The invention provides a method for removal of antibiotic residues from food products by irradiating the food product with a dose of ionizing gamma radiation for an effective duration of time. The food product undergoing irradiation by ionizing gamma radiation is selected from a group of dairy and poultry products and its likes thereof.

The present invention relates to the production of a food product, in particular a snack product. In order to distribute additives evenly in a food product, in particular in a snack product, and to obtain a more homogeneous product quality, the method according to the invention comprises the steps of: conditioning the food product by applying an electric field; introducing an additive into the food product; and preserving the food product after the additive has been introduced.

Devices, methods, and systems for disinfection with light are disclosed. In some examples, a lighting source is operable to provide light at wavelength range of about 380 nm-420 nm with an irradiance and/or dosage sufficient for disinfection. One or more sensors and a control system may be used to control operation of the lighting source, such as by adjusting the lighting source in response to various inputs.

A method and a system for producing a change in a medium. The method places in a vicinity of the medium an energy modulation agent. The method applies an initiation energy to the medium. The initiation energy interacts with the energy modulation agent to directly or indirectly produce the change in the medium. The energy modulation agent has a normal predominant emission of radiation in a first wavelength range outside of a second wavelength range (WR2) known to produce the change, but under exposure to the applied initiation energy produces the change. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the energy modulation agent.

A pathogen and pest exterminating device that can efficiently exterminate pathogens and pests in a shorter time. One electrode includes a part to be inserted into a reaction vessel, and other electrode is arranged in a position that opposes the insertion part. A water supply unit is provided to supply water to the reaction vessel through the insertion part, and a gas supply unit provided of supplying gas, which will become plasma, to the reaction vessel. A power supply unit is provided to be capable of applying voltage between the insertion part and the other electrode such that OH radicals are generated inside the reaction vessel to which the water and the gas are supplied. The insertion part is formed in a shape that restricts, between itself and the other electrode, a flow rate of water from the water supply unit such as a coil, waveform, or mesh shape.

The present invention relates to a method and a device for ship-borne freezing of marine products after treated by highly activated water and nondestructive sensing of ice crystals. Through treating the seawater with atmospheric plasma in a certain atmosphere and introducing the tail gas from plasma reactor into the seawater in tail gas collecting device, the highly activated water is obtained. After cooling by the ship-borne refrigeration system, the cooled highly activated water can be used to cool and sterilize the captured marine products timely. During the following freezing processes, both the ultra-high frequency (UHF) electromagnetic field system and pulsed ultrasonic monitoring system are applied simultaneously, which can not only effectively reduce the size of ice crystals and the juice loss of the frozen products during thawing, but also inhibits the thermal effect of electromagnetic field.

The present invention is directed to a system and method for photoeradication of microorganisms from a target. A light source is configured to irradiate the target with purple or blue light in a pulsed mode of irradiation at an average irradiance that preferably ranges from 0.1 mW/cm.sup.2 to 20 mW/cm.sup.2. An electronic circuit is configured to control the light source in accordance with an irradiation schedule that includes a plurality of irradiation sessions. The light source is controlled to provide the purple or blue light at a radiant exposure that preferably ranges from 0.5 J/cm.sup.2 to 60 J/cm.sup.2 during each of the irradiation sessions. The irradiation sessions are provided at a plurality of time intervals so as to cause photoeradication of all or a portion of the microorganisms.
