Non-thermal food processing irradiation can be used for frozen foods and is the only preservation method available for the inactivation of pathogenic . Called non-thermal food preservation methods, this new and emerging preservation techniques work by killing the microorganisms and inhibiting its enzymatic activity exerting a minimal impact on the nutritional and sensory properties of foods for an extended shelf life.

Promoting intense research on alternative methods for food preservation most foods are less energy than thermal processes nonthermal processing of foods and . Food preservation: food preservation, any of a number of methods by which food is kept from spoilage after harvest or slaughter such practices date to prehistoric times. The basic characteristics of food preservation technologies addressing chemical, biological, thermal and non-thermal processes is presented below thermal food preservation heat processing of foods is designed to result in a specific reduction in numbers of foodborne pathogens or elimination of food spoilage organisms in the target product .

Since the non thermal methods are used for bulk quantities of foods, these methods of food preservation are mainly used in the large scale production the cost of equipments used in the non thermal processing is high when compared to equipments used in thermal processing. Non-thermal plasma as a new food preservation method, its present and future prospect atmospheric pressure plasma (app) is an emerging non thermal technology for the improvement of food safety. Comparing non-thermal food preservation techniques shows foodborne microbial resistance and sensitivity varies with pathogen and food matrix conditions. Food deteriorate in quality due to a broad scope of chemical and enzymatic reactions added to this the consumer demands faster production rate for high quality nutrient with “fresh-like” features and long shelf life taking to the application of thermic procedures for nutrient saving.
