Sorbic acid was discovered in 1859 by reacting rowanberry oil (from the juice of unripe rowanberry) with strong alkalis. Sorbic acid has antimicrobial effect. Alkali sorbates have good solubility in water. Potassium sorbate can be made into solutions of more than 50% in cold water. Potassium sorbate is the salt of Sorbic acid that is mainly used in food preservations. As an aliphatic carboxytic acid, Sorbic acid is utilized in human and animal bodies like any other fatty acid.
