Comparison of Composition and Contents of Chemical Component and Neutral Aroma Components in Different Types of Tobacco
摘要
Abstract
Contents of neutral aroma constituents and alkaloids were compared in 5 types of tobacco ( flue-cured ,burley, Oriental, Maryland and sun-cured)from Sichuan. Results showed that;The content of total and reducing sugar(28.36% ,24.52% )were the highest and total nitrogen lower in flue-cured,the contents of the total and reducing sugar in Oriental which had the least content of total nitrogen (1. 79% ) were less than the flue-cured and the sun/air-cured tobacco with higher nitrogen and less sugar. The content of nitrogen-nicotine ratio and sugar-nitrogen ratio in flue-cured tobacco was the most suitable and the ratio of potassium to chlorine of all different types of tobacco was greater than 4,meeting the characteristics of high-quality tobacco leaf. Classification contents of neutral aroma in Wanyuanwuyan were more higher than other kinds of sun-cured tobacco. Except sun-cured tobacco, the contents of products degraded by carotene and neophytadiene(63. 29 ,731. 92 μ/g) in flue-cured were more higher than other types of tobacco while the products of aromatic amino acid metabolism, the products degraded by cem-brane and the products of browning reaction were highest in Oriental. The contents of all kinds of aroma component in Maryland were closer to the burley but at a high level of solanone. The analysis can provide theoretical foundation for the prescription design of Tobacco Blend Grouping of Chinese Type Cigarette. Chemical components and neutral aroma components had abroad variations and the proportion of the groups with chemical components were also dissimilar in different types of tobacco which causing the major factors of the aroma style and smoking quality.关键词
