Chemical Information
FooDB Name2-Heptenal
Description(2E)-2-Heptenal, also known as 2-trans-heptenal or 3-butylacrolein, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, (2E)-2-heptenal is considered to be a fatty aldehyde (2E)-2-Heptenal is an almond, fat, and fatty tasting compound (2E)-2-Heptenal is found, on average, in the highest concentration within safflowers (Carthamus tinctorius) (2E)-2-Heptenal has also been detected, but not quantified in, several different foods, such as blackberries (Rubus), evergreen blackberries (Rubus laciniatus), cucumbers (Cucumis sativus), roselles (Hibiscus sabdariffa), and common grapes (Vitis vinifera). This could make (2E)-2-heptenal a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on (2E)-2-Heptenal.
