[Method] In Peng-shui county in Chongqing, tobacco variety K326 was chosen as test materials to conduct tobacco curing tests as per three techniques to analyze key components of raw tobacco, grade quality and evaluation quality. [Result] The content of starch in tobacco was reduced by Chinese tobacco curing-method for improving tobacco quality and fragrance, and the ratio of middle and high quality grade tobaccos improved by 1.8%-7.95%; average price increased by 1.64-3.21 yuan/kg; evaluation grade grew by 1.5-4.4. The technique is proved in enhancing tobacco fragrance quality and quantity as wel as improving and adjusting fragrance, taste and flavor. [Conclusion] Chinese (three-phase) tobacco curing technique improves tobacco quality and provides references for production demonstration areas of tobacco curing.展开更多

The results showed that for good appearance quality of cured tobacco, the loading density at 59.52 kg/m2 (4 000 kg/barn) was the best, fol owed by 66.96 kg/m2 (4 500 kg/barn) and 74.40 kg/m2 (5 000 kg/barn). As leaf loading density increased, the contents of leaf nicotine and total nitrogen increased, sugar content had smal changes, the ratio of sugar to nicotine decreased and tended to be balanced and the content of neutral aroma substances was decreasing, but the difference among treatments was not significant. With the increase of loading density, the sensory quality of cured leaf was better. When leaf loading density was 66.96 kg/m2 (4 500 kg/barn), apperance quality of cured leaf improved considerably, with prominent aro-ma. Therefore, the best loading density of tobacco leaf in cage clamp of bulk-curing barn would be 66.96 kg/m2 (4 500 kg/barn) .展开更多
