1. The color of black wolfberry is very strong, like blue ink in tap water, purple in boiling water, and black after the concentration is particularly high.

2. After the black wolfberry is dry, it will become a powder if you pinch it by hand, because of the high sugar content, it has a meaty texture;

3. Black wolfberry can stand up with the fruit stalk facing up;

4. The water solubility of black wolfberry is particularly good, once it is splashed on the white cloth, it will come down after washing it with water;

5. After the black wolfberry is dried, the part where the fruit stalk is removed is a very round and white circle;

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.

1.See. One is to look at their seeds, the black wolfberry fruit has multiple small seeds in it, while the white thorn fruit has only one larger seed in it, and the seeds are small and many black wolfberry.

The second is to look at its shape, the black wolfberry is longitudinal that is, the axial short, the radial length is a transversely long oblate oval, while the white wolfberry is axial long, and the radial short oblong, flat is the black wolfberry.

The third is to look at its flesh, 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; The fake white thorn fruit is single-seeded inside, and it does not have the heavy blue-purple color of the black wolfberry.

2.Pinch. "Pinching" is the black wolfberry fruit that can be pinched by hand to become a powder, while Tangut white thorn fruit will not be easily crushed because of its high sugar content.

3.Taste. "Taste" is to put the fruit in the mouth to taste, Tangut white thorn fruit has a high sugar content and a sweeter taste, the sweetness of black wolfberry is not as high as Tangut white thorn fruit, and the sweetness is less black wolfberry.

4.Soak. "Soaking" refers to the dried black wolfberry soaked in water, with the release of anthocyanin, the color of the black wolfberry gradually fades, the soak time for a long time, the black wolfberry will become blue and white translucent, and there is a break open black wolfberry will find that there are about 10 small seeds in it.

It is particularly worth noting that the anthocyanins rich in black wolfberry are three times that of blueberries, anthocyanins are soaked in light blue using tap water, and the purified water is purple, but with the growth of soaking time, the difference will slowly decrease.

The color of the white thorn fruit is similar to that of the black wolfberry, and it is impossible to see it without looking closely. However, when you put the white thorn fruit in the water, the color of the bubble is lighter, and the blueberry is also soak in the water very quickly, the color is strong, and it will show different performances under different water quality, such as soaking acidic water (mineral water) into purple, soaking alkaline water (mountain spring water, tap water, etc.) into blue.
