Potassium ferrocyanide (formula - E536) is a rather dangerous chemical additive, which is forbidden to be used in the process of manufacturing various products in some countries. In our country, this prohibition does not exist and E536 is actively added to ordinary table salt to perform anti-caking action (an obstacle to the formation of clodiness of salt). Also, this additive is widely used in a variety of technologies as an clarifier.
The following names of this supplement are also encountered, which manufacturers use to indicate the composition of their products: potassium hexacyanoferriate, hexacyanoferrate II, potassium trihydrate, FSW, ferrocyanide syrup potassium, yellow blood salt, potassium hexacyanoferrate, Kaliumferrocyanid (from German), ferrocyanidedephere. The component belongs to the group of food additives, in the form of anti-caking additive, emulsifier and clarifier.
Raw natural salt has a grayish tinge (yes, at first glance it looks dirty and ugly). In the process of adding E536 salt acquires a white and clear shade, therefore, it acquires a more attractive and aesthetic appearance for the consumer, which plays into the hands of manufacturers, as the appearance of the product as a result allows to significantly increase the price for such a popular product among consumers.
Some rather enterprising manufacturers add the additive E536 as an emulsifier in winemaking, in the production of sausages. Potassium ferrocyanide is also added to the production process of certain types of cheese. In cheese, this food additive acts as an emulsifier and gives uniformity to the color of this dairy product.
Also, an additive is added to inexpensive cottage cheese varieties in order to improve its color and give a crumbly consistency to the product (an indicator of the presence of E536 in the curd is the same, crumbly cheese grains).
Finding potassium ferrocyanide in cheese is harmful to the human body and you can get a lot of side effects that will be as difficult as possible to eliminate. It should be borne in mind that hard cheeses are included in the diet of young children, pregnant women, women during lactation, postoperative diets, the diet of the elderly, and the presence of potassium ferrocyanide in this dairy product can trigger irreversible processes in various body systems.
To determine the presence of potassium ferrocyanide in the product is quite simple. Such products are characterized by whitish plaque on the shell.
Therefore, if during the period of inspection of the product there is a white patina on the packaging of cheese, sausage or other product, it is recommended to refuse to buy and choose a different type of product.
What danger is fraught with E-536
In our country, the use of this additive in the food industry and in the chemical industry is allowed, but there are certain restrictions on its quantity. For salt, the allowable rate is up to twenty milligrams of E536 per kilogram of product. But it should be borne in mind that even in such small quantities potassium ferrocyanide can cause serious harm to the body.
There are a number of problems that may arise due to the use of potassium luminolferroncyanide:
- severe intoxication of the organism as a whole;
- severe dysfunction of the lymphatic system;
- various stages of impaired functioning of the nervous system;
- the manifestation of problems with the skin (dermatitis, acne, acne, purulent inflammation);
- disruption of the liver and gallbladder;
- violations of the digestive tract.
A powder with a small fraction of yellow crystals is a chemically synthesized additive that is obtained in the gas cleaning process at gas plants.
From the very name of potassium ferrocyanide, it becomes clear that there are cyanide compounds in the composition of this supplement. Probably everyone knows how cyanic potassium is harmful to the human body. Toxic additive E536 can be obtained in different ways and it varies the amount of cyanides and hydrocyanic acid. If the additive gets into the stomach, contact with the stomach acid is observed, as a result, dangerous hydrocyanic acid and toxic gases will be released.
Scientists do not comment on the situation with the use of this most dangerous emulsifier, especially where it can be abandoned.
Today, potassium ferrocyanide is produced from already spent materials, which contain a large amount of cyanide compounds.
This additive does not completely smell, with a bitter-salty taste. Additive density - 1.85 grams per centimeter cubic. By maintaining a normal room temperature with completely dry air, this food additive will not decompose on contact with air.
Toxicity reaches its maximum when the additive comes into contact with water, as serious toxic gases begin to be released. The harm and benefits of this supplement are currently being actively studied in many countries in order to determine the possibility of using E536 in any industry.
During the period of buying various products, you should carefully study the labels indicating the composition, and, if possible, avoid buying products with the presence of E536, because if you use this supplement improperly (if the technology is broken), you can provoke hard and even fatal consequences for the human body.
Use of E536 in industry
Potassium ferrocyanide is actively used not only in the food industry, but also not in the food industry, in the form of dyes for fabrics and paper, as a utilizer of radioactive coal, or as fertilizer. The maximum dose in our country of use of this supplement is ten milligrams per kilogram of product.
In case of a large amount of E536 in dyes, etc. You can provoke the following reactions: allergic rash, redness, itching, ulcers, headache, mucous membranes, etc.
The effect of potassium ferrocyanide on humans in any case will have, therefore, its use should be limited to the maximum.
