Dr. Demirci joins us in this captivating episode to explore the use of pulsed light as an alternative antimicrobial intervention in the food industry.

The first part of his study was dedicated to defining the spectrum and energy characteristics of pulsed light. Following this, Dr. Demirci delved into investigating the germicidal response of a range of microorganisms, including Escherichia coli, Salmonella enterica subsp. enterica ser. Typhimurium, Listeria monocytogenes, Bacillus cereus (vegetative cells and endospores), Aspergillus niger spores, and Penicillium roqueforti spores to pulsed light treatments.

The organisms were treated using three different broad-spectrum xenon gas flashlamps and were subjected to up to 15 pulses. Each microorganism displayed a significant interaction of flashlamp type and treatment duration.
