Winter jujube generally ripens naturally in the solar calendar from 65438+ 10 to 165438+ 10. Because the weather in the north entered the cold earlier, it was named "Winter Jujube".

How to choose winter jujube

1, look at the color

When choosing winter jujube, we must pay attention to its surface color. If the winter dates are all red, don't buy them, because they are completely ripe and easily broken. We should choose semi-red or a little red winter jujube, which is the best maturity.

Step 2 look at the hardness

When choosing winter jujube, you must look at its hardness. It can be said that the harder the winter jujube, the better. If the winter jujube is soft, it must be air-dried. In any case, you must choose a winter jujube with more cyan, and a harder winter jujube is the best.

Step 3 look at the shape

When we buy winter dates, we must try to choose round winter dates, long winter dates and oval winter dates. Round winter jujube, its core will be smaller and its taste will be better.

Step 4 taste it

From the taste point of view, we should choose crisp, sweet but not greasy winter dates in our mouth. Authentic winter jujube looks like a small apple, which tastes sweet but not greasy and has little residue.

Step 5 look at your head

When buying winter jujube, you must choose a winter jujube with a relatively uniform head, so that the stone of winter jujube will be smaller and taste better.

How to identify saccharin winter jujube

The so-called "saccharin winter jujube" means that criminals soak low-grade inferior winter jujube with saccharin water to increase sweetness, improve color and improve social status. China's National Food Safety Standard (GB 2760-20 14) stipulates that saccharin can be used in a variety of foods within a limited range, such as pickles and jam, but it is not allowed to be used in fresh fruits. So how to identify saccharin winter jujube?

1, look at the color

Natural mature winter jujube gradually changes from cyan to red, so it is mostly green and crimson, and there is no obvious dividing line between green and red; However, the winter jujube soaked with saccharin is mostly dark red or dark yellow, which is obviously different from the cyan part.

Step 2 touch the texture

The skin of naturally mature winter jujube is smooth and hard, and the skin is closely attached to the pulp; However, the pericarp of saccharin jujube is sticky, even wrinkled, with loose epidermis and soft pedicel.

Step 3 taste it

Naturally ripe winter jujube is crisp and refreshing, with the sweetest flesh, tasteless peel and natural fragrance; Saccharin jujube is soaked, the peel is sweeter than the pulp, the aftertaste is slightly bitter, and the washed water is also sweet.
