摘　　要：目的:探究有机酸对烟草及烟气pH的影响。方法:以34种单料烟和11种卷烟为研究对象,分别测定其非挥发性有机酸、烟草pH和卷烟主流烟气粒相物pH,采用灰色关联度分析、主成分分析对有机酸与pH进行相关性分析。结果:灰色关联度分析结果表明,草酸、软脂酸、苹果酸、油酸对单料烟烟草pH的影响程度相对较大;软脂酸、苹果酸、亚麻酸、草酸对卷烟烟草pH的影响程度相对较大;苹果酸、软脂酸、亚麻酸、草酸对卷烟主流烟气粒相物pH的影响程度相对较大。通过主成分分析,从单料烟有机酸中共提取出4个主成分,累计方差贡献率为76.66%,从卷烟有机酸中共提取出3个主成分,累计方差贡献率为78.46%。结论:苹果酸、草酸对单料烟烟草pH的影响程度较大,苹果酸、软脂酸对卷烟烟草pH、主流烟气粒相物pH的影响程度较大。Objective: To explore the effects of organic acids on tobacco pH and flue gas pH. Methods: 34 kinds of single-grade tobacco and 11 kinds of finished cigarettes were taken as the research objects, and their non-volatile organic acids, tobacco pH, and the pH of mainstream smoke total particulate matter were measured respectively. Grey correlation analysis and principal component analysis were used to analyze the correlation between organic acids and pH. Results: The results of grey correlation analysis show that oxalic acid, palmitic acid, malic acid and oleic acid have a relatively large influence on the pH of single-grade tobacco;Palmitic acid, malic acid, linolenic acid and oxalic acid have a relatively large impact on the pH of cigarette cut tobacco;Malic acid, palmitic acid, linolenic acid and oxalic acid have relatively large effects on the pH of mainstream smoke total particulate matter of the cigarettes. Conclusion: Comprehensive analysis shows that malic acid and oxalic acid have a greater influence on the pH of single-grade tobacco, and malic acid and palmitic acid have a greater influence on the pH of cigarette cut tobacco and the pH of mainstream smoke total particulate matter.
