Abstract
The present invention relates to novel sulfoperoxycarboxylic acid compounds, and methods for making and using them. The sulfoperoxycarboxylic compounds of the invention are storage stable, water soluble and have low to no odor. Further, the compounds of the present invention can be formed from non-petroleum based renewable materials. The compounds of the present invention can be used as antimicrobials, and bleaching agents. The compounds of the present invention are also suitable for use as coupling agents.
Claims21
1-85. (canceled)
86:
- A method of reducing a population of a microorganism on a food processing surface, the method comprising:
- contacting the food processing surface with a composition comprising a sulfoperoxycarboxylic acid for a sufficient time to reduce the population of the microorganism on the food processing surface;
- wherein the sulfoperoxycarboxylic acid is one or more of the following:
- or a salt thereof.
1 more element
87:
- The method of claim 86, wherein the food processing surface is a surface of a tool, machine, equipment, structure, or building that is employed as part of a food processing activity.
88:
- The method of claim 86, wherein the food processing surface comprises preparation equipment.
89:
- The method of claim 88, wherein the preparation equipment comprises slicing, canning, or transport equipment.
90:
- The method of claim 86, wherein the food processing surface comprises one or more food processing wares.
91:
- The method of claim 90, wherein the one or more food processing wares comprise a utensil, dishware, wash ware, or bar glass.
92:
- The method of claim 86, wherein the food processing surface is a floor, wall, or fixture in which food processing occurs.
93:
- The method of claim 86, wherein the food processing surface comprises aseptic packaging.
94:
- The method of claim 93, wherein the aseptic packaging comprises cold or hot aseptic packaging.
95:
- The method of claim 86, wherein the food processing surface comprises one or more food packaging materials.
96:
- The method of claim 86, wherein the food processing surface is in a food processing facility.
97:
- The method of claim 96, wherein the food processing facility is one or more of a milk line dairy, a continuous brewing system, a pumpable food system, or a combination thereof.
98:
- The method of claim 96, wherein the food processing surface is water from a food processing facility.
99:
- An antimicrobial composition for reducing a population of a microorganism on a food processing surface comprising:
- a composition comprising a sulfoperoxycarboxylic acid, wherein the sulfoperoxycarboxylic acid is one or more of the following:
- or a salt thereof;
- and
- b) optionally, one or more additional functional ingredients.
2 more elements
100:
- The composition of claim 99, wherein the sulfoperoxycarboxylic acid is present in a concentration of at least about 50 ppm.
101:
- The composition of claim 99, wherein the sulfoperoxycarboxylic acid is present in a concentration of between about 0.001 wt-% to about 1 wt-%.
102:
- The composition of claim 99, wherein the composition provides an at least 1 log10 reduction in the population of the microorganism in 30 seconds.
103:
- The composition of claim 99, wherein the composition provides a 5 log10 reduction in the population of the microorganism in 30 seconds.
104:
- The composition of claim 99, wherein the one more additional functional ingredients comprises a chelating agent, sequestrant, buffer, acidulant, detergent, wetting agent, defoaming agent, thickener, foaming agent, solidification agent, colorant, odorant, perfume, cleaning agent, carrier, or a combination thereof.
105:
- The composition of claim 99, wherein the food processing surface is a surface of a tool, machine, equipment, structure, or building that is employed as part of a food processing activity;
- preparation equipment;
- food processing ware;
- floor, wall, or fixture in which food processing occurs;
- aseptic packaging;
- a food packaging material, or a combination thereof.
