What is Sorbic Acid?

Sorbic acid or 2,4-hexadienoic acid is a natural organic compound used as a food preservative. It has the chemical formula CH3(CH)4CO2H. It is a colorless solid that is slightly soluble in water, better soluble in oil, and sublimes easily. It was first isolated from the unripe fruit of Sorbus aucuparia (row ash) and was named after this tree.

The most common use of sorbic acid is in the food industry as an antimicrobial, versatile and safe preservative. Salts such as potassium sorbst and calcium sorbate are also used here. In general, salts are preferred to the acid form as they are more soluble in water, but the active form is acid. The optimal pH value for antimicrobial activity is below 6.5. Sorbates are generally used at concentrations of % 0.025 to % 0.10. However, adding sorbate salts to food slightly raises the pH of the food, so the pH may need to be adjusted to ensure safety.

Sorbic acid is found as a preservative in many foods such as cheese, meat products, fruit juices, dried fruits, instant soups, pickled cucumbers and bread & bread products. It prolongs shelf life by preventing microbial formations in these foods. It inhibits the growth of mold and yeast to a particularly high extent.

E numbers as food preservatives:

E200 Sorbic acid

E201 Sodium sorbate

E202 Potassium sorbate

E203 Calcium sorbate

Some molds (especially some Trichoderma and Penicillium species) and yeasts can produce trans-1,3-pentadiene by detoxifying sorbates by decarboxylation.

Pentadiene manifests as a typical kerosene or petroleum smell.

Other detoxification reactions include reduction to 4-hexenol and 4-hexenoic acid.

How is Sorbic Acid produced?

It was traditionally produced by the condensation of sorbic acid, malonic acid and crotonaldehyde. Second, allyl chloride; It can also be prepared from isomeric hexadienoic acids obtainable by the nickel-catalyzed reaction of acetylene and carbon monoxide. Today, it is commercially and widely produced from crotonaldehyde and flax.

How does Sorbic Acid look?

It is in the form of crystalline powder, white in color.

What is the molecular formula of Sorbic Acid?

Molecular Formula: C6H8HE2

In which sectors is Sorbic Acid used?

  • Preservative in the food industry
  • Production of plasticizers and lubricants

What are the usage areas (processes) of Sorbic Acid?

  • Sorbic acid and its salts such as sodium sorbate, potassium sorbate and calcium sorbate are antimicrobial agents often used as preservatives in foods and beverages to prevent the growth of mold, yeast and fungi. It can be used during the production phase of the food or by spraying it on afterwards. The intensity and form of use should be determined according to the pH value, packaging type and humidity of the environment.
  • Sorbic acid can also be used as an additive for cold rubber and as an intermediate in the manufacture of some plasticizers and lubricants.
