Flavor characteristics of raw Cordyceps militaris significantly different from those of dried one. In the case of raw Cordyceps militaris, major flavor components were composed of 5 alcohols, 3 ketones, 4 phenols, 9 alkanes, and 3 alkenes. The major alcohol was 1-octen-3-ol (22.56%, 1141.3 ng/ml), which contributed to the characteristic green flavor. Ketones (3-ocatone, in particular) were present in the highest concentration in raw Cordyceps militaris. In contrast, major flavor components of dried Cordyceps militaris were composed of 4 alcohols, 4 ketones, 3 furans, 4 pyrizines, 2 dithiazines, 5 phenols, 8 alkenes, 11 alkanes, and 8 fatty acids. Dried Cordyceps militaris had unique sweet aroma of sesame as well as a milky flavor. Green or fruit flavor were rarely detected. In alkanes, 10 cosanes, component of wax were present. Typical flavor components of alkanes such as β-caryophyllen and △-cadinene were also detected. Fatty acids of dried Cordyceps militaris ranged from myristic acid (14 : 0) to linoleic acid (18 : 2). The sweet aroma of dried Cordyceps militaris was mostly due to pryrazines, dithaiazines, and furans. Two dithaizines were identified and characteristics of these flavor components was a roasted bacon flavor. Strong antibacterial activity was observed toward Vibrio spp. such as V. vulnificus, V. cholerae, V. parahaemolyticus. Relatively high antibacterial acitivity was shown toward Bacillus subtilis, B. cereus, Staphyllococcus aureus, and Corynebacterium xerosis.
