  • Patent number: 8663722
    Abstract: The present disclosure relates to a process for removal of pesticide residues from aqueous solutions and food products by ionizing radiation. Standard pesticides concentrations recognized by international organizations as maximum residues limit (MRLs) were used as the targeted concentrations in both aqueous solutions and food products. Commercially known pesticides and recommended irradiation doses by International Atomic Energy Agency (IAEA) were selected for this investigation. Aqueous solutions and food products fortified with pesticide residues were subjected to selected doses of ionizing radiation. Radiation-induced removal of pesticide residues is generally greater in aqueous solutions than in food products. Ionizing radiation can reduce the residues of pirimiphos-methyl in potatoes, grapes and dates; malathion and cypermethrin in grapes to below MRLs at the recommended irradiation doses.

  • Publication number: 20130022720
    Abstract: Methods for treating fruits and/or vegetables to oxide any organic contaminates thereon are provided, using an aqueous solution. The aqueous solution can include a ferrous salt and an acid, and can be exposed to oxygen gas, allowing the organic contaminates to be oxidized via exposure to the aqueous solution and oxygen gas. Then, the outer surface of the fruits and/or vegetables can be washed to remove the aqueous solution. The aqueous solution can have a pH of about 4 to about 9, and can also be adjusted during the method. Methods are also disclosed for oxidizing organic compounds in an aqueous sample via measuring the pH of the aqueous sample; determining an appropriate chemical equation for oxidation based upon the pH measured; and thereafter, adjusting the pH of the aqueous sample.

  • Patent number: 6537600
    Abstract: Mobile systems for cleaning and drying produce in order to extend shelf life, are described. Produce cleaning systems (20) are provided that employ plural forms of energy in an ionic liquid-based washing system (22, 24, 26) containing solvents and solutes which promote the conduction of electrical energy. The electrical energy can be applied to the produce in the wash bath (24) in various waveforms, such as a modulating wave superimposed on a carrier wave. Additionally, ultrasonic energy is employed to provide high-frequency mechanical pressure waves against the produce. The electrical energy and the mechanical energy combine to produce energy in the applicable resonant frequency range that acts to destroy or transform pathogens, dirt and synthetic molecules that may exist on the item of produce (190). Systems for drying the item of produce (190), after it has been immersed in a natural soluteladen slurry maintained at a temperature below the freezing point of water, are also provided.
