【摘要】 试验采用二因素回归最优设计,研究了贵烟4号烘烤干筋恒定温度及持续时间对烤后烟叶香吃味评分及石油醚提取物含量的影响。结果表明:在干筋阶段当温度稳定在50℃-60℃持续时间5-20h时,烟叶香吃味评分和石油醚提取物含量表现出先增后降的抛物线曲线,最佳香吃味得分出现在温度54.3℃-57.0℃,持续时间为12.5-15.5h:最高石油醚提取物含量出现在温度54.3℃-56.3℃、持续时间5-12.5h时,二者具有较好的相关性。更多还原

【Abstract】 With the best regression of two factors of temperature and time, the experiment studied the relationship between leaf quality and change-less temperature and time in the stem-dring stage of flue-cured tobacco. The result indicated that the content of petroleum ether extract, aroma and taste of cured-leaf presented a trend of parabola curve, which increased to a higher level in the range from 54.3 to 57.0 degrees of temperature and 12.5 to 15.5 hours of the time to the aroma and taste score and 54.3 to 56.3 degrees of temperature and 5 to 12.5 hours of the time to the content of petroleum ether extract. The study also showed that it had a good relationship between the content of petroleum ether extract and aroma and taste.更多还原
