Non-thermal processing of foods (high pressure processing, pulsed electric field, irradiation, and pulsed light) offers an alternative to conventional thermal processing to meet consumer demands for convenient, high quality, and minimally processed food products. Non-thermal processes have different mechanisms of preserving foods compared to thermal processes. Thus, the development of packaging for non-thermal processing requires understanding of packaging material properties (mechanical and barrier) and interaction between packaging materials and food components during the non-thermal processes. ...
