枫槭浸膏热裂解产物分析及其在卷烟中的应用
Pyrolysis analysis of maple concrete and its application in cigarette
-
摘要: 采用裂解-气相色谱-质谱联用(Py-GC-MS)模拟卷烟燃烧过程,将枫槭浸膏分别在不同温度(300℃,600℃,900℃)下进行热裂解,将热解产物直接引入气相色谱-质谱仪进行定性、定量分析,并进行卷烟加香实验.结果表明:枫槭浸膏裂解产物主要是醛类、酮类、酯类和杂环类物质,大多具有优雅的香味;随着裂解温度的升高,裂解产物变得较为复杂,这有助于提高卷烟香韵的丰富性.卷烟加香试验表明,枫槭浸膏在烟丝中的添加量宜控制在0.02%,可突出焦甜香韵和改善卷烟的抽吸品质.

Abstract: The pyrolysis of maple concrete was performed by an on-line pyrolysis gas chromatography/mass spectrometry (Py-GC-MS) for simulation cigarette combustion process.The maple concrete was pyrolyzed at different temperatures (300℃,600℃,900℃); the pyrolysis products were directly introduced into GC-MS to make,qualitative and quantative analysis and cigarette flavoring experiments were carried out.The analysis results showed that the main pyrolysis products are aldehydes,ketones,esters and heterocyclic substances at different temperature,most of which have elegance flavor.The pyrolytic compounds were more and more complex with the increase of temperature.The tobacco flavoring experiment showed that the maple concrete added in the tobacco at 0.02% was appropriate,imparting a sweet,caramelic flavor to the cigarette and improving cigarette sensory quality.-
