摘要: 摘要: 为进一步探索烟叶分切加工的化学物质基础,以河南浓香型初烤烟叶为材料,从叶尖到叶基分切成10段(HN-1~HN-10),利用单因素方差分析、相关回归分析研究了叶片不同分切区位非挥发性有机酸含量的变化,并基于非挥发性有机酸含量对不同区位进行聚类分析和感官评价。结果表明:①不同分切区位非挥发性有机酸总量平均为124.22 mg/g,变幅为41.70~193.40 mg/g,各组分平均含量表现为苹果酸(89.38 mg/g)>草酸(18.07 mg/g)>柠檬酸(13.48 mg/g)>丙二酸(3.13 mg/g)>丁二酸(0.17 mg/g);②草酸和丙二酸在不同区位间的差异达到极显著水平;③丙二酸、柠檬酸含量与分切区位(HN-1→HN-10)呈极显著负相关关系,草酸与分切区位呈极显著正相关关系,从叶尖到叶基,草酸含量呈逐渐增加的抛物线型变化,丙二酸和柠檬酸含量均呈逐渐降低的线性变化;④可将不同区位聚为两段,第一段(HN-1~HN-7)非挥发性有机酸含量为124.68 mg/g,第二段(HN-8~HN-10)含量为123.15 mg/g;⑤两段式分切烟叶样品的感官评吸结果为第一段(43.19分)>整片(42.08分)>第二段(41.04分),且第一段的得分显著高于整片和第二段,说明切除叶基3/10的烟叶有望作为高端原料的替代。

Abstract: In order to further explore the chemical component basis of cutting and machining the flue-cured tobacco leaf, this paper collected Henan robust flavor style flue-cured tobacco leaves as materials, which were cut into 10 sections (HN-1~HN-10), to study the changes of non-volatile organic acid contents in different cutting zone bits by one-way ANOVA and correlate and regression analysis; and conducted clusterring analysis and sensory evaluation of different sections based on non-volatile organic acid contents. The results indicated that: ① The average total content of non-volatile organic acid at different section were 124.22 mg/g, variation was from 41.70 mg/g to 193.40 mg/g, and average contents of each component showed as malic acid(89.38 mg/g)> oxalic acid(18.07 mg/g)> citric acid(13.48 mg/g)>malonic acid(3.13 mg/g)> succinic acid(0.17 mg/g). ② The contents of oxalic acid and malonic acid among different sections had extremely significant differences. ③ The contents of malonic acid and citric acid (HN-1→HN-10)had extremely significant negatively correlation with cutting sections, and oxalic acid was positively correlated with the section location. Its content presented a gradual increase in the number of parabolic changes. The contents of malonic acid and citric acid presented a gradual decrease linear change. ④ The robust flavor style flue-cured tobacco leaf could be cut into 2 sections, the contents of total non-volatile organic acid at the first section (HN-1~HN-7) were 124.68 mg/g, and that of the second section (HN-8~HN-10) were 123.15 mg/g. ⑤ The score of sensory evaluation showed that the first section(43.19)> full leaf(42.08)> the second section(41.04), and the score of the first section was obviously higher than those of the full leaf and second section, indicating the tobacco leaf cut off 3/10 leaf base could replace the high-end material.
