【摘要】：本文研究了櫻桃酒的特征香氣成分,通過(guò)數(shù)理統(tǒng)計(jì)分析不同產(chǎn)地的櫻桃酒與特征香氣成分之間的相關(guān)性。采用頂空固相微萃取(SPME)方法對(duì)不同產(chǎn)地的櫻桃酒進(jìn)行香氣萃取,通過(guò)氣相色譜-質(zhì)譜(GC-MS)聯(lián)用技術(shù)共確定41種香氣成分,通過(guò)外標(biāo)法對(duì)這些香氣成分進(jìn)行定量,并對(duì)數(shù)據(jù)進(jìn)行聚類(lèi)分析(AHC)。對(duì)樣品進(jìn)行GC-O分析,在此基礎(chǔ)上計(jì)算香氣物質(zhì)的香氣活性值(OAV)。OAV≥1的物質(zhì)被確定為特征香氣物質(zhì),共確定15種物質(zhì)為櫻桃酒的關(guān)鍵香氣組分。采用主成分分析(PCA)研究不同產(chǎn)地的櫻桃酒與特征香氣成分之間的相關(guān)性。AHC結(jié)果表明:2個(gè)區(qū)域的櫻桃酒可按產(chǎn)地分類(lèi)。PCA結(jié)果表明:不同產(chǎn)地的櫻桃酒和不同的香氣活性物質(zhì)之間存在一定的相關(guān)性。
[Abstract]:The characteristic aroma components of cherry wine were studied in this paper. The correlation between cherry wine and characteristic aroma components was analyzed by mathematical statistics. The aroma of cherry wine from different areas was extracted by headspace solid phase microextraction (SPME) method. A total of 41 aroma components were identified by gas chromatography-mass spectrometry (GC-MS). The aroma components were quantified by external standard method, and the data were analyzed by cluster analysis. The samples were analyzed by GC-O. On the basis of this, the aroma activity value of the aroma substance was calculated. The substance with OAVN. OAV 鈮，
