Can I eat half of a pear the next day

Half cut pears can generally be eaten the next day, but whether they have spoiled depends on the storage conditions. If refrigerated and sealed, it is usually edible. It is not recommended to consume it if it is left at room temperature or if it changes color or taste. After cutting open pears, they are prone to oxidation and discoloration when exposed to air. This is the result of the reaction between vitamin C and polyphenols with oxygen, which does not affect safety but may reduce nutritional value. The growth rate of microorganisms slows down in a refrigerated environment, and sliced pears that are sealed and stored overnight are usually still safe to consume. It is recommended to wrap tightly with plastic wrap or place in a sealed container to reduce contact with air. If more than half of the flesh turns black, the texture becomes soft and oozes juice, or emits a sour smell, it indicates that a large number of bacteria or mold have grown and must be discarded. Cut pears stored at room temperature for more than 4 hours have a higher risk, especially in high temperature and humid environments during summer. Pears have a high sugar content and sufficient moisture, providing favorable conditions for microbial growth. When furry plaque or mucus appears on the surface, it may have produced mycotoxins such as penicillin, and even if the deteriorated part is removed, there is still a safety hazard. Children, pregnant women, and immunocompromised individuals should avoid consuming overnight cut fruits to prevent the risk of gastroenteritis or food poisoning.

Daily recommendation: Cut and eat according to the amount consumed, refrigerate the remaining portion as soon as possible, and consume within 24 hours. Before consumption, check for any unusual odors or colors. If there is slight oxidation, the surface can be peeled off. Soaking in lemon juice can delay browning, but cannot inhibit microbial growth. Keeping the cutting board clean and avoiding contact with raw meat can reduce the risk of contamination. If symptoms such as diarrhea and vomiting occur, seek medical attention promptly.
