“…Most of them used scCO 2 laboratory-scale extraction installation (up to 2 L extraction vessel) to obtain oils from the most popular fruits, vegetables, or herbs, e.g., grapes, olives, and sunflowers (Yang et al 2011;Rai et al 2016;Aladić et al 2015;Milić et al 2015;Duba and Fiori 2015;Del Valle 2015;Da Porto et al 2012a, b), but only a few of them used supercritical CO 2 industry-scale extraction plant to obtain oils, especially from berry seeds .…”

Oily seed extracts were used as research samples in Analytical Laboratory of Raw Materials and Plant Products. Supercritical carbon dioxide extraction on an industrial scale was used to prepare extracts from raw plant materials, usually berry seeds: blackcurrant, raspberry, strawberry, and chokeberry. Gas chromatography analysis was performed on Agilent equipment with single quadrupole mass spectrometer detector and split/splitless injector. Fatty acids (FAs) were determined using indirect method, where they were converted to c o r r e s p o n d i n g m e t h y l e s t e r s ( FA M E s ) d u r i n g trimethylsulfonium hydroxide solution reaction. Comparing the mass spectrum and retention time peak, more than 30 compounds in different oily extracts were qualitatively identified. Quantification of individual fatty acids was based on two different methods. Firstly, it was based on the received peak area, and the results were normalized without correction factor. Secondly, the quantification was based on external calibration curve, for 34 identified fatty acids. The method was validated, and the results, e.g., linearity, precision, limit of detection (LOD), and limit of quantification (LOQ), were presented.

“…The interest in supercritical extraction has been recently increasing and it is expected that the amount of waste products accompanying this process will increase. The possibility of use of such waste for the production of activated carbons seems not only an attractive method of their utilisation but is also an economic method for obtaining effective adsorbents of pollutants from liquid and gas phase (Reverchon 1997;Rój et al 2013;Zhao and Zhang 2013;del Valle 2015).…”

Removal of NO2 by carbonaceous adsorbents obtained from residue after supercritical extraction of marigold

Carbonaceous adsorbents were obtained from the residue after supercritical extraction of marigold subjected to physical activation and used as nitrogen dioxide and iodine adsorbents. The effect of carbonisation and activation temperature on the textural parameters, acidbase character of the surface and sorption properties of the activated carbons was tested. The materials obtained were activated carbons of low-developed surface area varying from 2 to 206 m 2 /g, showing clearly basic character of the surface. The results proved that proper selection of the carbonisation and activation procedure of the residue after supercritical extraction of marigold permitted obtaining carbonaceous adsorbents with good capacity toward liquid as well as gas inorganic pollutants. The effectiveness of NO 2 removal was found to depend to large extent on the conditions of adsorption. The preliminary wetting of the adsorbent bed was shown to significantly increase the amount of pollutants removed.

“…3 (part b)) as solvents to extract valuable materials [7,28,85]. Supercritical extraction with CO 2 has been widely adopted for isolation of volatile aroma compounds in plants and fruits [7,42,100] and vegetable oils from preprocessed seeds [30,69]. There are some research works concerned with aroma recovery from alcoholic beverages [90] combined with a dealcoholization process [15,64,82].…”

Recovery of volatile flavor-active aroma compounds which are key components of processed liquid food streams is of utmost concern to food industry, as these compounds contribute to the quality of the final product. This review paper highlights the recently published research on different techniques that can be applied for recovery of the key flavor components which all aim for minimizing the loss of volatile aromas and (re-) using them in process streams, in order to enhance the flavor profile of the liquid food product. Among the available techniques for flavor recovery in food industry, distillation or stripping, pervaporation, supercritical fluid extraction, and adsorption showed potential for selective recovery of the flavor components from liquid food streams. These techniques can be combined in different stages of the process or applied as an alternative to the other techniques for aroma recovery. Less attention has been paid to supercritical fluid extraction among the available techniques, especially for recovery of aroma components from alcoholic beverages. Since this technology demonstrated high selectivity for flavor recovery in fruit juices and can take profit from applying natural solvents like CO 2 , further research on the application of this technology combined with counter-current flow in a multi-stage contactor is recommended to optimize the recovery process. Adsorption also shows potential for flavor recovery that can be combined with thermal processing or applied as an alternative standalone technique.
