Progress in Essential Oils: Myrica Gale

Adored by beavers, once found in beers of north western Germany during the Middle Ages and used as an effective insect repellant or a perfumery ingredient, myrica gale oil's constituents can shed new light to formulators on other ways it can be used in F&F.

On the Isolation of Oleoresin Black Pepper by Steam Distillation-Cum-Solvent Extraction and Tailoring of Oleoresin

Using these raw materials--the solvent extractive, supernatant fraction, distilled pepper oil, monocyclic terpenes, piperine factor and diluent--the industry constructs oleoresins of wide variety tailored for many different applications.

Olfactory Perception in Infants

The research reported here was undertaken to develop new methodology for evaluating olfactory perception in infants. Prior research has shown that, while newborn infants are capable of making fine olfactory discrimination, adult-like odor preferences and aversions are not apparent until five years of age.

Synthesis of some substituted pyrazines and their olfactive properties

What we did was to synthesize these interesting compounds; separate and purify each isomer; and characterize each stmcture using GLC, MS, IR techniques, and NMR spectroscopy. The most significant aspect of this investigation was to demonstrate the interesting character they possess and to demonstrate their low odor threshold. These chemicals, afthough expensive, are reasonable in cost vs. level used because of their very low odor threshold. Furthermore, they possess the unique property of synergism.

The flavor of cured vanilla beans contains a complex mixture of aroma and taste compounds.

Olfactory Training of Worldwide Assurance Personnel Quality

The worldwide fragrance, training program is administered by correspondence. Aromatic materials and complete instruction are provided to enable each location to test prospective panelists for olfactory potential, to familiarize panelists with aromatic raw materials which they are likely to encounter during their quality assurance effort, to test the panels on what they have learned and to assist the panelists in any olfactory issues which may arise in the course of their quality assurance effort.

Production of Rosemary Oleoresin Using Supercritical Carbon Dioxide

An outline has been reported of the experiments helpful to appraise current understanding of extract production with supercritical CO2 for use in flavorings and fragrances. Additionally, a recent publication detailed the results of preliminary experiments performed to assess the suitability of employing supercritical CO2 in the production of oleoresins from Rosmarinus officinalis L.

Commercial Perfumery and the Molecular Genetics of Olfaction

The question that has long challenged researchers is: does the olfactory system use a few receptor types to recognize many odor molecules, or does it make use of many receptor types? The definitive answer there is a large and diverse multigene family of receptor proteins. There may be as many as 1000 different receptors in action in the human nose.

The curing of ripe, green vanilla beans convert a generally unflavored pod into the universally recognized and popular aromatic product.
