Disinfecting devices and related methods are provided that apply germicidal ultraviolet light to disinfect dispensing components of food and beverage dispensers. A disinfecting holster for a bar gun includes a support surface configured to interface with a bar gun to support the bar gun when stowed in the holster, a housing coupled with the support surface and surrounding a dispensing nozzle of the bar gun when the bar gun is stowed in the holster, and an ultraviolet light source configured to emit germicidal ultraviolet light onto the nozzle. The housing substantially contains the ultraviolet light within the housing during the application of the ultraviolet light to the dispensing nozzle. The ultraviolet light can be periodically applied to maintain the nozzle in a disinfected state.

Electrochemical processes and systems for preserving perishable food are described. The process and system allow for the preservation of perishable food in the presence of water moisture, melanin, or a precursor, derivative, analog, or variant of melanin, and electromagnetic energy, such as visible or invisible light energy. There exists a need in the art for improved methods and processes for preserving perishable foods that overcome certain disadvantages associated with known methods for preserving perishable food, such as addition of preservatives, refrigeration/freezing, drying/dehydration of food, and storage under vacuum. The invention satisfies this need by providing a process and system for preserving perishable food in the presence of water moisture, electromagnetic energy, and melanin, melanin precursors, melanin derivatives, melanin analogs, or melanin variants.

The present invention relates to an apparatus (100) for the inspection and selection of food products contaminated by aflatoxins, in particular dried fruit, comprising a conveyor line (90), a first inspection station (20) with at least one ultraviolet light source (23a, 23b) and an RGB video camera (24) mounted in a housing (21), a first control unit, configured to analyse the images of the video camera to identify products with photoemissions compatible with that of aflatoxins, and a first selection unit (30), placed downstream of the first inspection unit (20), where said selection unit (30) is controlled by the first control unit and is configured to separate the uncontaminated food products from those potentially contaminated and to eject the former toward a collection point.

A freshness preservation method for fruits and vegetables includes irradiating fruits or vegetables within 24 hours after harvest with light having a peak wavelength in a range from 256 nm to 297 nm, thereby extending, by equal to or greater than 25% compared to when the fruits or the vegetables are not irradiated by the light, time for preserving equal to or greater than 95% of a weight of the fruits or the vegetables before light irradiation.

Methods and apparatus are provided for ultraviolet (UV) fluid purification, wherein the fluid is in a gaseous, liquid or solid form or combination thereof, comprising UV-C LED modules having improved light extraction efficiency. UV-C LED(s) are in optical communication with one or more UV-C transmissive window elements.

An xenon lamp power supply, a purification device, and a refrigeration device are provided. The xenon lamp power supply comprises: an input circuit, a coupling assembly, an output circuit, and a control circuit. The input circuit comprises an alternating-current input end and a direct-current output end, and the input circuit is used for converting alternating current input by the alternating-current input end into direct current output by the direct-current output end. A first end of the coupling assembly is connected to the direct-current output end. The output circuit comprises a xenon lamp power supply circuit, and the xenon lamp power supply circuit is connected to a second end of the coupling assembly, so as to convert electric energy from the second end into direct-current power, and then supply power to a xenon lamp.
