General description

Sorbic acid is an organic acid. It is weakly acidic in nature. Its permeability through an edible film made of methylcellulose and palmitic acid has been evaluated.

Application

Sorbic acid may be employed as a starting reagent for the synthesis of p-toluic acid and alkyl-p-toluates.
