FEMA 2791 Usage And Synthesis

Description

Nonyl isovalerate has a heavy fruit odor (apple-hazelnut with citrus notes) and a sweet, warm, floral taste. May be synthesized by esterification of n-nonanol with isovaleric acid.

Chemical Properties

Nonyl isovalerate has a heavy fruit odor (apple–hazelnut with citrus notes) and a sweet, warm, floral taste.

Occurrence

Reported found in rue (Ruta graveolens L.)

Uses

Nonyl isovalerate is used in flavour compositions as a modifier in imitation Apple (interesting for Sherbet Ice flavour), Orange and Hazelnut flavours, and Tobacco flavours. It lends a very natural earthy-oily sweetness to Nut compositions, and this effect should be considered in perfumery, too. Concentration in finished flavoured products is normally as low as 0.5 to 2 ppm.

Definition

ChEBI: Nonyl isovalerate is a carboxylic ester.

Preparation

By esterification of n-nonanol with isovaleric acid.
