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.
