A method is described for the production of sorbic anhydride, in which alkali metal or alkaline earth metal salts of sorbic acid are reacted with phosgene in an inert organic solvent. In addition, use thereof as a preservative in foods, in particular drinks, is described.

Method for producing sorbic anhydride and also use thereof as a preservative in foods

By using protonic acids, diesters of dicarbonic acid may be stabilized against thermal and chemical decomposition over a relatively long period. Mixtures of diesters of dicarbonic acid and protonic acids are outstandingly suitable for preserving foods.

Stabilization of dicarbonate diesters with protonic acids

By using phosphorus compounds, diesters of dicarbonic acid may be stabilized against thermal and chemical decomposition over a relatively long period. Mixtures of diesters of dicarbonic acid and phosphorus compounds are outstandingly suitable for preserving foods.
