1, look at the appearance
Watermelon has bright appearance, uniform shape, clear lines and slightly wider line spacing. Touching the lines with your hands and feeling slightly sunken are ripe melons, which are very sweet to eat. However, if the surface of watermelon is dim and fluffy, and the distance between rows is narrow, it means that the melon is not ripe and there are more tendons in the flesh.
Step 2: Weigh by hand.
The same variety, the same size, choose the light one over the heavy one, the watermelon of the same size, the light one is the mature one, and the heavy one is the raw one. This is because the watermelon juice in the watermelon is gradually transformed into sugar with the sunlight during the growth process, and the weight will be reduced, while the raw watermelon is heavy to pick up, but it is not mature, sweet or delicious.
Step 3 play with your hands
Flick the watermelon skin with your fingers and hear a dull "bang", indicating that the duller the watermelon, the more ripe it is. When you clap your hands, you can feel the tremor, so the watermelon is ripe. Clap your hands without shaking, indicating that watermelon is immature or the skin is too thick. If you clap your hands, the watermelon is ripe and not delicious.
Step 4 look at melons and vines
The vines are thick, fresh and curved. The greener the vines, the fresher the watermelons. If the vine is straight, or the color has turned yellow, and the vine is withered or dried up, the melon is either premature or dead and stale.
5, look at the navel of the melon
Choose a melon with a small navel, not a melon with a big navel. There are depressions in the pedicel and navel, indicating that it is a cooked melon. On the contrary, watermelon is not ripe and sweet.
6. Specific elasticity
The skin of melon is thin, and it is fragile when pressed with fingers, which is a cooked melon; Scraping with nails will crack, and the melon will be soft and ripe.
