Abstract
Minimization of tobacco-specific nitrosamines (TSNAs) is a focus for many involved in burley tobacco research and production. Environmental factors in curing barns during the 2-week physical transformation from yellowing to browning affect concentrations of TSNAs in cured tobacco. The objective of this study was to develop mathematical models for TSNA accumulation on the basis of temperature and relative humidity. Temperature and relative humidity were measured continuously in 20 burley tobacco barns located in Tennessee during the 2008 and 2009 growing seasons. The environmental data were analyzed by creating thresholds of temperature ( 70°F) and relative humidity (>80%, >85%, >90%). For each barn during weeks 3 through 5 of curing, total hours that temperature and relative humidity (RH) satisfied these thresholds were defined as Th 70, RHh>80, RHh>85, or RHh>90. From these threshold counts we developed various models on the basis of regression analysis. Models were linear, interaction, ...
期刊介绍：
Chinese Tobacco Science is an academic scientific journal (bimonthly) under the supervision of the Ministry of Agriculture and Rural Affairs of the People's Republic of China, and sponsored by the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences and the Qingzhou Tobacco Research Institute of China National Tobacco Corporation. It was founded in 1979 and is publicly distributed nationwide. The journal mainly publishes academic papers on scientific research results, new production technologies, and modern management in my country's tobacco science research and tobacco production technology. In addition, it also publishes forward-looking review articles in the field of tobacco research. There are columns such as tobacco genetics and breeding, cultivation technology, modulation and processing, physiology and biochemistry, plant protection, review or monograph, quality chemistry, etc.
