In this thesis, through a representative sample of smoke in Sichuan and Chongqing Jiao sub-brand tobacco material chemical composition (including aroma components ) , sensory quality indicators for testing or smoking , analysis and evaluation of its basic quality status , built Pride brand quality assessment and formulation information systems, to obtain some valuable research results : present situation and development needs of the Pride brand tobacco samples selected representative sampling and , in the course of the study the improved method of detecting the relevant chemical components (starch , pectin and cellulose ) . In accordance with the division of the tobacco growing divisions , southwest , southeast, middle and upper reaches of the Yangtze River and the Huang-Huai four producing areas of flue-cured tobacco samples selected in accordance with the , in the next three parts of its chemical composition and sensory quality of descriptive statistics , more accurate grasp of tobacco raw material chemical composition and sensory quality indicators of the general characteristics ( central tendency , the degree of variation ) . Sugar producing areas in different parts (upper , middle and lower leaves ) , different quality grades ( fine smoke , medium smoke and low inferior smoke ) , different years ( 2002 - 2006) tobacco samples nicotine , nitrogen base ratio, the ratio of potassium chloride , the main flavor components ( polyphenols, polybasic acid , acidic flavor components and neutral flavor components ) and sensory quality , three - dimensional column chart , and trend analysis . Conventional flue - cured tobacco chemical composition and sensory quality of correspondence analysis to identify the corresponding relations . Constructed Jiaozi brand quality of raw materials evaluation and formulation information system . The system through the establishment of large amounts of data in the underlying database and database analysis , to achieve the Jiaozi brand tobacco material quality comprehensive evaluation, to promote changes in the direction of the human experience with digital recipe . Through the application of the system to provide technical support for product development and maintenance, tobacco development planning , base construction , the science of raw materials procurement and reserves .
