A small amount of saccharin jujube is consumed by humans, and there is no obvious harmful effect. However, when people consume too much saccharin sodium, it will affect the normal secretion of gastrointestinal digestive enzymes, reduce the absorption capacity of the small intestine, and reduce appetite. Moreover, the cells of saccharin jujube are destroyed after soaking, and they are easy to be contaminated by bacteria, and people may have diarrhea symptoms if they eat too much.

3. The soaked saccharin jujube has a loose skin with wrinkles and a soft feel. In some cases, the peel will be separated from the pulp.

5. How to buy jujubes

1. Look at the size of the jujubes.

First of all, look at the size of the dates. The small jujube is dark red in skin color, and the large jujube is purple and red in skin color, and the new goods have a natural luster, and the old goods have a thin frost is better.

Second, look at the shape of jujubes.

Look at the radian, it is oval or spherical. If there are too many folds, you should pay attention to the humidity of the jujube is too dry, but if it is too smooth, you should also pay attention to it, and you should not pay attention to the time because the moisture is relatively sufficient, and it is not easy to keep. If you have a jujube scar, don't think that the jujube is broken, it is a very normal phenomenon.

In addition, some jujubes may be uneven in color, don't worry, practice has proved that the more sugar content of jujubes, the darker the color of jujube flesh. Pay special attention to whether there is a perforation or brown powder sticking to the end of the pedicle, if there is, it indicates that the flesh has been eaten by insects, and a circle of insect chips can be seen between the kernels after being broken.

3. Look at the hardness of jujubes.

Again, pinch the jujube tightly with your hand, if you feel smooth and glutinous and not loose, it means that the quality is fine and firm, the jujube body is dry, and the core is small; If the sweetness is poor, there is a sour and astringent taste, pinch it by hand, it is soft and rough, the quality is poor, if it is wet and soft and sticky, it means that the jujube body is more damp, not durable to store, and easy to rot and deteriorate.

Fourth, look at the inside of jujubes.

Finally, break open the red dates, the flesh is light yellow, fine, no silk is connected, and the entrance is sweet and glutinous; The flesh is dark yellow, with large cores, connected by strands, and has a rough taste, with insufficient sweetness or poor quality with a sour and astringent taste. If it is a smoked red date, the surface is bright red and relatively fat.

Fifth, look at the types of jujubes.

According to the size, it can be divided into large jujube and small jujube.

According to the production area, it is divided into southern jujube and northern jujube.

According to dry and wet, it is divided into fresh food and dry food.

The scientific name of saccharin jujube is winter jujube, which is a winter jujube after abusing the addition of saccharin sodium and cyclamate additives to turn fresh jujube red and sweetened.

These dates are likely to be soaked in water with sour and astringent green dates with sodium saccharin to become red and sweet, and even called"Eating a large amount of saccharin sodium in a short period of time will cause acute hemorrhage, which will have adverse effects on the liver and kidneys, and can cause cancer in serious cases.

How to tell: Look at the color. Naturally ripened jujubes are generally from green to yellow and then to red, and the core oak is a process of gradual ripening and discoloration, and there is an uneven natural color on the peel, which will not be green and red.

If it is a jujube soaked in saccharin sodium, it is generally half red and half green, and the boundary is particularly clear;

Two tastes of the peel. The skin of the naturally ripe jujube is not sweet, but the flesh is sweet. The skin of jujube soaked in saccharin sodium is sweeter than the pulp;

Third, look at the roots of jujubes. Generally, the roots of jujubes soaked in saccharin sodium are wilted.

It is best not to eat saccharin-soaked jujubes, because sodium saccharin is an organic chemical synthetic product and a food additive, in addition to causing a sweet feeling in taste, it does not participate in internal metabolism, does not produce calories, has no nutritional value, and is discharged with urine, and has no nutritional value for the human body. When the amount of saccharin sodium is large, it will affect the normal secretion of gastrointestinal digestive enzymes, reduce the absorption capacity of the small intestine, and reduce appetite. Eating a large amount of saccharin sodium in a short period of time will cause acute hemorrhage, which will have adverse effects on the liver and kidneys, and can cause cancer in severe cases.

The first step in identification: look.

From the outside, the naturally ripe jujube, the jujube skin shows an uneven color of green, yellow and red lights, and it will never be separated from red and green.

Jujubes soaked in sugar water are dark red in color and red and green.

Step 2: Touch.

After a few days, the surface of the skin of a normal jujube will be wrinkled, but the flesh will not rot, and it will feel very dry when bitten.

Jujubes soaked in sugar water will rot after 1-2 days because the cells have been destroyed.

Step 3: Taste.

Naturally ripened dates become sweeter the more you chew, and the skin has a faint astringency.

The soaked jujube peel is sweeter than the pulp, and there is a faint bitterness in the aftertaste.

When you pick dates, you must not pick the ones that are too red. Abide by the three principles of picking bezoars above, and you can stay away from saccharin bezoars.
