1. Look with your eyes.

To distinguish the authenticity of black goji berries, we can first look with our eyes. The shape of a true black goji berry is a flattened oval, which is short in axial direction and long in radial direction. And there are many small seeds in the fruit of black wolfberry, if you can't tell the truth of black wolfberry from the appearance, we can also pick up the black wolfberry to see if it is a small seed in the fruit, or only one big seed.

If there are many small seeds inside the black goji berry, it proves that it is a real black goji berry.

2. Soak in water for observation.

The most commonly used way to eat black wolfberry is to soak it in water and drink, which can also help distinguish its authenticity. After soaking in water, the water will slowly turn purple or blue-purple, and with the extension of soaking time, the black wolfberry will become blue and white translucent, and the color of the water will slowly deepen, and in the whole process, we can also clearly see that the brewing color of black wolfberry has the phenomenon of drawing blocks.

3. Use ** to identify.

Black wolfberry is a more precious resource, especially for those that grow in the wild, it is a treasure among the treasures, so it is relatively high, generally speaking, it is not surprising that a kilogram costs thousands of yuan. If there are some cheap black wolfberries on the market, you can buy a pound for dozens or hundreds of yuan, you need to be vigilant, it is definitely not a real black wolfberry, we should avoid being deceived.

Looking at their seeds, the black goji berry fruit has multiple small seeds inside, while the white thorn fruit has only one larger seed inside, and the small and many seeds are black goji berries.

2. Looking at its appearance, the black wolfberry is a longitudinal longitudinal that is, axial short, radial long, that is, a transversely long oblate oval, while the white wolfberry is axial long, and the radial short oblong oval, and the flat is black wolfberry.

1. Fresh black wolfberry, after the seeds are crushed, there are about ten small seeds in the authentic black wolfberry, and the shape of the small seeds is fruity; Inside the fake white thorn fruit is a single kernel. It is not as heavy blue-purple as the black wolfberry.

2. After the dried black wolfberry fruit is soaked in water, with the release of anthocyanin, the color of the black wolfberry gradually fades, and after soaking for a long time, the black wolfberry will become blue and white translucent, and the black wolfberry will be broken and found that there are about 10 small seeds inside;

Third, it is particularly worth noting that the anthocyanins rich in black wolfberry are three times that of blueberries, anthocyanins are soaked in tap water in light blue, and pure water is purple, but with the growth of soaking time, the difference will slowly decrease, and the black wolfberry is found to be the same color inside, and there is no way to do it, which is a good proof that black wolfberry is a natural color.
