Market outlook: Organic Essential Oils
By: Andrew Walter, Earthoil Plantatoins Ltd.
An evolving sector’s benefits, legislation and use in the flavor and fragrance industry. How can the present and future prospects of organic natural products be judged, and can they become important contributors to the total market — either now, or in the future? Organic essential oils — like organic vegetables and fruit — often are regarded as an oddity.

Learning from nature: High-Impact Aroma Chemistry
By: David Brassington, Oxford Chemicals, Ltd; and …
The challenges and opportunities of sourcing high-impact aroma chemicals from nature. As part of a long-term program to source more natural high-impact aroma chemistries (HIAC), Oxford Chemicals Ltd. (OCL) and the Center for Bioactive Chemistry, Durham University, have been collaborating on the bioproduction of sulfur-containing volatiles. Robert Edwards (Durham University) and David Brassington (OCL) examine some of the technical challenges and opportunities of sourcing HIACs from nature.

Progress In Essential Oils
By: Brian M. Lawrence
Bergamot Oil A number of years ago, Frey (1988) used the selective ion monitoring function of GC/MS to detect the addition of synthetic linalool and linalyl acetate by determining their impurities (dihydrolinalool and dihydrolinalyl acetate). He found that the addition of as little as 2% synthetic linalool and linalyl acetate to genuine bergamot oil could be detected.

New Technologies For The High-Speed Characterization and Analysis Of Essential Oils
By: Tincuta Veriotti, Megan McGuigan and Richard S…
Dramatic reductions in characterization and analysis times for essential oils were achieved using high speed gas chromatography (HSGC) and time-of-flight mass spectrometry (TOFMS). High-speed separations were achieved with relatively short capillary separation columns operated with high carrier-gas flow rates and fast temperature programming. Unique features of TOFMS include high spectral acquisition rates and spectral continuity (constant ion-abundance ratios across chromatographic peak profile).
