• Chemische Eigenschaften

  Undecanal is a colorless liquid with a sweetish, fatty odor with an orange and rose undertone. It has a characteristic flavor. This chemical tends to polymerize unless tightly sealed. It is soluble in oils and alcohol, but insoluble in glycerol and water. Additionally, it is combustible.

• Occurrence

  Reported found in essential oils of citrus peels, lemon, caviar, cooked beef, chicken, lamb, pork, coriander leaf, cucumber, fish, grapefruit juice, apple, orange juice, bilberry, cranberry, raspberry, blackberry, carrot, celery, baked potato, Gruyere cheese, Russian cheese, butter, milk, fatty fish, hop oil, beer, cognac, tea, peanut oil, pecan, starfruit, coriander seed, rice, calamus, buckwheat, red sage, loganberry and maté.

• Verwenden

  Undecanal is a flavoring agent that is a liquid, colorless or pale yellow, with a sweet odor. it is soluble in most fixed oils, mineral oil, and propylene glycol; insoluble in glycerin. it is obtained by chemical synthesis. it is also termed aldehyde c-11 undecyclic and n-undecyl aldehyde.

• Verwenden

  Perfumery, flavors.

• synthetische

  Usually prepared by oxidation of the corresponding alcohol or reduction of the corresponding acid.

• Definition

  ChEBI: Undecanal is a saturated fatty aldehyde formally arising from reduction of the carboxylic acid group of undecanoic acid. It is a component of essential oils from citrus plants like Citrus reticulata. It has a role as an antimycobacterial drug, a volatile oil component and a plant metabolite. It is a saturated fatty aldehyde, a n-alkanal and a medium-chain fatty aldehyde. It is a tautomer of an undec-1-en-1-ol.

• Aroma threshold values

  Detection: 0.4 to 100 ppb

• Taste threshold values

  Taste characteristics at 10 ppm: waxy, buttery, aldehydic, soapy with a citrus note and slight laundry detergent nuance.

• Allgemeine Beschreibung

  Undecanal is a volatile flavor compound identified in grapefruit oil and orange essential oil. It is used as a pharmaceutical intermediate.

• Hazard

  Toxic by ingestion and inhalation, irritant to tissue.

• Flammability and Explosibility

  Not classified

• Sicherheitsprofil

  Low toxicity by ingestion and skin contact. A skin irritant. Combustible liquid when exposed to heat or flame. To fight fire, use CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
