甘油对不同类型烟草颗粒热解及香味释放特性的影响OA
Effects of glycerol on the pyrolysis and aroma release characteristics of different types of tobacco particles
分别采用热重分析方法和自建程序控温加热平台耦联烟气捕集装置研究甘油对不同类型烟草颗粒的热解特性及各类香味成分释放行为的影响.结果表明:1)4种不同类型烟草颗粒的热失重过程均可分为3个阶段,即脱水阶段(阶段Ⅰ)、脱挥发分阶段(阶段Ⅱ)、半纤维素和纤维素热解阶段(阶段Ⅲ);甘油在不同程度上提高了烟草颗粒在阶段Ⅱ的失重率以及最大失重速率,其中,甘油对雪茄烟颗粒的影响最显著,同时,甘油降低了阶段Ⅲ的失重率及最大失重速率,表明甘油与不同类型烟草颗粒间的相互作用存在差异.2)不同类型烟草颗粒的中性、酸性和酚类及碱性香味成分释放总量存在差异,未施加甘油的烤烟、香料烟、白肋烟、雪茄烟的中性香味成分释放总量依次降低,香料烟、雪茄烟、烤烟、白肋烟的酸性香味成分和酚类物质释放总量依次降低,白肋烟、雪茄烟、烤烟、香料烟的碱性香味成分释放总量依次降低.3)甘油在不同程度上提高了烟草颗粒各类香味成分的释放总量,中性香味成分释放总量提升幅度为44.07%~77.70%,酸性香味成分和酚类物质释放总量提升幅度为29.34%~53.32%,碱性香味成分释放总量提升幅度为7.49%~84.60%.甘油对不同类型烟草颗粒的热失重和香味释放特性影响程度不一,但整体均能够提升各类香味成分在加热状态下的释放总量.
To investigate the effects of glycerol on the pyrolysis characteristics and the release behavior of aroma components from different types of tobacco particles under heating conditions,thermogravimetric analysis and a self-built temperature-programmed heating platform coupled with a flue gas capture device were employed.The results were shown as follows.1)The thermogravimetric process of four different types of tobacco particles could be divided into three stages,i.e.,dehydration stage(stage Ⅰ),devolatilization stage(stage Ⅱ)and hemicellulose and cellulose pyrolysis stage(stage Ⅲ).Glycerol increased the weight loss rate and the maximum weight loss rate of tobacco particles in stage II to varying degrees,with the most significant effect observed in cigar tobacco particles.Meanwhile,glycerol reduced the weight loss rate and the maximum weight loss rate in stage III,indicating differences in the interaction between glycerol and different types of tobacco particles.2)There were differences in the total release amounts of neutral,acidic,phenolic,and alkaline aroma components among different types of tobacco particles.For tobacco particles without glycerol,the total release amounts of neutral aroma components decreased in the order:flue-cured tobacco,oriental tobacco,burley tobacco,and cigar tobacco;the total release amounts of acidic aroma components and phenolic substances decreased in the order:oriental tobacco,cigar tobacco,flue-cured tobacco,and burley tobacco;the total release amounts of alkaline aroma components decreased in the order:burley tobacco,cigar tobacco,flue-cured tobacco,and oriental tobacco.3)Glycerol increased the total release amounts of various aroma components from tobacco particles to varying degrees.The increase in the release amount of neutral aroma components ranged from 44.07%to 77.70%,the total release amount of acidic aroma components and phenolic substances increased by 29.34%to 53.32%,and the release amount of alkaline aroma components increased by 7.49%to 84.60%.The effects of glycerol on the thermogravimetric and aroma release characteristics of different types of tobacco particles varied,but overall,glycerol enhanced the total release amounts of various aroma components under heating conditions.
