Abstract: A food treatment method involves applying alkali metal bisulfate to an outer surface of a food, by an application process beginning with the alkali metal bisulfate in a solution and ending with the alkali metal bisulfate at least partially crystallized when it contacts the food surface. In certain embodiments, the application process causes at least partial evaporation of solvent from the solution. For example, the application process may include forming droplets of the solution, and/or propelling the solution with a gas having a relative humidity not greater than 60% or a temperature of at least 20° C. In certain embodiments, the beginning solution is an aqueous solution including the alkali metal bisulfate at a concentration within a range from 30% to 80%.

Abstract: An antimicrobial composition useful for microbial reduction on food includes an oxidizer and an acid component. The oxidizer includes hydrogen peroxide and/or peroxyacetic acid.

Abstract: A foot liquid dispenser has a liquid reservoir on a base. A liquid sprayer on the base is connected to the reservoir and is mounted to discharge at a predetermined height above the base and in a predetermined direction. The sprayer is operated by a lever actuated by a bail pivoted on the base and having a small transverse bar projecting beyond the base and engageable by the user's foot. The bar is pivoted to travel from an upper position substantially above the spray then through the spray to a lower position substantially below the spray so the user's foot in depressing the bar is sprayed both bottom and top and excess liquid falls free of the dispenser.
