Study of Raw Materials Position in Design of Raw Tobacco Formula Module

PurposeTo reveal the relationship between the chemical composition of raw tobacco formulation modules and single-grade tobacco raw materials, and to study the feasibility of utilizing chemical composition of tobacco leaf as the primary foundation for the modular formulation of raw tobacco, which could provide a theoretical foundation for optimizing the design of raw tobacco formulation modules.

MethodsBy using of fuzzy comprehensive evaluation method, 21 single-grade tobacco leaves from the same production area were classified for similarity, where the chemical composition of two raw tobacco modules from the region in Yunnan Province of China Tobacco Henan Industrial Co. Ltd., adopted as the benchmark. Specifically, the results were verified by sensory quality indicators.

ResultsGrounded on the classification criterion, the number of high, medium and low target raw materials in the two considered raw tobacco formulation modules were 4, 5, 12 and 3, 9, 9, respectively. The aggregate results of chemical indicators assessment for the 21 single-grade tobacco leaves were 90.48% and 76.19% congruent with the sensory quality classification.

ConclusionTargeting the chemical composition of the original tobacco formulation module permits a relatively precise classification of similarities between single grades of tobacco from the same production region. This study is highly applicable for rapid determination of target ingredients for raw flue-cured tobacco module design.
