Non-Thermal Preservation

D Non-Thermal Preservation Definition Involves manipulating the properties of food or its environment without using heat. Examples include: Irradiation Ohmic heating Ozonation High pressure processing

D Non-Thermal Preservation Irradiation Exposure of food to ionizing radiation for preservation In the U.S. irradiated foods are required to be labeled.

D Non-Thermal Preservation Ohmic Heating Food is subjected to an alternating current flow between two electrodes.

D Non-Thermal Preservation Ozonation Water treatment process used to destroy microorganisms by ozone, a gas produced by exposure of oxygen molecules to high electric voltage

D Non-Thermal Preservation High Pressure Processing Preservation method where liquid and solid foods are subjected to pressures of 45,000 pounds per square inch or higher.
