| | 3-Methylbutyl 3-methylbutanoate Usage And Synthesis |
| Description | Isoamyl isovalerate has a characteristic fruity odor and a sweet
apple-like flavor. May be prepared by passing vapors of isoamyl
alcohol and isovaleric aldehyde over a copper uranium based catalyst at 240 - 280°C in the presence of hydrogen. | | Chemical Properties | Isoamyl isovalerate has a fruity, sweet, apple, apricot, mango-characteristic fruity odor and sweet-apple-like flavor. | | Occurrence | Reported found in the ether oil from leaves of Eucalyptus microcorys, angelica root oil and mastic gum leaf
and fruit oils. Also reported in wine, oil of hop, olive oil, banana, tomato, peppermint and spearmint oil, beer, rum, whiskies, cider,
sherry, plum, quince, cherimoya and lamb’s lettuce. | | Uses | Isopentyl 3-Methylbutanoate is used in method for preparing essence compound of olfactory recognition book suitable for olfactory sense of Chines. | | Uses | As apple essence for flavoring liqueurs and candy. | | Definition | ChEBI: Isoamyl isovalerate is a fatty acid ester. | | Preparation | By passing vapors of isoamyl alcohol and isovaleric aldehyde over a copper–uranium-based catalyst at 240 to 280°C in
the presence of hydrogen | | Aroma threshold values | Detection: 20 ppb; aroma characteristics at 1.0% in ethanol: sweet, fruity, green apple and estry. | | Taste threshold values | Taste characteristics at 15 ppm: green, fruity, estry, apple, pineapple and tutti-frutti | | Synthesis Reference(s) | The Journal of Organic Chemistry, 52, p. 4319, 1987 DOI: 10.1021/jo00228a032 | | General Description | Isoamyl isovalerate is an apple flavor volatile compound mainly found in apple and banana. It is used as a flavoring agent in chewing gums, candies and baked goods. | | Biochem/physiol Actions | Taste at 1.0 ppm |
