Common Name | 5-Hydroxymaltol |
---|
Description | 5-Hydroxymaltol belongs to the class of organic compounds known as pyranones and derivatives. Pyranones and derivatives are compounds containing a pyran ring which bears a ketone. 5-Hydroxymaltol has been detected, but not quantified in, a few different foods, such as barleys (Hordeum vulgare), breakfast cereal, and cereals and cereal products. This could make 5-hydroxymaltol a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on 5-Hydroxymaltol. |
