Chemical Information

FooDB Name

2-Ethylfuran

Description

2-Ethylfuran, also known as alpha-ethylfuran or 2-ethyloxole, belongs to the class of organic compounds known as heteroaromatic compounds. Heteroaromatic compounds are compounds containing an aromatic ring where a carbon atom is linked to an hetero atom. 2-Ethylfuran is a sweet, burnt, and earthy tasting compound. 2-Ethylfuran is found, on average, in the highest concentration within kohlrabis (Brassica oleracea var. gongylodes). 2-Ethylfuran has also been detected, but not quantified in, several different foods, such as cherry tomatoes (Solanum lycopersicum var. cerasiforme), nuts, sweet bays (Laurus nobilis), spearmints (Mentha spicata), and garden tomatoes (Solanum lycopersicum). This could make 2-ethylfuran a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2-Ethylfuran.
