摘要： Flashlamp system for sterilising microorganisms comprises a flashlamp (104) for generating high-intensity, short-duration pulses of polychromatic light in a broad spectrum. The light pulses are directed at the target object to deactivate the microorganisms. A photosensitive detector (102) receives a portion of each of the pulses as a measure of the amount of light illuminating the target object to generate an output signal. A control system (106), coupled to the flashlamp system and photo-sensitive detector, determines in response to the output signal whether the pulses of light are sufficient to cause a prescribed level of deactivation of microorganisms in the target object.

摘要： 2057031 9015547 PCTABS00002 A pulsed field treatment apparatus for applying pulsed electric fields to pumpable foodstuffs has an electric field treatment chamber (108) with a first electrode (302) and a second electrode (308). A solid dielectric separator (318) having a dielectric nonconductive spacer separates the first electrode (302) from the second electrode (308) externally of the chamber and has a minimum surface pathway length between the first electrode (302) and the second electrode (308) of at least twice the minimum distance between the first electrode and the second electrode within the chamber. An inlet conduit (304) is connected to the chamber for introducing pumpable foodstuffs and an outlet conduit (306) is also connected to the chamber for discharing pumpable foodstuffs which have passed through the electric field treatment chamber. A high voltage pulser (112) generates electric pulses at the rate of at least 0.01 pulses per second to the first and second electrodes (302, 308) which are excited by the electrical pulses and produce an electric field having an electric field strength of at least 25,000 volts per centimeter. A pump connected to the inlet conduit forces the pumpable foodstuff through the electric field treatment chamber at a rate such that all of the pumpable foodstuff is subjected to at least one electric field pulse during its transit through the electric field treatment chamber.

摘要： Microorganisms are deactivated in a food product using an electrode placed into electrical contact with the food product. A current signal is applied to the electrode during a specified time period, causing a deactivating charge to build up on the first electrode. An electrical field results from the deactivating charge having an electric field strength of at least 5,000 volts/cm. Substantially all of a residual charge is removed from the first electrode during a discharge period, such that an approximately zero net charge is delivered to the first electrode following the discharge period, thereby reducing electrophoretic side-effects. The current signal causes an electrical double layer at the electrode to charge to a prescribed voltage. One embodiment, the prescribed voltage does not exceed a reaction voltage of a prescribed reacting material species for more than a prescribed threshold period, thereby reducing electrochemical reactions within the food product.

摘要： An improved method and apparatus for deactivating contaminants in one embodiment involves a pulsed light treatment system (40) for illuminating one portion of the contaminants with light (28) having frequencies within a first prescribed frequency range, resulting in the deactivating of the one portion of the contaminants, and illuminating another portion of the contaminants with light (28'') having frequencies within a second prescribed frequency range, the other portion being at a titanium dioxide supplemented surface (35), so as to initiate the release of a highly reactive agent in a reaction in which titanium dioxide serves as a catalyst. The highly reactive agent deactivates the other portion of the contaminants.

摘要： An improved method and apparatus for deactivating organisms on the surface of a perishable food product, or on the surface of a packaging material includes, in one embodiment, a heating device (700, 704) for heating a surface of the food product or packaging material to a prescribed temperature, and a flashlamp system (30) for illuminating the surface of the food product or packaging material with light (28) having frequencies within a prescribed frequency range. At least a portion of the light with which the food product or packaging material is illuminated deactivates organisms substantially at the surface of the food product or packaging material. In another embodiment, the method includes applying a chemical agent to the surface of the food product or packaging material, instead of or in addition to the heating of the food product or packaging material. A further embodiment employs modified atmosphere packaging in combination with illumination of a food product contained therein.
