不同产区陈化香料烟中部和上部烟叶的感官质量评价

Sensory evaluation of mid and top oriental tobacco leaves during aging in different areas

【目的】探讨不同产区陈化香料烟中、上部烟叶感官质量的变化规律。【方法】选取云南保山、湖北十堰、新疆石河子3个地区分别作为香料烟陈化的南部、中部、北部试点,对这3个产区的香料烟中、上部烟叶进行陈化,研究其感官质量的变化规律。【结果】不同试点陈化的各地区香料烟烟叶感官质量有所不同。香料烟烟叶在感官质量达到最佳状态时的平均评吸总分,以湖北十堰试点陈化的香料烟烟叶最高(85.13分),其次是云南保山试点(82.22分),新疆石河子试点的感官评吸总分最低(81分)。北部试点陈化的各地区香料烟烟叶均在27个月时感官质量达到最佳;除南部试点陈化的新疆石河子香料烟上部烟叶感官质量在18个月时达到峰值外,其余南部和中部试点陈化的各地区香料烟上、中部烟叶均在21个月或者24个月时评吸分值最高。【结论】随着陈化时间的延长,3个试点陈化的香料烟在陈化进程中的感官质量变化规律基本相同,呈现出感官质量持续快速上升期、最佳质量稳定期和感官质量回落期3个阶段,但不同试点、不同等级烟叶的变化幅度及达到最佳陈化质量的时间不同。

The objective of the present study was to discuss the changing laws of the sensory qualities during cutter and top oriental tobacco aging in different climate areas. [Method] Choosing Yunnan Baoshan, Hubei Shiyan and Sinkiang Shihezi as the south, middle and north experiment units, the changing laws of the sensory qualities during cutter and top oriental tobacco aging from these three areas were studied. [Result] Diversities of aging qualities existed under different climates. When the sensory evaluations achieved high-point,the average smoking scores of Hubei experimental unit were the highest, and smoking scores of Yunnan next,Sinkiang the lowest. Oriental tobacco of each area aged in north were the best in 27 months,and other upper and cutter oriental tobacco aged in north and middle experimental u- nits achieved peak values in 21 or 24 months expect for the Sinkiang Shihezi upper leaves aged in south which achieved peak values in 18 months. [Conclusion] Changing rules of smoking qualities in experimental units were almost the same in the course of aging, showing the sensory-quality-persisting-fast-raising- period,the best-quality-stable-period and the sensory-quality-descending-period, while changing scope and the best aging periods had distinction with different units and grades.
