substance sodium benzoate is known as a food additive (E211), which is classified in the group of preservatives.This - sodium benzoate.Externally, the compound is a white powder which is odorless, or it may be a little smell of benzaldehyde.
first substance was obtained in 1875 by the American researcher Hugo Vleck and was invited by him as a substitute for salicylic acid.Already in 1908, sodium benzoate has been admitted to the United States for use as a preservative.Its preservative effect based on the fact that the sodium benzoate is able to significantly decrease the activity of enzymes that are present in the cell, which provide redox reactions, and thereby significantly reduce the effectiveness of yeasts and molds.This action tend preservatives potassium sorbate and sodium benzoate.There is a small amount of this compound in natural foods.Among these, you can specify the apples, raisins, mustard, and others.
chemical formula of the substance - C6H5COONa, but it is an empirically derived equation.
As a dietary supplement, registered under the part number (E211), sodium benzoate, approved for use in many countries around the world, including in Russia.Specialists at this time is an active discussion on the combined health hazards of substances, which include sodium benzoate, and some dyes simultaneously.The fact is that given the scientific evidence of the harm that can be caused by the interaction with dyes benzoate E110, E104 and others.
widely used in industrial production, especially in the food industry.Here it is used for preserving meat and fish products, margarine, different varieties of mayonnaise and ketchup.If sodium benzoate is used in products that contain in its composition vitamin C, then reacting with it can lead to a dangerous high concentrations of carcinogenic benzene.
as preservatives, sodium benzoate is used in the production of cosmetics and pharmaceutical preparations.In the latter case, it is a part of expectorants and other combined drugs such purpose.
common to use sodium benzoate and for technical purposes.For example, in aviation it are used as a main component coatings for protection from the harmful effects of various airframe components made of aluminum.Moreover, also used as a plating in various industries associated with this process.
appointment Pyrotechnic substance is its ability to mimic the sound of a rocket taking off.
In 1999, biologist Piper PA in one of his works suggested that benzoate, under the action of yeast cells, can cause so-called "oxidative stress".It was also stated about the presence of the substance mutagenic activity, which is distributed primarily in the human DNA.Here it is necessary to make a reservation that Piper examined not only how impacts of sodium benzoate, and other organic acids, which are used as preservatives.
Later, scientist said the harm that may be associated with the presence of benzoate associated with the risk of Parkinson's disease.
In accordance with the requirements of the WHO stated in CICAD26 of 2000, various studies of character of influence of sodium benzoate on humans showed the relative safety of this compound.However, the document states that can occur cases of skin allergies (dermatitis), and exacerbate asthma.
