Effect of Rising Temperature Mode in Flue-curing Color Fixing Stage on Tobacco Quality and Neutral Aroma Constituent Content
摘要
Abstract
In order to confirm the optimal rising temperature mode in flue-curing color fixing stage,and further to optimize the bulk curing process and improve the quality of flue-cured tobacco, two different rising temperature modes(treatment I :1 ℃ every 4 hours during in 38 - 42 ℃ period,1 ℃ every 3 hours during 42 - 46 ℃ period,1 ℃ every 2 hours during 46 - 50 ℃ period, 1 ℃ every hour during 50-54 ℃ period; treatment Ⅱ :1 ℃ every (1 - 3) hours during 38 - 42 ℃ , 42 - 46 ℃ ,46 - 50 ℃ and 50 - 54 ℃ period) in co-lor fixing stage were set to study their effect on economic benefits,appearance quality,main content of chemical composition,smoking quality and content of neutral volatile aromatic constituents of flue-cured tobacco Zhongyan 100. The results showed that, compared with treatment Ⅱ , economic benefits in treatment Iwere better. Meanwhile, its coal consumption decreased, high class leaf proportion increased, and average price and production value raised 0. 15 yuan/kg and 318 yuan/ha, respectively. Moreover, oil composition, color and variegation of flue-cured leaf were optimized. In the middle and upper tobacco leaf, total sugar and reducing sugar increased 0. 82, 0. 33 percent points and 0.66,0.22 percent points, while nicotine and starch decreased 0.11,0. 09 percent points and 0. 54,1. 03 percent points,respectively,comprehensively indicating a more coordinate chemical composition. Besides offensive smell was reduced, total score of smoking quality was increased and quantity of aroma was improved. The content of neophytadiene and volatile matter enhanced 8. 20% and 5. 68% respectively in the middle leaf,arid in the meanwhile,the ratio of neophytadiene to volatile matter and content of analytes were improved in the middle and upper leaf. However,the contents of neophytadiene, volatile matter,dissolutions of carotene and aromatic amino acid,and products of Mail-lard reaction were higher in flue-cured tobacco leaf of treatment Ⅱ. Above all,economic efficiency and leaf quality were improved by rising temperature mode of treatment I, which was worth to spread in bulk curing in Henan province.关键词
