How to distinguish the real from the fake.

Rub by hand: Rub the rice with your hands to see if there is dye on your hands, if there is black dye, it is fake rice.

Nose smell: Authentic black rice has a natural rice fragrance after being soaked in warm water, and dyed rice has a peculiar smell.

Look at the color: The skin of authentic black rice is shiny, and the color is dark and light, while the dyed black rice is not shiny and the color is consistent.

Look at the epidermis: The epidermis that authentic black rice scratches with fingernails is flaky. If it's in powder form, it's low-quality black rice.

Look at the rice heart: The rice heart of authentic black rice is white. The kernel of ordinary rice is transparent and has no color. If the dyed black rice is dyed with regular rice, the color of the dye will penetrate into the heart of the rice and turn black.

Look at the soaked rice water: The soaked rice water of authentic black rice is purple-red, and it is also purple-red or reddish after dilution. If the soaked water is still black after being diluted like ink, it must be fake rice.

Add white vinegar: Black rice water will turn green when it encounters alkali and turn red when it encounters acid. Authentic black rice water turns red immediately when it encounters acid.

Randomly take some grains of black rice and put them into the cup, pour white vinegar into the cup, stir thoroughly, after a while, the white vinegar turns red into real black rice, and turns black into fake black rice.

Black rice itself is natural, and black color tends to fade. When you look at the white inside and the color of the inside, the surface layer and the inside are distinct, indicating that it is natural black rice. If the outer skin layer of black rice is scraped off, the white color of the rice grains is not pure, indicating that it is artificially dyed black rice.

Generally, black rice is shiny, the size of rice grains is uniform, there are few broken rice, cracks, no insects, and no impurities. The color of inferior and inferior black rice is dull, and high-quality black rice has a normal fragrance and no other peculiar smell. Inferior and inferior black rice has a slight peculiar smell or abnormal odor such as mildew odor, sour odor, and rotten smell.

Place a small handful of rice on soft paper (or toilet paper) soaked in water and rub it by hand until the paper is noticeably black, most likely dyed rice.

The first trick is to look at the gloss. The normal epidermal layer of black rice is shiny, and low-quality black rice has no luster.

The second trick is to look at the epidermis. Normal black rice is flaked when picked by hand, and if it is powdered, it is inferior black rice.

The third trick is to look at the rice heart. The kernel of normal black rice is white, while the kernel of regular rice is transparent and has no color. Black rice dyed with rice has a uniform appearance, but the color of the dye penetrates into the heart of the rice.

The fourth trick is to soak in rice water. The soaked rice water of normal black rice is purple-red, and it is also purple-red or nearly red after dilution. If the water bubbled out is like ink, and it is still black after dilution, this is fake black rice.
