Beschreibung
This has a jasmine odor.
Chemische Eigenschaften
Colorless viscous liquid
Chemische Eigenschaften
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.
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.
Verwenden
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.
