Recently, the News on the Internet about "salt adding anti-caking agents will endanger health", the news said: Professor Yu of the Central Party School told us with personal experience how terrible salt additives are. Bad appetite, stuffy appetite, no desire to eat, aminotransferase rise - total bilirubin rise - creatinine rise, I finally found the anti-caking agent of table salt: potassium ferrocyanide!
Is this true?
First, let's understand what potassium ferrocyanide is.
Potassium ferrocyanide, commonly known as potassium yellow blood salt, is a light yellow crystalline granule. It is a food anti-caking agent allowed by the United Nations Codex Alimentarius Commission.
The China Internet Joint Rumor Suppression Platform pointed out that potassium ferrocyanide is an international legal additive.
Second, we need to know why table salt should add anti-caking agents.
Table salt is very easy to absorb moisture and agglomerate, and the lumps are very hard and difficult to break. For consumption, anti-caking agents are needed to keep the table salt loose.
Furthermore, how toxic is potassium ferrocyanide anti-caking agent?
On August 13, 2009, the Information Office of the Ministry of Health published an article entitled "Ministry of Health: Regulating the Use of Salt Anti-Caking Agents Will Not Cause Harm to Health" to debunk the news spread on the Internet. If potassium ferrocyanide is used according to the standard regulations, the daily intake is 0.15mg. According to the adult weight of 60 kg, the intake is 0.0025 mg/kg bw, which is much lower than the daily allowable intake of humans (0.025 mg/kg bw), so the use of potassium ferrocyanide according to the standard regulations does not cause harm to human health.

On February 7, 2018, the China Salt Industry Association published the "Explanation on the Recent Self-media Dissemination of False Information on the Harm to the Health of Consumers by Adding Potassium Ferrocyanide to Salt" issued by the National Salt Industry Standardization Technical Committee. The article points out that the chemical structure of potassium ferrocyanide is completely different from potassium cyanide, which can poison people, and its acute toxicity is lower than table salt.

People's Network Truth Seeking Column Science Popularization: According to national standards, the content of potassium ferrocyanide anti-caking agent added to table salt shall not exceed 10 mg per kilogram. This is equivalent to eating 150 grams (about one-third of a bag) of table salt per day for life, which is likely to cause chronic toxicity.
In addition, is the matter of Professor Yu in the online article true?
Ruan Guangfeng, director of the Science and Technology Department of the Food and Nutrition Information Exchange Center of Kexin, said: The identity of this so-called "Professor Yu of the Central Party School" is unknown, and the dialogue and details mentioned in the article cannot be verified at all, and the credibility is very low.
It can be seen that the online news is an old rumor for many years, and the official departments and authoritative media have debunked the rumors, so Mo is no longer deceived.
