Ingredients of watermelon

Watermelons keep what their name promises: They consist of over 90 percent water and are therefore even suitable as thirst quenchers. Because they only have a few calories, those who want to lose weight are also allowed to eat. In terms of vitamins, watermelon contains, for example, vitamin C and provitamin A. The carotenoid lycopene provides the reddish color.

Origin and botany

The watermelon originally comes from the steppe areas of Africa. Already in the Egypt of the Pharaonic times, about 4000 years ago, they were cultivated. The watermelon is comfortable in hot and dry climates and grows in tropical and subtropical countries. Today it is grown in these countries around the world. The main producers of watermelons in 2017 were China, followed by Iran and Turkey.

The watermelons available in Germany mostly come from Spain, Italy, Greece, Hungary and Turkey. In winter, imports come from Central America and Brazil.

The watermelon (Citrullus lanatus) Just like cucumber and zucchini, it belongs to the cucurbit family. So strictly speaking it is a vegetable, not a fruit. The watermelon is an annual herb with pinnate leaves. The single flowers are light yellow and very small. The fruit itself is known as the armored berry because the one to four centimeter thick rind is quite hard. The flesh of the watermelons available here is mostly red.

There are many different types of watermelon. Seedless varieties are now also being bred.

Season and storage of the watermelon

In Germany, the watermelon is available fresh from June to September.

Watermelons can get very large, even weighing up to twenty kilograms. The fruits that are available in stores weigh between two and six kilograms, although smaller specimens are increasingly being sold in the supermarket.
