The Effect of Harvest Maturity on the Industrial Availability of the Cutters of Flue-cured Tobacco CB-1
[Objective]In order to clarify the influence of harvest maturity on the industrial availability of the cutters of flue-cured tobacco CB-1.[Method]A comparative curing test on different harvest maturity of the cutters of CB-1 was conducted,to test and compare the quality traits of cured tobacco leaves in each treatment.[Result]The results show that,the appearance quality,grade structure and average price of to-bacco leaves of ripe treatment was the best,mature treatment was second,unripe treatment was worse,overmature treatment was the worst.The high-class tobacco proportion of ripe treatment(75.63%)was higher than mature treatment(67.69%)11.73%,higher than unripe treatment(63.92%)18.32%,higher than overmature treatment(12.38%)510.90%.The average price of ripe treatment(36.36 yuan/kg)was 3.18%higher than mature(35.24 yuan/kg),6.69%higher than unripe(34.08 yuan/kg),74.96%higher than overmature(20.78 yuan/kg).With increasing harvest maturity,the total sugar,reduced sugar content and the ratio of sugar/nicotine of cured tobacco leaves tend to be better,and the chemical composition is more coordinated.The total aroma composition decreased with the increasing harvest maturity,the total aroma com-position of unripe(598.75 μg/g)was 0.85%higher than mature(593.71 μg/g),10.77%higher than ripe(540.53 μg/g),and 51.82%high-er than overmature(394.39 μg/g).With increasing harvest maturity,the ratio of damascenone which contributes the most to the fresh-aroma type style,and solanone which contributes the most to the full-aroma style,showed a significantly decreased trend,unripe(7.83)was highest,mature was second(6.18),ripe was third(4.96),overripe(3.90)was lowest.It means that the fresh-aroma style was significantly weakened.[Conclusion]In general,the ripe tobacco leaves have the best quality,industrial availability and economic benefits,and mature was second,and unripe and overripe were inferior.The ripe and mature are the appropriate harvest maturity standard in the cutters of CB-1.
