Quality Evaluation And Characteristic Analysis Of Burley Tobacco From Hubei

Burley tobacco is one of the important raw materials of hybrid cigarette, production of mixedcigarette largely affects the quality of the blended cigarette, thus improve its quality and practicabilityhas become a key task of leaf tobacco production in China.China Tobacco Shandong starting from theirown needs, in detail the specific analysis on the stability of the raw material quality, the various regionaltobacco appearance quality, chemical composition and sensory quality evaluation, and with the ChinaTobacco Shandong compared other burley tobacco raw material quality, to make the China TobaccoShandong "taishan" brand to provide theoretical basis and technical support.1.This article identified the tobacco appearance quality and chemical composition of the HubeiEnshi burley tobacco leaf, it typical appearance is: maturity is good, upper leaves identity is moderate,the lowest leaf identity is thin, color is light, loose structure. There is biggish variation of the mainchemical composition of Enshi burley tobacco leaf tobacco, chlorine content variation is larger, thenitrogen alkali ratio, nicotine, total nitrogen variation is small, overall high nicotine content.Whole onthe inner quality of aroma characteristics is significant, the aroma has good fullness and concentrationof aroma, mixed gas, at the same time show the momentum is larger, the resulting impact strength andexcitant strong, slightly less than flue gas balance, the flue gas is exquisite, the finish is clean and hasformed the unique qualities of the Enshi burley tobacco.2.Compares and analyses the quality of burley tobacco leaf tobacco in24different regions,nicotine content in the chemical composition is generally on the high side, the nicotine content isbetween2.4%and9.81%, total nitrogen content is between4.63%and5.84%, most of the samplechlorine content below1%, potassium content over3%, total potassium content is higher. Sensoryquality evaluation results show that the Enshi has obvious characteristics of burley tobacco scent, smellgood, good fullness and concentration, a mixed gas, impact larger, flue gas is exquisite and rich,aftertaste mostly feel bitter, the finish is good.3. Finally comparative analysis the quality of burley tobacco leaves of different years in2009-2013,the range of nicotine content is volatile, total nitrogen, total sugar, and potassium chloride content basicis appropriate, and more stable. Compared to the previous two years, in2013the sensory quality oftobacco leaves increased significantly, mainly reflected in the combustibility of the tobacco leavesobviously improved. According to the formula of cigarette demand in industrial production, thereasonable adjustment of burley tobacco proportion of each level in the formulation to achieve uniformas far as possible.
