Chlorine dioxide as antibiofilm of surfaces in the extraction process of maple sap

This project proposes to expand the investigation of the use of chlorine dioxide (ClO2) as an antimicrobial agent in the sap extraction of maple syrup industry. It is well documented that chlorine dioxide exhibits antibacterial, antifungal, disinfectant, air sterilizer, antiviral, etc., properties. However, its mechanisms of action in specific applications, tolerable concentrations, toxicity etc., must be studied to understand its properties as antibiofilm, its impact on surfaces, materials time of life, and the consequences in the relation of surface damages vs bacterial growth.
This proposal describes our protocol of study and characterization of efficacy and safety of chlorine dioxide against biofilms, and the levels of surface degradation and traces of chlorine chemical residues in polyethylene (PE) and polyvinyl chloride (PVC) (pipes commonly used in this industry), in contrast with isopropyl alcohol as the antibacterial agent commonly used in this industry. Isopropyl alcohol has been shown not to be very effective against biofilms, which suggests an urgent call for the investigation of alternative methods since the demand for maple syrup increases year by year, and the quality is seen to be threatened and at risk by bacteria that affect the quality standards of this product.
