| Hazard Information | Back Directory | [Description]
Octyl isobutyrate has a fruity, fatty fragrance with a soft and humid
undertone reminiscent of parsley and fern root with a sweet flavor
suggestive of grape. May be prepared by esterification of n-octanol
with isobutyric acid. | [Chemical Properties]
Octyl isobutyrate has a fruity, fatty fragrance with a soft and humid undertone reminiscent of parsley and fern root. It
has a sweet flavor suggestive of grape. | [Occurrence]
Reported found among the volatile components of hop. Also reported found in grapefruit juice and babaco fruit
(Carica pentagona Heilborn). | [Definition]
ChEBI: Octyl 2-methyl-propionyl is a carboxylic ester. | [Preparation]
Esterification of n-octanol with isobutyric acid. | [Aroma threshold values]
Detection: 6 ppb | [Taste threshold values]
Taste characteristics at 30 ppm: creamy, waxy, fruity, earthy and fatty. | [Metabolism]
Isobutyrates are hydrolysed to materials that are either normally in the diet or readily converted to such materials (Fassett, 1963a). Isobutyric acid occurs normally in the metabolism of valine, being converted to a propionyl group and entering into the glycogenic process (Fassett, 1963b). π-Octanol is largely oxidized in vivo; about 10% is excreted conjugated with glucuronic acid in rabbits. Isomeric octanols may be more highly conjugated; they may also be oxidized to the ketone or may be excreted unchanged (Williams, 1959). |
