How can watermelons be kept fresh for a long time? – Watermelon’s sweet and juicy red flesh is high in vitamins, minerals, and lycopene, all of which are helpful to health.
A whole watermelon may be preserved in the refrigerator for about 2 weeks, but only about 1 week at room temperature.
Wrap the sliced side of a watermelon securely in plastic wrap and set it in the refrigerator.
Plastic wrap may be securely wrapped over the chopped watermelon to create a seal against smells, air, and germs.
Practice has shown that if the chopped watermelon is covered in plastic wrap and stored in the refrigerator for 4 to 5 days, its look, flavor, and freshness will not alter.
In reality, the combination of plastic wrap and low temperature may successfully extend the shelf-life of watermelon by retaining moisture and sealing in freshness.
