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： A deactivation approach for deactivating microorganisms in a high-strength-electric field treatment system (300), can be characterized as an apparatus for reducing microorganism levels in products. The apparatus (300) has an inlet tube (302) of substantially uniform cross-sectional area extending from a distance before a treatment zone to at least into the treatment zone, the treatment zone is located between electrodes (304, 306); a substantially ogival electrode nose (304) positioned in the treatment zone; an outer electrode (306) forming an interior of the inlet tube in the treatment zone. The treatment system (300) can be employed in a method having steps of flowing the product through an inlet tube of substantially uniform cross-sectional area extending from a distance before a treatment zone to at least into the treatment zone; flowing the product between a substantially ogival electrode nose (304) position in the treatment zone, and an outer electrode (306) forming an interior of the inlet tube in the treatment zone; and applying at least one high strength electric field pulse (317) to the product during transit through the treatment zone.
