Abstract: In order to improve the inner quality of cigarette and upgrade its utilization value, this experiment studied and analyzed the routine chemical components and content of neutral aroma substances in tobacco leaves using ordering cylinder and different recirculated air temperatures. The result showed that: ①  In terms of routine chemical components, two difference of sugar was high and ratio of potassium to chlorine and sugar-nicotine ratio were low, when recirculated air temperature was 57℃. The chlorine was high and ratio of potassium to chlorine and proportion of nitrogen to nicotine were low, when recirculated air temperature was 62℃. The chemical composition of recirculated air temperature 57℃ was more in line with the requirements of high quality tobacco leaves. ② In terms of neutral aroma substances, the total amount shown as: 57℃＞62℃＞52℃. Within certain scope, the bigger the aroma quantity, the more expression of aroma characteristics.  Different recirculated air temperatures had unanimous influence on routine chemical components and neutral aroma substances.

摘要： 为提高卷烟内在质量，提高烟叶的利用价值，利用松散回潮工序不同回风温度的试验，对烟叶常规化学成分与中性致香物质的含量进行了研究分析。结果表明：①对常规化学成分，回风温度52℃时的两糖差偏高，钾氯比和糖碱比偏低；回风温度62℃时的氯含量偏高，钾氯比和氮碱比偏低；回风温度57℃时的化学成分更符合优质烟叶的要求；②对中性致香成分，其总量表现为：57℃＞62℃＞52℃，一定范围内，香气量越大越有利于表现香气特征。不同回风温度对常规化学成分与中性致香物质的影响具有一致性。
