Geosmin is a natural organic compound that contributes to the earthy smell often associated with soil and fresh rain. It is produced by certain bacteria and fungi, particularly during the decomposition of organic matter. This compound is responsible for the distinctive scent that many people notice after a rainfall, known as "petrichor." In addition to its role in nature, geosmin can also be detected in various foods, such as beets and some fish. Its presence can influence the flavor profile of these foods, making it an important compound in both environmental science and culinary contexts.
