“…Low-temperature conditioning prior to milling decreased heat-driven losses of volatile compounds during milling, as attested by a higher extract yield for low-temperature than conventionally milled sample. Extract yield was even larger for the rapidly decompressed sample [94].…”

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.

Urtica dioica L. is perennial plant with remarkable medical properties and has been widely used in folk medicine and as a food. Fatty acids presented in its leaves were extracted applying three different techniques: classic, automated Soxhlet, and supercritical fluid extraction (SFE). SFE was performed at three different pressures (100, 200, and 300 bar) and two different temperatures (40 and 60°C). Obtained extract was analyzed using GC-FID analytical technique in order to obtain fatty acid profile samples. The highest yield was obtained in the case of automated Soxhlet extraction (218.907 mg/g), while the lowest was observed in the case of classic extraction (15.031 mg/g). Soxhlet approach provided the highest yield of saturated fatty acids (173.348 mg/g), while supercritical fluid extraction gave better results in the case of unsaturated fatty acids (60.062 mg/g). Deeper analysis of SFE extracts revealed relationship between extraction parameters (temperature and pressure) and yields of fatty acids where lower pressure ensured higher yield of unsaturated while higher pressure gave higher yield of saturated acids. On the other hand, increasing in temperature at isobaric conditions negatively influenced the yield of fatty acids except in the case of 300 bar where yield was higher at 60°C.

Latin America possesses expansive natural resources, which has attracted scientists from several areas to study means of improving the use of these resources. Supercritical fluids have been used for such purposes in many technological applications. Therefore, this paper provides an overview of Latin America scientific findings on supercritical technologies. Web of Science and Scopus were used as reference databases to search for information dated from 2004-2013. The Latin-American studies were classified into 6 main areas: extraction & mathematical modeling (57%), emerging applications (15%), thermodynamics & fundamentals (9%), reviews & perspectives (8%), reactions in supercritical media (7%) and analytical applications (4%). A compilation of scientific documents from 1994-2003 indicates that supercritical technology has progress greatly over the last 10 years in the major scientific countries in Latin America, such as Brazil, Argentina, Chile, Mexico and Colombia. These advances are associated with the development of new research subjects. Emerging applications, such as micronization and the encapsulation of nanoparticles, adsorption processes, gas sensors development, power generation and bioresidue hydrolyzation, are reported.
