Cover Story: Leaf Alcohol Preparation

cis-Hex-3-en-1-ol and trans-hex-3-en-1ol are called leaf alcohols, though their aromas resemble freshly cut grass. Perfumers define their aroma more precisely: cis-hex-3-en-1-ol has powerful and intensely green grassy odor.1 Traces of cis-hex-3-en-1-ol are used in refreshing top notes in delicate floral fragrance types such as muguet and lilac; in addition, the alcohol is often used alongside geranium oil, galbanum, oakmoss, lavender and mint oils.

Leaf Alcohol

Leaf alcohol and its derivatives are a symbol of the “green revolution in flavors and fragrances that developed in our industry during the 1960’s.” Its commercial introduction changed the nature of flavors and fragrances and resulted in the wide spread use of n-hexenyl based materials, Today, more than 40 structurally related aroma chemicals are being utilized in our industry and all at relatively low formula percentages.

Indian Curry Leaf

A member of the natural order of Rutaceae, Murraya Koeniglii (Linn) Spreng, the "Indian curry tree" is a pretty, small shrub or tree up to 6 m in height and 15 to 40 cm in diameter. For years, Murraya koenigii in addition to its therapeutic values, has enjoyed a unique status as a flavoring principle in Indian cuisine.

Citrus materials: Composition of Myrtle Leaf Orange

An in-depth analysis of endocarp composition of this interesting traditional Italian/Sicilian/Calabrian material. Myrtle leaf orange is known as chinotto in Italy and chinois in France, presumably because the fruit originated in China.

Leaf essential oils of three different varieties of Citrus reticulate Blanco growing in Egypt

Paper of the 7th International Congress of Essential Oils, Kyoto, Japan, October 1977. This work was undertaken for the purpose of exploring new sources of citrus oils which may be useful as food flavors and in the fragrance industry. The study deals with the analysis of leaf essential oils of three different varieties of C. reticulata Blanco which flourish in Egypt.

The Chemical Composition of the Leaf Essential Oils from 110 Citrus Species, Cultivars, Hybrids and Varieties of Chinese Origin

We carried out systematic analytical studies on the composition of the leaf oils from 110 citrus species, varieties, hybrids and cultivars of Chinese origin in order to look for new resources for essential oils and provide the systematic chemical-composition data of the leaf oils for the taxonomy of citrus plants.

Black Perigord Truffle Aromatizes: Recent Developments

Production of truffles has decreased in spite of efforts to increase this very valuable crop. Scientists have studied biology, ecology, and biochemistry of the black truflle. Its mode of development is now better known and few innovations have appeared, e.g. specific fertilizer or new cultural techniques. But nevertheless, the present production remains low and the black Perigord trufIle is very expensive; consequently its use in cookery tends to decrease.

Aroma Constituents of Blackcurrant Buds (Ribes nigrum L.)

The classic use of blackcurrant bud absolute is to reinforce and modify natural or artificial blackcurrant flavors. It has also found applications in fragrances, especially in the scenting of lipsticks.

The Composition of Blackcurrant Absolute (Ribes Nigrum)

In our study we employed three different products, an absolute obtained in the laboratory from buds grown in Burgundy of the “Noir Bourgogne” varietv; another laboratory produced absolute from buds collected in Kent, England, from the local variety “Baldwin”; and an industrial produced absolute from buds from various regions of France and elsewhere.

A Review of Oleoresin Black Pepper and Its Extraction Solvents

All the indications are that an oleoresin pepper can be produced at a similar cost to the products now on the market. The physical appearance of this resin may differ a little from the conventional product, but its organoleptic properties are superior in that it lacks the sweet taste and aroma which is so characteristic of culminated solvents.
