Abstract
This study was carried out to analyze to the flavor components of Lindera obtusiloba BL leaf teas by different processing methods. 81 kinds of flavor components in the masted tea, 78 in the roasted tea after steaming, 88 in the withered tea, 86 in the fermented tea, 72 in the steamed tea, and 89 in the air dried tea ware by GC/MS. Hydrocarbones in Lindera obtusiloba BL leaf teas were 45 kinds of $\beta-piepne$, and 16 kinds of alcohols such as Linalool, n-octanoal, phenyl acetaldehyde, $(-)-\alpha-terpineol$, elemol, and cholest-5-en-3-ol. 11 kinds of ketones sachas 2-ethyl-2- propyl-cyclohexanone, and 8 kinds of aldehydes sach as phenyl acetaldehyde, tetradecanal, 10-undecanal, 4-Bromo-2-methylbutanal were found. Esters were methyl 9,12,15-octadecatrienate, didodecyl phthalace, 1,2-benzenediccarbaboxy acid-bis (2-ethylhexyl)ester and phenols was 2,6-bis(1,1-dimethylethyl)-4-methyl-phenol.
본 연구에서는 우리나라의 전통차의 계승과 새로운 식품의 개발하고자 생강나무의 잎을 이용한 차의 제조방법에 따른 향기성분의 변화를 조사하였다. 재차방법에 따른 향기성분은 덖음차 81종, 찐후덖음차 78종, 자연건조차 88종, 발효차 86종, 찐차 72종 및 인공건조차 89종의 분리할 수 있었다. 생강나무 잎차의 향기성분은 $\beta-piepne$을 비롯한 hydrocarbone류가 45종이 동정되었으며, 가장 많은 종류의 성분이 분포되었다. Alcohol류는 L-linalool, n-octanoal, phenyl acetaldehyde, $(-)-\alpha-terpineol$, elemol, cholest-5-en-3-ol, 등 16종, 2-nitro-2(3-hydroxybuthyl) -clododexanone, 3-(3-butenyl)-2,3-epoxy-cyclohexanone, 2-ethyl-2-propyl- cyclo-hexanone 등 11종의 ketone류가, phenyl acetaldehyde, tetradecanal, 10-undecanal, 4-Bromo-2- methylbutanal 등 8종의 aldehyde류가 동정되었다. 또한 ester류는 methyl 9, 12, 15-octadecatrienate, didodecyl phthalate, 1,2-benzenediccar-baboxy acid-bis(2-ethylhexyl) ester 3종류가 동정되었고, 또한 phenol류는 2,6-bis(1,1-dimethylethyl)-4-methyl-phenol이 동정되었다.
