Jasmone Chemical Properties,Usage,Production

Aroma

Diffusive, warm-spicy, somewhat fruity, but in dilution more floral odor of good tenacity. Its beauty is truly demonstrated in dilutions below one percent, or in modest amounts in a perfume composition. The pure material has notes reminiscent of Celery seed, some find it "bread-like", others find it "fruity","waxy" etc. Evaluation of a powerful odorant should be undertaken by proper dilution of the material so that nuances can be studied without the inconveniences of odor fatigue.

Description

This has a jasmine odor.

Chemical Properties

Jasmone has a floral, fruity, jasmine odor. cis-Jasmone is widely used in the creation of high quality florals like jasmine and tuberose. Also used in the reconstitution of synthetic essential oils.

Chemical Properties

Colorless viscous liquid

Occurrence

The cis-form is reportedly occurring naturally; it is found in the essential oils of jasmine (3%), jonquil, and Pittosporum glabratum, in neroli oil, in peppermint (Mentha piperita), and in bergamot, apricot, raspberry, cinnamon, corn mint and spearmint oils, beer, tea, soybean and heated beans.

Uses

Traces, often mere fractions of one percent in a perfume oil may introduce just that wanted warmth and deep floral note almost unobtainable with other chemicals.
Jasmone's flavor power is even greater. Concentrations of about 1 ppm have perceptible effect in many fruit flavors, while naturally, concentrations in Mint flavors are higher.

Definition

A ketone found in jasmine oil and other flower oils.

Taste threshold values

Taste characteristics at 25 ppm: woody, bitter, tea, with a citrus and floral nuance.
