Differential staining method
1. Rub black beans with your fingers repeatedly, or draw them back and forth on clean white paper. If there are black spots, it means dyed black beans.
2. There are white spots on real black beans. If the black beans are dyed, the white spots will also be dyed black. In addition, you can also carefully observe the color of the skin of black beans. The inner skin of true black beans is white, and the inner skin of dyed beans will also be dyed black.
3. There are chemicals on the surface of dyed black beans, so the "soaking water" will have a pungent taste, while the undyed black bean soaking water has no taste.
4. The surface of natural black rice is bright and uniform, and the color of dyed black rice will be dull.
5, true black sesame seeds will not appear dark black when soaked in water, but translucent brown.
