Common Name | Kahweofuran |
---|
Description | Kahweofuran belongs to the class of organic compounds known as aryl thioethers. These are organosulfur compounds containing a thioether group that is substituted by an aryl group. Kahweofuran has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make kahweofuran a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Kahweofuran. |
