Investigations are conducted searching for new thermal and non thermal methods of fixing food on account of the increasing consumer interest for natural and partially processed food products. One of the best known unconventional methods of preservation is the radiation process. Ionizing radiation is being used for the reduction of microbiological contamination and extension of food freshness. Furthermore, for the majority of food products the process does not influence their chemical composition nor does it lower their nutritional value. These methods are becoming more frequently used in many countries because of their benefits stemming from the improvement of safety aspects of food products.
The modern solutions in the domain of fruit and vegetable packaging systems are sketched in this paper. The principles and practical possibilities of theses systems use are presented. Packaging in gas mixtures (MAP, CAP), active (AP) and intelligent packaging, edible packaging, packaging with the use of high pressures (UHP) and radiation stabilising system are presented.

Consumers are becoming increasingly convinced that highly processed food products may have an adverse effect on their health of, and the effects of these products will only be fully revealed in future generations. The populations of developed countries consider the quality of life as being more important than its length. Thus, consumers in these countries increasingly prefer to purchase foodstuffs which are as natural and unprocessed as possible. Moreover, they prefer to consume long-storage foods, which are both simple and quickly prepared. In order to meet these expectations, non-thermal methods of food preservation have been developed. The three most popular of these which are applied on a practical basis include pulsed electric fields, high hydrostatic pressure processing and irradiation especially in relation to food safety, and the lack of adverse sensorial effects on food products.
