包装材料对烤烟叶片自然醇化的影响

Effect of Packaging Materials on Aging of Flue-cured Tobacco Lamina

研究了塑料袋包装和牛皮纸包装对福建S04-98片烟自然醇化的影响。试验结果表明,在外观质量方面,采用牛皮纸包装优于塑料袋包装;在片烟化学成分方面,采用塑料袋包装的片烟还原糖含量下降的幅度较大,烟碱、挥发碱含量下降的幅度较小,挥发酸含量的增幅较大;而采用牛皮纸包装的片烟还原糖含量下降的幅度较小,烟碱、挥发碱含量下降的幅度较大,挥发酸的增幅较小;两种包装材料对醇化过程中片烟的pH值影响不大;在吸味品质方面,采用牛皮纸包装的片烟质量好于用塑料袋包装的片烟质量。

Effects of packaging materials, plastic bag and kraft paper, on aging of Fujian S04-98 flue-cured tobacco lamina were studied. The results showed that: 1) the appearance of the lamina packed with kraft paper was better than that with plastic bag; 2) in the lamina packed with plastic bag, the content of reducing sugar was significantly reduced, the contents of nicotine and total volatile base were slightly decreased, while the content of total volatile acid was considerably increased; 3) the changes of these chemical components in the lamina packed with kraft paper were contrary to those packed with plastic bag; 4) the pH values of the laminas were rarely affected by packaging materials during aging process; 5) the smoking quality of the lamina packed with kraft paper was better than that packed with plastic bag.
