Abstract
In order to explore the effect of one-time cutting and roasting of ‘Yunyan 87’ on its production and quality, in this paper, ‘Yunyan 87’ was conventionally picked and roasted. The stalk-cut of upper 4 ~ 6 pieces of leaves were roasted at one time, and the use of labor, coal, and appearance quality, chemical composition, evaluation quality and economic characters were compared and analyzed. The results show that the appearance quality of the cured tobacco leaf and smoking quality were improved by one-time cutting and baking method. The total sugar, reducing sugar, potassium, chlorine and ratio of alkali to sugar and two-sugar content of one-time cut and baked leaf were increased compared to conventional curing method. The one-time cut and baked leaves are with high degree of leaf maturity, rich in oil content, high chromaticity and identity thin, and enhanced industrial usability. The proportion of superior tobacco reached to 57.32%. The average purchase price increased by 0.87 yuan per kilogram. However, the leaves of one-time cutting and baking method required longer time for roasting, and turned to yellow slowly. The single leaf weight of tobacco leaves after roasting was also reduced, and costs of coal and labor increased, which led to an increase in baking cost of 0.46 yuan per kilogram higher than that of conventional curing processing.
