Characteristics of Chemical Components and Evaluation of Usability of Nanjiang No.3 Flue-cured Tobacco Leaves from Kaiyang Tobacco Growing Area in Guizhou Province
摘要
Abstract
In order to investigate the characteristics of the main chemical components of flue-tobacco leaves in Kaiyang tobacco growing areas,78 samples of Nanjiang No.3 tobacco leaves with 3 grades( B2F,C3F,X2F) were collected from the five main tobacco-growing towns of Kaiyang and the contents of total sugar ,reducing sug-ar,nicotine,total nitrogen,potassium and chlorine were analyzed,and the usability was evaluated by means of fuzzy mathematics.The results showed that the ratio of nitrogen to nicotine in Nanjiang No.3 tobacco leaves of Kaiyang tobacco growing areas was high;the contents of other chemical components were appropriate and all within proper ranges and their coordination was good.The content of total sugar of B2F was high,however,the content of nicotine of X2F was low.The ratio of total sugar to nicotine was appropriate in B2F,however,that was high in C3F and X2F.The ratio of nitrogen to nicotine in C3F and X2F and the ratio of potassium to chlo-rine in all the three grades were high.There were differences in the contents of total sugar,reducing sugar,nico-tine,total nitrogen,the ratio of total sugar to nicotine,and the ratio of nitrogen to nicotine among tobacco leaves from different tobacco-growing towns.The average chemical components usability indexs ( CCUI ) of the flue-cured tobacco leaves from Kaiyang was 70.43.The comprehensive evaluation of chemical components was about 35.04%at the high leve1.CCUI values of the tobacco leaves from different tobacco-growing areas showed the trend of Zhaiji>Fengsan>Longgang>Machang>Huali.The comprehensive analysis of the chemical composition characteristics of the tobacco leaves provides theoretical basis for rational evaluation of the quality of flue-cured tobacco from Kaiyang tobacco leaves growing areas.关键词
