A sliced pear can be eaten after a few hours

Cut pears should be stored at room temperature for no more than 2 hours, and refrigerated storage can be extended for consumption within 24 hours. Pear slices are susceptible to microbial contamination and oxidation, and their storage time is affected by factors such as temperature, humidity, and tool cleanliness.

Cut pears will rapidly oxidize, discolor, and breed bacteria at room temperature, especially in high temperature and high humidity environments where the deterioration rate is faster. Wrapping the incision with plastic wrap or soaking it in diluted salt water can slow down oxidation, but it cannot completely prevent microbial growth. If the pear flesh appears sticky, odorous, or noticeably brown and soft, it indicates that it has spoiled and is not edible.

refrigeration can significantly extend the shelf life of sliced pears, but they need to be sealed to avoid cross contamination. Even if refrigerated for more than 24 hours, if the pear meat becomes soft or has an abnormal taste, it should be discarded. People with diabetes or gastrointestinal hypersensitivity should strictly control their eating time to avoid discomfort caused by ingesting spoiled food.

It is recommended to use clean knives and cutting boards when cutting pears, and consume or refrigerate as soon as possible after cutting. Check for signs of spoilage before consumption, and it is best for children and those with low immunity to cut and eat immediately. Pear chunks can be mixed with lemon juice or vacuum sealed for daily use, and paired with ingredients such as yogurt and nuts to enhance their nutritional value.
