In the following chapters, firstly the antimicrobial and antioxidant properties of essential oils will be discussed, their methods of action, chemical structure of those plant-derived compounds, and the reasons behind why they have the potential new alternative to synthetic preservatives. The chapters discussing the application of essential oils in certain group of food in this compilation will be seafood, meat, vegetables and fruits and bakery products. The areas of interest regarding these food items are in the effectiveness of different essential oils, which are concluded from the results of many research and experiments taken. As essential oils are potential preservative alternatives, it is important to investigate their toxicity and safety for commercial use as well as their organoleptic impact which would affect the consumers’ acceptability. Some products containing essential oils which have met the governmental regulations and are in use in real life as preservatives will be listed and described as well as what the future brings for essential oils and their on-going research.
