How to distinguish a good watermelon? How can you tell the difference between watermelon?

Step 1: Look at the colors. The surface of the melon skin is smooth, the pattern is clear, the texture is obvious, a little yellow, and there is no fluff is a ripe melon. There are fluff on the surface of the melon skin, the texture is not clear, the pattern is not clear, and the green melon skin is a raw melon.

Step 2: Listen to the sound. Drag the watermelon with one hand and flick it lightly with the fingers of the other, or gently pat the watermelon with your fingers together. Hear the crisp sound of bouncing for ripe melons. Hearing the heavier sound of kicking is raw melon.

Step 3: Look at the head and tail. The watermelon is symmetrical at both ends, the top of the melon is deeply concave, and the head and tail are the same size as the ripe melon. The head is large and the tail is small.

Tips for picking watermelon How to pick watermelon How to choose watermelon is a must-have trick for summer.

Step 4: Specific elasticity. The melon with a thinner skin and easy to crush with fingernails is a ripe melon. Pinch the skin of the melon with your fingers, the skin of the melon is too soft is the overripe melon, and the one that can't be pinched is the raw melon.

Step 5: Look at the bottom of the melon. The bottom of the melon is green and ripe, and the base of the melon is dark brown, yellow, and wilted is the melon that is not ripe and picked. The bottom of the melon is withered, and it is a dead melon.

Step 6: Use your hands to flip. Hold the watermelon in both hands and throw it upwards, and catch it when it falls. The watermelon feels not very heavy when it falls in the hand, and the ripe melon with a sense of empty floating, and the raw melon that falls very heavy and sinking in the hand. <>

Look at the merchants. Let's see if this melon stall is always here! This means that he has good purchase channels and sales channels, which can ensure that watermelons continue to be purchased and sold, and there is no smashing stall due to the abduction and closure of the pit.

Of course, there are no above troubles in buying watermelons in supermarkets, whether it is a large or small supermarket, it is not a one-shot deal, but the watermelons in the supermarket have always been more expensive than those in the market or on the street, and the freshness is also poor, which is something that everyone on the earth knows.

If you go to a market, then choose the one with the most watermelons to buy, commonly known as "a large number of spots", it is best to have a whole vehicle of watermelons in the **pestle, you can choose at will.

Look at the product. Regardless of the watermelon, whether it is large or small, round or square, seeded or seedless, red or powder, white, yellow, green, purple, watermelon has a green skin, to see whether the melon skin is fresh is the first step in choosing watermelon, the key point is to look at the texture of the watermelon skin, generally speaking, the watermelon skin is composed of two kinds of deep and shallow lines, whether it is deep or light lines, relatively neat and clear is one of the standards of a good watermelon, three, look at the melon "pull".

If Guati is the North Pole of watermelons, then "Pulling" is the South Pole of watermelons.

This is a place where the three flowers gather, and the threads on the watermelon are gathered here. In fact, this location is the key to determining the thickness of the watermelon skin.

Personal experience shows that the watermelon skin is thicker and the watermelon skin is thinner, according to the experience of the sprinkler, the position of the watermelon that is larger is usually more inverted, and the smaller one is usually not so large, and some are even a little convex, well, a little lordosis and kyphotic association. <>

Ripe melon: the skin color is gray, the appearance is lubricated, the pattern is clear, and to pick a round watermelon, if the shape of the watermelon is concave and convex, it is not recommended that everyone choose, this watermelon is mostly the use of ripening agent, bulking agent cultivated, it tastes light and tasteless.

2.Look at Guati.

Raw melon: Guati is straight.

Ripe melon: The melon of the ripe melon is curved, if the melon has withered and fallen, it is too long, and such a melon is not recommended to choose.

3.Look at the watermelon navel:

Raw melon: The umbilicus is concave and shallow, and it is thicker.

Ripe melon: the umbilicus is concave deeply, the melon navel is round and relatively small, when choosing watermelon, it is also very important to look at the navel, be sure to choose the round, round melon navel watermelon is the sweetest. If the navel of the watermelon is crooked or irregular, it is best not to buy it, it is likely to be ripe, even if it is sweet, it may be gammelin.

4.Pick up the watermelon with your hand.

Raw melon: After holding up the watermelon and patting it, the melon without ** is a raw watermelon.

Ripe melon: hold up the watermelon with one hand, play the melon with the other hand, the hand of the melon feels that there is a ** is the ripe melon, usually when buying the melon, it may be encountered, a pat of the melon will crack, this time must be bought this watermelon, don't feel that the crack is not good, shoot it to crack, prove that the watermelon is very crisp, are crisp to this level, then it must be very sweet to eat, this is the real ripe watermelon.

5.Tap the watermelon with your fingers.

Raw melon: The loud sound of playing watermelon is raw watermelon.

Ripe melon: Finger pat the watermelon, hear the "bang" sound and have an echo.

Preferably, the sound is dull and heavy is the ripe watermelon, we can also pick up the watermelon with our hands and put it in our ears, and squeeze it quietly with both hands, if we can hear the cracking sound in the melon, it is the ripe watermelon, and the raw melon is not cracking.

Gently tap the watermelon with your hands if you hear a very loud knock knock sound.

That's a good melon.

You can also touch the surface of the watermelon, if it is very hard and the skin is smooth, it is a good melon.

Look at the surface first, whether it is intact, then knock the watermelon and listen to the sound.

Look at the vines new and not fresh.

The dry instructions take too long.

Look at the lines on the watermelon.

If exposed to sunlight evenly.

The texture will also grow evenly.

Listening to the sound, it sounds relatively heavy.

Good melons have a crispy sound. Good elasticity. It is best to touch the broken melon vine again, and if it is freshly picked (the fracture is relatively new), it is the best.

1 Visual inspection. Look at the appearance of the fruit and the bristle tendrils. The surface of the fruit exhibits morphological characteristics such as skin color, reticulation or stripes inherent to the variety.

The ripe melon has clear veins, distinct shades, the base of the fruit stalk is slightly contracted, the navel is concave inward, and the landing part turns yellow; Under normal plant growth, the fruit setting node and the tendrils before and after are withered, and the bristles of the fruit stalk are sparse and fall off, indicating that the fruit is ripe.

2 Hand test. Flick the melon with your fingers or pat or touch the melon with the palm of your hand. The dullness of the melon is a ripe melon.

It produces a crisp and crisp sound for raw melon. When you touch the skin of the melon with your hands, the one that has a slippery feeling is the cooked melon, and the one that is astringent is the raw melon. One hand to hold the melon, one hand on the top of the melon gently patting, such as the palm of the melon slightly trembling, the melon makes a loud sound is a ripe melon, such as the hand of the melon does not feel trembling, the sound of the sound is raw melon.

Squeeze both ends of the fruit with both hands at the same time, put it in your ear and listen, if there is a hissing melon cracking sound, it is a ripe melon. For watermelons of the same variety and volume, raw melons are heavier than ripe melons, and overripe melons are lighter than ripe melons. Experienced people can use the identification method of "hand-held melon", that is, the second-hand melon is slightly lightweight, and the watermelon with good maturity is the watermelon.

3 Marking. After the female watermelon flowers open or pollinate, a 50 cm tall branch or bamboo strip is inserted next to the flower to mark it, and the upper end is painted with different colors. Change the color every 2 days and mark the single melon.

The ripening period is estimated according to the accumulated temperature or number of days required for each variety to mature. By marking the date of fruit set and checking the cutting of melons, the harvest is carried out at the right time according to the marking.

4 Specific gravity method. Fruit specific gravity was determined. The specific gravity of ripe watermelon and water is not the same at room temperature.

The density of watermelon with suitable maturity is that the proportion of raw melon is greater than and less than that of overripe melon. The watermelon can be put into the water for observation, if the watermelon is completely sunk, it indicates that the raw melon, the surface part is very large; Indicates that it is overripe and does not surface much, indicating ripe melon.

6 Instrumental assays. It can be used with a non-damaging melon and fruit tester produced in Shanghai. When measuring, as long as the center line of the probe of the tester is aimed at the center point of the fruit, it is less than or equal to 8 degrees for raw melon, and more than 8 degrees for cooked melon, and the accuracy is higher.

There is also a watermelon raw and ripening tester jointly developed by Shanxi Medical Device Factory and Pinglu County Native Fruit Company, with an operating efficiency of 380 melons per hour.

First of all, eat less or even no off-season vegetables and fruits, and out-of-season watermelon is of course not good.

Secondly, the general watermelon, knock it, if there is a crisp and ethereal echo inside, it is good, and the knocking feeling is more dull, it is a tender melon.
