Abstract

Aroma style is a complex but critical sensory indicator of flue-cured tobacco. Near infrared spectroscopy was used to investigate the aroma style of flue-cured tobacco. A model screening-sensory validation strategy is herein proposed to overcome obstacles such as the subjectivity of sensory evaluation. Samples with exemplary styles and consistent opinion from a panel were selected as typical samples. Only typical samples were used for modeling. Other samples (atypical samples) were predicted through the proposed model. With references to sensory evaluation, the predictive accuracy reached to 100 and 79.0% for typical and atypical samples, respectively. This method provided a new perspective to evaluate the aroma styles of flue-cured tobacco by a combination of sensory evaluation and chemical analysis.
