Syntheses and Odor Characteristic of Beta-Terpinyl Esters

Our method of snythesis of terpin-1,8 diesters and eliminating one mole of acid made it possible for the first time to produce beta-terpinyl esters with interesting odour properties. This represents a major expansion of the variety of perfumery synthetics produced from turpentine.

Simple Methods of Odor Quality Evaluation of Essential Oils and Other Fragrant Substances

3,6-Dimethyl Octan-3-ol

A profile: 3,6-Dimethyl octan-3-ol. Thus is the history of 3,6-dimethyl octan-3-ol and its chemical evolution over forty years of changes in the flavor and fragrance industry. One wonders what might have been the fate of AR-1 if synthetic linalool had not been made available from the vitamin intermediate stream.

PsychologicalQualities of Odor II: Geometry of Odor Quality

Psychologist's Corner. Multidimensional scaling is the general term for the set of approaches which share the aim of inserting odor stimuli, as points, into a geometrical space of low dimensionality (2-3 dimensions).

Chemical Investigation of Essential Oil of Abutilon Indicum

The plant Abutilon indicum contains 0.15% of essential oil which mainly consists of α-pinene, caryophyllene, caryophyllene-oxide, endesmol, farnesol, borenol, geraniol, geranyl acetate, elemens and 1:8-cineole along with a number of other minor constituents.

Effects of Structural Modifications on the Odour of Jasmone Analogues

The odour of 2-alkylcyclopentanones can be radically affected by substituents on the first or second carbon atoms of the side chain, substituents further along the chain having a much lesser effect on the odour character. It is postulated that these effects could be rationalised in terms of obstruction of the carbonyl group by a substituent on the first carbon of the side chain or disruption of the side chain conformation by one on the second position

Progress in Essential Oils: Yarrow Oil, Spikenard Oil, and Dwarf Pine and Mountain Pine Oils

This month's column discusses the chemical compositions of yarrow oil, spikenard oil, and dwarf pine and mountain pine oils

The Influence of Methyl Group Substitution on the Odour of Aliphatic Nitriles

The interesting odour properties of methyl substituted nitriles, coupled with the typical stability/safety properties of nitriles suggest that they will become valuable perfumery materials.

Odor Experience as an Affective State: Effects of Odor Pleasantness on Cognition

A summary of research conducted for the Fragrance Research Fund. This research is designed to investigate the effects of pleasant and unpleasant odors on a variety of cognitive-behavioral responses.

Organophosphorus and Organochlorine Pesticide Residues in Italian Citrus Oils

The present work summarizes the results of the qualitative and quantitative analyses of organophosphorus and organochlorine pesticides in Italian citrus oils produced from 1983 to 1992.

Market outlook: Organic Essential Oils

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.

Oxygen Heterocyclic Compounds of Citrus Essential Oils

In this paper we report the results on the isolation, identification and quantitative analysis of oxygen heterocyclic compounds of bergamot, sweet orange, mandarin, bitter orange, grapefruit and lemon oils.

Structure/Odor Correlations: the Mechanism of Olfaction and the Design of Novel Fragrance Ingredients

“One has to rely on chemists to find new aroma chemicals creating new, original notes. In perfumery, the future lies primarily in the hands of chemists.”

Enantiomeric Distribution of Volatile Components of Citrus Oils by MDGC

The enantiomeric distribution of volatile components of citrus oils provides a useful parameter for the evaluation of genuineness and quality of the oils.

A Rapid Method of Analysis of Organophosphate Pesticides in Mandarin Essential Oils

Detection and hazard assessment of organophosphate pesticides in industrially distilled and cold-pressed mandarin oils.

Ten Years of Hydrodiffusion of Oils

The differences between the chemical composition, and the olfactive and organoleptic qualities of essential oils obtained by hydrodiffusion or hydrodistillation, can be explained by the way in which the oil is present in the plant material.

Organoleptic Characteristics of Flavor Materials: September October 2003

Mosciano, Michalski and organoleptic evaluation panelists explore a variety of flavor components and applications, such as Butyl Propionate, Cocal Reaction Product, Coffee Essence Concentrate and more
