Sodium Benzoate is primarily used as a preservative in the food and beverage industries. It also is used as a preservative in cosmetic products and as a corrosion inhibitor in automotive and other antifreeze products. Velsicol offers three forms of sodium benzoate -- Probenz?SG (Sodium Benzoate Granular), Sodium Benzoate (Powder) and Sodium Benzoate EF(Extruded). All conform to FCC Food Grade / E211 / EP Grade specification requirements.

Sodium benzoate Chemical Formula: Synonyms Benzoate of soda Description White powder or crystals. Sodium benzoate converts to benzoic acid when use in acidic mixtures. Benzoic acid has good anti-microbial features, but does not dissolve well in water, whereas sodium benzoate dissolves very well in water. Sodium benzoate is used in acidic foods and products to control bacteria, mold, yeasts, and other microbes. It interferes with their ability to make energy. Because it only converts to benzoic acid in acidic environments, it is not used for its anti-microbial action unless the pH is below about 3.6. In the food industry, it is used in items such as jams, salad dressing, juices, pickles, and carbonated drinks. It is also used as a corrosion inhibitor in automotive anti-freeze products. Sodium benzoate, also known as benzoate of sodium, is the sodium salt of benzoic acid. It is a polyunsaturated fat. Physical and Chemical Properties appearance- white granules or crystalline powder odor- odorless solubility- soluble in water (1gm/ 2mL water) density- 1.44 boiling point- not applicable melting point- >300oC (>572oC) Figure 1. Structure of sodium benzoate Sodium benzoate is used as a preservative in food. It prevents the growth of almost all microorganisms. It's concentration is limited to 0.1% because it is poisonous. Sodium benzoate works best in acidic environments and is used in such foods as salad dressing, pickles, fruit juices, and carbonated drinks. It is also used in medications like Actifed and Tylenol. Figure 2. Orange soft drinks contain a high amount of sodium benzoate. Figure 3. Sodium benzoate is also found in the pain reliever Tylenol.

Date: Mon Sep 18 20:29:47 2000 Posted By: Gil Stoewsand, Faculty, Food Science & Technology, Cornell University Area of science: Chemistry ID: 966712600.Ch -------------------------------------------------------------------------------- Message: Sodium benzoate is a very widespread food preservative used much under 0.1% in many foods from soup to cereals. The considerable time between the production and the consumption of food today makes some use of preservatives necessary in order to prevent spoilage and undersirable alterations in color, flavor, or nutrients. Degradation pathways for benzoic acid (produced in the body from the sodium salt) have been studied in detail and have shown the harmlessness of this substance: 75-80% is excreted within 6 hours, and the total dose leaves the body within about 10 hours. It does not cause cancer. The limit of sodium benzoate in foods is not because of its toxicity, but at levels higher than 0.1% will leave an unacceptable aftertaste. Foods containing this preservative are much healthier than non-preservative foods since harmfull microorganism growth is inhibited, food oxidation is prevented, and food nutrients are preserved. Chronic toxicities were examined in rats fed diets containing up to a total of 1%. After 4 generations there were no changes in normal patterns of growth, reproduction, lactation and no morphological abnomalities of organs. Acute toxicity studies, where one large dose of sodium benzoate is given to animals, showed no lethal effects until 2 grams per kg. body wt. was administered. One could not eat enough foods containing sodium benzoate to even get 0.002% of this amount! Limits of sodium benzoate in foods is not because of toxicity, but it will impart a taste that will make some foods unacceptable. This is a very non-toxic compound and foods containing presevatives are usually much healthier since harmful microorganism growth is inhibited, oxidation is checked, and nutrients, natural or added, are saved.
