According to the Changde Evening News (reporter Zeng Ling) after the black beans bought back in the market were soaked in water for a period of time, the water turned purple-red. The day before yesterday, Ms. Zhou called the newspaper's news hotline to say that the black beans she bought may have quality problems. Are these black beans dyed? Ms. Zhou hopes to figure it out.
On the afternoon of November 16, Ms. Zhou bought two kilograms of black beans from a grain and oil store near the Jianshe Bridge on Jianshe Road in the urban area of the city, and prepared to grind soy milk to drink. After going back, Ms. Zhou soaked the black beans, who knew that after soaking for a while, she saw that the water turned purple. "Will this be harmful to the body after eating it?" Ms. Zhou suspected that she had bought dyed black beans and did not dare to eat them anymore.
The afternoon before yesterday, the reporter came to the grain and oil store, only to see a large pile of bulk black beans in a large wooden trough, and several customers were buying. The staff on the side said that the product has a formal inspection report and can be purchased with confidence. Mr. Chen, the owner of the grain and oil store, said that before the black beans were purchased, the grain and oil stores had reviewed the relevant test reports, product descriptions and other materials. The black beans in the supermarket are the same as the goods they buy. If Ms. Zhou is still worried about this, they are willing to refund the money.
Subsequently, the reporter contacted the Seed Management Section of the Municipal Bureau of Agriculture, and the person in charge, Chief Gong, introduced that many of the grains and grains are born with some colors, such as black beans, mung beans, black sesame seeds, etc. These grains themselves contain natural pigments, which are divided into fat-soluble pigments and water-soluble pigments, the latter of which are soluble in water. Therefore, when cleaning and cooking these grains, it is not surprising that they fade.
"The water soaked in black beans turns purple or burgundy red. This is because after the black bean matures, it contains water and pigments, and some pigments will be soaked out after being soaked in water for a long time, which has no effect on the human body. Citizens can eat with confidence. The head of the Food Supervision Section of the Municipal Bureau of Industry and Commerce said that according to the market spot check, there are no dyed black beans in our city at present.
