Hi


Could you comment on the follow references?

The emission of volatile compounds is a familiar characteristic of banana ripening. Esters,

alcohols, ketones, aldehydes and phenol esters have been identified as the compounds

emitted by ripening banana fruits.

Moreover I have found a ketone type that smells like banana..

http://en.wikipedia.org/wiki/2-Heptanone

During ripening, the fruits' metabolism develops the ability
to convert some of the fat acids into esters, ketones and alcohols
(such as 3-methyl-1-butanol), which are important volatile compounds
in many fruits with distinct odor (Jiang & Song, 2010;
Lindsay, 1996; Tressl & Drawertl, 1973).

Terpenes, alcohols, aldehydes and ketones directly
contribute to ripe fruit flavor, but esters are the impact compounds.

. Isoamyl acetate is the ketone responsible for the major portion of the banana flavor.
