If you seal the cut side of a watermelon properly, it can last for about 3 to 4 days in the refrigerator. Sealing the cut side helps prevent moisture loss and reduces the risk of contamination, which can extend the watermelon's freshness.
To seal the cut side of the watermelon, follow these steps:
Wash the watermelon thoroughly to remove any dirt or debris from the rind.
Use a clean knife to cut the watermelon in half.
Cover the cut side of the watermelon with plastic wrap or place it in an airtight container.
Make sure the plastic wrap or container is tightly sealed to minimize exposure to air and prevent moisture from escaping.
Store the sealed watermelon in the refrigerator at a temperature between 36°F to 40°F (2°C to 4°C).
By sealing the cut side and refrigerating the watermelon, you can enjoy its freshness for a few more days compared to leaving it exposed to air. However, keep in mind that watermelons are best when consumed shortly after cutting, as their texture and taste may degrade over time even with proper sealing and refrigeration.
