贵州中烟工业有限责任公司项目“烟叶醇化过程质量研究”（12121）；

本校为第一机构

为探究不同产地不同部位片烟在醇化过程中抗氧化物质的变化规律,对贵州中烟6个原料基地上中2个部位片烟的类胡萝卜素、多酚和维生素C含量进行了分析.结果表明,在醇化过程中,抗氧化物质主要以氧化分解为主,类胡萝卜素、多酚和维生素C含量呈现下降趋势,类胡萝卜素的分解主要发生在12~21个月期间,而多酚和维生素C的分解主要发生在0~12个月,且两者含量呈极显著正线性相关关系.片烟叶黄素和 β-胡萝卜素含量在醇化12~18和18~21个月期间均以四川凉山、福建三明和贵州遵义降解速度较快;绿原酸、芸香苷和维生素C含量在醇化0~6个月期间均以云南保山、福建三明和四川凉山降解速度较快,在醇化6~18个月期间均...

The contents of carotenoid, polyphenol and vitamin C of flue-cured tobacco strips of upper and middle leaves from six raw material bases, China Tobacco Guizhou Industrial Co., Ltd, were analyzed, to study the trend of antioxidant substances of different producing areas and leaf positions during the process of aging. The results showed that, during aging, the decomposition of antioxidant substances was mainly oxidative decomposition, and the contents of carotenoids, polyphenol and vitamin C showed trends of declining. Carotenoids decomposition o...
