Isoamyl Acetate
Isoamyl acetate is an ester aroma component with a distinct banana and tropical fruit scent. Its aroma is lively and diffuses quickly, making it a key top note ingredient in fruit fragrances used to create an “instant recognition” effect.
Type
Fruity
The aroma is sweet and bright, a typical scent of ripe banana, accompanied by associations with tropical fruits such as pear and pineapple. The scent is light and direct, with a very high degree of recognizability and a strong initial impact.
Acquisition Methods
Natural extraction or chemical synthesis
It is naturally present in the aroma of fruits such as bananas and pears, but industrial applications are mainly synthetic. It is produced by esterification of isoamyl alcohol and acetic acid under catalytic conditions. The process is mature and suitable for large-scale stable production.
