Study on Effect of Pulsed-light Treatment on Lethality Rate and Living Micro-environment of Penicillium

Abstract

Abstract: The experimental results of treating Penicillium by pulsed light showed that as flashing 48 times, lethality rate is 99.9%, and as input voltage 3000 V, lethality rate of is 99.3%. The sequence influencing on lethality rate is flash frequency > input voltage > bacterium liquid transparency > bacterium liquid depth, and their optimum designs are 48 times, 3000 V, 32% and 3.4 mm respectively. The lethality rate of Penicillium is 99.99% on these conditions. After being treated by pulsed light, Penicillium liquid conduction rate changes positively but temperature does not have obvious any changes.

Key words: pulsed light, lethality rate, Penicillium
