How long can the unspoiled jackfruit keep

Unpeeled jackfruit can be stored for 3-5 days at room temperature and 7-10 days at cold storage. The actual time is affected by maturity, storage environment, skin integrity, temperature fluctuation, humidity and other factors.

1. Maturity

jackfruit with high maturity is more likely to breed microorganisms and cause corruption due to its high sugar and water content. When purchasing, gently press the skin to determine the degree of softness. Soft fruits should be consumed first. If the skin is green and hard, it can be placed in a cool and ventilated place for 1-2 days to promote ripening, but it needs to be checked daily to avoid overcooking.

2. Storage environment

jackfruit is sensitive to ethylene and should be away from apples, bananas and other fruits that release ethylene. The ideal storage environment should be dark, dry, and ventilated, with a temperature of 12-15 degrees Celsius being optimal. High temperature environment can accelerate the fermentation of fruit pulp, resulting in a wine flavor or rancidity phenomenon.

3. Skin integrity

When scratches or damages appear on the skin, bacteria and mold are prone to invade from the wound. During transportation, collisions should be avoided, and surface stains can be wiped with a dry cloth before storage. If local mold spots are found, the moldy area should be immediately removed and the remaining part should be consumed as soon as possible.

4. Temperature fluctuations

Frequent switching between room temperature and refrigerated environments can lead to the accumulation of condensed water and accelerate decay. If refrigeration is required, it is recommended to wrap it in kitchen paper and put it in a fresh-keeping bag to avoid direct contact with the inner wall of the refrigerator. After being taken out of refrigeration, it should be consumed within 2 hours.

5. Humidity Control

High humidity can easily cause mold growth, while low humidity can lead to skin wrinkling. Food desiccants can be placed in humid areas in the south, while slightly damp towels can be used to cover dry environments in the north to maintain humidity. The flesh that comes into contact with air after cutting will quickly oxidize and needs to be tightly wrapped in plastic wrap and refrigerated.

During the storage of complete jackfruit, it is recommended to check the skin every day for depression, exudation or odor, which are early signs of corruption. If long-term storage is planned, the fruit pulp can be peeled off and packaged for freezing, but the taste will become softer after thawing. Before consumption, pay attention to observing whether the color of the fruit pulp is uniform, and avoid consuming black or sticky spoiled fruit pulp. For jackfruit that has been cut, it is recommended to eat it within 48 hours under cold storage conditions, and pay attention to the cleaning and disinfection of knives and containers to prevent cross contamination.
