Watermelon can be called "the king of summer", refreshing to quench thirst, sweet and juicy, and it is a good fruit in summer. Watermelon contains a lot of substances such as glucose, malic acid, fructose, protein amino acids, lycopene and rich vitamin C, except fat and cholesterol. It is a kind of food with high nutrition, purity and food safety. The sugar content of pulp meat is generally 5- 12%, including glucose, fructose and sucrose. Sweetness increased with the increase of sucrose in the late ripening stage.

Melon pulp per100g contains 90-93g of water, 9.8g of carbohydrates, 29-39mg of vitamin C, and a small amount of protein, fat, minerals and other vitamins. The plant grows strongly or moderately, with thick stems, large leaves, light color and flat leaves. The fruit is round, oblong or oblong, spindle-shaped, with or without reticulation, with or without furrows. The skin of the melon is 0.3-0.5 cm thick, and the pulp is 2.5-4.0 cm thick, which is soft or crisp, juicy and fragrant, mellow or without aroma.

Extended data:

Li Chenzhong said that it is incorrect to say that the sweeter the fruit, the higher the sugar content and the higher the calorie. Because the sweetness of fruit is not only related to the sugar content, but also related to the type of "sugar" and the amount of acidic substances. The "saccharides" with nutritional significance contained in fruits mainly include monosaccharides (fructose, glucose), disaccharides (sucrose, maltose) and polysaccharides (starch).

Among them, fructose has the highest sweetness, followed by sucrose (composed of one molecule of glucose and one molecule of fructose), followed by glucose and maltose (composed of two molecules of glucose), and starch is basically not sweet.
