Chemical Information
FooDB NameMellein
DescriptionMellein, also known as (R)-mellein, is a member of the class of compounds known as 2-benzopyrans. 2-benzopyrans are organic aromatic compounds that 1-benzopyran, a bicyclic compound made up of a benzene ring fused to a pyran, so that the oxygen atom is at the 2-position. Mellein is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Mellein can be found in cocoa powder, which makes mellein a potential biomarker for the consumption of this food product. Mellein is a dihydroisocoumarin, a phenolic compound produced by Aspergillus ochraceus .
