基于CRITIC赋权法的卷烟保润性能综合评价方法建立与应用
Establishment and application of a comprehensive method for evaluating cigarette moisture retention performance based on CRITIC weighting approach
摘要
Abstract
To evaluate the moisture retention performance of cigarettes more comprehensively and objectively,ten representative cigarette brands were selected for this research.Low-field nuclear magnetic resonance(LF-NMR)and gas chromatography(GC)were used to evaluate key indicators,such as the equilibrium moisture content and the drying rate constant(k value)of cut filler,the water-binding state and the total moisture content in the mainstream smoke.The CRITIC weighting approach was used to establish a comprehensive evaluation method for cigarette moisture retention performance,calculating objective weight coefficients for these indicators.The results showed that:1)There were significant differences in equilibrium moisture content among the cigarette brands(11.67%-13.17%),with moisture predominantly existing as strongly bound water(T21 peak integration area proportion>88%).The total moisture content in mainstream smoke ranged from 8.358 to 12.330 mg/g,while the drying rate constant varied between 0.289 5 and 0.376 1.2)The CRITIC-derived weight coefficients for the four indicators—equilibrium moisture content of cut filler,proportion of strongly bound water,total moisture in mainstream smoke and drying rate constant—were 0.168 4,0.214 7,0.308 9 and 0.308 1,respectively.3)A comprehensive evaluation of the moisture retention performance of different cigarettes revealed that their comprehensive moisture retention performance scores ranged from 61.78 to 97.90 points,with significant differences.In summary,a comprehensive evaluation method based on four cigarette indicators was established,which effectively reflected the objective differences between the moisture retention performance of different brands of cigarettes,and thus providing a useful approach for evaluating the moisture retention performance of cigarettes comprehensively.关键词
