Description

Technical Field

[0001] The invention relates to the technical field of tobacco processing, and in particular to a method for improving the quality of tobacco leaves with a long inventory period and small grades. Background Art

[0002] In recent years, with the continuous adjustment of cigarette brand structure and the restrictions on tobacco leaf procurement by industrial enterprises, the inventory of raw materials of cigarette enterprises still has a contradiction that is not in line with the demand for high-end cigarettes. There are mainly two situations. One is that the inventory of tobacco leaves in a certain production area is high and the formula applicability is not high. The application ratio in the existing leaf group formula is low, resulting in a long inventory cycle; the other situation is that although the quality of the tobacco leaves themselves is good, due to the small inventory, in order to ensure the stability of the quality of cigarette products, small-grade tobacco leaves with low applicability in the formula are used. In short, the backlog of tobacco leaves that are not suitable for the formula of cigarette industrial enterprises not only occupies inventory and capital costs, but also continues to decompose and lose its tobacco leaf aroma substances as the storage time increases, resulting in a continuous decline in tobacco leaf quality.

[0003] In order to solve the problem of the applicability of the tobacco raw materials in storage, Zhao Sensen et al. (CN113180270A) of Henan Zhongyan disclosed a method for recycling the tobacco raw materials in storage, which is mainly achieved by classifying the tobacco raw materials in storage and carrying out their replacement application in the formula. However, the above existing technologies cannot achieve the coupling effect of tobacco raw materials with different quality characteristics in storage, and need to be improved. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a method for improving the quality of long-cycle and small-grade tobacco leaves in stock, which mainly uses the formula module method to design a formula module that includes both long-cycle tobacco leaves and small-grade tobacco leaves, and combines the application of flavor regulators to synergistically improve the availability of the module. The invention takes into account the combination of long-cycle tobacco leaves in stock and small-grade tobacco leaves, and provides a way to improve the resource utilization efficiency and use value of tobacco raw materials.

[0005] To achieve the above-mentioned purpose, the present invention provides a method for improving the quality of long-term and small-grade tobacco leaves in stock, characterized in that a formula module including long-term tobacco leaves and small-grade tobacco leaves is designed based on the sensory quality and chemical composition of the long-term tobacco leaves in stock and the small-grade tobacco leaves, and the module usability is improved by adding a flavor regulator. The specific method comprises the following steps:

[0006] 1) Sort out and compile statistics on tobacco leaf inventory information, and based on the current tobacco leaf usage in the formula structure, screen out long-cycle tobacco leaves with a small usage ratio in the formula and high inventory, and small-grade tobacco leaves with poor formula applicability due to small inventory.

[0007] 2) Conduct sensory style quality evaluation and chemical composition testing on the tobacco raw materials selected in the above step 1) to clarify the quality characteristics of tobacco leaves with long inventory cycles and small grades.

[0008] 3) Based on the sensory style quality characteristics and chemical composition differences, the long-cycle tobacco leaves in stock from the same production area are integrated and blended to form formula modules with different functional effects, and small-grade tobacco leaves are blended into the formula modules in a certain proportion to form functional modules that can play a specific role in the leaf group formula.

[0009] 4) Targeted application of flavor regulators to the above functional modules to further improve the formula applicability of the functional modules.

[0010] 5) In the step 1), the tobacco information sorted and counted includes information such as variety, origin, part, grade, etc. Tobacco with an inventory cycle of more than two years is defined as long-cycle inventory tobacco, and medium-grade and above tobacco with small inventory and weak formula applicability is defined as low-grade tobacco.

[0011] 6) In step 2), the sensory style quality evaluation method is carried out in accordance with YC / T 530-2015 sensory evaluation method for quality style characteristics of flue-cured tobacco leaves, and the focus should be on the raw material flavor (light flavor, medium flavor, strong flavor) and the aroma indexes of roasted sweet aroma, burnt sweet aroma, light sweet aroma, green aroma, woody aroma, burnt aroma, etc.; the quality indexes focus on the aroma quality, smoke concentration, impurities, strength, irritation, and permeability. Chemical component detection includes conventional components such as total sugar, total nitrogen, nicotine, and protein.

[0012] 7) In step 3), the formation of functional modules includes two assembly links: one is to mix the long-cycle tobacco leaves in the same production area in proportion to form a formula module, and the other is to integrate and mix small-grade tobacco leaves into the formula module to form a functional module. The principle of mixing small-grade tobacco leaves should be to improve the aroma texture and richness of aroma. The functional modules should not exceed 3. Module 1 has good aroma quality and moderate smoke concentration, which improves the richness and layering of aroma in the leaf group formula; Module 2 has a certain concentration and moderate strength, which improves the smoke and taste comfort in the leaf group formula; Module 3 is mainly used to improve the filling performance of the leaf group without causing obvious impurities and irritation.

[0013] 8) In step 4), the tobacco raw materials are mixed based on the principle of combining sensory characteristics and chemical composition. The number of long-term tobacco varieties in the module should be 3-7, the proportion of each single tobacco should not exceed 40%, and the proportion of small-grade tobacco should not exceed 17%. The sugar-alkali ratio of module 1 should be >10.5, and the Schmuck value should be between 2.7-3.3; the sugar-alkali ratio of module 2 should be between 9-10.5, and the Schmuck value should be between 2.3-2.7; the sugar-alkali ratio of module 3 should be between 8-9, and the Schmuck value should be below 2.3.

[0014] The beneficial effects of the present invention are as follows: it takes into account the combination and blending of long-cycle tobacco leaves in inventory and small-grade tobacco leaves with slightly better quality, gives play to the coupling effect of tobacco leaf raw materials with different quality characteristics in storage, and combines the material fragrance application technology to comprehensively improve the quality of tobacco leaves in inventory, providing a way to improve the resource utilization efficiency and use value of tobacco leaf raw materials.

[0015] The present invention alleviates inventory pressure while taking into account the combination of long-cycle tobacco leaves in inventory and small-grade tobacco leaves with better quality, develops functional modules based on long-cycle and small-grade tobacco leaves, and realizes the coupling effect of the two. It is a way to synergistically improve the formula applicability of inventory raw materials and the value of effective resource utilization.

[0016] The present invention proposes a method for improving the quality of long-cycle and small-grade tobacco leaves in stock. Based on the sensory quality and chemical composition of the long-cycle tobacco leaves and small-grade tobacco leaves in stock, a formula module including both long-cycle tobacco leaves and small-grade tobacco leaves is designed, and the module availability is improved by applying a flavor regulator.
