What are the identification methods of "Pangma" wild black Lycium barbarum? Where is the best?

Black wolfberry is a popular health-preserving product in recent years, which contains high levels of anthocyanins. Among them, the price of wild black Chinese wolfberry has soared, and many online sellers say they sell wild black Chinese wolfberry, and consumers are gullible and do not even understand the difference between wild black Chinese wolfberry and artificially cultivated black Chinese wolfberry. Today I will teach you some ways to identify wild black wolfberry and artificial black Chinese wolfberry.

First, the size of wild black wolfberry

Some businesses speculate on the size of black wolfberry and advertise it as "the best black wolfberry" at a high price. In fact, the environmental conditions for the growth of wild black wolfberry are extremely difficult, generally relatively small, in which there are indeed a small number of large fruits, but they can only be obtained by careful selection, and the number is very limited; most of the big black wolfberry are cultivated artificially, because artificial cultivation generally uses chemical fertilizers and pesticides, black wolfberry plants grow very strong, and the fruit is naturally larger than that in the wild.

2. Maturity of wild Lycium barbarum L.

Wild black wolfberry grows on wild beaches, and locals scramble to pick in order to sell money. often only some of the fruits are picked when they are ripe, and ripe fruits are picked together, so the maturity is inconsistent. Of course, more fruit affects the quality, and the anthocyanin content of fruit is low.

Third, the appearance of wild black wolfberry

The appearance of wild black Chinese wolfberry is often worse than that of artificial cultivation, and it is easy to bring a small amount of fine sand and other impurities when growing and picking in the field; wild black Chinese wolfberry is often destructively picked, cut off together with branches and dried for fruit, and a small amount of fruit may be broken, seriously affecting the appearance of the fruit. Artificially cultivated black wolfberry has meticulous management and clean fruit, and the grower is reluctant to prune and damage less fruit in order to ensure next year's yield. ?

Fourth, the cultivation and planting area of wild black wolfberry

Black wolfberry is distributed in the arid desert areas of the five northwestern provinces, and the output of Xinjiang, Gansu and Inner Mongolia is even more than that of Qinghai. Qinghai is the first place to develop and utilize black Chinese wolfberry. After long-term field collection, there are fewer and fewer wild resources, and now it has developed black Chinese wolfberry cultivated on a considerable scale, while the development of black Chinese wolfberry in other northwestern provinces is relatively late. wild resources are still rich, artificial cultivation is also relatively few. In other words, a considerable amount of Qinghai black wolfberry has been artificially cultivated, black wolfberry from other provinces is more likely to be wild.

Without exception, the goods of southern merchants are said to be made from Golmud in Qinghai, but in fact, some of their goods are purchased from Gansu, Xinjiang or other places. Even if there are many businessmen in Qinghai who buy large quantities of black wolfberry from Gansu, Xinjiang and other places every year, their goods may not be produced in Qinghai. Qinghai black Chinese wolfberry has been well-respected and well-known, while black Chinese wolfberry from other places (mainly Gansu and Xinjiang) is not well-known and is often sold by illegal traders and profiteers. In fact, there are quite a lot of desert saline-alkali land in Gansu and Xinjiang, and the yield of black wolfberry is also very large, and its quality is about the same as that of Qinghai black wolfberry (both in appearance and anthocyanin content are very similar to Qinghai black wolfberry).

Price of wild black wolfberry

Those who sell black wolfberry at high prices online are mostly businessmen from the south (Guangdong, Shanghai, Shenzhen, Zhejiang, etc.) and Qinghai, whose prices are much higher than those of origin. And some merchants who sell at normal prices often attract attacks from "fake goods" and "inferior goods".

In fact, the quality difference between the black wolfberry sold at high prices and the black wolfberry sold at normal prices is very small, and the biggest difference between the two is profit. As for the white thorn fruit pretending to be black wolfberry sales are now very few, because they are still very different. Nitraria is the drupe of Tribulus terrestris and Lycium barbarum is the berry of Solanaceae. They are as different as peaches and tomatoes. Especially the merchants of origin, their supply is abundant and the purchase price is relatively low, so there is no need to cheat at all.

VI. The difference between wild black Chinese wolfberry and planting black Chinese wolfberry

Wild black Chinese wolfberry is better than artificial black Chinese wolfberry, in fact, because of its high anthocyanin content, excellent speed, excellent and more lasting, and there is no fertilization, no medicine. Knowing this, it is easy to identify wild or artificial.

7. Identification method of wild black wolfberry

1. Anthocyanin content:

That is, the same weight of black wolfberry, soaked in the same volume of water (water temperature, PH, soaking time is the same), the darker the color, the more anthocyanin content, the higher the anthocyanin content, the better.

2. Whether it grows naturally in the wild:

Wild growth conditions will not be very superior, the general fruit will not be very large, the local people scramble to pick, the fruit maturity is not very consistent, inevitably mixed with individual immature fruit; field growth, often with trace impurities. On the other hand, the growth conditions of artificial cultivation are superior, the seedlings and fruits are strong, the picking time is easy to control, the fruit maturity is the same, and the fruit surface of protected cultivation is very clean.

In other words, the color is dark black, the color is fast in the water, the wire drawing phenomenon is obvious, and the anthocyanin is dispersed in the cup in the form of smoke. Natural wild and manual picking are the four main criteria for judging authentic wild black wolfberry. The essence of fruit with a small amount of fine sand is an important symbol of wild picking in the desert.

3. Moisture content of black wolfberry:

Normally picked black wolfberry, if naturally cool in the sun, air-dried, the moisture content is almost zero. When a complete black wolfberry is rubbed with the hand, the whole grain fragment can be seen, but there is no color on the hand. It is not the so-called "big and black" Chinese wolfberry recommended by some buyers, which has a high moisture content, just like red Chinese wolfberry, which is sticky in the hand, and even many black Chinese wolfberry stick together. This kind of Chinese wolfberry with high moisture content infringes upon the interests of consumers, and it is extremely prone to mildew and deterioration. In addition, the picking method also directly affects the shape, stalk length and particle integrity of black wolfberry, thus affecting the grade.
