Do you really know goji berries, maybe all you know are wrong

goji berries is worng

Let me ask everyone a question first: Why do you eat wolfberry? Many friends will say “for nourishment and health care”, so do you know goji berries, do you know goji berries, what kind of goji berries are good, and what are the main problems with goji berries? Let’s take everyone one by one to unveil the veil of wolfberry.

Everyone will definitely say that wolfberry is of course the best in Zhongning, Ningxia. Some people say that it is big, sweet, delicious, beautiful, looks pleasing to the eye, clean, and good.

People who have a little knowledge of goji berries also know that not all goji berries are from Ningxia, and most of them are from other places, and many of them are treated with sulfur. Many people also know that soaking in water to see the ups and downs, look at the color, look at the goji berries To judge the origin of the fruit stem marks, in fact, what you know about wolfberry is used to judge the wolfberry, that is really cheating yourself.

goji berries is worng

Take 10 kinds of wolfberry for you to use which methods to identify, you will definitely mess up your hands and feet, and you think everything is right. In fact, Ningxia wolfberry is famous because of its high medicinal value and high trace elements. Regardless of the place of origin, the current problem of wolfberry is two major problems, pesticide residues and sulfur.

The phenomenon of wolfberry sulphur fumigation is very common, and there are many related reports in the media every year. Many people think of smelling, looking at the color, and tasting the smell when mentioning sulfur smoke. These identification methods have long been outdated.

The technology of sulphur smoking is also advancing with the times. A trace of sulphur smoking or the addition of a trace of sodium metabisulfite looks similar to normal wolfberry and tastes the same, which is difficult to identify with our naked eyes and tongue.

It is because it is not easy to identify. Xun M Xun can only be the seller’s final say, so many sellers just go to the wolfberry field to take some photos and fabricate some inexplicable concepts under the banner of self-produced and self-sold and entrepreneurial. Anyway, it is impossible to go. Verify his authenticity!

There are two forms of sulfur fumigation, one is to burn sulfur directly for fumigation, and the other is to add sodium metabisulfite. Both of these methods improve the quality of wolfberry through the vulcanization reaction, so as to reduce costs and reduce losses.

Rumor one, the one that fades in water is dyed, and the one that does not fade is natural.

After receiving the wolfberry, a buyer asked: “I just received your wolfberry and grabbed a handful to wash it. I found that the water is so yellow and the hands are stained. What’s the matter? Is your wolfberry? Dyed!” I said this is normal, but buyers are always worried.

This kind of thought is taken for granted by imagination, spread the most, and the most harmful. In fact, if there is no color in the water, it is easier to buy wolfberries that have been fumigated with sulfur. So I will use the largest space to explain to everyone the most tangled dyeing problem.

  1. What is the true color of wolfberry?

Lycium barbarum itself contains natural pigments such as carotene and riboflavin. These pigments dissolve in water and will be orange-yellow when exposed to water. Soaking wolfberry in cold water is darker than boiling water. The natural pigment in wolfberry is unstable, and hot water has a destructive effect, so the color will be light instead. Of course we use hot water for soaking. You can experiment.

  1. There are feedbacks from customers that the hand is yellow when it is touched by the hand, and why is it still touching?

Goji berries need to be dried to keep them well and not easy to deteriorate. Our wolfberry is relatively dry. During drying, handling, bagging, transportation, etc., part of the fruit pulp will be rubbed off due to the mutual friction of wolfberry, producing wolfberry pulp powder. The fine wolfberry pulp contains natural pigments and will be yellow to the touch, and contains a lot of fructose. Dip your hands. This discoloration is due to natural pigments such as carrots and riboflavin in the wolfberry itself. It was not infected.

  1. How is wolfberry dyed?

I have been dealing with goji berries for so many years, and I have seen all goji berries, and I have never seen the use of pigments to color goji berries. I don’t believe that after you soak the medlar to soften it, then rub the medlar, you will find that the pulp of the medlar is orange, and it has natural coloring, so there is no need to add additional coloring.

The color of wolfberry will turn red and bright because it is fumigated by sulfur or mixed with sodium in the sun. This phenomenon, which people call dyeing, is actually bleaching chemically, not adding pigments. The “dyed” wolfberry has a pungent sulfur smell.

No color is precipitated in the water. After sulfur treatment, wolfberry has stable properties, does not change color and does not grow insects. But eating things smoked with sulfur damages the liver and kidney function, which is not superficial.

What people usually call “dyeing” wolfberry is actually just an image of saying, not to add paint. It is not accurate at all to judge whether the wolfberry is dyed by soaking the wolfberry in water. Even go astray.

Rumor two, only Ningxia Zhongning wolfberry has white tips

In fact, this is not mysterious at all. Lycium is a plant of the Solanaceae family and eggplant, tomatoes, and peppers are all relatives. The so-called white tip of Lycium barbarum is the stalk mark on the contact part between the fruit of Lycium barbarum and the stalk. There are stalk marks on the stalk of Lycium barbarum in all places.

Lycium berries need to go through drying, storage, handling, bagging, transportation and many other steps to reach your hands. The dried medlars are very dry, and it is easy to break the medlars and remove the white spots.

The stalk marks on eggplants, peppers, and tomatoes can be seen after removing the stalk. I haven’t seen any people using this thing in the vegetable market. This is by no means a unique selling point.

Using this method is not reliable at all, it is easy to misjudgment, and the false injury error rate is 90%. Sometimes it’s really anxious for the “brick family”!

Rumor three, the wolfberry floats after soaking in water is Ningxia, and most of the sinking is out of town

Floating and sinking are highly correlated with the density of wolfberry. When the wolfberry is just dried, the gaps between the wolfberry are relatively large, the density is small, and it is easy to float. After the wolfberry is put into storage, the lower layer of wolfberry is squeezed, the gap between the wolfberry is small, the density is high, and it is easy to sink. Even Qinghai wolfberry and Zhongning wolfberry have floating and sinking phenomena.

This method is widely spread, and many shops use it to judge. They are sloppy. Qinghai wolfberry photos can not be bought wrongly, and people who do not understand the inside story are fooled.

Rumor 4, the wolfberries from Ningxia are all authentic Ningxia Zhongning wolfberries

When a customer told me that he had been to Ningxia, the wolfberry bought in Ningxia was big and sweet and the quality was very good. I had a headache and I didn’t know what to say. It’s not that my things can’t stand the test, but a surprising fact is that nine out of ten goji berries sold in specialty shops on the streets of Ningxia are not Ningxia Zhongning goji berries. Most of them are faked with Qinghai goji berries. . What Ningxia buys is not necessarily Ningxia Zhongning wolfberry.

Ningxia Zhongning’s unique geographical environment and hydrothermal conditions have created Ningxia Zhongning wolfberry. Zhongning wolfberry has a long history and good quality, and was listed as a tribute in the Ming Dynasty.

His medicinal value is recognized in the medical field, and it is the only medicinal wolfberry listed in the “Pharmacopeia of the People’s Republic of China”. Zhongning wolfberry is the best quality wolfberry, under the reputation, many frauds.

Although wolfberry is small, it has a lot of knowledge. I do not have more than 5 years of experience in making wolfberry, and basically I have not touched the threshold.

Looking at wolfberry is a very professional thing, but buying wolfberry is an unprofessional customer.

You look at the same wolfberry, but in fact, the inner quality is very different. Lycium barbarum has connotations like tea. Qinghai wolfberry of the same size is half the price of Zhongning wolfberry. With huge profits, it is difficult for ordinary businesses to have such control. On the other hand, ordinary customers generally don’t have this distinguishing ability. Just looking at the price and looking at it will mess up the market. In the end, the evolution of the market can only be that bad money drives out good money and forces merchants to counterfeit. I traveled all the way to Ningxia and spent the wrong money. The things I bought were not authentic and had no medicinal value.

Rumor five, Ningxia Zhongning wolfberry is big, thin, thick, sweet?

Li Shizhen’s description of the Chinese wolfberry used as medicine is as follows: “Compendium of Materia Medica” Mube wolfberry [Xiuzhi] Shizhen said: Everyone who picks up the stems and picks the bright ones will be washed, and the wine will be moisturized with bitterness and coldness. : Gan, Ping. “

Ningxia Zhongning wolfberry is a medicinal and health-care wolfberry. If it is small, you can chew and taste it carefully. The sweet and slightly bitter taste. This kind of bitterness is found on the tree, and the natural bitterness can be tasted by people with a keen sense of taste. Look at the smell of Chinese wolfberry.

Ningxia Zhongning wolfberry is generally small and 220 is considered large. On the market, Qinghai wolfberry is used to pretend to be Ningxia Zhongning wolfberry. Thin skin and thick flesh, less seeds and sweet taste. This is precisely the characteristic of Qinghai wolfberry.

Will wolfberry add sugar?

I once saw an expert on TV saying that the wolfberry is soaked in syrup when it is touched by hand. It is not that the wolfberry is soaked in the hand, but that the wolfberry is not sweetened, whether it is good or bad. Because wolfberry itself contains a large amount of fructose, this is the phenomenon of fructose in wolfberry absorbing moisture in the air.

Wolfberry is afraid of high temperature and humidity. After you receive the goods, please store the wolfberry in a cool and dry place. Opened goji berries should be sealed and stored in a cool and dry place if you can’t finish them. Or keep it in the refrigerator at 0-4℃ after sealing.
