烟叶配比感官质量模型在叶组配方设计中的应用与分析

Application and Analysis of Tobacco Leafs Ratios-Sensory Quality Model in Tobacco Blend

摘要:

为减少人为主观对叶组配方的影响，增强叶组配方的客观性，以红大、K326、NC297和云87 4种烟叶的不同配比及相应感官得分出发，建立了烟叶配比值与感官得分之间的数学模型，筛选了对感官得分影响较大的烟叶配比组成，并对模型进行了分析和验证。结果表明：烟叶配比值与叶组感官得分之间具有较强的相关性，在一定条件下，烟叶配比值能较好地反映感官质量得分；通过模型分析，可以筛选出对复配烟叶感官影响较大的烟叶配比，有助于在叶组配方设计中正确控制不同烟叶的比例；结合等高线图分析，在一定条件下，可确定在不同烟叶配比条件下复配烟叶的感官得分范围；验证实验证明，通过烟叶配比感官得分模型调整烟叶配比比例，可提高叶组感官得分。因此，通过烟叶配比建立数学模型，可以从一定程度上指导叶组配方，减少人为影响因素。

Abstract:

For avoiding human influence on tobacco blend，enhancing objectivity of tobacco blend. A mathematical model was developed and validated between tobacco leafs ratio and the corresponding sensory quality based on four tobacco leafs of HongDa，K326，NC297 and Yun 87. The informative tobacco leafs ratios were screened and analyzed coupled with aroma components. Result showed that：the tobacco leafs ratios were correlative with sensory quality greatly，and the established model could reflect the correlation between tobacco leafs ratios and sensory quality；by model analysis，the informative tobacco leafs ratios could be screened，which is beneficial to quantity and ratios control of tobacco leaf in tobacco blend；the sensory quality of tobacco blend under different tobacco leafs ratios could be predicted conditionally by coupled with contour map analysis；by validation test，a better tobacco blend was get by through adjustment of the tobacco leafs ratios according to result of Tobacco Leafs Ratios -Sensory Quality Model. So by means of mathematical model，it is helpful for tobacco blend and free of human subjective factors.
