1. All black wolfberry true and false identification methods.

1. Distinguish the real from the fake.

Black wolfberry is a thorny shrub, multi-branched, with hard branches, purple-black berries, globous, sometimes slightly concave at the apex, 4-9 mm in diameter. More than 95% of black wolfberries are stalked, and the fruit contains 5-8 seeds, which become powder when pinched by hand after drying. The white thorn fruit is dark red in color, there is no fruit stalk, the fruit is ripe and the stalk falls off automatically, it is single-cored, and it is very hard to pinch by hand.

Blueberry fruit is purple-black, stalkless, seedless.

Furthermore, observing the fruit stalk, the fruit pedicle of Qinghai black wolfberry is gray-white, and if a large number of fruit stalks are blue, it must be dyed.

2. Distinguish the real from the brewing color.

The color of black wolfberry soaking water is very strong, soaking in tap water (acidic water quality) is blue, and in mineral water (alkaline water quality) is purple; The sugar content is low and the water is slightly sweet. The white thorn fruit soaking water is very light in color, has a high sugar content, and has a sweet taste. Blueberries are lighter in color, have higher sugar content, and have a sweeter taste after soaking in water.

Authentic black goji berries are put into tap water, and the blue color appears like silk threads. As soon as the dyed fruit is put in water, a large blue color appears. In case of dyed black wolfberry, there is generally only one color for brewing, and it will not have different colors under different conditions.

3. Distinguish the advantages and disadvantages from the place of origin.

The best wild black wolfberry is produced in Qinghai, because the anthocyanin content in the black wolfberry produced in Qinghai reaches more than four points, which is higher than the black wolfberry in Xinjiang, Gansu and other places. The real black wolfberry, especially grown in the wild, has precious resources and limited output, at least about 2,000 yuan per catty.

And other counterfeit black wolfberry fruits, a pound is often no more than 100 yuan. If you encounter a black wolfberry that is too cheap, you should be vigilant, it may be a counterfeit.
