Refrigerating the cut watermelon is a good option since it won’t last more than a day if kept at room temperature. However, the quality and the nutritional profile of the watermelon will only degrade over time. 

Before refrigeration, make sure the rind is thoroughly washed and dried. This will keep the contamination levels at a minimum. 

Wrap the sliced watermelon in plastic and pop it in the fridge. Dee-seeded and rindless watermelon pieces can be stored using a resealable bag or an air-tight container.

You can also pour the blended watermelon into ice cubes and freeze it for later. Another option is to make watermelon treats using spices, fruits, and veggies and freeze them for later.

Though the bad effects are not known, it is recommended to avert from eating watermelons with a yellow fiber pulp and the glossy, polished-like pulp that smells sour. This phenomenon is attributed to the presence of lycopene. 

How to tell if the watermelon has gone bad?

Expiration date: Keeping track of the expiration date, especially the pre-cut watermelon, is very important to avoid food poisoning.

Presence of nitrates: Reject watermelons with a yellow rind and flesh that contains white stripes. The presence of nitrates is tested by adding watermelon pulp to a glass of water. 

If the water goes turbid, the test is positive. The water turns red under extremely high levels of nitrates. 

Color: The rind should have a pine green shade with or without stripes. Something is fishy if this is not the case.

Mold: Mold grows on the surface of the fruit flesh in the form of black, green, or white fuzzy spots or patches. This is a very obvious sign of spoilage.

Texture: Watermelon with wrinkled, gritty, dry, mushy, or slimy flesh is spoiled.

Color: Ideally the watermelon flesh should have a clear red or deep pink color. Varieties like Tendergold, Yellow Doll, Desert King, and Yellow Baby have a natural orange or yellow flesh. Apart from this exception, the presence of yellow, orange, or black color should indicate spoilage.

Smell: If the watermelon gives off a sour or vinegar-like smell, it is done for.

Taste: Sour-tasting watermelon is no good.

Hollow center: A hollow center indicates the overripeness of the presence of growth hormones.
