even if visible mold spots are removed, there is still a risk of toxin diffusion. Moldy pears often have a sour or alcoholic taste, and white mycelium or sunken spots may appear on the skin. Ingestion may cause abdominal pain and diarrhea. Pears stored for a long time are susceptible to infection by microorganisms such as Alternaria, which can spread outward from the core and form black hearts. In such cases, it is recommended to discard the entire pear. Choose pears with intact skin and no mechanical damage when purchasing, and store them in a damp environment to reduce the probability of mold growth.

It is recommended to cut and eat pears for daily consumption to reduce oxidation. For short-term storage, soak them in light salt water or lemon water to delay browning. Wrap the cut area with cling film during storage and place it in the refrigerator's refrigeration layer to extend the shelf life. If a large area of blackening of the pear core is found, accompanied by texture softening, odor, or mold spots, it should be stopped from consumption. Pears are rich in dietary fiber and vitamin C. Moderate consumption can help moisten dryness and promote diuresis, but moldy fruits may be harmful to health and should be carefully identified.
