2、氨、氮堿比在整個醇化階段無明顯變化,總揮發(fā)酸和pH值在醇化結(jié)束時與醇化前期相比,存在顯著差異。②香氣成分除新植二烯外都有一定程度的增加,美拉德反應(yīng)物、類胡蘿I、素降解產(chǎn)物含量在不同醇化階段差異達到了顯著水平。③不同醇化階段片煙感官質(zhì)量均存在顯著的差異,醇化12~15個月時,評吸總分達到最高,隨著醇化的繼續(xù)進行,評吸總分逐漸降低。④典型相關(guān)分析結(jié)果表明,不同醇化階段片煙化學(xué)成分和香氣成兮與感官質(zhì)量之間關(guān)系密切,存在顯著相關(guān)關(guān)系。關(guān)鍵詞:片煙;醇化;化學(xué)成分;香氣成分;感官質(zhì)量中圖分類號:S572文獻標(biāo)
