Odor Description:"Goaty", sweaty-fatty: so-called "soo" odour of mutton
Taste Description:fatty
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.
