不同素质鲜烟的烘烤特性及工艺优化研究OA

To improve the curing quality of fresh tobacco leaves with different qualities,this study took the middle leaves of'Yunyan 87'as the material and set three treatments(M1,M2,M3)according to the maturity gradient.Curing characteristics were determined through dark box tests,and three curing process tests with different yellowing rates(T1:fast,T2:normal,T3:slow)were designed to systematically evaluate the economic traits,appearance quality and sensory quality of the cured tobacco leaves.The results showed that treatment M2 exhibited coordinated curing characteristics.When the T2 or T3 process was adopted,it had a high proportion of high-grade tobacco,a high total appearance score and outstanding sensory quality,which could improve aroma quantity and color score.Among them,this treatment achieved the highest total scores for appearance quality and sensory quality when the T3 process was adopted.Treatment M3 had good ease of curing but poor curing tolerance,and the T1 process significantly improved tobacco quality and average price,as well as enhanced oil content and color intensity.Treatment M1 possessed excellent curing tolerance.The T3 process helped improve tobacco quality,while the T1 process was conducive to ensuring the average price.In conclusion,to improve the quality of tobacco leaves,it is recommended to adopt the T3 process for treatments M1 and M2,and the T1 process for treatment M3.
