Modern industrial production of food products is characterized by the use ofcertain additives. The food science, by using the modern diagnostic methods,significantly affects the new findings regarding the harmless or harmfully effect ofcertain substances. The important trends in food industry production of foodproducts today is implementation of natural ingredients. It is possible to obtainextracts (essential oil) with antioxidant characteristics. The paper points out theimportance of certain separation process for isolating natural ingredientsfrom drugs. The aim of this paper is to compare different extraction techniquessuch as distillation with steam, hydro distillation, the application of classicalorganic solvents and supercritical extraction (SCFE) in production of essential oil.To obtain these goals, the following works will be carried out: investigate thechemical composition of essential oil, investigate the effects of quality and yield,the selection of the operating conditions depends on the specific compound orcompound family to be extracted. There are five crucial parameters that need to betaken into account of essential oils including: extraction temperature, extractionpressure, extraction time, CO2 flow rate and particle size. The SCFE method offersmany important advantages over hydro distillation.
