You may not believe it, but Dongzao is a well-deserved "vitamin C tonic pill"

Autumn is the season of fruit harvest, and a large number of fruits are listed in turn. From 10, you can see Dongzao in both fruit shops and fruit stalls. Winter jujube is thin, crisp, sweet and fragrant, and many people like it.

Although winter jujube is small, it has many advantages, and eating winter jujube is also a bit particular. Next, Xiao Er will tell you in detail.

First, you may not believe that the vitamin C content of winter jujube is so high!

Speaking of the nutritional value of winter jujube, there is a name that can be said to be "vitamin C tonic pill".

Although the figure is short, small and round, the content of vitamin C in the round body of winter jujube is as high as 243 mg/ 100 g, almost 60 times that of apple, 0/0 times that of lemon and 4 times that of kiwifruit. It can be called "the king of vitamin C in fruits".

The above data are only average values, and the highest vitamin C content of some varieties of Dongzao dates can even reach 500 ~ 600 mg/ 100 g.

When you meet such a good jujube, you only need to eat one or two, and you don't have to worry about the vitamin C that the human body needs in one day (the recommended intake of vitamin C is 100mg/ day).

In addition to vitamin C, the contents of dietary fiber, folic acid and nicotinic acid in winter jujube are also outstanding among fruits.

However, these are fresh winter dates, and the nutrition (especially vitamin C) of stale winter dates will be greatly reduced.

Grade of VC content per100g of food (mg)

(Data are quoted from China Food Composition Table 20 18 Standard Edition).

Powerful vitamin c

Vitamin C is very important for the formation and manufacture of strong immune system, bones and collagen, and it is also a powerful antioxidant.

Vitamin C plays an important role in fighting various cancers and cardiovascular diseases, as well as the common cold and oral ulcers.

It can be seen that vitamin C plays an important role in preventing gingival atrophy and bleeding, preventing arteriosclerosis, inhibiting the harm of free radicals to human body and improving human immunity.

Second, winter jujube is very sweet. Is it made with saccharin?

Every year when winter jujube is listed, there will be an old rumor in the circle of friends:

Many people will worry: winter jujube is so sweet that it won't be soaked with saccharin or sodium cyclamate, will it?

In fact, due to the natural advantages of varieties, the sugar content of winter jujube can reach 25% ~ 38% after maturity, and there is no need to add sweeteners to "sweeten". Therefore, most of the very sweet winter dates are fine, so you can buy them with confidence.

However, there are indeed some unscrupulous traders in the market who will hand-make some red-skinned winter dates in order to make black-hearted money in advance. The most common method is to soak raw dates in hot water bath with saccharin sodium or sodium cyclamate.

Sweetened with sweetener and ripened in hot water bath, the original green jujube peel will turn red and absorb a certain amount of saccharin or sodium cyclamate. At first glance, it looks a bit like a ripe winter jujube.

But it's not true. It's fake. There are obvious differences between naturally matured dates and dates soaked in hot water. There are two ways to distinguish them:

1. Look at the color.

Naturally mature winter jujube: the red color is uneven and scattered in dots, and the slightly yellow part that is not red indicates higher sweetness;

Boiled winter jujube: the distribution of red is unusually uniform and tidy, generally red or the boundary between green and red is obvious.

Taste it

Mature winter jujube: the flesh is crisp and the sweetness is even and natural;

Soaked jujube in winter: usually only the skin is sweet, even bitter, while the jujube meat is dry, firewood and sour.

Saccharin sodium or sodium cyclamate is a legal food additive, and it is no problem to add it to food in moderation, but it cannot be used for fresh fruits.

3. What is the relationship between winter jujube and red jujube?

I believe many people will want to ask when they see the red winter jujube:

Can it be eaten as red dates after drying?

In fact, simply speaking, jujube is a general term for a large class of "Rhamnaceae Jujube" plants. There are many varieties, but there are three common ways to eat them: making candied dates, eating them fresh and drying them in the sun.

Jujube is a kind of dried jujube, and there is no strict variety restriction. All kinds of ripe fresh dates are made into "dried dates" after drying in the sun to remove water, which belongs to the category of jujube. The most common red dates on the market are mainly individual varieties such as Huizao, Junzao and Jinsixiaozao.

Winter jujube, a variety with thin skin and crisp meat, can also sell at a high price. Of course, fresh food can give full play to its advantages, and few people are willing to use it to make red dates.

If you have to dry wet winter jujube to make "red dates", it is not impossible, as long as you ensure that it does not rot and mildew in the process, but don't expect such "dried winter jujube" to supplement VC.

Fourth, although winter dates are good, you can't eat more at once!

As a sweet fruit, many people can't keep their mouths shut in front of winter dates. Eating one pot at a time is definitely not a case.

The sugar content of winter jujube is 25% ~ 38%. This unusual sugar content not only shows that it is delicious, but also means that the calories in it can never be ignored.

Generally speaking, the heat of winter jujube can reach 105 kcal/100g, which is similar to that of rice (1 16 kcal/100g).

What is the concept of 100 g winter jujube?

There are only about six or seven medium-sized ones.

Excluding the stone, the meat of 108 g winter jujube is almost100 g.

If you are slumped on the sofa, you are going to wipe out a pot of winter dates while brushing your mobile phone. ...

You can pinch the autumn fat that has just been pasted on your stomach these days, and think twice before you act.
