Effect of Moistening Strength on Physical Structure and Sensory Characteristics of Tobacco Leaves
Orthogonal experiments were used to analyze the physical structure and sensory characteristics of tobacco leaves under different moistening strength.The results showed that the process parameters that affect the sensory quality evaluation after leaf wetting were hot air tem-perature,return air temperature and outlet moisture.When the raw material grade was FC2F,the hot air temperature was 105℃,the return air temperature was 37℃,and the outlet moisture was 18.5%,the color change of the tobacco leaves was within the range of seemingly deep-ening to slightly deepening,without any obvious deepening phenomenon,the physical and technological indicators were good,the large film ra-tio was greater than or equal to 85%,and the sensory quality of aroma characteristics,taste absorption characteristics,and other sensory quali-ties were the best,achieving the goal of aroma preservation processing.It can be seen that by adjusting the process parameters of the pre-treat-ment process to achieve flexible treatment,while ensuring the physical structure of tobacco leaves,maintaining the richness and concentration of tobacco aroma,improving the availability of tobacco leaf formula and expanding the use range of tobacco formula,providing high-quality raw materials for the development of cigarette brands,and also providing reference for the optimization of threshing and redrying process and the re-search on intelligent control of leaf moistening.
