How to distinguish the authenticity of black rice

Compared with rice and millet, black rice has higher nutritional value, and black rice is a black food, which has a good regulating effect on promoting the body's absorption and helping the body regulate melanin. The price of black rice in the market is not very cheap. In addition, even if you buy real black rice, there may be counterfeiting. So how to distinguish the authenticity of black rice?

How to distinguish true and false black rice:

1. Look at the color. The surface of normal black rice is shiny, while the dyed black rice is dull.

2. Look at the epidermis. The epidermis of normal black rice will be flaky when scratched with your fingernails. If it is powdery, it is low-quality black rice.

3. Look at the core of the rice. The core of normal black rice is white. The core of ordinary rice is transparent and has no color. If dyed black rice is made from regular rice, the color of the dye will penetrate into the center of the rice and turn it black.

4. Look at the water used to soak rice. Normally, the water used to soak black rice is purple-red, and after dilution it is also purple-red or reddish. If the water that comes out of the rice remains black after being diluted like ink, then it is definitely fake rice.

5. Add white vinegar. The black rice water will turn green when it encounters alkali and turn red when it encounters acid. Authentic black rice water will turn red immediately when it comes into contact with acid. Precautions

6. When buying black rice, you must observe it carefully. If you are not sure about the first four points, use the fifth point, which will work all the time.
