How long can pears be stored after being cut open

Pear slices can be stored at room temperature for 2-4 hours and refrigerated for 1-2 days. The storage time is affected by factors such as storage environment, cutting method, pear maturity, tool cleanliness, and sealing degree. After cutting open the pear, the oxidation rate accelerates, and the flesh is prone to softening and yellowing. Microorganisms are active in a normal temperature environment, and exposure to the cut surface for more than 4 hours may result in significant discoloration or rancid odor. refrigeration can delay spoilage, but it is necessary to tightly wrap the cut surface with cling film to reduce contact with air. Immature pears, due to their high content of tannic acid, undergo rapid browning after cutting. If the pear cutting tool or cutting board is not thoroughly cleaned, residual bacteria will accelerate the decay of the fruit flesh. Cutting with a ceramic knife, applying lemon juice to the cut surface, and vacuum sealing can extend the storage time. But if there is already mucus, blackening or odor on the cut surface, it cannot be continued to be consumed. Freezing storage can cause the taste of pears to deteriorate after thawing, and it is generally not recommended to use it.

It is recommended to control the number of cuts according to the consumption needs, and it is best to cut and eat immediately. If short-term storage is required, pears should be stored in a sealed box and checked for spoilage before consumption. Pears are rich in dietary fiber and vitamin C. Moderate consumption can help promote digestion, but spoiled fruits may cause gastrointestinal discomfort. When storing, it is important to observe freshness.
