密集烘烤过程中烟叶颜色、形态和水分变化及相互关系
Changes of Color, Morphology and Moisture of Tobacco Leaves during Bulk Curing and Their Relationship
摘要
Abstract
The change characters of color indexes, morphology and moisture and their relationship were studied during bulk curing with the middle leaves of flue - cured tobacco of K326 as materials. The results indicated that color indexes of the front and the back of tobacco leaves showed the same changing trend during bulk curing, and it had big change range in the prior period and small changes range in later period during bulk curing, while that of the front side changed faster. Color indexes of midribs changed latter than that of the blade. Thickness shrinkage changed greatly since the start of curing, while it had slowdown tendency in stem - drying stage. The rest of morphological characteristics indexes showed drastic change in middle stage and small change in prior and later period. The relative moisture content of blade, midribs and whole leaf was decreased during the curing, the water loss speed was low in the prior period, while it was fast in later period during bulk curing. There was significant or extremely significant correlation between redness degree of the front and the back of leaf and midribs and indexes of shrinkage, crimp rate and moisture content. Significant or extremely significant correlation existed between lightness value of the back of leaf and shrinkage index and longitudinal crimp rate, between lightness value of the front of leaf and thickness crimp rate, between yellow degree value of midrib and the crosswise crimp rate and moisture content, respectively.关键词
