Abstract: how to distinguish dates made from sulfur fumigation? It only takes three steps to "one look, two peel and three taste".

At present, Xinzheng jujube and Shanxi jujube have been picked, and the jujube in southern Xinjiang has also entered the harvest period. Jujube in this season is really a timely thing. Since ancient times, red jujube has been indispensable in the recipes of pregnant women and pregnant women. It can be seen that the effect of raising people is not small, and sun-dried jujube as a snack is also a very good choice, so how to distinguish between jujube smoked by sulfur at ordinary times? How to choose when buying red dates?

Why do some black-hearted traders carry out sulfur fumigation?

After the jujube is ripe, the jujube farmers, after picking, divide the jujube into three or six or nine grades of different quality. generally, the jujube with large size and full fruit is divided into one category, and the smaller jujube is divided into two or three categories with bad appearance. The wormeaten, moldy or rotten pericarp belongs to scrap products. Red jujube vendors buy them according to the first category, second category and third category. After returning to the factory, they go through detailed picking and picking. After packaging, the low-grade jujube is listed on the market, and the low-grade jujube is small, especially the jujube in southern Xinjiang is naturally air-dried after the wind and the sun. The folds of these dates are full of sand and do not slip away in autumn. In order to make these dates have a good sales appearance, vendors carry out sulfur treatment on low-grade jujubes. The sulfur-treated dates are smooth in appearance, just like waxing, and they look like they want to take a bite. Such dates naturally look much better and are naturally welcomed by the market.

The harm of jujube smoked by sulfur.

The jujube smoked by sulfur not only destroys the nutrients of the jujube itself, but also destroys the vitamins and calcium inside the jujube. Moreover, there are some residues of hydrogen sulfide, lead and arsenic, which are harmful to the human body, which have a great stimulating effect on the intestines and stomach of the human body. if there are more residues, they may even cause central nervous system symptoms such as headache, fatigue and vomiting, and the residual heavy metals will also cause damage to the kidneys and liver to a certain extent. Generally speaking, jujube smoked with sulfur does a lot of harm.

How to tell the difference between sulfur-smoked dates. On the whole, it can be divided into "one look, two peels and three tastes".

A look, mainly depends on the appearance and color. The jujube whose appearance is smooth and waxed is definitely not a normal mature jujube. The normal jujube has many wrinkles in color, just like the wrinkles after wind and sun. In addition, it depends on the color, because sulfur has a bleaching effect, if the jujube is red and bright, it is smoked, and the dark red and uneven color is the normal jujube.

Second peeling, as the name implies, that is, after peeling, the color of the normal jujube gradually deepens from the outer skin to the core, from light yellow to dark yellow, and those close to the core are even as dark as the core. This is the good fruit that is normally ripe. The fruit smoked by sulfur naturally has the color of bleached fruit, which looks white.

Three tasting, only practice can be true knowledge, if the taste does not slip autumn, fumigation fruit is no doubt. If the taste is sweet, as soft and waxy as a cake, the flesh is strong, and the tooth surface can even feel sweet water and aroma, there is no doubt that this kind of fruit is real.

How to distinguish a good jujube when buying dates.

Authentic Xinjiang jujube is roughly divided into two categories: grey jujube and Junzao. Gray jujube is small, the flesh is firm, and the taste is good. Junzao is big, and the jujube before air-drying is as big as an egg, and the first kind of jujube after air-drying is not much smaller than the egg. Because Xinjiang is windy and sandy, the fruit is naturally air-dried on the trees, it is like pulling it out of the soil after picking, and most of the Xinjiang dates are acquired by the local Xinjiang Corps, so it is not easy to eat real Xinjiang dates. The brighter the jujube is, the more you want to avoid it, and choose the gray jujube. After breaking up, the flesh is shredded, the color is light and deep inside, the pulp is firm and tough, and the taste is delicate and sweet. This kind of jujube is the real first-class jujube.
