摘要:

为明晰不同烘烤工艺在热泵密集烤房烘烤过程中的烟叶水分和物质动态变化,以‘云烟87’中部叶为试验材料,研究稳温降湿和四步式烘烤工艺在热泵密集烘烤过程中的烟叶水分、色素、淀粉和还原糖含量动态变化及其相似性。结果表明:(1)稳温降湿烘烤工艺在黄片前期烟叶含水率高于四步式烘烤工艺。(2)稳温降湿烘烤工艺在黄片前期烟叶的叶绿素a、叶绿素b高于四步式烘烤工艺,但烘烤的中、后期低于四步式烘烤工艺。(3)稳温降湿烘烤工艺的烟叶类胡萝卜素和淀粉含量低于四步式烘烤工艺,但还原糖含量高于四步式烘烤工艺。(4)不同物质在2种烘烤工艺中的动态变化相似性排序为水分>叶绿素a>淀粉>叶绿素b>还原糖>类胡萝卜素。烘烤过程中物质动态变化可以分为3类,类型Ⅰ包括水分、叶绿素a、叶绿素b、淀粉,2种烘烤工艺的差异主要发生在变黄期;类型Ⅱ为还原糖,2种烘烤工艺的差异主要发生在定色期和干筋期;类型Ⅲ为类胡萝卜素,2种烘烤工艺在整个烘烤过程均存在较大差异。

Abstract:

In order to clarify the dynamic changes of moisture and substance in tobacco leaves during the heat pump intensive curing barn using different curing processes, the middle leaves of ‘Yunyan 87’ were used as experimental materials to study the dynamic changes and similarities of moisture, pigments, starch, and reducing sugar content during the steady temperature and humidity drop curing process and the four step curing processes in the heat pump intensive curing. The results showed that: (1) the moisture content of tobacco leaves in the early period of yellowing of the steady temperature and humidity drop curing process was higher than that of four step curing process. (2) The chlorophyll a and chlorophyll b of tobacco leaves in the early period of yellowing were higher than the four-step curing process, but lower than the four step curing process in the middle and late period of curing. (3) The contents of carotenoid and starch in tobacco leaves of the steady temperature and humidity drop curing process were lower than those of four step curing process, but the content of reducing sugar was higher than that of four step curing process. (4) The similarity of different substances in the two curing processes was ranked as follows: moisture> chlorophyll a> starch> chlorophyll b> reducing sugar> carotenoid. The dynamic changes of substances in the curing process can be divided into three categories. The first type includes moisture, chlorophyll a, chlorophyll b and starch, and the differences between the two curing processes mainly occur in the yellowing period. The second type is reducing sugar, and the difference between the two curing processes mainly occurs in the color-fixing period and the stem-drying period. The third type is carotenoid, two kinds of curing process have great differences during the whole curing process.

Key words: middle tobacco leaves, steady temperature and humidity drop curing process, four step curing process, chemical composition, dynamic change, similarity analysis
