sorbic acid usage and synthesis |
chemical properties | crystalline |
usage | 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. |
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. |
