摘要
将铁观音茶梗机械浆分别在300、600、900℃下进行热裂解,用气相色谱-质谱联用仪对其裂解产物挥发性成分进行定性分析和半定量分析,为铁观音茶梗在烟草薄片中的应用提供理论依据。结果表明,铁观音茶梗浆可裂解出大量的香味成分,其中包括多种构成铁观音茶独特茶香韵的主要成分。铁观音茶梗浆的裂解产物构成卷烟香味的同时也赋予了卷烟烟气独特的茶香韵,并能改善卷烟吸味,提升其抽吸品质。
Pulp of Tieguanyin tea stem was pyrolyzed at 300,600,900 ℃,respectively.The pyrolysis products were analyzed by GC-MS qualitatively and semi-quantitatively.This analysis provided a theoretical basis for the application of Tieguanyin tea stem pulp in tobacco sheet.The results showed that massive aroma components which included main components of the unique charm of Tieguanyin tea were pyrolyzed from Tieguanyin tea stem pulp.Consequently,pyrolysis products of Tieguanyin tea stem pulp constituted the cigarette fragrance,endowed unique charm of Tieguanyin tea to cigarette fragrance,and showed a more significantly active impact on cigarette quality taste in terms of aroma richness,irritation and comfortableness.
