Optimizing the process of supercritical extraction of lemon balm (Melissa Officinalis L.)

This work investigates the process of extraction of lemon balm (Melissa officinalis L.) by treatment with carbon dioxide at supercritical conditions. The process kinetics is studied at different operational conditions, and the influence of some important regime parameters (pressure, temperature particle size, solvent flow-rate) on the extraction yield is experimentally determined. Besides the information for process intensity at particular operational regimes, the results are useful for selection of favourable operational conditions for better extraction, i.e. for production of larger quantity of extracted substances from unit mass of raw material

Finalizing of UP2UML Project

The outcomes of the Upskilling UML are represented. Our team participated in this European project funded by the European Commission under the Leonardo da Vinci program between October 2005 and November 2007. The project aims to enhance UML skills for software development in small and medium enterprises. A proper new learning content for UML was designed and developed. Besides, innovative course production tools were applied and new training approaches were tested and their methodological results were delivered. In the context of general description of the project outcomes we represent here the contribution of our team
