Sorbic acid Chemical Properties,Uses,Production

Chemical Properties

Crystalline

Uses

Sorbic Acid is an naturally occurring organic compound first isolated from unripe berries. Sorbic acid has been used as a food preservative and as an inhibitor of Clostridium Botulinum bacteria in mea t products in order to reduce the amount of nitrites which produce carcinogenic nitroamines.

Definition

ChEBI: A sorbic acid having trans-double bonds at positions 2 and 4; a food preservative that can induce cutaneous vasodilation and stinging upon topical application to humans. It is the most thermodynamically stable of the four possible geometri isomers possible, as well as the one with the highest antimicrobial activity.

Uses

Mold and yeast inhibitor. Fungistatic agent for foods, especially cheeses. To improve the characteristics of drying oils. In alkyd type coatings to improve gloss. To improve milling characteristics of cold rubber. See also Potassium Sorbate.

General Description

White powder or crystals. Melting point 134.5°C. Slightly acidic and astringent taste with a faint odor.

Air & Water Reactions

Soluble in hot water [Handbook of Chemistry and Physics]. May be sensitive to exposure to air and heat. The dust may become explosive, particularly when mixed with free-radical initiators or oxidizing agents. .

Reactivity Profile

Sorbic acid may discolor on exposure to light. Can react with oxidizing agents. Also incompatible with bases and reducing agents. The dust may become explosive, particularly when mixed with free-radical initiators or oxidizing agents .

Fire Hazard

Sorbic acid is combustible.

Purification Methods

Crystallise the acid from water. Dry it air or in a desiccator over P2O5. [Beilstein 2 IV 1701.]
