Automatic control system for pulsed lighting in sterilization of low-heat fermented food packaging. This paper aims to design and prototype an automatic control system for xenon lamps in pulsed lighting, specifically for sterilizing packages of low-heat fermented foods. The system comprises various components, including lamp holders, lenses, ballasts, heat dissipation mechanisms, power supplies, electronic controller boards, power electronic boards, and touch display control boards. The system’s effectiveness is evaluated through the application of a cultured bactericidal test, focusing on Escherichia coli. Variables such as control light source distance, the number of pulses, light intensity, and energy per unit area are considered. Results indicate that the application of pulsed light, with variations in frequency, leads to a reduction in the number of Escherichia coli colonies observed after the optical test
