In vitro study of the antifungal activity of chloride species and peroxide hydroxide generated during treatment with pulsed electric field - Potential use as sanitizing equipment and food handling art

In systems with pulsed electric field (PEF), electrochemical reactions can occur in the treatment chamber. This can lead to partial electrolysis of the solutes in the solution and subsequently generate long-lived oxygenic reactive species such as hydrogen peroxide (H2O2) and, in the case of solutions containing chloride compounds, lead to electrolytic production. In this context, the anti-fungal activity of PEF-treated solutions was tested against Penicillium spp, an opportunistic filamentous fungus that has previously been reported to cause infections in immunocompromised patients and to proliferate well in absorbent building materials and able to contaminate and deteriorate various food products, with special attention given to potential mycotoxin produce.
