Abstract:

Food sterilization is a well-established technology and maybe classified into (1) in-can sterilization and (2) ultra high temperature short-time sterilization (UHT). The first is batch while the second is a continuous process. Both techniques require exposing the food to a high temperature (121°C to 140°C), which destroy all types of microorganisms including spoilage microorganism such as spores. However, in-can sterilization destroys most vitamins and other nutrients while UHT is known to change the flavor of food products such as milk, making it unfavorable by many consumers. Demands of consumers for higher quality and fresh tasting products are growing rapidly, which requires development of new processing technologies. Recently, non-conventional sterilization technologies have gained significant attention, since they have the potential to provide products with a better quality, fresh-like taste, and may even require lower energy. This presentation outlines the possibilities of combining one of the well-known methods of non-thermal processing such as pulsed electric field (PEF), high pressure (HPP), UV, ultrasound, irradiation and cold plasma with heat treatment. The main objective of such combinations of treatments is to lower overall treatment temperature/ time in order to produce food products of high quality. We recently have shown that the combination of PEF with heat could lower sterilization temperature of milk and hence reducing thermal damage to the nutrient in it.
