Watermelon can be called "the king of summer", which is cool and refreshing, sweet and juicy, and is a good fruit in summer. Watermelon contains a lot of glucose, malic acid, fructose, protein amino acids, lycopene and rich vitamin C besides fat and cholesterol. It is a kind of food with high nutrition, high purity and safe eating. The sugar content of pulp is generally 5 ~ 12%, including glucose, fructose and sucrose. The sweetness increased with the increase of sucrose in the late mature stage.
