TRANS-4-DECENAL is an unsaturated aliphatic aldehyde with a distinctively potent, fatty, green, metallic, and animalic odor profile, often described as reminiscent of cooked pork, bacon, or even blood. It is a clear, colorless to pale yellow liquid at room temperature. Its chemical structure features a ten-carbon chain with a double bond at the 4-position (trans configuration) and an aldehyde group at the 1-position.
Primarily used as a flavor and fragrance ingredient due to its unique aroma characteristics. It is valuable in creating specific notes in food and perfumery.
In the flavor industry, TRANS-4-DECENAL is crucial for formulating artificial meat flavors, particularly pork, bacon, and cured ham profiles, as well as poultry and beef notes. It can also be found in certain dairy, fat, and oil applications. In the fragrance industry, it is employed in trace amounts to contribute animalic, fatty, or 'dirty' undertones to various perfume compositions, especially those aiming for leathery, meaty, or aldehydic effects. It can also support citrus and green notes.
Generally considered safe for use in food and fragrance applications at low concentrations. However, like many aldehydes, in concentrated form, it can be an irritant to skin, eyes, and respiratory tracts. It is combustible and should be handled with appropriate personal protective equipment (gloves, eye protection) in a well-ventilated area. Ingestion or inhalation of significant quantities should be avoided. Store in a cool, dry place, away from oxidizing agents and strong bases.
