不同产区烤烟中质体色素及降解产物的研究

探索不同生态环境与烤烟中质体色素及其相关降解产物的关系，以及质体色素及其降解产物与烟草香型、香气质和香气量的关系，以我国不同生态条件的烤烟产区烟叶为材料，对烤烟样品中的叶绿素、类胡萝卜素及其相关降解产物的含量进行了分析。研究结果表明，云南、贵州、重庆等产区烤烟中的类胡萝卜素含量普遍高于东北和福建等烤烟产区；不同烤烟产区之间类胡萝卜素降解产物的含量存在很大差异；并且云南烤烟独特香气风格的形成与其烟叶中各种质体色素降解产物的协调性有关。

STUDY ON CHROMOPLAST PIGMENTS AND ITS DEGRADING PRODUCTS OF THE FLUE -CURED TOBACCO FROM DIFFERENT PRODUCTING REGINONS IN CHINA

In order to explore the relationship between the different ecology environments and the content of chromoplast pigments and their degrading products, as well as chromoplast pigments and their degrading products and aroma type, quality of aroma in the flue-cured tobacco,we analyze the content of chromoplast pigments and their degrading products of the flue-cured tobacco from the different flue-cured tobacco producting regions in china. The conclusion demonstrate that carotenoid content in the flue-cured tobacco of producing regions such as Yunnan , Guizhou and Chongqing universally is more than Northeast and Fujian. Carotenoid degrading products are quite different among the different flue-cured tobacco producing areas. The unique aroma style of flue-cured tobacco in Yunnan related with coordination of carotenoid degrading products
