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 jujube is all red, we should not buy it, because the winter jujube is completely mature and easily broken. We should choose winter jujube with half red or a little red, which is the best maturity.
2. Look at the hardness
When choosing a winter jujube, we must look at its hardness. It can be said that the harder the winter jujube is, the better. If the winter jujube is soft, it must be air-dried. In any case, we must choose a winter jujube with more cyan, and a harder winter jujube is the best.
3. Look at the shape
When we buy winter dates, we must choose round winter dates, long winter dates and oval winter dates as far as possible. Round winter jujube, its core will be smaller and its taste will be better.
4. Taste the taste
In terms of taste, we should choose the crisp ones and put them in our mouths to chew the sweet but not greasy winter dates. Authentic winter jujube looks like a small apple, tastes sweet but not greasy, and has less residue.
5. Look at the 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" refers to the illegal personnel soaking low-grade and poor-quality winter jujube in saccharin water to increase sweetness, improve color and raise social status. China's "National Standard for Food Safety" (GB 2760-20 14) stipulates that saccharin can be used in a limited range for a variety of foods, such as pickled vegetables 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
Naturally mature winter jujube gradually changes from cyan to red, so it is mostly green and deeply red, and there is no obvious dividing line between green and red; However, the winter jujube soaked in saccharin is mostly dark red or dark yellow, which is obviously different from the cyan part.
2. Touch the texture
The skin of naturally mature winter jujube is smooth and hard, and the peel and pulp are closely attached; However, the skin of saccharin jujube is sticky, even wrinkled, the skin is loose and the fruit pedicle is soft.
3. Taste it
Naturally ripe winter jujube is crisp and refreshing, with the sweetest flesh, tasteless peel and natural fragrance; Because of soaking, the peel of saccharin jujube is sweeter than the pulp, and the aftertaste is slightly bitter, and the washed water is also sweet.
