Methods of using a non-irritant, low pH acidic composition to destroy undesirable microorganisms are described. The methods may be used on food products, food processing equipment, and in aqueous solutions.
대표청구항▼
1. A method for destroying microorganisms on a food product, food processing equipment, or in an aqueous solution comprising applying to the food product, food processing equipment, or aqueous solution a composition that is not an irritant, or a dilution thereof, prepared by the steps comprising a)
1. A method for destroying microorganisms on a food product, food processing equipment, or in an aqueous solution comprising applying to the food product, food processing equipment, or aqueous solution a composition that is not an irritant, or a dilution thereof, prepared by the steps comprising a) combining a low pH acid of approximately 98% purity, selected from the group consisting of sulfuric acid, phosphoric acid, fumaric acid and acetic acid, with water and a metal sulfate to provide a mixture;b) heating the mixture of step a) in a pressurized vessel at approximately 15 psi at a temperature between about 250° F. and about 1200° F.c) cooling the mixture of step b);d) adding a stabilizer at about 10 percent of the total weight of the mixture of step c) to the mixture after cooling, wherein the stabilizer comprises the mixture of step a); ande) adding sodium hypochlorite to the mixture. 2. The method of claim 1, wherein the food product is a fruit, flower, leaf, stem, root, seed or other edible part of a plant. 3. The method of claim 1, wherein the food product is a fungus. 4. The method of claim 1, wherein the microorganism is a bacterium, fungus, or virus. 5. The method of claim 1, wherein the metal sulfate is sodium sulfate. 6. The method of claim 1, further comprising adding a metal ion in the form of a metal sulfate to the composition or a dilution thereof. 7. The method of claim 6, wherein the metal sulfate is selected from the group consisting of copper sulfate, silver sulfate, zinc sulfate, magnesium sulfate, and manganese sulfate. 8. The method of claim 1, wherein the aqueous solution is waste water. 9. A method of making a composition, wherein the composition is not an irritant and wherein the composition is capable of destroying microorganisms when the composition is applied to a food or to a food processing equipment or to an aqueous solution and the microorganisms are contacted by the composition, comprising a) reacting an acid of approximately 98% purity, selected from the group consisting of sulfuric acid, phosphoric acid, fumaric acid and acetic acid, with water and at least one metal sulfate at a temperature between about 250° F. and about 1200° F. at a pressure of approximately 15 psi to provide a mixture;b) cooling the mixture to about 70° F. to about 160° F.;c) adding a stabilizer at about 10 percent of the total weight of the mixture of step b) to the mixture after cooling, wherein the stabilizer comprises the mixture of step a); andd) adding sodium hypochlorite to the mixture of step c). 10. The method of claim 9, wherein the at least one metal sulfate is sodium sulfate. 11. The method of claim 9, further comprising adding an additional metal ion in the form of a metal sulfate to the composition or a dilution thereof. 12. The method of claim 9, wherein the metal sulfate is selected from the group consisting of copper sulfate, silver sulfate, zinc sulfate, magnesium sulfate, and manganese sulfate. 13. The method of claim 9, wherein the food product is a fruit, flower, leaf, stem, root, seed or other edible part of a plant. 14. The method of claim 9, wherein the food product is a fungus. 15. The method of claim 9, wherein the microorganism is a bacterium, fungus, or virus.
