陈化期间空气湿度对山东和贵州C3F烟片质量的影响

Effects of Relative Humidity in Aging on C3F Lamina Quality of Shandong and Guizhou

摘要

摘要: 为了提高烤烟烟叶的陈化质量，研究了不同陈化期间空气湿度（52%，60%，68%）对山东、贵州C3F烟片物理指标、外观评价和化学成分变化的影响。结果表明，陈化9个月的山东、贵州C3F烟片的平衡含水率和填充值随着空气湿度的增大而升高。陈化时空气湿度大有利于山东C3F烟片淀粉、色素和多酚的降解，但是不利于总氮、烟碱的降解。陈化时空气湿度大有利于贵州C3F烟片总糖、还原糖和多酚的降解，也有利于烟叶pH的降低，但不利于烟碱、总氮和色素的降解。在外观评价方面，山东C3F烟片在60％空气湿度下最好，贵州C3F烟片在68％空气湿度下最好。

Abstract: Aiming to improve the aged quality of flue-cured tobacco, the changes of physical property, appearance and chemical components in different humidity conditions (T1=52%; T2=60%; T3=68% ) were studied with C3F lamina of Shandong and Guizhou Province. The results showed that, after nine months aging, the content of equilibrium moisture and the filling power of C3F lamina increased with the increasing relative humidity. Involving the laminas of Shandong, high relative humidity was favorable for degradation of starch, pigments and polyphenol, yet unfavorable for degradation of total nitrogen and nicotine. For the laminas of Guizhou, high relative humidity was favorable for degradation of total sugar, reducing sugar and polyphenol, and reducing of pH, whereas unfavorable for degradation of nicotine, total nitrogen and pigments. In terms of appearance evaluation, T2 and T3 demonstrated the best results of C3F lamina of Shandong and Guizhou, respectively.
