Is there a scientific basis for choosing watermelons according to shape, color and texture?

There is no scientific basis for choosing watermelons based on shape, color, and texture. The selection of watermelon is mainly based on the freshness of the melon vine and the freshness of the melon vine. Only by grasping these two can you pick out a large and sweet watermelon.

Look at the freshness of the melon vines

After choosing the variety, it depends on the freshness of the watermelon. Don't choose a watermelon with a dried vine (fruit stalk), the dried melon vine means that the watermelon has been picked for a long time. Although watermelons can be stored for a long time, watermelons that have been too long are still in danger of spoiling.

There is also a saying that you can weigh the amount of watermelon, if the melon vines of similar size are also fresh watermelon, it is better to choose a lighter one. "Heavy" means that this watermelon has a higher water content, and a high water content means that the sugar content is diluted. In the case of the same variety of origin, choose those lighter ones to ensure that you get sweet watermelon.

Of course, the lighter the better, if the weight of the watermelon is too light, it means that the melon may be overripe, and such a watermelon is greatly discounted in terms of taste and flavor.

Clap to hear the maturity

Well, finally come to the point of picking watermelons, that is, to shoot watermelons, and you can know the ripeness of watermelons by feeling it. After consulting the data, I found that this percussion experiment is really the most scientific method to test the ripeness of watermelon without damage.

Such a phenomenon exists for watermelons at different stages of growth. In the early stage of fruit development, the cellulose in the watermelon pulp (placenta in botany) will be relatively developed, which can play a role in supporting the fruit morphology. If we take a bite of the tender watermelon, I am afraid that it will have a pliable texture.

When the fruit is ripe, under the action of cellulase, the cellulose in the watermelon fruit is degraded, and some cells even break away from the cellulose network and become scattered cells, which is also the reason why the ripe watermelon has a "sandy" taste. This change in morphology affects the change in continuous vibration during percussion.

As the watermelon continues to ripen, its vibration time becomes longer, the vibration attenuation becomes slower, and the symmetry increases. A simpler way to tell the difference is that as the watermelon matures, the frequency of the vibration gradually decreases, that is, the sound of the knock becomes more and more muffled.

The circle at the bottom of the watermelon is the mark left after the corolla falls off, and it is not directly related to the sugar content. The watermelon will be very sweet if it is neatly textured, and the watermelon with the winter melon pattern will be very sweet, which can only be said to be good-looking, and it has nothing to do with whether it is sweet or not. The watermelon head, which is the so-called pedicle head, that is, the vascular bundles are tough, straight and curved, and the carbohydrates sent into the watermelon are the same.

It should be clarifiedThe quality of a watermelon is fundamentally determined by genes, and popular varieties on the market, such as Chunhongyu, Jin Xiaofeng and other watermelon varieties with personality are obtained by horticulturists for a long time, and from the beginning of their seed germination, there is a higher chance of producing watermelons with higher sugar content and more water.

Of course, in today's increasingly "industrialized" cultivation of agricultural products, the selection of seeds is becoming more and more homogeneous, and there is no difficulty in selecting local watermelon varieties more than 20 years ago.

I think there is, because the growing environment of watermelon determines its shape, color, and texture.

There is a certain basis for this, because if the degree of maturity is different, then the appearance of the expression is also different.

There is indeed a saying that watermelons can be selected based on their appearance.

You have a certain reason, you can see the color and texture of the watermelon, the intensity of the watermelon's light reception, and the intensity of the light to judge the sweetness of the habit.

Of course, there is a scientific basis, and these are used to judge whether the watermelon is ripe and whether there is a regulator.

In this case, there is no scientific basis, and this method cannot distinguish between good and bad watermelons.

There is a scientific basis, after all, these symptoms of ripe melons are judged by the appearance and shape of watermelons.

I think it still makes a lot of sense, after all, there are still differences in the appearance of different environments.

In fact, there is not much basis for this, so there is no scientific basis.

How to pick a watermelon1. Listen to the sound and slap the watermelon with your hands, if the sound is very clear, it is a ripe melon 2. Look at the melon umbilical circle, the smaller the umbilical circle, the better! The smaller the watermelon, the sweeter! Otherwise, it's not sweet!

Hello dear! The appearance characteristics of watermelon include the following aspects:

1.Shape: Watermelons are generally oblong or oval in shape, with slightly sharp ends and slightly swollen in the middle.

2.Size: The size of the watermelon varies depending on the variety, but it is usually between 20 and 30 cm in diameter and between 2 and 10 kg in weight.

3.Color: The skin of the watermelon is dark green or light green, and there are green stripes or spots on the surface of the canopy, and some varieties may also have yellow or white skin.

4.Pattern: The outer surface of the watermelon has distinct longitudinal stripes, which are made up of green and dark green bands, and the pattern varies from variety to variety.

In general, the appearance characteristics of watermelons are relatively distinct, so we can preliminarily judge the variety, quality and ripeness of watermelons by observing their appearance.

1. Generally, when the vines on the melons are picked, the melon farmers will keep them, which can make the watermelons easier to store, so the melon farmers will not cut off the part on the edge of the melon vines. Let's check the melon vine first, if the whiskers next to the melon vine are dry, it proves that the watermelon is naturally ripe and can be bought, if it is green, it is recommended not to buy, most of the vertical rot is 5-6 ripe, and the taste is not very sweet.

2. Let's take a look at the texture of the melon, if the texture is uneven and there are segments, it is recommended not to buy. If the texture is uniform and there are no broken lines, you can buy it. (Generally speaking, sweet watermelons have bright colors and distinct stripes.)

If the watermelon is foggy and broken, it is probably not a good melon. ）

3. Let's take a look at the umbilicus of the melon, it is recommended to buy a small umbilicus, and do not buy a large umbilicus. (The smaller the navel of the watermelon, the better, such a watermelon is not only thin but also sweet.) The larger the navel, the thicker the skin of the watermelon, the less edible melon flesh, and the taste is poor).

4. In addition to the above tips, the most common trick is to shoot watermelon, listen to the sound of watermelon, if the sound is crisp and loud, it is recommended to buy, if the sound is muffled, it is recommended not to buy. (Ripe melons will make a "bang" sound, while raw melons will make a sound similar to "dangdang", and if it is overripe, the watermelon sound will make a "poof" sound.) ）

5. The last trick is to look at the overall shape of the watermelon, if the two ends of the watermelon are uniform, not one big and one small, it is recommended to buy, otherwise it is not recommended to buy.

6. This is the watermelon I selected with the above skills, and the taste is really sweet. When I eat watermelon, I like to cut it into small pieces in the picture below, so that it is easy to hold and eat.

Many friends ask why the seeds are still white after the watermelon is ripe?

Those white seeds are not actually seeds, they are only germs at best. For the fruit of a watermelon to grow, it must first bloom, pollinate, fertilize and set seeds. However, such growing conditions require a temperature of more than 25, and when the early-maturing watermelon is planted in the greenhouse in early spring, the temperature is relatively low, and the watermelon is difficult to flower and pollinate normally.

To this end, melon farmers will apply a small amount of synthetic plant growth regulator on the stalk of the young flowers of watermelon in early spring to assist watermelon flowering and fruit setting, this technology is called artificial auxiliary melon seat technology. In this way, the seeds of the melon will be white. White-seeded watermelon has no problem with food safety at all, and it has no effect on human health.

Friends, you pick up the loss, when choosing watermelon, you can not look at the texture to judge the quality of the melon, but should listen to the sound gently knock on the skin of the watermelon, if the sound is more crisp, it means that the watermelon is better in color, and it tastes sweeter.

When choosing a watermelon, you can distinguish whether it is ripe according to the texture, the texture is clear, and the circle at the bottom of the watermelon is concave, so the watermelon is ripe.

Choose a watermelon to see the texture, first look at the texture color is darker, then look at the texture from the head of the melon evenly distributed, and finally knock on the watermelon to listen to the sound to find the feel.

When picking watermelons, look at the depression at the guati, it is a wild ripe melon, and vice versa. Second, the texture is clear and clear, the color is relatively dark, and it is a ripe watermelon that is not pressed on the hand of Zhiqing ruler.

When choosing a watermelon, look at the texture, the texture is dense and even, and the color is relatively dark, and the umbilical concave at the bottom is relatively deep, which is a very familiar habit.

The texture is wide and clear, and the melon seeds are less ripe and better.

When choosing a watermelon, look at the texture of the sail to see the growth of the texture, as well as look at the depth of the color of the watermelon, the most important thing is to pick the melon hall when the hall is old, knock on the watermelon, listen to the sound inside the watermelon to judge whether he is full of water, or less water, or the loser is in a mature period, or a stiff period.

How to look at the texture when you are elected watermelon, this is very simple, you have to pick the watermelon first, if he is hollow wall, it means that this orange lead watermelon is very good, and if he is ripe If there is no business, it means that his watermelon is not ripe, and he has played just erythrocin, so if you eat it, it will be very bad for the body.

1.The smaller the bottom of the watermelon, the thinner the skin and the better it tastes.

2.Judging from the color of the watermelon skin, the blue-green one is a good melon, and the hazy one is not a good melon.

3.Watermelon head is generally delicious in the case of a few troubles, and don't buy a straight line.

4.The neatly striped family Bi Ji is a good omen

When choosing watermelon, be sure to see the texture thoroughly, and uh, this bright watermelon tastes very delicious.

The width of the watermelon texture directly determines its taste, so check the watermelon with wide lines is delicious, or the narrow lines are good losers to dig and eat it, let's listen to what melon farmers say. In fact, a delicious watermelon, you can't choose a wide texture, nor a narrow texture, but to choose the kind of width and narrowness, the texture is clear, and it is the kind of deep and shallow stripes, the shallow stripes are best slightly wider, four or six points are the best.

Pick watermelon, sometimes you don't need to look at the pattern, you just need to knock the watermelon, knock the watermelon twice, and the delay is. The watermelon is good and especially delicious when the hand land time is very loud. You can go and give it a try.

How to look at the texture when choosing a watermelon, this is a good return to the watermelon, you take it lightly, the hollow inside is to think about this watermelon, it is very good and very sweet, and it is also ripe, and his kind of watermelon is also very crisp, eat it.

Choose a watermelon to see the texture, first look at the texture or cover the color is darker, and then look at the texture from the head of the melon to distribute evenly, and finally knock on the watermelon to listen to the sound of filial piety to find the feel of the skin, decide whether the watermelon is good.
