ABSTRACT:
A frozen chlorine dioxide-containing composition comprising a metal chlorite and a protic acid in a frozen aqueous matrix made by freezing a substantially chlorine dioxide-free aqueous solution comprising a metal chlorite at a concentration ranging from about 0.0005% to about 0.5% by weight and a protic acid at a concentration sufficient to lower the pH of the aqueous solution to a value of about 1.8 to about 5.0. The frozen chlorine dioxide-containing composition has a chlorine dioxide concentration of more than about 3 ppm, while the aqueous solution prior to freezing has a chlorine dioxide concentration less than about 3 ppm. The frozen chlorine dioxide-containing composition is used to disinfect substrates by contacting the same with the frozen chlorine dioxide-containing composition. Suitable substrates include food intended for human or animal consumption, such as meat, fish and poultry.
