How to distinguish the authenticity of black beans

It is found that many people have eaten black beans in their lives, and they all know that black beans are very effective, but no one thought that black beans can be faked, because some black beans are yellow in the middle, and some black beans are green in the middle. So everyone needs to know how to distinguish the authenticity of black beans to avoid buying fake or inferior black beans when buying black beans.

1. There are two kinds of black beans. If you distinguish them by the kernel of the black bean, one kind has yellow kernel; the other kind is green kernel black bean, which can grow green bean sprouts and is generally used as a medicinal material. Previously I thought that only green kernels were true black beans, but that was actually wrong. Black beans also have yellow kernels. Some people also say that there are white kernels, but I haven’t bought any yet, so I won’t discuss this for now.

2. Black beans can be divided into medicinal and edible types. Medicinal black beans have a green core, while edible black beans have a yellow core.

3. To identify black beans, first look at the bean skin. When you peel off the skin of real black beans, the inside is white. Because the bean skin is very thin, the color of the dyed black beans will penetrate the inner skin. After peeling off the black skin, you can see that the inside of the black skin will also change color. The real black beans have shiny skin. If it is blurred due to transportation, it can be shiny by rubbing it with your hands. However, fake black beans have no luster no matter how you rub them.

4. The second way to identify black beans is to look at their appearance. There are "little white dots" in the middle of real black beans. The "little white spots" of dyed black beans will be dyed.

5. To identify black beans, first wipe the skin. Dip the black beans in some water and then rub them on white paper. The color of real black beans will not fade even if you rub them hard on the white paper. The color of the dyed black beans will leave color on the white paper after friction.

When buying black beans, carefully identify them according to the above 5 points, and you will buy real black beans and will not be deceived by those unscrupulous vendors.
