N2 - The bactericidal effects of a self-designed device that combines intense pulsed light (IPL), plasma, and ultraviolet irradiation (UV) on granular and powdered foods, and the changes induced in the properties of the samples were studied. Samples were treated by combined IPL-plasma-UV system continuously. A maximum 1.33 ± 0.24-log reduction of microorganisms on sesame seeds were achieved using the combined system, while maximum 1.12 ± 0.18- and 0.59 ± 0.06-reductions were achieved using IPL-only and plasma-only systems, respectively. Using the combined system achieved maximum 0.41 ± 0.04- and 0.51 ± 0.05-log reductions of microorganisms on black pepper powder and red pepper powder, respectively, which have more holes, cracks, and crevices than sesame seeds. Significant changes in water activity, moisture content, and color were found in all samples due to drying caused by fast circulation or plasma treatment. So further research is needed to reduce the changes of the sample properties after the combined system.
