Sometimes some consumers go home to cook black beans will also encounter this situation, the reason for this is actually very simple, this is because the black bean skin so-called for black, because the black bean skin contains anthocyanins, and anthocyanins encountered in the white vinegar is going to have a chemical reaction, so we will see that the white vinegar becomes red, and dyed black beans, it is impossible to contain anthocyanins in the skin of the black bean, so naturally it will not be changed in color. The dyed black beans, it is impossible to contain anthocyanins in its black bean skin, so naturally it will not change color.
