Preparation and Quantification of Reference Samples for Tobacco Stiffness
In order to explore the stiffness gradient of tobacco from a quantitative and qualitative perspective,the evaluation teams were established to screen and group samples from Yunnan production areas.The evaluation team had divided 7 gradients.Conducted gradient research on reference sample settings through inspection and analysis,and explored the correlation between correspond.The results indicated that the gradient of the stiffness reference sample was non overlapped and easy to distinguish.The threshold range of each gradient value was cleared and the difference was significant.The correlation between stiffness and color parameters had reached a significant level or above.The correlation between stiffness and physical property indicators had reached a highly significant level.To sum up,the preparation of reference samples can be used to guide tobacco production.Quantitative research on stiffness provides a reference for digital grading of tobacco.
