摘要:

为明确打叶复烤关键工艺温度对烟叶化学成分的调控规律,提升烤后烟叶化学协调性与工业可用性,本研究以5个清香型烤烟模块多等级烟叶为原料,在云南文山复烤厂基于均匀设计法开展复烤加工试验,结合线性回归与冗余分析,探究回潮、干燥、冷却等工艺段温度参数与烤后烟叶总糖、总氮、糖碱比等核心化学指标的相关性。结果表明,一润热风温度、回潮一区温度通过促进淀粉降解显著提升总糖(相关性系数0.650)和还原糖(相关性系数0.561);回潮二区温度正向调控氮碱比(相关性系数0.512)、钾氯比(相关性系数0.359),冷却区温度显著降低总氮含量(相关性系数-0.708)。干燥一区温度对糖碱比具有双向调节作用(相关性系数0.553)。研究认为,一润热风温度、回潮一区温度、干燥一区温度、干燥三区温度、回潮二区温度、冷却温度是影响烟叶化学成分协调性和综合品质的重要工艺指标。研究提出,适当降低一润热风与回潮一区温度、提升回潮二区与冷却区温度,可有效优化烟叶化学品质。

Abstract:

Based on the uniform design system, the influence of the key process temperature of threshing and redrying on the chemical composition of tobacco leaves was analyzed, and the process optimization control strategy was established to provide a theoretical basis for improving the chemical coordination and industrial availability of flue-cured tobacco leaves. The uniform design method was used to carry out the redrying processing test in Wenshan redrying plant, and multi-grade tobacco leaves with five fragrant flue-cured tobacco modules were used as raw materials. Combined with linear regression and redundancy analysis, the correlation between temperature parameters of moisture regain, drying and other process sections and chemical indexes such as total sugar, total nitrogen and sugar-alkali ratio after baking was explored. It was found that the temperature of the first moistening hot air and the temperature of the first moisture regain zone significantly increased the total sugar (correlation coefficient 0.650) and reducing sugar (correlation coefficient 0.561) by promoting starch degradation. The temperature of the second resurgence zone positively regulated the ratio of nitrogen to alkali (correlation coefficient 0.512) and the ratio of potassium to chlorine (correlation coefficient 0.359), and the temperature of the cooling zone significantly reduced the total nitrogen content (correlation coefficient -0.708). The temperature of the first drying zone had a two-way adjustment effect on the ratio of sugar to alkali (correlation coefficient 0.553). The temperature of the first moistening hot air, the temperature of the first resurgence zone, the temperature of the first drying zone, the temperature of the third drying zone, the temperature of the second resurgence zone and the cooling temperature are important process indexes affecting the coordination of chemical components and comprehensive quality of tobacco leaves.
