FEMA 3082 Usage And Synthesis

Chemical Properties

White to yellow liquid; oily, citrus odor. Soluble in alc, fixed oils; insoluble in water.

Chemical Properties

2-Tridecenal has a very strong, citrus-peel, waxy odor with a bittersweet taste.
Powerful, waxy-citrusy, peel-like odor of moderate tenacity. More citrusy than the odor of Tndecanal.

Occurrence

Reported found in grilled and roasted beef, lamb and mutton liver and coriander leaf. Also detected in sunguli oil from Turkmenistan.

Uses

2-Tridecenal is used in minute amounts in flavor compositions, mainly of the Citrus type, but also in fruit complexes, where it introduces great power, diffusion and lift to the aroma, reviving an overly sweet Citrus complex, etc. The concentration in finished products is normally very low, about 0.1 to 8 ppm.

Definition

ChEBI: 2-tridecenal is a fatty aldehyde.

Preparation

From undecyl aldehyde by condensation with acetic aldehyde using sodamide in ether.

Taste threshold values

Taste characteristics at 30 ppm: aldehydic, citrus-like, fatty, green and creamy.

Hazard

Low toxicity by ingestion and skin contact.

Safety Profile

Low toxicity by ingestion and skin contact. When heated to decomposition it emits acrid smoke and irritating fumes.
