| Abstract | The present invention relates to the field of citrus fruit and, more particularly, to a disinfectant composition and process of using the composition for reducing
organisms on citrus fruit and on equipment used with citrus.
A disinfectant composition is disclosed effective against a pathovar of pathogenic for citrus, comprising an aqueous solution of a carboxylic acid, hydrogen peroxide, and a percarboxylic acid product thereof. In a preferred composition the percarboxylic acid comprises peroxyacetic acid in an equilibrium aqueous solution with hydrogen peroxide, and acetic acid. The composition is used in a process to disinfect citrus fruit and equipment used therewith by contacting with a sufficient concentration of the composition for a sufficient time for reducing the organisms by at least 99.9%. |
