How to distinguish the good from the bad of red dates, and how to distinguish the good from the bad

How to distinguish the advantages and disadvantages of jujubes 1, look at the color.

The color of high-quality jujube is generally purple-red, which will look darker, and the color is more uniform and shiny. The worse quality will be reddish, and the surface gloss is not good, and there will be a shallow and deep situation, which may also be caused by insects.

How to distinguish the advantages and disadvantages of jujube 2, look at the appearance.

The size of a good jujube is generally round, the shape is oval or spherical, the size is relatively uniform, and there are relatively shallow wrinkles on the surface but there is no damage. Some of them are relatively shriveled, some are very wrinkled, and some are damaged.

How to distinguish the advantages and disadvantages of jujube 3.

To distinguish between good and bad, you can also look at the cut surface of the jujube, the high-quality jujube is flat to cut, and the jujube core is relatively small, the fruit is relatively thick, and the tightness is relatively moderate. However, the almost red dates will be relatively dry and loose when cut, and the jujube pits are very large.

1.When picking jujubes, don't blindly pay attention to the size of the jujubes, but look at the fullness of the whole jujube--- when I first picked jujubes, I specially picked the big ones, and some of the results are tall on the outside, and the grass bales inside Those red jujubes that have softened, the vitamins contained in them have lost more than half, and they are not nutritious to eat. Freshness with few epidermal folds.

2. .Take a good look at the color of the jujube and the epidermis--- the skin color of high-quality jujube is purple-red, and the epidermis is smooth, without damage or cracking; The jujube color that is red after picking is slightly brownish.

Fresh jujubes are relatively plump, and those with fewer wrinkles on the skin are generally produced in the same year. Moreover, the skin of a good jujube is very shiny after scrubbing.

3.In addition to looking at the fullness, jujube skin and jujube meat, you can also taste it--- high-quality jujube tastes sweet and has a good taste, while inferior jujube will have a bit of bitterness and astringency when you bite into it. You can break the jujube to see that the jujube flesh inside --- inferior or softened jujube, after breaking the broken part of the jujube flesh is brown, and the intact jujube, the whole jujube flesh is a hue.

4.There is no moth with a stalk at the top. The sugar content of jujube is usually 60%-80%, and it is easy to be eaten by insects.

If there is no stalk at the top, you need to pay attention, if there are small holes, it is eaten by insects. You can also pinch it with your hands, and the flesh will feel soft and empty, or it may be moth-eaten.

The darker the color of the jujubes, the sweeter they are. Many people mistakenly think that the color of jujube is related to its freshness, and the darker the color, the older it is. But in fact, once the jujube is removed, the color of its skin changes very little.

By the color of the skin, we can judge the sweetness of the date. The darker the color, the higher the ripeness and the sweeter it is.

Method Steps:

Looking at the appearance, the color of high-quality jujube is purple red, the particles are large and uniform, there are few wrinkles, and the skin is thin and the core is small. If there are many wrinkles, the shape of the fruit is shriveled ,..

Look at the pedicle end of the jujube, if there is a perforation or brown powder, it means that the jujube has worms, and if you break it, you will see that there are insect feces at the core of the flesh.

Pinch the jujubes, if they feel smooth and glutinous and not loose, it means that the jujubes are fine and firm, and they are of the highest quality. If you pinch it by hand, it is soft and rough ,..

Grab a handful of jujubes with your hands, if it sticks to your hands, it means that the jujubes have been damp, should not be stored for a long time, and are easy to deteriorate.

One is to look at the fullness, gloss and color of the appearance. The second is to see if there are insects. The third is taste and sugar moisture.

The methods to identify good quality jujubes are:

1. Look at the color of the jujubes. The skin of a good jujube is purple and red, the color is a little deeper, similar to wine red, and it is relatively bright. The color of good jujube is uniform, and the uneven color may be caused by insects after a long storage time.

If there are perforations at the end of the pedicle of the jujube or there is brown or dark brown powder sticky, it means that it has been slowly eaten by insects.

2. Look at the shape of jujubes. The jujubes are large and uniform, short and round, with a round pedicle at the top and a shallow wrinkle on the surface. The quality of uniform and intact jujube varieties is relatively reliable.

3. The feel of jujubes. Holding the red dates in your hand, it feels firm, and the meat quality is fine***. The soft and rough feel indicates that the jujube is not dried thoroughly and the quality is poor. Wet and soft and sticky to the hand, it is very damp and cannot be stored for a long time.

4. Taste the taste of red dates. Cut open the red dates, the flesh is light yellow, fine, no silk is connected, and the quality of the entrance is sweet and glutinous. The meat is dark yellow, the core is large, there are filaments adherent, the taste is rough, the sweetness is insufficient or the quality is inferior with sour and astringent.

There are many ways to distinguish the quality of jujubes, which can be distinguished from the color of jujubes, the shape of jujubes, the feel of jujubes, and the taste of jujubes.

1. The color of the jujube.

The color of good jujube is relatively bright and uniform, shiny, and rarely appears a deep and shallow piece.

The color of the bad jujube is uneven, the surface gloss is not obvious, and the surface with a finch thickness also appears black.

2. The shape of the jujube.

Good jujube is large and uniform, short and strong shirt silver round, top round pedicle square, surface wrinkles are shallow, and the appearance is intact.

Bad jujubes are uneven in size, the surface water loss is more, the fruit is shriveled, and the wrinkles on the town are deeper, and sometimes there is breakage.

3. The feel of jujubes.

Good dates.

1. Look at the color.

Fresh dates, farmers generally pick and market when the dates are green. If the whole body of the date is relatively red, and the red is purple, it is best not to buy it. The sweetness of the jujube skin belt that has been soaked in saccharin, etc., will be a little bitter if you taste it carefully, and the sweetness will be significantly reduced after rinsing with water.

If the skin is sweet and the flesh is not sweet, be even more vigilant.

Although boiling water can promote red jujube, there is a certain difference between the effect of external forcing and the change of natural laws. Although it is difficult to distinguish from the color, there are many ways to identify ripe jujubes. First of all, look at whether the hardness of the jujube is consistent, the hardness of the jujube scalded in boiling water is often inconsistent due to the difference in the heating surface.

Second, look at whether there is a cavity in the jujube pulp to judge.

Jujube is scalded by boiling water, and under the influence of thermal expansion and cold contraction, some changes will occur inside the flesh, and there will be voids or cavities, while normal ripe jujube will not appear in this situation.

3. The fruit stalk of jujube is judged.

Under normal circumstances, on the fifteenth day of the seventh month of the lunar calendar, a red circle will appear at the fruit stalk of the jujube, and the nutritional content of the jujube at this time basically meets the requirements, but the appearance color has not turned red. If there is no red circle, such a jujube can be said to be completely unripe.

Fourth, lick the taste.

Before buying jujubes, you can lick the skin of the jujube, because the skin of the jujube soaked in "sweet water" is sweet. In addition, the ripened jujubes, due to the soaking, the shelf life is short, if the jujube bought home quickly rots, it is very likely that the ripening jujube was bought.

When buying winter dates, don't blindly pick a big one, but choose the one with a regular shape and a fragrant smell. There is also a secret to picking sweet winter dates: the body of the dates is mainly green, with about 1 3 red areas on it, and the sugar content of such dates is relatively high.

The one on the left is a bad date, and the one on the right is a good date.
