Preservatives used in the Agro-food industries may be of natural origin or obtained chemically. Because of the increasing interest of consumers in food products that contain only natural ingredients, studies on preservative molecules of natural origin, such as organic acids or peptides, have been reported in the past several years. Such studies, which require numerous assays, may be limited by the large amount of molecules required. Microscale assays provide an opportunity for testing natural components available in low quantity. This study examined a rapid method that used microplates for the evaluation of antimicrobial substances. The method was validated using five foodborne pathogens. It required a low amount of product and was convenient for the determination of correlations between the bacterial growth inhibition and concentration of the antimicrobial substance.
