说明

一般說明

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.

應用

• Medium-Chain Fatty Acids Rescue Motor Function and Neuromuscular Junction Degeneration in a Drosophila Model of Amyotrophic Lateral Sclerosis.: This research explores the therapeutic potential of medium-chain fatty acids, including 4-methyloctanoic acid, in rescuing motor function and preventing neuromuscular degeneration in a fruit fly model of ALS (Dunn et al., 2023).


• Identification of muttony-related compounds in cooked mutton tallows and their flavor intensities subjected to phenolic extract from thyme (Thymus vulgaris L.).: The study identifies 4-methyloctanoic acid among other compounds responsible for the characteristic flavor of cooked mutton, demonstrating its impact on food flavor profiles (Wu et al., 2023).


• Effects of Allium mongolicum Regel ethanol extract on three flavor-related rumen branched-chain fatty acids, rumen fermentation and rumen bacteria in lambs.: This paper investigates the effects of Allium mongolicum extract on rumen fermentation and bacteria in lambs, highlighting the role of 4-methyloctanoic acid in flavor formation (Zhao et al., 2022).


• Identification and Inhibition of the Key Off-Odorants in Duck Broth by Means of the Sensomics Approach and Binary Odor Mixture.: This research identifies 4-methyloctanoic acid as a key off-odorant in duck broth and explores methods to inhibit its formation to improve food quality (Pu et al., 2022).
