EXTRACTION TECHNIQUES FOR MEDICAL AND AROMATIC AND MODERN INDUSTRIAL PRODUCTION OF FOOD PRODUCTS

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

THE INFLUENCE OF THE OWNERSHIP STRUCTURE ON AN ENTERPRISE’S EFFICIENCY REGARDING THE PRODUCTION OF MEDICAL AND AROMATIC HERBS

The importance of medical and aromatic herbs in the pharmaceuticals industry and other industries increased in this country and in the world market during the 1980’s. In Serbia and Montenegro, there are appropriate natural conditions for growing medical and aromatic herbs. However, the production and production-related economic effects, as well as those related to medical and aromatic herbs processing and their placement are far from being even close to potential possibilities. The production of medical and aromatic herbs has been accompanied by a plethora of hurdles. The privatization that has taken place has not reflected expected results. Moreover, the production, processing and export of medical herbs are far from the level achieved at the end of the 1980’s. Therefore, it is necessary that the privatization models utilized in the privatization of these enterprises should be reviewed. It is also necessary that a privatization model and ownership structure should be proposed in order to accomplish satisfying results
