Abstract
This invention is related to methods for inactivating micro-organisms using high pressure processing. A method is described for inactivating micro-organisms in a product using high pressure processing including the steps of packing said product in a flexible container, heating said product to a pre-pressurized temperature, subjecting said product to a pressure at a pressurized temperature for a time period; and reducing the pressure after said time period. The method of the present invention could further comprise an additional step of subjecting said product to a predetermined amount of oxygen for a time interval. The methods of the present invention may be applied preferably to food, cosmetic or pharmaceutical products.
Claims23
A method for inactivating micro-organisms in a product using high pressure processing comprising the steps of:
- a) packing said product in a flexible container;
- b) heating said product to a pre-pressurised temperature;
- c) subjecting said product to a pressure of at least 500 bar at a pressurised temperature for a time period, the pressure being applied to the product through the flexible container, wherein a volume of the flexible container is subject to reduction in response to the applied pressure;
- and
- d) reducing the pressure after said time period.
A method for inactivating micro-organisms in a product using high pressure processing comprising the steps of:
- a) packing said product in a flexible container;
- b) subjecting said product to a pre-determined amount of oxygen for a time interval, said pre-determined amount of oxygen being sufficient to induce oxidation reactions toxic to aerobic as well as anaeorobic microorganisms;
- c) subjecting said product to a pressure of at least 500 bar at a pressurised temperature for a time period, the pressure being applied to the product through the flexible container, wherein a volume of the flexible container is subject to reduction in response to the applied pressure;
- and
- d) reducing the pressure after said time period.
