Product Introduction:

(E,E)-2,4-Decadienal is an unsaturated aldehyde with two conjugated double bonds, specifically the trans,trans isomer, which is the most impactful from an aroma perspective. It typically appears as a colorless to pale yellow liquid with an extremely powerful and characteristic aroma.

This compound is a critical aroma chemical, renowned for its intense fatty, fried chicken, roasted, and deep-fried notes, along with nuances of nuts and sometimes greenness. It is a major contributor to the desirable aromas of fried foods, cooked meats, and fats, and is naturally found in various foodstuffs. Its very low odor threshold makes it highly impactful even at trace levels.

Main Uses:

1. 1. Flavor and Fragrance Industry: (E,E)-2,4-Decadienal is a highly valued impact aroma chemical in both flavor and fragrance formulations, essential for imparting specific fatty, fried, or roasted notes.

   2. Food Flavoring (Chicken & Fried Notes): It is indispensable for creating or enhancing authentic fried chicken, roasted chicken, and other poultry flavors in a wide range of food products, including snacks, sauces, seasonings, and processed meats. It is also crucial for developing general fried and fatty notes in oils, fats, and savory products.

   3. Meat & Savory Flavors: It plays a significant role in developing savory flavors, contributing to cooked meat, roasted nut, and deep umami profiles. It helps to provide the ‘fatty’ mouthfeel and aroma associated with well-cooked proteins.

   4. Confectionery: In very small amounts, it can be used to add complexity or a subtle roasted/nutty note to certain confectionery applications.

   5. Fragrances: In perfumery, tiny amounts can be used to add unique fatty, aldehydic, or subtly roasted nuances, particularly in modern, abstract, or “gourmand” compositions.
