摘要： Microorganisms are deactivated in a food product (10) using an electrode (16) 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 (16). An electrical field results from the deactivating charge having an electric field strength of at least 5.000 volts/cm. Substantially all of the residual charge is removed from the first electrode (16) 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.
摘要翻译：使用与食品电气接触的电极（16）在食品（10）中使微生物失活。电流信号在指定的时间周期内被施加到电极，导致在第一电极（16）上形成去激活电荷。来自具有至少5.000伏特/厘米电场强度的去激活电荷产生电场。基本上所有的剩余电荷在放电期间从第一电极（16）中去除，使得在放电周期之后将大约零净电荷输送到第一电极，从而降低电泳副作用。电流信号使电极处的双电层充电到规定的电压。一个实施方案中，规定的电压不超过规定的反应物质的反应电压超过规定的阈值时间，从而减少食品内的电化学反应。

摘要： A vacuum-sealable hatch (130) that is vacuum sealed to a surface of a passthrough light sterilization device (102), and related methods of use, consists of a hatch body (132) having at least a portion adapted to fit within an opening of the treatment chamber (138) and a flexible piece (136) attached to the hatch body. The flexible piece extends peripherally from the hatch body and includes a seating portion which is adapted to be vacuum sealed to a seating region of an interior surface of the treatment chamber. The hatch body (132) and the flexible piece (136) seal the treatment chamber (138) from the outside environment, thereby preventing the free flow of microorganisms to and from the treatment chamber and the outside environment. In some variations, at least the seating portion of the flexible piece is transmissive to the light treatment such that surfaces underneath the seating region are treated by the light treatment.

摘要： A method of deactivating microorganisms in food products, packaging material, water, air, and other products involves illuminating the microorganisms using at least one short-duration, high-intensity pulse of broad-spectrum polychromatic light. In variations of this embodiment, the light has an intensity of at least 0.1 J/cm , the pulse duration is from between about 10 nanoseconds and 10 milliseconds, and/or at least 50 % of the at least one pulse's energy is transmitted in light having wavelength from between about 170 and 2600 nanometers. Advantageously, the microorganisms may be Cryptosporidium parvum oocysts, Bacillus pumilus spores or poliovirus.

摘要： Methods and apparatuses are described for food product preservation by deactivation of microorganisms and enzymes by applying high-intensity, short-duration pulses of polychromatic light in a broad spectrum to packaging material surfaces. In some embodiments, a photodiode is employed for detecting the intensity of the light, and a control circuit is used to adjust power delivered to a flashlamp if the intensity of the light needs adjustment. In some embodiments, an outer safety glass is employed to protect the flashlamps. The outer safety glass may include coating materials at ends thereof. In addition, several variations of lamp assembly geometries accommodate small diameter packaging material tubes by, for example, using a fill pipe having offset first and second portions with a transitional region thereinbetween, or be eliminating the water jackets and using an outer safety glass to contain water as it is passed over flashlamps. In another additional embodiment, a lamp holding device includes a holding cylinder with a first flange, which, together with a compression cylinder, compresses the first O-ring into the flashlamp. In yet another embodiment, a lamp holding device is positioned in a receptacle into which an electrode of a U-lamp is inserted. The lamp holding device allows a proximal portion to move relative to a distal portion thereof. In yet a further embodiment, a light guide is positioned to receive light emitted from a linear flashlamp and to transmit such light into a packaging material cup.

摘要： The present invention is directed to methods and apparatuses for preserving fluid foodstuffs. More particularly, it is directed to methods and apparatuses for extending the shelf life of perishable fluid foodstuffs such as dairy products, fruit juices and liquid egg products, which contain significant levels of microorganisms. The improved methods and apparatuses incorporate a plurality of electric field treatment zones (106) with cooling units (108) between each pair of treatment zones in order to maintain the temperature of the pumpable foodstuff at a level at which microorganisms are killed in sufficient numbers and at which changes in the flavor, appearance, odor, or functionality of the foodstuff remain within acceptable ranges. For a comparable microorganism kill, foodstuffs prepared by the present process have significantly higher quality than foodstuffs prepared with standard thermal processes (e.g., ultra-high temperature pasteurization).
