Abstract

Volatile compounds in Omangdungi (Styela plicata)-Doenjang (soybean paste) stew were analyzed using solvent-assisted flavor evaporation/gas chromatography/mass-selective detection/olfactometry (SAFE/GC/MSD/O) and aroma extract dilution analysis (AEDA). The GC/O analysis detected 37 volatile compounds, of which 32 were positively identified, and included 9 aldehydes, 5 alcohols, 4 aromatic hydrocarbons, 4 ketones, 3 esters, 3 N-containing compounds, 2 acids, 1 S-containing compound, and 1 furan. Nine aroma-active odorants ($\log_3FD{\geq}3.0$) in the sample included six compounds derived from Doenjang (3-methyl(thio)propanal, tetramethylpyrazine, 4-vinyl-2-methoxyphenol, 2-acetylpyrrole, butyric acid, and 2-methoxyphenol) and three compounds from Omangdungi (2-acetyl-2-thiazoline, 9-decanol, and 6-decenol). Three compounds derived from Omangdungi (9-decanol, 6-decenol, and 6-nonenol) were thought to enhance the seafood-like flavor of Omangdungi-Doenjang stew.
