System and method for treating liquid beverage using electromagnetic field comprising ac and dc components

A system for treating a liquid beverage using an electromagnetic field comprising alternating current (AC) and direct current (DC) components, comprising:

• a device for generating a DC biased time-varying frequency pulsating electromagnetic wave comprising a biased DC component,
• a power supply for supplying power to the device,
• a treatment chamber containing a treatment liquid beverage in either static or flowing state,
• one or more capacitive emitter pairs arranged in a predetermined pattern and placed to be in direct contact with the treatment liquid beverage, wherein each two adjacent capacitive emitters are spaced at a predefined distance and respectively electrically coupled with first and second output terminals of the device,
• wherein the device is configured to apply the DC biased time-varying frequency pulsating electromagnetic wave to the treatment liquid beverage to generate a pulsating capacitive field having a field strength between the capacitive emitters, and
• wherein a time-varying frequency and pulsating AC wave current comprising the biased DC component is provided in the treatment liquid beverage to produce a negative oxidation reduction potential (ORP) shift in the treatment liquid beverage whose pH substantially remains constant under a combined effect of the field strength of the pulsating capacitive field and the biased DC component.
