Then it is very likely to be artificially colored black rice.

According to relevant experts from the agriculture department, it is an abnormal phenomenon for black rice to lose color when put into water. The surface of natural black rice has water-soluble pigments, and soaking in water will also cause a certain degree of fading. It was also learned that currently in China's grain testing methods and standards, there are no specific technical standards and specifications for black rice, so it is difficult to detect whether black rice has been dyed. But one thing is for sure: identifying real or fake black rice by seeing if it loses color when soaked in water is unreliable. Since black rice itself has a fading reaction, how can we distinguish the quality of black rice? Relevant personnel said that currently, there are two common situations of adulteration of black rice in the market. One is that black rice with longer storage time, inferior or poor quality black rice, is sold as good quality after being dyed; the other is that ordinary rice is dyed and sold as black rice. Natural black rice will also fade after washing with water, just not as much as dyed black rice. Consumers can identify black rice from the following aspects:

1. Look: Observe the color and appearance of black rice. Generally, high-quality black rice has a luster, uniform size of grains, very few broken rice or cracked grains (cracks on the rice), no insects, and no impurities. Inferior black rice has a dull color, uneven grain size, poor fullness, more broken rice, insects, clumps, etc. For dyed black rice, since the black color of black rice is concentrated in the outer layer, the endosperm is still white. Therefore, consumers can scrape off the entire outer layer of the rice grain and check if the inside is white. If it is not white, it is highly likely to be artificially dyed black rice.

2. Smell: Smell the odor of black rice. Take a small amount of black rice in your hand, exhale a puff of warm air onto the black rice, and then immediately smell the odor. High-quality black rice has a normal fragrant smell and no other strange odors. If there is a slight strange smell or moldy smell, sour smell, decayed smell, or any abnormal smell, it is inferior black rice.

3. Taste: Taste the flavor of black rice. Take a small amount of black rice and chew it carefully in your mouth, or grind it and taste it. High-quality black rice tastes good, slightly sweet, and has no strange odor. If it has no taste, a slight strange smell, sour taste, bitter taste, or other unpleasant tastes, it is inferior black rice.

News Link: Benefits of Black Rice: Black rice is a type of rice that can be used both as food and medicine. According to legend, more than two thousand years ago during the reign of Emperor Wu of Han, it was first discovered by Zhang Qian, the Marquis of Bo Wang. Traditional Chinese medicine believes that black rice has significant medicinal value. Ancient agricultural and medical books record that black rice has functions such as "nourishing yin and replenishing kidneys, strengthening health and warming the stomach, brightening eyes and activating blood, clearing liver and moistening intestines, lubricating dampness and benefiting essence, replenishing lungs and relaxing tendons," and can be used as medicine and food. It is especially effective for treating dizziness, eye strain, anemia, premature graying of hair, soreness of waist and knees, night blindness, and tinnitus. Long-term consumption can prolong life and enhance vitality.

Black rice is rich in nutrients and is also called "black tribute rice." Zhang Qian, the pioneer of the Western Han Dynasty's "Silk Road," discovered this miraculous rice and presented it to Emperor Wu of Han. After tasting it, Emperor Wu praised it as "divine rice," and it has been enjoyed by emperors throughout history ever since.

Black rice contains inorganic salts such as manganese, zinc, and copper, as well as special components like vitamin C, chlorophyll, anthocyanins, carotene, and cardiac glycosides. Traditional Chinese medicine believes that black rice has the effects of nourishing yin and replenishing kidneys, strengthening the spleen and warming the liver, brightening the eyes and activating blood circulation. It can treat various conditions such as anemia, dizziness, blurred vision, premature graying of hair, etc.
