摘要
采用正交实验设计的方法研究了B4F烤烟烟叶中的重要致香成分——西柏烷类降解产物、类胡萝卜素降解产物在烟叶复烤过程中的变化。结果表明:①复烤过程中,烟叶二氢猕猴桃内酯含量受冷却区温度、干燥区网面风速的影响显著;巨豆三烯酮受冷却区温度的影响显著;茄酮受冷却区含水率的影响显著;降茄二酮受冷却区含水率、温度的影响显著。②复烤过程中,β-大马酮、β-二氢大马酮、β-紫罗兰酮、异佛尔酮和氧化异佛尔酮的含量未发生显著性变化。③采用冷却区含水率13%,冷却区温度40℃,干燥区网面风速0.7 m/s的复烤工艺参数,将有利于西柏烷类降解产物、类胡萝卜素降解产物的积累,可提升烟叶内在品质,有利于节能降耗。
The changes of degradation products of carotenoids and cembranoids in B4F flue-cured tobacco during redrying were studied with orthogonal experimental design. The results showed that： 1） The content of dihydroactinidiolide was remarkably affected by the temperature in cooling section and vertical air velocity in drying section; megastigmatrienone and solanone were remarkably affected by the temperature and moisture content in cooling section, respectively; norsolanadione was remarkably affected by the moisture content and temperature in cooling section. 2） The contents of β-damascenone, β-damascone, β-ionone, isophorone and isophorone oxide did not change remarkably. 3） Redrying with the following parameters： moisture content in cooling section 13%, temperature in cooling section 40 ℃, vertical air velocity in drying section 0.7 m/s, would be helpful to the accumulation of degradation products of carotenoids and cembranoids, the improvement of tobacco quality and the decrease of tobacco waste and energy consumption.
