How to distinguish the authenticity of black beans

1. Look at the appearance

There is a small white dot in the middle of the real black bean. If it is dyed, the small white dot will of course change color. The authentic pure black beans are not uniform in size, some are large and some are small, and the color is not pure black. Some are jet black, and some are black with a reddish tint. Fake black beans are basically dyed, and the whole body is jet black, with a relatively uniform size, and the traces of artificial processing are more obvious.

2. Rub the epidermis

If you rub the real black beans on white paper, they will not fade, but the color of dyed black beans will leave marks after rubbing. When purchasing, you can rub the black beans in the palm of your hand to see if they fade. If they do, it means that the black beans are of poor quality.

3. Soak in vinegar

Put black beans into white vinegar and stir. If the white vinegar turns red, it is pure black beans. If the vinegar does not change color, it is fake black beans. The reason why black beans and white vinegar change color is because they contain anthocyanins on their surface. It is this chemical reaction of anthocyanins with white vinegar that changes color. This is the most accurate identification method.
