A frozen chlorine dioxide-containing composition comprising a metal chlorite and a protic acid in a frozen aqueous matrix made by freezing a substantially chloride 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 5Ø 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.
La présente invention concerne une composition congelée contenant du dioxyde de chlore comprenant un chlorite métallique et un acide protique dans une matrice aqueuse gelée. On obtient cette composition en congelant une solution aqueuse, pratiquement sans dioxyde de chlore, contenant un chlorite métallique à une concentration comprise entre environ 0,0005 % et environ 0,5 % en poids et un acide protique à une concentration suffisante afin de faire baisser le pH de la solution aqueuse à une valeur comprise entre environ 1,8 et environ 5,0. La composition congelée contient du dioxyde de chlore à une concentration supérieure à environ 3 ppm, alors que la teneur de la solution en dioxyde de chlore avant congélation est inférieure à environ 3 ppm. Cette solution congelée contenant du dioxyde de chlore est utilisée en désinfection de substrats par contact de ces substrats avec la composition congelée. Les substrats sur lesquels on peut appliquer cette composition comprennent des aliments destinés à l'homme ou à l'animal, tels que viande, poisson et volaille.
