Disclosed is technology to solve the problem in a world that is inundated with microbes of keeping food fresher for longer and shelf-life extension to enhance food security and safety without refrigeration/freezing, chemical preservatives integrated into the food product and/or physically/chemically altering the food product. Aspects of the technology are directed at the three levels of the food delivery system; namely, supermarket style display ware, bulk packaging and overseas container. This technological problem is solved by situating on food contacting/abutting surfaces of display ware, bulk packaging and oversees containers an antimicrobe agent formulated as a composition comprised of (i) between about 0.25% (w/w) to about 0.75% (w/w) benzalkonium chloride; (ii) between about 0.02% (w/w) to about 1.00% (w/w) of a kill agent selected from the group consisting of hydrogen peroxide and phenoxyethanol; (iii) between about 0.25% (w/w) to about 0.75% (w/w) 3-(tri-methoxysilyl)propyldimethyl octadecyl ammonium chloride and (iv) between about 97.50% (w/w) to about 99.48% deionized water.

A wearable disinfecting device includes a skin-protective glove and a disinfecting material. The disinfecting material is attached to the external surface on the palm side of the skin-protective glove. The disinfecting material includes an absorbent material that is at least partially saturated with a disinfecting liquid. The skin-protective glove is chemically resistant to the disinfecting liquid. A protective film that covers the disinfecting material can be releasably attached to the external surface of the skin-protective glove.

A free radical sterilization system having a chamber defining a region, and a generator for generating free radical reach effluent from a free radical electric generator and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the electric generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The free-radical sterilization system is used in sterilizing items in the chamber and, with an open-bottomed wound chamber, in treating wounds on a body.

A scrubbing assembly for treating malodorous air by chemical scrubbing one or more chemical components from an influent airflow, particularly one or more chemical components that have become airborne from chemical intervention solutions used during food processing, such as vapors from peroxycarboxylic acid solutions used during food processing. The peroxycarboxylic acid vapors are removed from air in a continuous manner within the scrubber assembly utilizing a neutralizing chemical solution to provide a treated effluent airflow that can be returned back to the point of use area from which the malodorous air was removed for treatment.

To sterilize a sterilization filter unit with heated steam, minimize the heat load on the sterilization filter unit and extend the service life of the sterilization filter unit. Heated steam is supplied to a sterilization filter unit that sterilizes supplied air, the temperature of the heated steam discharged from the sterilization filter unit is measured at predetermined time intervals, the F value is calculated from the measured temperature, and sterilization of the sterilization filter unit is ended when the F value reaches a target value.

A disinfection compartment comprising a plurality of wheels; a casing disposed on the disinfection compartment, at least one tank configured to hold antimicrobial solution or hydrogen peroxide solution, a nozzle/dispenser disposed on the casing, and an attachment member configured to provide a detachably secure attachment to a moving unit, wherein the nozzle/dispenser is an electrostatic sprayer or electrostatic gun.

Systems and methods for using solid high-level disinfection chemistries to producing disinfectant solutions. In an embodiment, an apparatus comprises: a first container and a second container. The first container is configured to receive water, sodium percarbonate and tetraacetylethylenediamine. The water, the sodium percarbonate, the tetraacetylethylenediamine react within the first container to produce a mixture comprising peroxyacetic acid. The second container is in fluid communication with the first container, wherein the second container is configured to receive an acid and the mixture. The mixture and the acid mix in the second container to produce a disinfectant solution having a pH between 5.0 and 7.0.

An indicator and method of use thereof, and indicator system and method of use thereof are provided to determine the degree of an oxidative treatment. An indicator is incorporated into the oxidative treatment. The object and the indicator are subjected to the oxidative treatment. A discoloration of the indicator occurs based on an oxidation of the polymer by a process condition of the oxidative treatment oxidizing the polymer. The discoloration of the indicator is measured against a threshold color value to determine the degree of the oxidative treatment.

A biofilm mitigation apparatus includes a supply container, a disinfectant generator, a power source, and a delivery tube. The supply container is configured to store one or more materials for a formation of a disinfectant. The disinfectant generator is configured to generate the disinfectant from the one or more materials from the supply container. The power source is configured to provide electrical power to the disinfectant generator. The delivery tube is configured to transport the disinfectant from the disinfectant generator to a biofilm.

The invention relates to a disinfection process comprising the feed materials H.sub.2O.sub.2 and NO.sub.2.sup.− and a mixing step and a distribution step, wherein the mixing step and the distribution step (during which each point on the surface being disinfected is wetted with a solution of active substance) are implemented during a processing period Z.sub.A. An exposure step follows, in which the distributed solution of active substance acts upon the surface in contact with the solution of active substance during an exposure period Z.sub.E. In this process, the maximum NO.sub.2.sup.− concentration during the mixing step is of 300 mM, and the time-integrated reaction rate W is represented during the exposure period Z.sub.E by the integral formula (I), where k.sub.1 denotes the pH-value-dependent speed constant of the reaction between H.sub.2O.sub.2 and NO.sub.2.sup.− and the pH value of the solution of active substance before it contacts the surface being disinfected lies in the range of 2.1≤pH≤6.8. The invention also relates to a device for providing the solution of active substance.
