Improvement on Smoking Quality of Tobacco Scraps with Microorganism Strain Yu-1

Sraps of low grade flue-cured tobacco were inoculated with the strain Yu-1 of microorganism isolated from high grade flue-cured tobacco and fermented at 28℃ for 6 days. The content of chemical components in the scraps after and before fermentation was determined. The results showed that the content of soluble reducing sugar decreased remarkably and the acidic value increased after the fermentation, some volatile organic acids were produced. The extract from the fermented scraps was added into cigarette tobacco as a casing. It was found that the irritation of cigarette smoke was reduced and smoking taste was improved significantly.
