Abstract:
Pulsed Electric Field (PEF) technology is an emerging non-thermal food processing technology, and has been widely used because of its little damage to food quality and ability to kill harmful microorganisms in food. PEF activates the nutrient synthesis pathway of plant foods through the oxidative stress pathway, induces nutrient synthesis, and improves food quality. However, there are few studies in this field. PEF intiates oxidative stress reactions, resulting in the synthesis and accumulation of nutrients. Plant foods are stimulated by PEF to produce large amounts of reactive oxygen species (Reactive Oxygen Species, ROS), which activate metabolite synthesis pathways, eventually leading to the synthesis ofproteins, polyphenols, thioglucosides and carotenoids; The accumulation of ROS on the cell membranes of microorganisms would cause abnormal protein expression, damage to the lipid layer and deoxyribonucleic acid (Deoxyribonucleic Acid, DNA), and eventually cause microbial inactivation.
