- Abstract
- Volatile flavor components of bulgogi, broiled beef with its unique sauce, were analyzed through
high vacuum sublimation-gas chromatography-mass spectrometry-olfactometry (HVS-GC-MS-O). Among
60 volatile compounds identified by GC-MS, -caryophyllene was the most abundant,
followed by diallyl disulfide, -phellandrene, acetic acid, and 2-hydroxy-2-butanone.
Thirty-two aroma active compounds were detected by HVS-GC-O conducted on two GC columns of
different polarity (DB-5ms and DB-Wax). The most potent aroma active compounds were methional
(described as boiled potato-like/soy sauce-like), furaneol (described as caramel-like/sweet), 2-
ethyl-3,5-dimethylpyrazine (described as coffee-like/nutty/toasted laver-like), 2-acetyl-2-
thiazoline (described as nutty/popcorn-like/peanut-like) and 3-isobutyl-2-methoxy pyrazine
(described as bell pepper-like/metallic/earthy) . The odor threshold values of potent aroma
compounds were also determined by paired comparison test. Odor threshold values of potent aroma
active compounds were as follows : methional (0.08㎍/L), furaneol (6.25㎍/L), 2-ethyl-3,5-
dimethylpyrazine (1.56㎍/L), 3-isobutyl-2-methoxy pyrazine (0.31㎍/L), 1-octen-3-one (50㎍/L),
2-acetylpyrazine (12.5㎍/L), linalool (89.4㎍/L) , phenylacetaldehyde (78.23㎍/L) , and
allylmercaptan (0.32㎍/L). Although most of potent aroma active compounds in bulgogi had high
FD factor, they were not detected by GC/MS except for 2-ethyl-3,5-dimethylpyrazine, linalool,
and phenylacetaldehyde. These results were strongly related to low odor threshold values.
