1, look at the umbilicus.
Looking at the umbilical circle at the bottom of the watermelon, you can easily determine whether the watermelon is sweet or not. Generally speaking, the umbilical circle is small, round, and slightly concave watermelon growth time are more adequate, the fruit will be sweeter. Relatively, the umbilical circle is relatively large watermelon is not very sweet. So we remember, buy watermelon, look at the umbilical circle, pick a small umbilical circle, the best a little bit of depression.
2, shape.
First of all, look at the shape of the watermelon, deformed watermelon do not choose, such a watermelon is not only bad taste, and there may be problems. Then look at the color of the watermelon, choose lime green, the kind of fog white never buy, not sweet and delicious. Finally, look at the grain, the grain is clear and neat is a good melon.
3, look at the melon tip.
The melon tip is the root of the head of the watermelon, from the degree of curvature of the melon tip, you can determine whether it is a crop of watermelon or a second crop of watermelon. The first crop of watermelon is generally very curved, nutrients and light are more adequate, so the watermelon sugar content is high, sweet taste good. The second crop of watermelon is relatively straight, the flavor is not as good as the first crop of watermelon. So when we choose watermelon, it is best to choose a more curved melon, so that the more sweet and delicious.
4, listen to the sound.
To the watermelon in the hand, close to the ear, finger gently knocked the watermelon, if the sound of the thud of the crisp ringing sound, and the feeling of vibration to the melon means that it is a good melon, generally sweeter. If the sound sounds boring, and no vibration, such a watermelon is generally not fully ripe, not sweet and tasty, should not be purchased.
5, weighing.
Shape looks about the same size of the two watermelons, weighing the lighter watermelon ripeness will be better, on the contrary, the lighter the melon indicates that the lower the maturity. Because as the watermelon matures, there will be a large part of the water is, accumulate more sugar, so the weight of the mature watermelon is always a little lighter. So the same size watermelon choose light.
