The major compound responsible for the objectionable muddy or musty/earthy off‐flavor in Louisiana brackish water clams ( Rangia cuneata )was positively identified as geosmin (trans‐1,10‐dimethyl‐trans‐g‐de‐calol), based on gas chromatographic retention times, electron ionization mass spectra, and odor characteristics. Confirmation was based on analysis of authentic geosmin under experimental conditions comparable to those of the clam samples.
