Product Introduction:
(2E,4E)-2,4-Octadienal is an unsaturated aldehyde with two conjugated double bonds, specifically the trans,trans isomer. It typically appears as a colorless to pale yellow liquid with a potent and characteristic aroma. This compound is a significant aroma chemical, known for its intense fatty, green, waxy, fried, and slightly metallic notes. It is a key contributor to the aroma of fried foods, fats, and oils, and is naturally found in various foodstuffs, including some dairy products and cooked meats. Its very low odor threshold makes it highly impactful even at trace levels.
Main Uses:
-
Flavor and Fragrance Industry: (2E,4E)-2,4-Octadienal is a highly valued impact aroma chemical in both flavor and fragrance formulations, essential for imparting specific fatty, green, or fried notes.
-
Food Flavoring (Fatty & Fried Notes): It is indispensable for creating or enhancing fatty, fried, and roasted notes in a wide range of food products. It is crucial for developing authentic flavors in oils, fats, snacks, deep-fried foods, and certain meat products. Its waxy and green nuances also find application in specific vegetable and dairy-like profiles.
-
Meat & Savory Flavors: It plays a significant role in developing savory flavors, contributing to cooked meat, poultry, and fish profiles. It helps to provide the ‘fatty’ mouthfeel and aroma associated with well-cooked proteins.
-
Dairy Flavors: In small amounts, it can contribute to specific fatty or ‘creamy’ nuances in dairy or butter flavor formulations.
-
Fragrances: In perfumery, tiny amounts can be used to add unique fatty, green, or aldehydic nuances, particularly in modern, abstract, or “fresh-air” compositions.
