Chemical Information
FooDB NameMethyl isobutyrate
DescriptionMethyl isobutyrate belongs to the class of organic compounds known as methyl esters. These are organic compounds containing a carboxyl group that is esterified with a methyl group. They have the general structure RC(=O)OR', where R=H or organyl group and R'=methyl group. Methyl isobutyrate is an apple, floral, and flower tasting compound. Methyl isobutyrate has been detected, but not quantified in, several different foods, such as fruits, lowbush blueberries (Vaccinium angustifolium), blackberries (Rubus), herbs and spices, and potatos (Solanum tuberosum). This could make methyl isobutyrate a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Methyl isobutyrate.
