Effects of Different Modifications on the Quality of Sun-dried Yellow Tobacco Leaves
[Objective]To improve the overall moderation efficiency of the sunbaked yellow tobacco moderation sheds in order to achieve high-er quality sunbaked yellow tobacco production.[Method]In this study,different modifications were explored through a systematic experimental setup.By monitoring the light intensity and SPAD values during the modulation process,we compared the appearance quality and chemical composition of sunburnt yellow cigarettes of different modulation methods,aiming to select the most superior modulation method.[Result]Sun-burnt yellow tobacco modulation shed suitable modulation is the smoke folded longitudinal hanging,drying spacing of 20cm.This treatment re-ceived the strongest light intensity and the degradation trend of SPAD value was consistent with CK.Through this modulation,the appearance quality of sunburnt yellow tobacco showed loose leaf structure,good surface oiliness,better elasticity,and moderate identity;the color of to-bacco leaf was mainly distributed in the domain of positive yellow to golden yellow,with uniform chromaticity,glossy and plump,and the leaf surface contained less green.The chemical composition also showed a more desirable state,with relatively high contents of total sugar(18.8%),reducing sugar(14.9%)and potassium(1.85%),while the contents of chloride ions and nitrogen-alkali ratio were appropriate.[Conclusion]The results of this study provide a strong guidance for sunshine yellow tobacco modification,and provide a scientific basis for re-alizing efficient and high-quality sunshine yellow tobacco production.
