Abstract
Among the new preservation non-thermal methods of food preservation, pulsed light technology (PLT) has been prominent in the microbial decontamination. This technology decontaminates food and packaging materials with photochemical and photothermal effects. The PLT involves discharging electrical pulses of higher voltage (up to 70 kV/cm) using a flash lamp containing xenon gas for few seconds through the sample between two electrodes. This chapter discusses the principles, components, different equipments, process parameters, operation, mechanism of inactivating microorganisms and action on enzymes and its applications in food processing and packaging.
