What is Sudan red?
"Sudan Red" is not a food additive, but a chemical stain. Its chemical composition contains a compound called naphthalene, which has azo structure. Because of the nature of this chemical structure, it is carcinogenic and has obvious toxic effects on liver and kidney organs of human body. Sudan red belongs to chemical dyes, which are mainly used in petroleum, engine oil and other industrial solvents, with the purpose of brightening it, and also used to brighten shoes and floors.

What's the difference between "Sudan Red No.1" and "Sudan Red No.4"?

There are four kinds of Sudan red, I, II, III and IV. Toxicological studies show that Sudan red has mutagenicity and carcinogenicity. Sudan red (No.1) has the characteristics of possible carcinogenicity in the study of human hepatocytes, and it is forbidden to be used in food in China.

The main structures of "Sudan Red No.4" and "Sudan Red No.1" discovered this time are the same, both of which are carcinogenic, but there are some differences, so they are labeled as No.1 and No.4..

"Sudan Red No.1" pigment is a kind of red dye, an artificial chemical preparation, which is forbidden to be used in food production in most countries in the world. This pigment is often used in industry, such as solvent, engine oil, wax and gasoline, and shoes and floors. Sudan Red (No.1) has the potential to cause cancer in the study of human hepatocytes. But at present, it is only found to be carcinogenic in mouse experiments, and its carcinogenicity to human body is not clear.

Is Sudan Red a food additive?

China has a strict examination and approval system for food additives. China has never approved the use of "Sudan Red" dye in food production. This "Sudan Red" incident is similar to "sodium formaldehyde sulfoxylate" and "clenbuterol", both of which are illegal additives added to food by food production enterprises.

what are the differences between food additives such as carmine and sunset yellow and Sudan red?

Although it is difficult for ordinary citizens to determine which foods contain Sudan red, there is no need to be afraid of "red" and "spicy". In addition to Sudan red, there are thousands of edible red colorants, such as carmine, magenta, amaranth, etc. These colorants can be added in limited quantities in food. Quality supervision experts said that they are essentially different from "Sudan Red". The first two are food additives listed in the national catalogue and can be used in some foods. However, the state has strict limit regulations and it is strictly forbidden to use them in excess. There is no safety problem when using food additives within the standard range.

why is Sudan red spicy?

An industry insider analyzed that Sudan red, as a chemical raw material, was added to food, especially used in the processing of pepper products:

First, Sudan red is not easy to fade after use, which can make up for the discoloration of pepper after long-term storage and keep the bright color of pepper;

Secondly, some enterprises dye corn and other plant powders with Sudan red and then mix them with Chili powder to reduce costs and gain profits.

What is the harm of "Sudan Red"?

On June 14th, 24, the British Food Standards Authority issued a warning to consumers and trade organizations about Sudan Red No.1 pigment found in a batch of new foods in supermarkets, and banned Sudan Red No.1 in the product catalogue.

in p>22, researchers found that they can cause DNA mutation in human liver cells. After "Sudan Red No.1" enters the organism, it will not cause illness soon. Exposure to substances that can cause cancer does not mean that cancer will definitely occur.

An official from Cancer Research UK said that compared with common cancer-causing factors such as smoking, the cancer risk caused by "Sudan Red One" is very small. She said: "Even if people have eaten the food listed on the list, there is no need to panic." However, according to the regulations of the European Union, all dried, crushed or ground peppers entering any European Union country cannot contain "Sudan Red No.1". The relevant goods that cannot produce certificates will be detained for sampling and analysis. Ports and local governments should also randomly take samples for inspection. Once the food is found to contain "Sudan Red No.1", it must be completely destroyed.

Sudan red is mutagenic and carcinogenic, and Sudan red (No.1) has the characteristics of possible carcinogenicity in the study of human hepatocytes. But at present, it is only found to be carcinogenic in mouse experiments, and its carcinogenicity to human body is not clear. Sudan red is a chemical dye, and the amount added to food is very small. As far as dosage is concerned, it may not be enough to cause cancer, so the public need not panic too much. A small amount of food can't cause cancer, even if it is eaten for half a year, there is no clear scientific basis for causing cancer. People don't have to worry about cancer just because they eat a little. .

Experts believe that although "Sultan I" will increase the risk of cancer among consumers, it is impossible to determine a safety level at present.

It is recommended that regular consumers check the liver

Studies show that "Sudan Red No.1" is carcinogenic, which will cause cancer in rats, and it also shows the characteristics of possible carcinogenicity in the study of human hepatocytes. Because this kind of dye, which is regarded as food pigment, will only slowly affect the health of consumers, but will not cause disease quickly, so it is very concealed.

Long-term consumption of food containing "Sudan Red" may change the DNA structure of the liver and lead to liver diseases.

how to identify Sudan red?

In addition, there is a simple and easy way to exclude Sudan Red. If people suspect that a colorant may be Sudan Red, they can see whether it is soluble in water, soluble in water and soluble in organic solvents such as chloroform. Members of the public can also visit the website of www.aqsiq.gov.cn (AQSIQ) to inquire about relevant methods.
