| A method and device related to a liquid product pressure and (optionally) temperature treatment method reduces the level of microorganisms in the liquid product to a preselected level. Utilizing the method, liquid product is diffused in a chamber with the speed of pressure variation of liquid product in one embodiment of about 109 Pa/sec. The preferred speed of the diffused drops is about 10 m/sec. The liquid product can optionally be heated before or during diffusion, and is preferably heated as a diffused liquid product by mixing it with superheated steam. The device includes a chamber and a diffuser in communication with the chamber. Optionally, the device may include a heating apparatus, such as a steam generator connected via a pressure control valve to a steam super heater, a cooling chamber connected via a pressure control valve with a condenser, a vacuum pump in communication with the chamber, units for condensation and collecting finished products and a vacuum control unit in communication with the chamber. | ||||||

| A method and apparatus for electrically treating foodstuffs flowing through a treatment chamber with low energy, high voltage electrical pulses for non-thermal pasteurization and/or sterilization. Instant-charge-reversal electrical pulses are applied to a foodstuff located between two electrodes in a treatment chamber, each electrical pulse having a pulse width in a range from about 1 to 5 .mu.s with vertically rising voltage to a peak followed immediately with a decreasing voltage through zero volts and continuing to a voltage peak of opposite polarity and rising vertically back to zero volts. The electrical pulses are very low energy (0.1-25 Joules/pulse) and the field strengths are in the range 15 kVolts/cm to 120 kVolts/cm. This instant-charge-reversal electrical pulse is shown to have a much greater microbial killing power compared to other pulse waveforms used to treat foodstuff. The apparatus uses an electrode arrangement including a cylindrical inner electrode and an annular disc with the cylindrical electrode inserted through the hole in the disc. | ||||||

| The method of the invention is characterized in that in the first phase the device installation is filled with processed liquid product, yielding a low pressure zone and then the processed liquid product is introduced under high pressure into the cavitation process, where moving at a rate of not less than 3 m/s and under pressure of not less than 20 bar is introduced to the cavitation and rotation location of the separated streams of the processed liquid product, which rotating in the further part, in the longitudinal axis of the cavitator, move in the opposite directions, resulting in differential pressure leading to cavitation process with effects characteristic for sterilization and homogenization with heterogeneous parameters, wherein in the next phase a separation takes place into a liquid product, which has a particle size larger than 600 nm and a liquid product which has a particle size smaller than 600 nm, wherein the liquid product of larger particle size is directed to cooling and complementary cavitation reprocessing, and the liquid product of smaller particle size is subjected to particle size analysis control, by which the liquid product, which meets the preset parameters, is directed to the finished product acceptance, and the liquid product which does not meet the acceptance criteria is sent to the next reprocessing. The device of the invention is characterized in that it comprises a low pressure pump (2), which is used to fill the device installation with processed liquid product, wherein in a subsequent operation the particle size analyzer (7) switches the high pressure pump (1) on, introducing at a pressure not less than 20 bar the processed liquid product into the cavitator (3), where the cavitation process takes place, the resulting liquid product having a heterogeneous structure is introduced into the separator centrifuge (4), in which takes place, depending on parameters, the separation of the flow into the heat exchanger (5) and the cavitation reprocessing, and the flow through the valve (6) to the particle size analyzer (7), which directs the liquid product to the reception point. | ||||||

| The present invention relates to a treatment method for reducing the bacterial content of a food and/or biological medium of interest containing lipid droplets, which method comprises the following steps: (a) a step of homogenization applied to said medium of interest, (b) a step of microfiltration applied to said homogenized medium of interest resulting from step (a), on a membrane having a cut-off threshold which allows at least some of said lipid droplets to penetrate into the permeate, while at the same time retaining at least some of said bacteria in the retentate, and (c) the recovery of said permeate resulting from step (b), constituting a homogenized food and/or biological medium in which the bacterial content is lower than in the medium before the implementation of said method.

| 50 | METHOD FOR ELIMINATING BACTERIA FROM FOOD | US15189463 | 2016-06-22 | US20160295900A1 | 2016-10-13 | Lex Camany |
| 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. | ||||||
