Abstract:

In order to further improve the quality of burley tobacco drying, the effects of different mesh shade net shading treatments on the drying cycle, intrinsic chemical composition of tobacco leaves, neutral aromatic substances and sensory quality of burley tobacco were analyzed for the simple arched drying shed facility in Enshi tobacco area. The results showed that covering a shade net with a certain mesh size could improve the temperature and humidity of the drying process, prolong the drying cycle of tobacco leaves, and significantly increase the contents of total sugar, nicotine, potassium and total nitrogen in the middle and upper leaves. In terms of improving the quality and flavor of burley tobacco, covering 60 mesh shade nets was the best. The highest contents of new phytodiene, plastid pigment degradation products (except neophytodiene) and phenylalanine in the middle leaf were 1 638.95, 194.27 and 56.78 μg·g-1, and the highest contents of new phytodiene, plastid pigment degradation products (except neophytodiene) and phenylalanine in the upper leaf were 1 554.29, 194.89 and 68.66 μg·g-1, respectively. 60 mesh shade net is suitable for Enshi burley tobacco production area.
