A contact interfacing conductive receptacle is provided. The contact interfacing conductive receptacle includes a housing sized to receive an object including water. The housing includes one or more non-transfer material pieces and two or more transfer material pieces. Each transfer material piece is configured to provide conductivity and provides a field to a different portion of the object. The transfer material pieces are integrated with the non-transfer material pieces.

The present invention discloses a method to eliminate gram negative bacterial pathogens from food or produce. This method includes the steps of exposing produce or food to an electrically conductive medium having an anode and a cathode; inserting the anode of the electrically conductive medium into a water flume; connecting the cathode of the electrically conductive medium to a conveyor belt to convey the produce or food through the water flume for increasing the negative electrostatic charge on the surface of the pathogen cells selected to cause cell lysis; and attaching one or more misters to the roof of a water chamber to disperse the water in the water chamber. When DC current is applied to any pathogen cell that is gram negative, it overrides the internal governing electrostatic charge controlling the pathogen cell causing cell lysis. This is the “Achilles heel” of gram negative bacteria pathogen cells.

A package for fruits and vegetables having galvanic functionality is formed by using two or more metals with different galvanic activity properties on the surface of a nonmetallic substrate. The metals may be deposited electrolytically, by vacuum, autocatalytically, or by other methods. The metals are selected to create a galvanic reaction after the package is filled with a low pH food product and its associated liquids, juices, brine, etc. The package may extend the shelf-life of the food product contained therein, for example, by making metal ions available to the food product.

The present invention discloses a system and a method to eliminate E. Coli bacteria from various food products. When DC current is applied to any pathogen that is gram negative, it overrides the internal governing electrostatic charge that controls and causes the hydrophilic nature of E. Coli to be activated and rushes in water instantaneously. This results in E. Coli blowing itself up. This is E. Coli's “Achilles heel”. Testing has shown when E. Coli is exposed to as little as 30 volts for approximately 30 seconds, 99.9% of ALL E. Coli were killed. 100% kill using 60 volts has been achieved through this invention.

An object of the present invention is to provide a preservation treatment apparatus which can sufficiently apply an effect generated by charges to an object to be preserved thus more surely exhibiting a preservation effect generated by charges, and can stably hold an effect of a potential applied to the object to be preserved by controlling the flow of an electric current in a stacked portion of the object. A preservation treatment apparatus includes: a conductive enclosure structure arranged at least either one of both sides or an upper side of the placing portion 1, and surrounding at least either one of both sides or the upper side of the object O as viewed from the object O placed on the placing surface; a first electrode 21 brought into contact with an upper position of the placing portion 1 close to one side portion 11S of the placing portion 1; a second electrode 22 brought into contact with a lower position of the placing portion 1 close to the other side portion 12S of the placing portion 1; a third electrode 23 brought into contact with a position of the enclosure structure close to one side portion of the enclosure structure; a fourth electrode 24 brought into contact with a position of the enclosure structure close to the other side portion of the enclosure structure; and a voltage supply portion 20 which is electrically connected with these electrodes respectively. The voltage supply portion 20 simultaneously applies a negative DC voltage to either one of the first electrode 21 and the second electrode 22 and applies an AC voltage to the other one of the first electrode 21 and the second electrode 22.

The invention relates to a method for prolonging the shelf life of agricultural and food products placed in a large storage room having a volume greater than 200 m3, wherein said method comprises treating the air in said storage room by means of withdrawing air from the storage room, passing the air through a gas-liquid contactor, circulating an electrolyzed halide solution through said gas-liquid contactor, directing the treated air back into the storage room, wherein an acid is intermittently added to said circulated halide solution. An apparatus suitable for carrying out the method is also provided.

A CO-containing modified atmosphere packaging (MAP) gas is generated from a processing gas including CO2 and an optional inert gas by applying an electric field under conditions sufficient to generate non-thermal plasma. The fresh appearance of meat or seafood is maintained for a longer time by storing them in a container with the MAP gas.
