金莲花浸膏的热裂解行为及单料烟加香应用研究

Study on the Pyrolytic Behavior of the Extract of Trollius chinensis Bunge and Application of Unblended Cigarette Flavoring

摘要: 在模拟卷烟点燃过程条件下对金莲花浸膏进行了热裂解,以气相色谱-质谱法测定其在不同温度（300、600、900 ℃）下的裂解产物,并进行单料烟加香研究。结果表明,在300、600、900 ℃的金莲花浸膏热解产物中分别鉴定出28、29和31种成分,裂解产物主要为酸类、酯类、醇类、酚类、醛类和酮类等对烟草香味有利的香味物质。金莲花浸膏具有改善和修饰单料烟吸味、丰满烟气、减轻刺激性的作用。

Abstract: The extract of Trollius chinensis Bunge was pyrolyzed under simulated condition of process of smoking. Then the pyrolytic products were measured by Py-GC-MS under different temperatures of 300, 600 and 900 ℃, respectively, and the applications of the extracts in unblended cigarette flavoring were studied as well. The results showed that 28, 29 and 31 constituents were identified in the pyrolytic products at 300 ℃, 600 ℃, 900 ℃, respectively. Pyrolysis products were mainly acids, esters, alcohols, phenols, aldehydes and ketones, which were beneficial to the smell of tobacco flavor. The extract from Trollius chinensis Bunge was characterized by enhancing the aroma quality and volume of smoke, reducing irritancy and improving the aftertaste.
