In recent years there has been a considerable pressure from consumers to reduce or eliminate chemically synthesized additives in their foods. Many naturally occurring compounds present in plants have been shown to possess antimicrobial effect against food-borne pathogens. In particular, the antimicrobial properties of plant essential oils (EOs) and their constituents have been widely demonstrated (Burt,2004; Dorman & Deans, 2000). Use of Eos as antimicrobial agents in food systems may be considered as additional intrinsic determinant to increase the safety and shelf life of food.
