It is spreading, hairy, tendril-bearing annual vine reaching a length of several meters. Fruit is very large, smooth, ellipsoid to oblong, light green with irregular dark green-mottled stripes, sometimes covered with a white, waxy bloom, about 30 centimeters long. The flesh is white, yellowish, pink or red; crisp, soft and juicy. Seeds are compressed, sometimes red, usually black.

Fruit has a sweet, crisp, juicy and hydrating flavor. Its texture is mildly granular, but its roughly 90 percent water content makes for an overwhelmingly juicy fruit.

Watermelon seeds are crunchy, peppery and wholly edible. In fact, seeds contain excellent health benefits as it is rich in iron, potassium and other essential nutrients.

Water melon nutrition value and facts

  • Fruit extract has carbohydrates, proteins, amino acids, steroids, glycosides, flavonoids, tannins and polyphenols.
  • The skin contains a fixed oil, arachidic acid, and traces of copper.
  • The seeds contain oil, 15 to 45%, made up of glycerides of linoleic acid, oleic acid and palmitic and stearic acids.
  • The oil contains a small amount of phytosterol.
  • All parts of the watermelon – rind, flesh, and seeds – contain citrulline, a non-essential amino acid, which converts to L-arginine when eaten.
  • Seeds are a rich source of enzyme urease.

How to check Ripeness of Watermelon

To check the watermelon is ripe, follow practical “thud” test: raisethe fruit to your ear, and give a vigorous tap. The best of watermelons have a thudding, hollow sound to indicate juicy, dense flesh. Always pair the “thud” tap with its heaviness—the best watermelons should feel heavy for their size. Heavy fruits signal water-rich flesh as opposed to unappealing stringy, desiccated innards.

Try  “stem test too.” Find the small circle near the end of the fruit where it’s been snipped from the vine. If it’s brownish in color, it’s ripe. If it’s green, consider passing on the fruit.

Ripe watermelons vary in exterior colors, but all should have a lustrous sheen. The fruit should be firm with no obvious, large indentations. A few scratches are acceptable, but bruises and pock marks are not.

Check the bottom of the fruit: Most watermelons have a discolored “ground spot,” which indicates where it rested in the soil before picking. The best fruits have a creamy yellow color—if it’s white, the fruit may have been cut prematurely from the vine.

Storage tips:

Whole watermelons kept in a warm summer kitchen can last up to a week.

Refrigerated watermelons can last  up to two to three weeks at temperatures no lower than 55 degrees Fahrenheit—any lower, and the shelf life reduces dramatically.

Place plastic wrap over refrigerated cut melon halves: This will keep the watermelon from drying out and prolong its shelf life.

For optimal nutrient content, keep watermelons out of the refrigerator—according to a study , watermelons kept at room temperature had 40 percent higher lycopene levels and nearly 140 percent higher beta-carotene levels.

Watermelon Recipe Ideas and Uses:

Make hydrating watermelon juice by simply blending and straining the fruit. Try other variants with cucumber, grape, strawberry, ginger, lemon, mint, and pomegranate.

Make gazpacho by blending the pulp with cucumber, bell pepper, lemon juice, salt, pepper, cilantro, and avocado or olive oil.
