Sodium formate (E237) is a preservative responsible for ensuring that food and preparations do not deteriorate and retain important qualities for as long as possible.
Food supplement prevents the appearance of fungus and various bacteria. It has certain antimicrobial effects, but only when immersed in an acidic environment. Sodium formate is a gray, white and sometimes greenish crystalline powder. It is highly soluble in water, but practically insoluble in alcohols and ethers.
The substance is non-flammable and non-explosive, but at the same time, when working with sodium formate, smoking and open access to fire are not allowed.
Sodium formate can be seen in the composition of many liquids – in the juices of certain plants and the biological fluid of a living organism.
This dietary supplement is banned in some countries (United States of America, European Union, Russian Federation).
Application of food additive
Permissible daily dose – 3 mg per 1 kilogram of human weight. Previously, Russia allowed the use of a preservative in the production of lemonades and other soft drinks. At the same time, no more than 210 mg per 1 liter of drink was allowed. Or in combination with benzoates – less than 360 mg per liter of drink.
Until recently, this substance was used for fish marinades, for marinating vegetables and for replacing salt in dietary nutrition. At the moment, they began to be replaced by safer additives.
In addition to the food industry, sodium formate is added to some medicines. For example, Medichronal. It is also used for the preservation of certain cosmetic preparations, for tanning leather, for dyeing fabrics and printing wallpapers.
