“…Considering previous studies, the extraction time assumed for rosemary and anise essential oils was 100 min and for fennel essential oil 80 min. 2,23,24 It could be thought initially that an additional cost relative to a fractionation of SFE extracts to obtain the essential oil should be estimated. However, this step is not necessary.…”

In the present work, economic analysis of the production of extracts and essential oils of rosemary (Rosmarinus officinalis), fennel (Foeniculum vulgare) and anise (Pimpinella anisum) by supercritical fluid extraction and steam distillation are discussed. The manufacturing cost (COM) was determined considering that the COM can be obtained in terms of the costs of investment, operational labour, raw materials, waste treatment and utilities. The manufacturing cost was also estimated considering that the essential oil content in SFE extracts varies (50-100%). The analysis showed that the supercritical fluid extraction is economically viable to obtain these vegetable extracts and essential oils. The higher costs of essential oils obtained by steam distillation were mainly caused by the lower yield and the higher energy consumption of this process.

“…Generally, 50-90% total solute is extracted during the CER, therefore the estimation of costs of manufacturing must take in account the best operational conditions allowing the highest solute extraction in the shortest time or lowest amount of required solvent [11,127,[147][148][149].…”

Supercritical Fluid Extraction of Plant Flavors and Fragrances

Supercritical fluid extraction (SFE) of plant material with solvents like CO 2 , propane, butane, or ethylene is a topic of growing interest. SFE allows the processing of plant material at low temperatures, hence limiting thermal degradation, and avoids the use of toxic solvents. Although today SFE is mainly used for decaffeination of coffee and tea as well as production of hop extracts on a large scale, there is also a growing interest in this extraction method for other industrial applications operating at different scales. In this review we update the literature data on SFE technology, with particular reference to flavors and fragrance, by comparing traditional extraction techniques of some industrial medicinal and aromatic crops with SFE. Moreover, we describe the biological activity of SFE extracts by describing their insecticidal, acaricidal, antimycotic, antimicrobial, cytotoxic and antioxidant properties. Finally, we discuss the process modelling, mass-transfer mechanisms, kinetics parameters and thermodynamic by giving an overview of SFE potential in the flavors and fragrances arena.

Original Paper SFE kinetics of bioactive compounds from Helianthus annuus L.The kinetics of the supercritical fluid extraction of bioactive compounds from sunflower using CO 2 as solvent were studied in order to establish an efficient method for this extraction. The influence of time of extraction at different solvent flow rates was investigated. The extraction pressure and temperature were optimized in previous studies and these values used were 400 bar and 508C. The extraction yields and the bioactivity levels of the extracts were also analysed. The results indicate that the most appropriate extraction time is between 120 and 180 min depending on the solvent flow and the pretreatment of the sample. The dried sample extracted at 40 g/min, the congealed sample extracted at the same flow and 180 min, and the dried sample extracted at 25 g/min for 120 min showed the best activity profiles. The extractions were carried out in a pilot plant with an extraction vessel with a capacity of 2 L.
