药剂处理发酵法提高上部烟叶可用性初探

为了提高上部烟叶工业可用性，用A，C，D，E四种药剂处理烟叶，然后在温度35℃，相对湿度90%下发酵10d。对发酵后的烟叶进行评吸，并测定其中性香气成分、有机酸和相关化学成分含量。结果表明：（1）药剂C处理可以改善上部叶发酵品质。（2）C处理烟叶发酵后中性香气成分总量小于未发酵烟叶，其中糠醛、苯乙酮明显增加，而新植二烯含量降低较多。（3）C处理烟叶发酵后有机酸总量增加。（4）A、C、D、E四种药剂处理发酵后，烟叶总氮和烟碱降低较多，而还原糖和酚类降低较少。

Treat with Medicine in Fermentation to Improve the Usability of Upper Leaf Tobacco

Before fermentation, tobacco leaves were treated with four medicines of A, C, D and E to improve the usability of upper leaf. Ten days after fermenting at the conditions of 35℃ and the relative humidity of 90%, the neutral aroma components, the organic acids and the relative chemical components were measured in tobacco upper leaves. The results showed: (1) The medicine C could improve the upper leaves usability. (2)The amount of neutral aroma components of tobacco leaves treated with medicine C was less than that of the leaves without ferment. The content of furfural and hypnone rose in the leaves treated with medicine C, whereas the content of neophytadiend deccreased. (3)The amount of organic acids of leaves increased in the leaves treated with medicine C. (4) The reducing sugar and hydroxybenzene decreased little, however, the total nitrogen and nicotine decreased much in the fermentation leaves treated with the medicine of A, C, D or E.
