Sodium benzoate is a substance which has the chemical formula NaC7H5O2. It is a widely used food preservative, with an E number of E211. It is the sodium salt of benzoic acid and exists in this form when dissolved in water. It can be produced by reacting sodium hydroxide with benzoic acid.
Detailed description

Uses

Preservative

Sodium benzoate is a preservative. As a food additive, sodium benzoate has the E number E211. It is bacteriostatic and fungistatic under acidic conditions. It is most widely used in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (vinegar), and condiments. It is also used as a preservative in medicines and cosmetics.[3][4]Concentration as a food preservative is limited by the FDA in the U.S. to 0.1% by weight.[5] Sodium benzoate is also allowed as an animal food additive at up to 0.1%, according to AFCO's official publication.[6]

Pharmaceutical applications

Sodium benzoate is used as a treatment for urea cycle disorders due to its ability to bind amino acids.[7][8] This leads to excretion of these amino acids and a decrease in ammonia levels. Recent research shows that sodium benzoate may be beneficial as an add-on therapy (1 gram/day) in schizophrenia.[9][10][11] Total Positive and Negative Syndrome Scale scores dropped by 21% compared to placebo.
Sodium benzoate is used to treat hyperammonemia.[12]
Sodium benzoate has been shown to halt the progression of Parkinson's in mice.[12]

Other uses

Sodium benzoate is also used in fireworks as a fuel in whistle mix, a powder that emits a whistling noise when compressed into a tube and ignited.

Mechanism of food preservation

The mechanism starts with the absorption of benzoic acid into the cell. If the intracellular pH falls to 5 or lower, the anaerobic fermentation of glucose through phosphofructokinase decreases sharply,[13] which inhibits the growth and survival of microorganisms that cause food spoilage.
