1、不同香型烤煙表面顏色特征分析摘要:為揭示不同香型烤煙表面顏色特征,采用L*a*b*C*顏色空間表征方法對14個省份三種香型烤煙不同部位煙葉表面顏色進行量化分析。結(jié)果表明:①煙葉表面顏色紅度講在濃香型和中間香型烤煙中變異程度較大,中間香型烤煙表面顏色的飽和度C*變化幅度大于濃香型和清香型烤煙。②中間香型烤煙表面顏色的明度L*最大,在中部葉和上部葉顯著高于清香型烤煙;清香型烤煙下部葉表面顏色的紅度a*顯著高于濃香型和中間香型烤煙。顏色飽和度C*在不同香型烤煙間不存在顯著性差異。③同一香型烤煙表面顏色均呈現(xiàn)下部葉的明度U最高,上部葉的最低,且在不同部位間存在顯著性差異,同時,同一香型
2、烤煙表面顏色的紅度a*均表現(xiàn)為上部葉最高,下部葉最低。④濃香型烤煙表面顏色的紅度a*與黃度b*、顏色飽和度C*呈極顯著負相關(guān),而清香型和中間香型的相關(guān)性都很小。本文采集自網(wǎng)絡(luò),本站發(fā)布的論文均是優(yōu)質(zhì)論文,供學習和研究使用,文中立場與本網(wǎng)站無關(guān),版權(quán)和著作權(quán)歸原作者所有,如有不愿意被轉(zhuǎn)載的情況,請通知我們刪除己轉(zhuǎn)載的信息,如果需要分享,請保留本段說明。關(guān)鍵詞:烤煙;香型;表面顏色特征中圖分類號:S572.01文獻標識號:A文章編號:1001-4942(2017)07-0034-04AbstractToexplorethesurfacecolorcharacteristicsofd
