Embodiment 1

[0066] Weigh a certain amount of tobacco leaf shredded tobacco sample m 1 Put it in the solvent cup of the Soxhlet extractor, add distilled water according to the ratio of solid to liquid at 1:25, set the cycle number of the Soxhlet extractor to 10 times, the extraction temperature to 100°C±1°C, and the cooling water circulation device to 2°C. Extraction, the extraction time is 2.3h, uncap the weighing bottle and bottle cap and put it in the oven for 3h, add the cap and take out the weighing bottle, cool to room temperature, weigh the mass of the dry weighing bottle and bottle cap m 0 After the extraction, take out the sample, transfer it to a dried weighing bottle, put it in an oven, and bake it at 105°C±1°C until it reaches a constant weight, then cover it and take it out of the weighing bottle, cool it to room temperature, and cover it. Weigh the lid and weigh the total mass of the bottle and sample after drying m 2 According to YC / T31, the water content of the tobacco sam...

Abstract

The invention discloses a characterization method for the intrinsic sensory quality of tobacco leaf raw materials, belonging to the technical field of tobacco leaf quality evaluation research. The present invention uses the Soxhlet extraction method to accurately measure the hot water soluble content of tobacco leaf raw materials, the hot water soluble content has a strong correlation with the sensory score, and uses the decision tree method to establish the relationship between the tobacco leaf raw material sensory score and the hot water soluble content Regression equation, and then according to the established equation, the sensory quality of tobacco leaf raw materials can be characterized by the content of hot water soluble matter. The present invention predicts the sensory score through the hot water soluble matter content of the tobacco leaf raw material, the method is simple and easy to operate, the established characterization method is more objective, and has good guidance and practicability for tobacco leaf quality evaluation.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf quality evaluation research, and in particular relates to a characterization method for the intrinsic sensory quality of tobacco leaf raw materials. Background technique [0002] Tobacco leaves are the foundation of the cigarette industry. To stabilize and improve the quality of cigarette products and expand the market share of products, the tobacco leaves used in cigarettes are very important. The development of every high-quality cigarette is based on the stable supply of high-quality tobacco raw materials. Tobacco leaf quality is a comprehensive fuzzy concept that reflects and embodies the balance of essential traits of tobacco leaves. influences. Sensory quality is an important part of cigarette product quality and the foundation and core of product quality. It refers to the comprehensive perception of human body senses by the mainstream smoke produced during the burning of cigarettes, ...
