How to identify black beans,

How to identify black beans:

1. There are two types of black beans. If they are distinguished by the kernels of black beans, one kind of black bean kernel is yellow; the other is green kernel (green) Black beans, long bean sprouts that can turn green, are generally used for medicinal purposes. I used to think that only green beans were real black beans, but I was actually wrong. Black beans also have yellow kernels. Some people even said that there are white ones. I haven’t bought them yet, so I won’t discuss them yet;

2. Black beans are divided into Both medicinal and edible. Medicinal black beans have green hearts, while edible black beans have yellow hearts.

3. To identify black beans, first, look at the bean clothing. When the real black beans are peeled off, the inside is white. Because the bean coat is very thin, the color of the dyed black beans will penetrate into the inner skin. After peeling off the black bean coat, you can see that the inside of the black bean coat will also change color. The skin of real black beans is bright and shiny. If it is blurred due to transportation, just rub it with your hands and it will be shiny, while fake black beans will have no luster no matter how you rub it;

4. Identification For black beans, the second thing is to look at the appearance. Real black beans have "little white dots" in the middle. The "little white spots" of dyed black beans will be dyed.

5. To identify black beans, the third is to rub the skin. Dip the black beans in some water and rub them on white paper. Real black beans will not fade when rubbed hard on the white paper. The color of dyed black beans will leave color on the white paper after rubbing.
