Cut open pumpkins can generally be stored in the refrigerator for 3-5 days, while intact and uncut pumpkins can be stored for 1-2 months. The actual storage time is affected by factors such as storage method, maturity, and refrigerator temperature.
When storing pumpkins in cold storage, they should be tightly wrapped in plastic wrap around the cut surface or sealed in a box to avoid moisture loss and flavor mixing. Mature old pumpkins are more resistant to storage than tender pumpkins due to their high starch content and thick skin. Maintaining a refrigerator temperature below 4 ℃ can effectively inhibit bacterial growth, and frequent temperature fluctuations caused by opening and closing the refrigerator can shorten its shelf life. If the pumpkin is soft, moldy, or has a sour taste, it has spoiled and is not edible.
Storing intact pumpkins in a cool and ventilated place is more beneficial for extending their shelf life than refrigeration, but they must be refrigerated after being cut open. Under high temperature conditions in summer, the refrigeration time for intact pumpkins may be shortened to 2-3 weeks. Pumpkin can be frozen for 8-12 months, but its texture will soften after thawing, making it suitable for making pumpkin puree or soup.
It is recommended to choose the appropriate size of pumpkin according to the consumption plan and avoid repeated cutting. Before storage, check if the skin is intact and undamaged. Cut open pumpkins should have their seeds removed before refrigeration. Pumpkin is rich in β - carotene and dietary fiber, and proper consumption will help protect eyesight and intestinal health, but diabetes patients need to control their intake. If there is any mucus or odor on the surface of the stored pumpkin, it should be discarded immediately.
