Why does black rice fade? How to identify the authenticity of black rice?

1. Why does black rice fade?

It is normal for black rice to fade in color, and it does not necessarily mean that it has been dyed. Because the surface of black rice is relatively rough, and the core of the rice is white, its black surface contains some water-soluble pigments, which are called anthocyanins. This substance will decompose when it comes into contact with water, resulting in the discoloration phenomenon that people see.

2. Identify the authenticity of black rice by its appearance

When you buy black rice, you can look at the appearance to identify the authenticity. Good quality black rice has a shiny surface, and the rice grains are uniform in size, with small broken rice, and there are no insects or defects. Poor quality black rice has no luster, is uneven in size, and has many broken rice. In addition, when buying black rice, you can also remove its surface layer to see if the rice core is white. If it is not white, then the rice is fake.

3. Identify black rice by smelling it

When buying black rice, you can identify it by its smell. The best way is to take a small amount of black rice in your hand, blow a breath of hot air on the black rice, and then smell it immediately. If you can smell a fresh fragrance, it means that it is real black rice of good quality. If there is no fragrance, or there are other peculiar smells, it means that the quality of the black rice is poor or it has become moldy.
