Research On Correlation Between Main Physical Factors And Sensory Property Of A Cigarette

Cigarette smoking resistance not only the size of the cigarette smoke chemical stability has an important impact,while the sensory quality of cigarettes is also a huge impact.In this paper,five physical indexes,such as circumference,weight,smoking resistance,total ventilation rate and filter ventilation rate,were measured,and the sensory quality of the cigarettes was evaluated including aroma,miscellaneous gas,irritation and aftertaste.The relationship between the physical properties of the cigarettes and the sensory quality was analyzed,and the relationship between the cigarette weight and the circumference was analyzed.By using statistical analysis methods,the physical parameters and sensory evaluation of cigarettes from the same batches of the same trademark were used as materials to analyze the relationship between cigarette weight,draw resistance,ventilation rate and sensory evaluation.Results indicated that the significant indices of physical parameters and sensory evaluation were cigarette weight,draw resistance,filter ventilation rate,total ventilation rate,aroma,off flavor,irritancy and after taste.Stepwise regression equations were built between aroma,irritancy and filter ventilation rate,total ventilation rate,respectively,So were between off flavor and cigarette weight,total ventilation rate,also between after taste and draw resistance,filter ventilation rate,total ventilation rate.All of the equations were significant at 5%level.The variation tendency was similar between aroma,after taste and irritancy,both increased first and then decreased with the increase of cigarette weight and total ventilation rate.However the variation tendency of off flavor increased with the increase of total ventilation rate and decreased with the increase of cigarette weight and draw resistance.Irritancy decreased with the increase of draw resistance.The value of aroma exhibited the highest when cigarette weight,draw resistance,total ventilation rate were 0.749-0.781 g/cig,996-1089 Pa/cig and 24.6-32.4%,respectively.Cigarette weight,cigarette circumference,cigarette smoking resistance is an important indicator of the quality of cigarettes,the three indicators are interrelated and influence each other.In order to find out the correlation degree among the three indexes,the cigarettes with the same cigarette weight,the circumference of different cigarettes and the circumference of the same cigarettes and the weight of different cigarettes were designed.The results showed that there was a negative correlation between cigarette smoking circumference and cigarette smoking resistance.
