Plant equipment for the production of essential oils and aroma chemicals

The flood of information from the literature and the widespread use of advanced analytical instruments have stimulate d the organic chemist to synthesize not only these products occurring in nature but many other useful and interesting homologues.

Volubility Behaviour and Fractionation of Essential Oils in Dense Carbon Dioxide

The extraction with dense gas proves to be a true alternative to the conventional procedures. To obtain essential oils or aroma substances which are used in perfume industries, in the pharmaceutical sector or in the food and human nutrition field, carbon dioxide offers itself as an extractant which is physiologically unobjectionable and leaves the obtained products free of solvents.

The Australian and New Zealand Market for Essential Oils and Aroma Materials

The future for our industry could be phenomenal throughout the region. All we require is the persistence of established producers to recognize the benefits of producing essential oils in Australia and New Zealand.

The Future of Natural Essential Oils in the Flavor and Fragrance Industry

The essential oil industry worldwide remains healthy, although at present there may be over-production for some specific essential oils. With all the progress in the field of chemistry, has the essential oil industry dropped by the wayside, a victim of technological advance? The answer is emphatically no !

Malodor Formation in Alcoholic Perfumes Containing Vetiveryl Acetate and Vetiver Oil

Although hypothetical, the proposed schemes explain reasonably well how butene isomers and 1,1-diethoxyethane can arise from vetivmyl acetate or vetiver oil autoxidation in alcoholic perfumes. Unsaturated perfume ingredients other than vetiveryl acetate or vetiver oil could possibly exhibit a similar behavior.

New Technologies For The High-Speed Characterization and Analysis Of Essential Oils

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).

Aroma Chemicals and Citrus Oils

Natural citrus oils cannot be reconstituted (substituted) by compounding aroma chemicals for three reasons: (1) Citrus oils are complex mixtures, up to 300 chemicals of which many are unknown. (2) If they are known, many are not commercially available. (3) Individual constituents with asymmetric carbon atoms, mostly are optically active, A lot of aroma chemicals are not. On the other hand, aroma chemicals with citrusy odors deserve their own place for compounds in functional perfumery, mainly for stability reasons.

Bulgarian Lavender and Bulgarian Lavender Oil

In spite of the high production costs and the severe competition on the part of some other farm products (such as maize, corn, grapes, tomatoes and other fruits and vegetables), Bulgaria succeeded in preserving unchanged one of its national symbols, the Bulgarian Rose Oil. It has been preserved thanks to age-old traditions, to strict observation of the technology, persistent and careful quality control, the Government’s concern and the extremely high international praise for the oil.

EFEO: The New Voice For Essential Oils and Related Products Facing

Part One. I am an old fashioned guy. I want to smell eau de cologne made with natural bergamot oil. I want to smell the fragrance of citrus or lavender oils in my cleansing agents.

Essential Oils and Aroma Chemicals from Eucalyptus Globulus Labill.

Eucalyptus globulus Labill., which is used in Spain for cellulose and paper production, is grown under an integrated reforestation program. In addition to its importance in the pulp and paper industry, the leaves of E. globulus are used to produce an important essential oil from which 1,8-cineole is isolated. Essential oils can also be obtained from the flowers and fruits of this same tree. Commercial amounts of a resinoid absolute are also obtained from the leaves.

Essential Oil of French Lavender— Its Composition and Its Adulteration

The composition of oil of French lavender is extremely complex. Of the approximately 150 constituents presently identified, most are only present in trace quantities. However, they play a very important role in the overall fragrance of this oil. There are numerous other constituents still to be identified.

Essential Oil Essential Oil Research and Symposia 1969-1989

The time is ripe, perhaps, to review the development which has taken place since the Essential Oil Symposium started in 1969—and try to see a little ahead. The aims of the symposia should be as before: namely, to bring together scientists who are interested in all aspects of essential oil research, for discussions of common problems and presentation of their results, to the benefit of essential oil research in general.

Progress in Essential Oils: Mentha Citrate and Ajowan Oils

This edition discusses the chemical composition of Ajowan oil and Mentha citrata oil.

Coriander seed

Progress in Essential Oils: Coriander Seed Oil and Extract

This edition features the chemical composition of coriander seed oil and extract, and lemon thyme oil.

Development of instrumental analytical methods for essential oils and aroma chemicals

The ultimate purpose of our products and the reason for our industry, to provide consumers with products which please their taste or smell, today and for generations to come has not changed. Safety has always been and will continue to be our most fundamental concern. We are known to respond to problems long before government regulations can be or have to be enacted. Our technology points toward a bright future for the fragrance and flavor industry.

Natural Essential Oils: Extraction Processes and Application to Some Major Oils

This discussion offers a brief overview of the different processes used to obtain natural essential oils. The trend of development in natursl essential oils for the near future will be to: —obtain products free of organic solvents —impove the preparation of the plant matter in order to get better yields —develop aromatic molecules through fermentation

Interrelation of trends in the American fragrance market and the essential oil industry

Continued dialogue and cooperation between essential oil suppliers and creative perfumers must be maintained and strengthened if the growing demands of the American market are to be satisfied.

Selective removal of contact sensitizers from oils and plant extracts

As a number of plant extracts used in the perfume and cosmetics industry contain significant amounts of allergenic components, it becomes very important to develop a mild procedure for the removal of these undesirable substances. We describe here one such method in which the allergens are removed by selective binding to insoluble polymer gels.
