| Hazard Information | Back Directory | [Description]
4-Methyloctanoic acid has a fatty, musty, plastic odor. | [Chemical Properties]
4-Methyloctanoic acid has a fatty, musty, plastic odor. This compound is also reported to have a goat, costus, mutton
odor | [Chemical Properties]
Colorless liquid | [Physical properties]
4-Methyloctanoic acid is one of the acids mainly responsible for the so-called "soo" odour of mutton. The analogue 4-Ethyloctanoic acid (found in Virginia tobacco and Costus root oil) also has a related goaty odor; this analog has the lowest threshold of all the fatty acids at 1.8 ppb. 4-Methyloctanoic acid is used in flavours for cheese, meat, tobacco and (possibly) fish. Normal use levels in finished consumer product: up to 3 ppm. | [Occurrence]
Reported found in cooked mutton fat, raw and cooked mutton, lamb, and blue, cheddar, parmesan, provolone
and romano cheeses | [Uses]
Hircinoic Acid, can be used as flavors and fragrance additive. It is also a building block use din sythesis of various chemical compounds such as, rac-Mono-(4-methyloctanyl)-phthalate (M566530). | [Definition]
ChEBI: 4-methyl-octanoic acid is a medium-chain fatty acid. | [Aroma threshold values]
Aroma characteristics at 1.0% in PG: waxy, fatty, meaty, reheated beef-like with a slightly lactonic cheesy
nuance | [Taste threshold values]
Taste characteristics at 10 ppm: fatty, waxy, creamy and lactonic with a satiating fatty mouthfeel and metallic nuances. | [General Description]
4-Methyloctanoic acid is a branched fatty acid commonly used in the flavor and fragrance industries. This compound gives sweaty and goaty flavors to the mutton meat and goat′s milk cheese, respectively. | [Biochem/physiol Actions]
Taste at 10 ppm | [storage]
Store at -20°C |
