由表 2 可知,在 300 ℃下,由于裂解温度相对 戊酮天然存在于烤烟烟叶、烟气中,具有芳香气味。
较低,产物组分较少,裂解产物中含量最高的组分 呋喃酮具有强烈的焙烤焦糖香、果香和菠萝样香气,
为丙酮(3.64 min),其次为 1, 6-脱水葡萄糖 广泛用作食品、烟草等的增香剂。从 Py-GC-MS 分
(23.52 min),未检测到麦芽酚的生成。随着温度 析结果来看, 麦芽酚糖苷受热能够裂解产生许多香

900 ℃下的裂解产物主要是麦芽酚,归一化质量分 2.4 感官评吸
数分别为 83.04%和 74.22%。除此之外,还有少量 添加麦芽酚和麦芽酚糖苷的卷烟评吸结果如表
的 4-羟基-4-甲基-2-戊酮和呋喃酮。4-羟基-4-甲基-2- 3 所示。

样品 光泽 香气 谐调 杂气 刺激性 余味
空白对照 光泽油润 香气淡薄、较粗糙 尚谐调 略有杂气 较有刺激 尚净尚舒适
加麦芽酚 光泽油润 香气充足、稍粗糙 谐调 无杂气 略有刺激 较净较舒适,前半段香气丰满,后半段香气不足
加麦芽酚糖苷 光泽油润 香气丰满、细腻 谐调 无杂气 无刺激 纯净舒适,前后香气差异不明显
