The present disclosure is directed to antimicrobial compositions comprising a hypochlorite salt, a copper (II) salt, and an optionally acid that is an inorganic acid, an organic acid, or a combination thereof, and optionally a buffering agent, and having a chlorine concentration of between 0.1 ppm and 300 ppm and a copper (II) concentration of between 0.1 ppm and 300 ppm. Methods of making and using these compositions is also described.

Disclosed in certain embodiments are systems and methods for prolonging the shelf life of produce. The following presents a simplified summary of various aspects of the present disclosure in order to provide a basic understanding of such aspects. This summary is not an extensive overview of the disclosure. It is intended to neither identify key or critical elements of the disclosure, nor delineate any scope of the particular embodiments of the disclosure or any scope of the claims. Its sole purpose is to present some concepts of the disclosure in a simplified form as a prelude to the more detailed description that is presented later.

The system for cleaning fresh and freshly-cut produce is designed to clean produce as soon as practicable after the produce is cut. As the produce falls downwardly, a spray manifold directs a produce-washing liquid upwardly so that the produce-washing liquid directly sprays and impacts the falling produce. The impact of the produce-washing liquid causes the produce to tumble and the descent of the produce is slowed, and consequently the produce is thoroughly coated and cleaned by the produce-washing liquid. In an alternative embodiment, a suspending fluid (preferably air) is simultaneously directed to the falling produce to slow the descent of the produce and further ensure that the produce is thoroughly washed and directly sprayed by the produce-washing liquid.

The present invention provides a stabilized hypohalous acid solution (or formulation thereof), which may be conveniently packaged for sale, or stored for later use on demand. The invention further provides methods of making the stabilized hypohalous acid solution, as well as methods of use for disinfecting mammalian tissue, including wounds and burns, disinfecting or cleansing surfaces, or treating and/or preserving food products and cut flowers, among other uses.

A new antimicrobial wash for treating fresh fruits and vegetables to reduce microorganisms, especially human pathogens, comprises an aqueous solution of hydrogen peroxide and one or more fruit acids.
