Abstract
Environmentally friendly processes for prevention of qualitative deterioration and quantitative loss of plant matter and foodstuffs, during all stages of storage and handling, including pre- and post-harvest, pre- and post-planting, distribution and marketing involves the use of H2O2 compositions including Ag and at least one of Cu and Zn ions. The processes can also be used to prevent sprouting and rooting, and to promote fecundity of certain plant matter, and can also be used to eliminate or reduce quantities of harmful organisms and substances from soil, other growth media and substrates, equipment, materials water, workspaces and surfaces.
Claims21
A method of treating edible matter or flower bulbs or tubers, comprising
- contacting said edible matter or flower bulbs or tubers with a hydrogen peroxide solution and adjusting carbon-dioxide-oxygen gas balance about said edible matter or flower bulbs or tubers, wherein
- said hydrogen peroxide solution contains metallic ions of silver and at least one of copper and zinc, said metallic ions being present in an amount of 10 ppb to 5%;
- and contains at least one of peracetic, nitric, sulfuric and phosphoric acid, and optionally at least one of salicylic acid, citric acid and phosphonic acid, and optionally glycerin;
- said solution is applied about said edible matter or flower bulbs or tubers in the form of a dry fog, fumes or smoke, wherein said solution comprises microdroplets having a particle size of 0.001 to 100 microns, and
- said edible matter or flower bulbs or tubers is maintained at a relative humidity of at least 70%,
- with the proviso that said edible matter or tuber are not potatoes.
A method of treating edible matter or flower bulbs or tubers, or equipment, or spaces, or surfaces, comprising
- contacting said edible matter or flower bulbs or tubers, or equipment, or spaces, or surfaces with a hydrogen peroxide solution by spraying said hydrogen peroxide solution onto said edible matter or flower bulbs or tubers, or equipment, or spaces, or surfaces;
- or
- immersing said edible matter, or flower bulbs or tubers, or equipment, or surfaces, into a bath of said hydrogen peroxide solution, wherein
- said hydrogen peroxide solution consisting essentially of (1) aqueous hydrogen peroxide, (2) metallic ions of silver and at least one of copper and zinc, said metallic ions being present in said hydrogen peroxide solution in an amount of 10 ppb to 5%, (3) at least one of peracetic, nitric, sulphuric and phosphoric acid, and optionally (4) one or more of salicylic acid, phosphonic acid, citric acid and glycerin.
