Abstract

Flavor compounds in Neungee (sarcodon aspratus) were extracted by simutaneous distillation and extraction (SDE), supercritical fluid extraction (SFE) and headspace method. Flavor compounds obtained by various extraction methods were analyzed with GC and GC-MS. The funtionality of flavor compounds were determined by aroma extract dilution analysis (AEDA) of GC-ofactometry methods. Fifty one flavor compounds were totally identified in Neungee mushroom. However, the numbers of flavor extracted SDE, SFE and headspace were 33, 26 and 17 respectively. The major flavor compounds obtained by SDE, SFE and headspace were 1-octen-3-ol, 1-octen-3-one, 3-octanone, 2-octen-1-ol, 3-octanol, 1-octanol and benzenealdehyde. As the results of sniffing test, the major flavor compounds were found to be fresh mushroom flavor, wood flavor, refreshing sweet flavor, mold flavor, bitter-mushroom and metalic-flavor.

능이버섯의 향기성분을 조사하기 위하여 SDE, SFE, headspace 로 추출하고 GC, GC-MS로 동정하였으며, 능이버섯의 향기특성을 조사하기 위하여 GC-olfactometry 방법중 AEDA법을 이용하였다. 그 결과 SDE 추출물에서는 33개, SFE추출물에서는 26개, headspace 추출물에서는 17개의 화합물이 동정되었다. 확인된 화합물의 주성분은 1-octen-3-ol, 1-octen-3-one, 3-octanone, 2-octen-1-ol, 3-octanol, 1-octanol 등의 $C_8$ 화합물과 benzeneacetaldehyde등이었다. AEDA 결과 능이버섯의 주된 향기특성으로는 생능이버섯내(unknown), 생버섯내(1-octen-3-ol), 곰팡이내(1-octen-3-one), 흙내(3-octanol), 풀내(1-octanol), 강한 풀내(2-octenal), 단 꽃내(benzeneacetaldehyde), 목재내(L-linalool), 치즈내(3-hydroxy-2-butanone), 상큼한 단내(2-decanone), 약간의 불쾌한 고기내(3-methyl thiopropanol), 시큼한 우유내(propanoic acid) 등으로 나타났다.
