烤煙復(fù)烤煙葉自然陳化過程中感官質(zhì)量變化研究
A Study on the Changing of Sensory Quality of Redried Flue-cured Tobacco Leaves during Aging
-
摘要: 跟蹤鑒定14個烤煙復(fù)烤煙葉樣品在自然陳化7～51個月期間感官質(zhì)量變化情況,。結(jié)果表明，（1）不同產(chǎn)區(qū)各部位復(fù)烤煙葉在濟(jì)南自然陳化感官質(zhì)量隨時間變化情況不同：湖南和黑龍江上部,、中部煙葉陳化23個月感官質(zhì)量達(dá)到高峰,；貴州、山東,、云南,、河南、巴西中部葉最佳陳化時間為34個月,；貴州,、山東、云南,、河南和津巴布韋上部煙葉最佳陳化時間為34～39個月,。（2）感官評吸總分與陳化時間符合二次曲線關(guān)系。（3）不同產(chǎn)區(qū)煙葉自然陳化期間煙葉質(zhì)量變化幅度不同,，以云南煙葉質(zhì)量變化最大,，貴州和黑龍江煙葉質(zhì)量變化最小。云南,、貴州煙葉經(jīng)自然陳化效果較好,。（4）上部煙葉比中部煙葉耐存放，河南煙葉和津巴布韋上部煙葉耐存放,，云南煙葉不耐存放,。（5）香氣量指標(biāo)變化較小，煙葉感官總體質(zhì)量的提高主要由雜氣,、余味和香氣質(zhì)等指標(biāo)變化引起。Abstract: The sensory quality changes of 14 redried flue-cured tobacco lamina samples during aging of 7 to 51 months were evaluated. The results showed that: (1) the best aging time of middle and upper leaves from Hunan and Heilongjiang was 23 months; that of middle leaves from Guizhou, Shangdong, Yunnan, Henan and Brazil was 34 months; and that of Guizhou, Shangdong, Yunnan, Henan and Zimbabwe upper leaves was 34~39 months. (2) The total smoking score was related to aging time through a binomial function. (3) During aging, the quality of Yunnan redried lamina increased the highest, followed by Guizhou, and Heilongjiang. By aging, redried lamina of Yunnan and Guizhou achieved the high quality. (4) Upper leaves endured longer time storage than middle leaves. Henan leaves and Zimbabwe upper leaves endured longer time storage than other samples, but Yunnan leaves could not endure long time storage. (5) During aging, aroma volume increased smaller and the changes of offensive odor, offensive taste and aroma quality were the major reasons of the increase of overall sensory quality .
