Abstract
This present invention generally relates to a process for manipulating the chemistry of a product using high voltage atmospheric cold plasma (HVACP) in the presence of a working gas, and in particular to a process for inactivating pathogenic microorganisms in a liquid product by adding an acidic component to or adjusting an acidic component of a product in combination with HVACP treatment. A product of this process is also in the scope of this disclosure.
Claims28
A process for manipulating a product using high voltage atmospheric cold plasma (HVACP), comprising the steps of:
- a. adding an acidic component to or adjusting an acidic component of a product to a final concentration from about 10 ppm to about 50,000 ppm;
- b. setting up a defined compartment filled with a working gas and an electric system for generating atmospheric cold plasma (ACP);
- c. generating ACP by applying a high electric voltage through a controller;
- and
- d. Exposing said product to said ACP in said defined compartment.
(canceled)
A product prepared using high voltage atmospheric cold plasma (HVACP), according the process of:
- a. adding an acidic component to or adjusting an acidic component of a product to a final concentration from about 10 ppm to about 50,000 ppm;
- b. setting up a defined compartment filled with a working gas and an electric system for generating atmospheric cold plasma (ACP);
- c. generating ACP by applying a high electric voltage through a controller;
- and
- d. Exposing said product to said ACP in said defined compartment.
26-35. (canceled)
A system for inactivating pathogenic microorganism in a liquid product with using high voltage atmospheric cold plasma (HVACP) comprising a controller, a high voltage transformer and a controller, a defined compartment for housing electrodes connected to said high voltage transformer and controller, a working gas, and said liquid product for HVACP treatment.
