Blood glutinous rice is black glutinous rice.

Blood glutinous rice is a type of rice with a purplish-red seed coat. Because the rice is glutinous, it is called blood phlegm. After soaking the glutinous rice in warm water, the red pigment of the seeds is dissolved by the water solution and a purplish-red aqueous solution appears, and the red color becomes thicker as time is prolonged. After cooking, the red seed coat will be separated from the embryo (rice).

Counterfeit blood glutinous rice is made from inferior rice, colored with purple-red pigment. The most obvious difference is that when immersed in water, the water reddens significantly faster than blood glutinous rice. When washed several times, the original shape of the white rice is exposed and no red seed coat appears after cooking.
