| In this paper, the index including chemical compositions, sensory quality of the representative tobacco leaves samples was detected. The basic quality status of leaves was analyzed. The quality evaluation and formula information system of the "Pride" was constructed. The useful results included that:According to the present situation and development of the Pride's needs, the representative tobacco leaves samples were selected, sampling and sampling splitting were established; detection method of starch, pectin and cellulose has been improved.According to China's tobacco planting districts division, flue-cured tobacco of the selected southwest and southeast, mid-upper Yangtze river and Yellow & Huai river was described statistics,general characteristics including concentration trend and degree of variation of the chemical composition of materials for tobacco and the sensory quality index was accurately grasped.According to different growing areas, sensory quality of different parts (upper, middle and lower leaves), different quality (classy smoke, medium and low inferior tobacco leaves) and different years (2002-2006), sugar, alkali chlorine, alkali nitrogen, potassium, main flavoring components (polyphenols, acids, acidic aroma compositions and neutral aroma composition) of tobacco samples was done isometric bar charts, which changing trends was analyzed.The conventional chemical composition and sensory quality were corresponded analyzed, which fond the corresponding relations.The quality evaluation and formula information system of the "Pride" brand was constructed. Through the establishment of database, and analyze the application of data, the expert system realized the quality of raw tobacco spoiled "Pride" brand comprehensive evaluation, and will gradually realize the experience with the transformation formula, digital direction for the product research & maintenance, tobacco development planning, base construction and scientific aspects of raw materials procurement provides technical support. |
