Preparation of Roxburgh Rose Extracts and Its Application in Flue cured Tobacco
[Objective]To study the effects of various factors on extracting of roxburgh rose with ethanol solution. [Method]Extracting time, ratio of material to liquid and extracting times were selected for single factor test and orthogonal test. [Result]The results showed that,the influence of the three factors on the amount of roxburgh rose extract was extracting times ratio of material to liquid extracting time. The optimized extracting conditions were obtained and verified. The roxburgh rose extract was analyzed by GC MS method,109 components were indentified. The roxburgh rose extract was also added into cigarettes for sensory evaluation. [Conclusion]It was found that the roxburgh rose extract obviously increased the sensory quality on the amount of aroma,coziness and after taste.
