不同装烟方式对烤烟烘烤烟叶品质和安全性的影响
Effect of Different Loading Methods on the Tobacco Quality and Safety During Flue-Curing
摘要
Abstract
[Objective] In order to discuss the formation mechanism of flue-cured tobacco quality and further improve tobacco quality and tobacco safety,the curing effect under different loading methods (T1:natural ventilation type curing; T2:hanging-pole bulk curing; T3:sticking leave bulk curing which is a kind of loose leaves bulk curing while tobacco leaves are stuck by skewer) was studied.[Method] Changes of moisture,carotenoids and cuticular components content of tobacco leaves during flue-curing,and the difference of the main chemical composition,neutral aroma components,smoke harmful ingredients content and sensory quality of flue-cured tobacco leaves under different loading methods were studied.[Result] The results showed that T3 had a higher moisture content than T2 at 48-72 h (P＜ 0.05).In terms of plastid pigment,T3 decreasing range of β-carotene and lutein content were 62.91％ and 69.45％,higher than T1 (57.59％ and 65.19％) and T2 (57.59％ and 60.31％).T3 had a lower pigments content than T1 and T2 at the end of curing.In terms of cuticular components,T1 and T3 had a higher trichome exudates content than T2,and T1-T3 loss rate of trichome exudates were 8.82％,54.05％ and 10.52％,respectively.T3 had the highest alkanes content and its loss rate was 13.80％ while T2 had the lowest alkanes content and its loss rate was 58.91％.Compared with T1 and T2,T3 had the highest neutral aroma components content (1186.65 μg·g-1),a more coordinated chemical composition and higher score value (60.75 points) of sensory quality.In terms of smoke harmful ingredients content,the total carbonyl compound content of different treatments showed that T3 (1 034.08 μg·cig-1)＜T1 (1 144.76 μg·cig-1)＜T2 (1 251.19 μg·cig-1),and there was a significant difference between T1 and T2 (P＜ 0.05).The total smoke phenols content of tobacco leaves under different loading methods showed that T3 (149.93 μg·cig-1) ＜T2 (157.71 μg·cig-1)＜T1 (175.60 μg·cig-1).At the same time,T3 had the lowest content of crotonaldehyde,CO,and benzo[a]pyrene.Compared with T1,T2 and T3 had a lower content of HCN (P＜0.05).[Conclusion] Compared with T1 and T2,T3 had a slower dehydration speed of tobacco leaves during flue-curing,a lower carotenoid and smoke harmful ingredients content,and a higher cuticular components and neutral aroma components content,a more coordinated chemical composition and a higher score value of sensory quality of flue-cured tobacco leaves.Comprehensive evaluation of the flue-cured tobacco quality under different loading methods,T3 was the best.关键词
