Synthesis and odor characteristics of some analogs of acyclic sesquiterpenoids

In summary, it could be stated that the crucial factors affecting the odor of the compounds under investigation are the carbon chain structures and type of functional groups. These observations confirm Beets’ thesis that “the profile of a molecule with an easily accessible functional group is responsible for the odor type.

Comparative Investigations Of The Essential Oil And Volatiles Of Spearmint

Essential oils and extracts of Mentha spicata have long been of high importance in food-product, perfumery and cosmetic applications due to their intense, pleasant, clear-fresh odor. In addition to this species of the Labiatae family, Mentha piperita L. (peppermint) and Mentha arvensis L. (cornmint) are also used extensively.8

Comparative Investigations of the Essential Oil and Volatiles of Spearmint

The objective of this work is to identify the fragrance compounds of this oil and its SPME-headspace by means of gas chromatographic- spectroscopic (GC and GC/MS using different polar and chiral phases) and olfactoric methods (GC-sniffing technique and olfactory correlations) to find out the importance of each single constituent with their specific odor attributes, responsible for the characteristic and pleasant spearmint aroma for the first time.

Progress in Essential Oils: Cinnamon Bark Oil and Extract, and Helichrysum Oil

In his regularly featured column, consultant Brian Lawrence reviews the findings of a number of researchers on the constituents in various essential oils. This month, he highlights two oils: cinnamon bark oil and extract, and helichrysum oil.

Essential oil of Artemisia Pallens Wall (Davana): a study of minor constituents

Artemisia Linn is a large genus, comprising some 280 species found in the northern hemisphere. About 34 species occur in the temperate region of the north western Himalayas (W.I.R.M, 1948). Artemisias are bitter aromatic herbs or low shrubs often with much divided leaves and inconspicuous flowers borne on numerous small heads. Some of them are medicinal and are the source of santonin, a valuable anthelmintic drug. Several species yield essential oil and a few are reported to be useful as fodder. The species which are used for production of essential oils are A. absinthium Linn. and A. dracunculus Linn. Artemisia pallens is a minor item in the essential oil trade and is produced only in India.

The Composition of the Volatile Fraction of the Italian Citrus Essential Oils

The annual production of citrus fruits in Italy amounts to about 3,500,000 tons, 31% of which goes to the transformation industries

The most noted aspect of massoia lactone was the coconut impact. So, imagine all things coconut, including piña colada, coconut macaroons and those Girl Scout cookies we all love.

Application of Gas-Liquid Chromatography to the Analysis of Essential Oils

GLC fingerprint chromatograms of five essential oils.

Contribution to the study of the chemical composition of the essential oil from the terminal branches of the cypress tree in the Grasse area

In a previous study of the chemical composition of the essential oil derived from the Algerian cypress, we compared the oil with oil obtained by steam distillation of the terminal branches of cypress trees from the Grasse area. We then noted some differences that affected the relative proportions of certain constituents. The richness in high constituents, in particular, prompted us to begin the study of this higher fraction. Cypress essential oil possesses a dry-down odor which is both woody and amberlike and is greatly appreciated by perfumers; this also makes it worth studying.

Spray Drying of Food Flavors. Ill. Optimum Infeed Concentrations for the Retention of Artificial Flavors

The practical aspects of this work are that each flavor encapsulating material will exhibit an optimum concentration for flavor retention. The optimum concentrations determined in our study may not necessarily be the same as in a production facility. This would have to be determined using actual production equipment. If the retention is limited by the ability to atomize, this factor is equipment dependent. It does appear worthwhile to make this determination, however.

Green bell pepper, mushroom, celery, and potato/potato chip among others came up as options for cis-3-hexenal.

Flavorist Panel Evaluates Syringaldehyde, Turmeric Root CO2 Essential Oil, Buchu Oil and Other Materials

Headspace Measurement of Evaporation Rates of Perfumes Applied onto Skin: Application to Rose Essential Oils and Their Principal Components

The goal of this research was to study, by headspace analysis, the diffusion of the major components essential rose oils applied onto skin.

Rational Odorant Design: Fantasy or Feasibility?

Exploring the two approaches to rational odor design and the possibilities of each. Why do we strive for rational design of odorants? Since the birth of synthetic organic chemistry in the mid-19th century, fragrance chemists have sought to design and produce fragrance ingredients to supplement those obtained from plant (and formerly animal) sources.

Characterization of Italian Citrus Petitgrain Oils

Compositions of Italian industrial bitter orange, lemon and mandarin petitgrain oils, and of laboratory-extracted and commercial samples of sweet orange petitgrain oil, are reported in this paper.

The sensory psychologyof odor mixture: Changes in odor strength and odor hedonics

Psychologist's Corner. This report is concerned with research efforts on odor-mixture perception. In most of the studies reported here investigators systematically mixed together two (or perhaps a larger but still manageable number of) chemicals in a limited range of concentrations, rather than trying to imitate nature in her mélange of ingredients. Two major aspects of odor mixture, the perception of odor intensity in these mixtures and the perception of odor hedonics, are discussed.
