Запах

The odour is green, melon-like, earthy, waxy and fresh, with vegetative and floral nuances. At 10% in triacetin the odour is green, oily, earthy, leafy and floral. It is also described as green, vegetal, floral, waxy and slightly earthy, with a cucumber and melon effect. The main aldehyde of the absolute, (2E,6Z)-2,6-nonadienal, has an odour described as green, fatty, dry, cucumber, violet leaf and melon. This contrasts with the powdery, floral scent of violet flowers. The aroma is cool, powerful and wet, of crushed green leaves, with soft woody nuances. During the long dry down it becomes muted, earthy and grassy. Egyptian material is more intense with a distinct leathery undertone, while French-origin leaves tend to have a cleaner, grassier aroma. The absolute has a very powerful and characteristic odour.

Теруар і переробка

Докладно

The plant

Viola odorata is a small, hardy herbaceous perennial of the family Violaceae, native to Eurasia. Its leaves are kidney-shaped and reach 6 cm in length. The leaves and flowers are edible and have been used to make fragrances.

The species is native to Europe south of Scandinavia, northwest Africa, Macaronesia, the Caucasus, Western Asia and Kazakhstan. In some Viola species the scent of the flowers is elusive, because a major component of it, the ketone ionone, temporarily desensitizes the receptors of the nose.

Chemistry

The main constituent of the volatile fraction of the absolute is (2E,6Z)-2,6-nonadienal, the violet leaf aldehyde, also known as cucumber aldehyde. The molecule is a doubly unsaturated derivative of nonanal. Isotopic labeling has indicated that it is formed from α-linolenic acid. The molecule is an α,β-unsaturated aldehyde with an isolated alkene group. The same compound is also found in bread crust and in freshly cut watermelon.

Production and origin

The absolute is produced in small quantities, for example in Egypt.

Absolutes in general are concentrated, oily mixtures with a higher concentration of aromatic substances and a lower volatility than essential oils.

Tourrettes-sur-Loup

Tourrettes-sur-Loup is a commune in the Alpes-Maritimes department of southeastern France, between Vence and Grasse. It holds an annual violet festival in March. A museum dedicated to the violet flower opened in the village on 6 March 2010.

У парфумерії

Violet leaf absolute is used frequently in perfume compositions, but only in very low concentration because of its intense odour. The recommended usage level is up to 2% in the fragrance concentrate. In natural perfumery it is used in herbaceous bouquets, floral bases, chypres and new mown hay. It blends very well with tuberose, narcissus, tea leaf absolute, clary sage absolute, estragon, cumin, basil and with synthetic ingredients. In cosmetic applications it brings a delicate caring effect. In flavour, it is useful in creating green fruits such as melon and kiwi, cucumber, and yellow fruits such as peach and nectarine.
