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.
