Pasteurization is a heating process for packaged and unpackaged foods (such as milk and fruit juice), and usually mild heat treatment below100 C (212 F) is adopted to eliminate pathogens and extend the shelf life. The purpose of this process is to destroy or shut down organisms and enzymes that cause deterioration or disease risk, including vegetative bacteria, but not bacterial spores.
Because pasteurization is not a sterilization method and does not kill spores, the second "double" pasteurization method can kill germinated spores, thus improving the quality. In the process of pasteurization, the deteriorated enzyme will also be inactivated. Nowadays, pasteurization has been widely used in dairy industry and other food processing industries to achieve food preservation and food safety.
