烤煙主要化學(xué)成分與感官質(zhì)量的相關(guān)性分析
Correlationship between Main Chemical Components and Sensory Quality of Flue-cured Tobacco
-
摘要: 對我國15 個省及部分進口煙葉樣品化學(xué)成分指標(biāo)與感官質(zhì)量指標(biāo)間進行了簡單相關(guān)分析,。結(jié)果表明，所有化學(xué)成分指標(biāo)均與總體感官質(zhì)量呈顯著或極顯著的相關(guān)關(guān)系,，與總體感官質(zhì)量的相關(guān)程度由大到小排序依次是：總氮-＞煙堿-＞總糖+＞兩糖差+＞有機鉀+＞還原糖+＞糖堿比+＞無機硫-＞鉀硫比+＞兩糖比-＞鉀氯比+＞氮堿比+＞總氯-＞總鉀+(指標(biāo)的上標(biāo)為“-”表示與總分負相關(guān),，上標(biāo)為“+”表示與總分正相關(guān))。研究認為,，相對于兩糖比指標(biāo),、煙葉的兩糖差與感官質(zhì)量的關(guān)系更為密切，相對于總鉀,、氯,、鉀氯比等指標(biāo)，無機硫,、有機鉀與燃燒性及感官質(zhì)量的關(guān)系更為密切，兩糖差,、無機硫,、有機鉀可作為煙葉品質(zhì)評價的重要指標(biāo)。Abstract: The relationship between chemical component indices and sensory quality indices of tobacco leaves from 15 provinces and abroad has been analyzed by simple correlation analysis. The result showed that all chemical component indices had significant or extremely significant correlations with total score of sensory quality. The correlations listed in order of correlative degree from big to small were total nitrogen-＞nicotine-＞total sugar+＞the difference between total sugar and reducing sugar+＞organic potassium+ ＞reducing sugar+＞the ratio of reducing sugar to nicotine+＞inorganic sulfur-＞the ratio of potassium to sulfur+＞the ratio of reducing sugar to total sugar -＞the ratio of potassium to chlorine+＞the ratio of total nitrogen to nicotine +＞total chlorine-＞total potassium +(the superscript of chemical index signed for “-”expressed that the chemical index negatively correlated with total score of sensory quality, and for “+”, contrary ). The research suggests that the difference between total sugar and reducing sugar has more close relationship with sensory quality compared with the ratio of reducing sugar to total sugar, and that inorganic sulfur, organic potassium have more close relationships with combustibility and sensory quality compared with total potassium, total chlorine and the ratio of potassium to chlorine. The difference between total sugar and reducing sugar, inorganic sulfur, organic potassium could be used as important indices for evaluation of quality of flue-cured tobacco.
