By gaining the fundamental knowledge on the antimicrobial effects of plant derived PCs on pathogenic microorganisms, it is possible to search new strategies to combine the synergic antimicrobial effects of PCs with their natural biological properties. The results may permit the formulation of new products to be used as food preservatives or to be included in the human diet. Thus, the food industry is interested in developing natural components for the total or partial replacement of synthetic antimicrobials
