Tentative Title: Supercritical Fluid Extraction of Plant Flavors and Fragrances
Authors: Andrea Occhipinti, Andrea Capuzzo and Massimo E. Maffe
Affiliation: Department of Life Sciences and Systems Biology, University of Turin, Via Quarello 11/A, 10135 Turin, Italy
Abstract: Supercritical fluid extraction (SFE) of plant material with gases like CO2, 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. The published articles on the usage of SFE mostly for pharmaceutical and food processing accounts for about 45% of the specific scientific literature, the remaining percentage being made by articles dealing with extractions with solvents (about 20%), microwave assisted extraction (MAE, about 10%), ultrasound-assisted extraction (UAE, about 10%) and other extraction techniques which are not yet used for industrial applications in large scale (about 10%). Although today SFE is mainly used for decaffeination of coffee and tea as well as production of hop extracts on large scale, there is a growing interest on this extraction method also for other industrial applications operating at different scales. This review describes the SFE technology at both industrial and laboratory scales and gives an overview of its potential in the flavors and fragrances arena.

Title: Production of Flavours and Fragrances via Bioreduction of Cyclic Ketones and Aldehydes by Non-Conventional Yeast Whole-Cells

Abstract: As a part of a program aiming at the selection of yeast strains which might be of interest as sources of natural flavouring molecules, the production of flavours and fragrances via bioreduction of α-β unsaturated cyclic ketones [(4R)-()-carvone] and aldehydes [(1R)()-myrtenal] by non-conventional yeasts (NCYs), belonging to the genera Candida, Cryptococcus, Debaryomyces, Hanseniaspora, Kazachstania, Kluyveromyces, Lindnera, Nakaseomyces, Vanderwaltozyma, and Wickerhamomyces, isolated from the environment was investigated. Volatiles produced were sampled by means of headspace solid-phase microextraction (SPME) and the compounds were analysed and identified by gas chromatography–mass spectroscopy (GC–MS). Yields (expressed as % of biotransformation) varied in dependence of the strain. The reduction of both (4S)()-carvone and R)()-myrtenal were catalyzed by some enoate reductases and/or carbonyl reductases, which determined the formation of (1R,4R)-dihydrocarvone and [(1R)()-myrtenol respectively, as main flavouring products. The potential of NCYs as whole-cell biocatalysts for selective biotransformation of electron-poor alkenes for producing flavours and fragrances of industrial interest is discussed.
Title: Electrochemical Oxidation of Fragrances 4-Allylbenzences and 4-Propenylbenzences on the Platinum and Carbon Paste Electrodes: A Comparative Account
Authors: Lai-Hao Wang*, Yi-Chun,Hu
Affiliation: Department of Medical Chemistry, Chia Nan University of Pharmacy and Science, 60 Erh-Jen Road, Section 1, Jen Te, Tainan 71743, Taiwan.
Abstract: The electrochemical oxidation behaviors of 4-allylbenzences (estragole and safrole) and 4-propenylbenzences (anethole and asarone) on platinum and carbon paste electrodes were investigated in a Britton-Robinson buffer (pH 1.93 -6.42), acetate buffer, phosphate buffer solutions (pH 2.08) and methanol or acetonitrile containing various supporting electrolytes. Their oxidation potential with Hammett (free-energy relationships) and possible mechanisms were discussed.
