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. | [CAS DataBase Reference]

| Hazard Information | Back Directory | [Chemical Properties]
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. | [Definition]
ChEBI: A 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. | [Preparation]
Usually prepared by oxidation of the corresponding alcohol or reduction of the corresponding acid. | [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. | [Synthesis Reference(s)]
