Sorbic acid Chemical Properties,Uses,Production

Chemical Properties

White, crystalline solid. Slightly soluble in water and many organic solvents. Combustible.

Chemical Properties

(E,E)-2,4-Hexadienoic acid has a characteristic odor.


sorbic acid is a broad-spectrum, non-toxic preservative against molds and yeasts with moderate sensitizing potential in leave-on cosmetics. It is used in concentrations of 0.1 to 0.3 percent, and its activity is dependent on the formulation’s pH. Sorbic acid is used as a replacement for glycerin in emulsions, ointments, and various cosmetic creams. It is obtained from the berries of the tree commonly known as mountain ash and rowan, and can also be produced synthetically. Sorbic acid can cause irritation.


Sorbic Acid is a preservative that is effective against yeasts and molds. it is effective over a broad ph range up to ph 6.5, being ineffective above ph 7.0. it is a white, free-flowing powder which is slightly soluble in water with a solubility of 0.16 g in 100 ml of water at 20°c. its solubility in water increases with increasing temperatures, although it is not recommended in foods that are pasteurized because it breaks down at high temperatures. the salts are potas- sium, calcium, and sodium sorbate. it is used in cheese, jelly, bever- ages, syrup, and pickles. typical usage levels range from 0.05 to 0.10%.


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.


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.


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.

Biotechnological Production

Today, sorbic acid is produced solely by chemical synthesis. However, fermentation and chemical synthesis might be combined to develop a new production route for sorbic acid . In a first step, glucose would be converted to triacetic acid lactone by fermentation. It has been shown that triacetic acid lactone can be produced by genetically modified E. coli and S. cerevisiae strains. After a separation from the fermentation broth, triacetic acid lactone would be transformed into butyl sorbate in a multistage catalyst system (catalysis-hydrogenation and solid acid catalysis). Then, butyl sorbate would be purified and hydrolyzed to sorbic acid. Different scenarios are analyzed to evaluate the economic feasibility of such a production process .

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.


Sorbic acid and its salts have broad-spectrum activity against yeast and molds, but are less active against bacteria. The antimicrobial action of sorbic acid was discovered independently in the United States and Germany in 1939, and since the mid-1950s sorbates have been increasingly used as preservatives. Sorbates generally have been found superior to benzoate for preservation of margarine, fish, cheese, bread, and cake. Sorbic acid and its potassium salts are used in low concentrations to control mold and yeast growth in cheese products, some fish and meat products, fresh fruits, vegetables, fruit beverages, baked foods, pickles, and wines. Sorbic acid is practically nontoxic. Table 10.4 shows acute toxicity of sorbic acid and its potassium salt. Animal studies have not shown obvious problems in tests performed with large doses for longer time periods. When sorbic acid (40 mg/kg/day) was injected directly into the stomach of male and female mice for 20 months, no differences were observed in survival rates, growth rates, or appetite between the injected mice and the control. When the dose was increased to 80 mg/kg/day for three additional months, however, some growth inhibition was observed. When potassium sorbate (1 and 2% in feed) was fed to dogs for three months, no pathological abnormalities were observed. This evidence indicates that the subacute toxicity of sorbic acid is negligible.
As a relatively new food additive, sorbate has been subject to stringent toxicity-testing requirements. It may well be the most intensively studied of all chemical food preservatives. In 90-day feeding studies in rats and dogs and a lifetime feeding study in rats, a 5% dietary level of sorbates procured no observable adverse effects. However, at a 10% dietary level in a 120- day feeding study, rats showed increased growth and increased liver weight. This has been attributed to the caloric value of sorbate at these high dietary levels since it can act as a substrate for normal catabolic metabolism in mammals. Sorbates are not mutagenic or tumorigenic, and as noted previously, no reproductive toxicity has been observed.

Safety Profile

Moderately toxic by intraperitoneal and subcutaneous routes. Mildly toxic by ingestion. Experimental reproductive effects. A severe human and experimental skin irritant. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use water. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

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