Technologies used for food preservation using microwaves

Abstract

Food preservation is the process of treating food, with the aim of preserving its qualities for as long as possible. Extending the freshness period for processed foods has been and is a continuing challenge for producers in the food industry. New technologies and conservation methodologies are continuously researched, which will have as little effect as possible on the nutritional value of the products. Microwave food processing is constantly evolving, rapid heating and high energy efficiency are the major advantages of using this technology. The paper presents a study regarding the preservation of food products using microwaves, its acting mechanism and other applications of microwaves for food processing, as well as some installations and equipment that use this technology.
