I bought black rice soaked in water overnight even soaked with soybeans are discolored that black rice to cook and eat the whole pot of rice into purple and black I do not know if my black rice is false Black rice after being run over is going to change color, but it is to turn purple-red. Because there are anthocyanins on its skin, in hot or cold water slightly soaked, will bring color out. Normal black rice water is purplish-red, and after dilution, it is also purplish-red or close to red. This is the normal color of black rice. If the bubble out of the black rice water like black ink, that is certainly not right, diluted or black, this black rice is not good black rice.
