When buying watermelons, don't just listen to the sound, keep in mind "4 wants 4 don't want", all the watermelons you pick are sweet and juicy

It's hot, so it's the season to eat watermelon again, so today I met two little brothers who bought watermelon in the market. I had no intention of having a lot of affairs. Who knew that they were attracted by their conversations. The watermelon in my hand is definitely sweet, because the sound of the melon in his hand has a crisp sound of the dribble, and the other says that the one in his hand is sweet, because the sound of knocking is banging, and the sound of watermelon rises.

So I stepped into a few more steps and looked at it carefully, and then said that the watermelon in your hands was not good, because the watermelon was not just to be able to distinguish it through the sound, so I knocked it again, and I was more convinced of my judgment. Then What skills do I use? After reading it, you can understand.

1. Buy watermelon to listen to sounds

The most common method for choosing watermelon is to listen to the sound. So is the cooked watermelon sounding the sound of "Dang Dang" or a "bang" sound? Many people hold their own words.

The answer is: cooked watermelon will make a relatively stuffy "bang" sound when hitting, so many people say that watermelon that can make crisp sounds on the Internet is wrong. Because it is not familiar with the sound of watermelon with sound. When knocking on watermelon, the reason why different sounds make are mainly because the density of the watermelon pulp is different. The more crisp the sound when it is hit. On the contrary, the mature watermelon, the density of the flesh is relatively low, so the sound made when knocking is more stingy.

Although some watermelons are knocking, they make a boring sound. Why not buy it?

The reason is that knocking on watermelon not only to listen to the sound, but also feel the sense of watermelon. If the watermelon has obvious vibration, then this watermelon is not only cooked but also thin skin melon. There are three points: 1, making a relatively stuffy sound, 2. Watermelon has a sense of earthquake, 3. There are echoes of watermelon

2. Buy watermelon to see the color of melon skin

The watermelon is not familiar with. At a glance, the method of distinguishing "authenticity" is that the color and pattern of the watermelon peel can be basically judged to be inseparable.

The color of the mature watermelon skin is darker, and the texture on the melon skin is clear. Most of the skin of the watermelon is dark green, so if it is slightly lighter, it is best not to choose. At the same time, you can touch the watermelon skin with your hands. If it is smooth and brighter, it is cooked melon.

In addition, when we buy watermelon, we usually see a large large yellow part of the watermelon skin of watermelon. It is best not to do so watermelon because this color appears because of long -term contact with the soil. As a result, this kind of melon is not enough, because the sweetness and light of fruits such as watermelon have a lot to do. The longer the sunshine time, the more conducive to the accumulation of the fruit of the fruit. Secondly, this kind of melon is unevenly mature, and it is likely that the part of the sunlight is cooked, and the yellow part has not yet been cooked, and finally it tastes poor in taste.

3. Look at the pattern of melon skin

The texture of the watermelon skin is like our skin. It can fully reflect the state of watermelon [Say it is not a very appropriate metaphor, helping everyone to remember better. There are many wrinkles on the face, there will be old -age spots on the age, and the mature watermelon skin is wide and the pattern is clear and the pattern is clear. It also depends on the color of the watermelon leather texture. The melon leather pattern is wide, and the color is the best melon, which shows that its taste is good, water is sufficient, and the sweetness is high.

The science behind melon skin pattern

Many people know that the pattern of the melon skin is related to the ripening of the watermelon, but few people know why. In fact, this is mainly related to the cells of the watermelon epidermis. In the early days of watermelon development, the original epidermal cells of watermelon have no color differentiation. After a period of development, a pigment formation factor secreted by the vitamin beam spreads two sides of the vascular beam to form a form of changes, so a change occurs:

The cell wall pigment accumulation of the cells in the form of the region, forming a dark structure [The prototype of the pattern] -, for a period of development, the cells with dark green cell walls induced adjacent cells into intermediate green cells [pattern changes change changes Process], and then passed through a long stage of development.

Until many times after filament division, the middle green cells gradually increased, and the cells with green cell walls also began to divide, forming a completely dark green cell. Finally In color, the width of the texture is formed by the cells of the watermelon epidermis for a long time.

Therefore, the texture of watermelon is more like the annual wheel of trees, which can identify the age and maturity of watermelon through the lines.

4. Look at the cord of the watermelon, melon vine

Watermelon's melon vine can fully judge the freshness of watermelon to avoid picking up to "bran". The newer the Guato indicates that the shorter the picking time, the better the taste.

The mature and high -quality watermelon Guati should have the following characteristics:

1. Gourd and vine color: If the color is yellow, it means that it is not fresh, do not buy it.

2. Plenty of water and vine water: If Guati is relatively dry and withered, it means that water loss occurs after the picking.

3. Gourd vine shape: If the melon vine is curved and the roots are thick, the head is thin and the melon is cooked

4. The depression of Guati and Gua umbilicals is full and full of surroundings, which shows that it is cooked melon. On the contrary, the melon vine is straight, and the thickness of the first and tails is almost the same, indicating that it is raw melon, so do not buy it. 5. Watermelon with similar sizes, hold the watermelon with your hands, first choose the heavier, the lighter watermelon should not be selected.

[Inappropriate metaphors, help everyone remember: adults' faces are all corners, and children's faces are almost not open, which is relatively rounded]

At the end: There are many skills to choose watermelon, but if you want to buy sweet and juicy watermelon, you should use a variety of methods to comprehensively identify, not to determine a method to determine the quality of watermelon. Any single identification There are errors in the method of ripening watermelon, but the use of various methods can greatly improve accuracy to avoid buying raw melon eggs.
