Sodium Benzoate, Powder, NF & FCC

CAS: 532-32-1

Meets Specifications of the Food Chemical Codex  and United States Pharmacopeia

As a food additive  Sodium Benzoate is used as a preservative, effectively killing most yeasts, bacteria and fungi. Sodium benzoate is effective only in acidic conditions (pH < 3.6) making its use most prevalent in foods such as preserves, salad dressings (vinegar), carbonated drinks (carbon dioxide), jams (citric acid), fruit juices (citric acid), and chinese food sauces (soy, mustard, and duck). It is also found in alcohol-based mouthwash. More recently, sodium benzoate has become apparent in many soft drinks, including Sprite, Fanta, Sunkist and Dr Pepper. It can be identified in soft drinks by 'sodium benzoate' or E211. The taste of sodium benzoate cannot be detected by around 25 percent of the population, but for those who can taste the chemical, it tends to be perceived as sweet, salty, or sometimes bitter.

Sodium Benzoate  is found naturally in cranberries, prunes, greengage plums, cinnamon, ripe cloves, and apples. Concentration as a preservative is limited by the FDA in the U.S. to 0.1% by weight though organically grown cranberries and prunes can conceivably contain levels exceeding this limit. The International Programme on Chemical Safety found no adverse effects in humans at doses of 647-825 mg/kg of body weight per day.
