Chemical Information
FooDB Name5-Methyl-2-furancarboxaldehyde
Description5-Methyl-2-furancarboxaldehyde, also known as 5-methyl-2-furfural, belongs to the class of organic compounds known as aryl-aldehydes. Aryl-aldehydes are compounds containing an aldehyde group directly attached to an aromatic ring. 5-Methyl-2-furancarboxaldehyde is an almond, burnt sugar, and caramel tasting compound. 5-Methyl-2-furancarboxaldehyde has been detected, but not quantified in, several different foods, such as red raspberries (Rubus idaeus), pepper (c. frutescens), evergreen blackberries (Rubus laciniatus), yellow bell peppers (Capsicum annuum), and rabbiteye blueberries (Vaccinium virgatum). This could make 5-methyl-2-furancarboxaldehyde a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 5-Methyl-2-furancarboxaldehyde.
