Problems solved by technology

[0004] The prior art has the following deficiencies: first, the method of using biological enzymes and microorganisms to treat low-grade tobacco leaves requires accurate control of the activity, application amount, and action time of the enzymes and microorganisms on the one hand, and on the other hand requires the treatment. Tobacco leaves are subjected to high-temperature inactivation treatment, but in actual production, there is no large-scale processing equipment suitable for tobacco leaf enzymes and microbial treatment, and the method of high-temperature biological inactivation in the actual tobacco leaf large-scale silk processing process, due to the material It is more difficult to control and measure accurately, and when a small amount of uninactivated enzymes or microorganisms remain in the treated tobacco leaves, it will cause serious quality risks to the cigarette products using the tobacco leaves; second, Using the existing cigarette shredded technology and process adjustment method, although the quality of low-grade tobacco leaves can be partially improved, but because the temperature and moisture of the tobacco leaves are only adjusted within a certain range, the macromolecules such as starch and protein with a high content in the tobacco leaves will not be affected. Substances such as cellulose and hemicellulose that are insoluble in water have little influence, so the quality of tobacco leaves is only partially improved; third, the processing method of extracting some components from low-grade tobacco leaves has a higher cost, compared with tobacco leaf production. Investing in manpower, material resources and other costs is only a remedial measure for discarded low-grade tobacco leaves
However, since γ-ray irradiation only degrades macromolecules, the degraded sugar and nitrogen substances still exist in the tobacco leaves, and the incongruous chemical components such as sugar-to-nitrogen ratio and nitrogen-alkaline ratio of tobacco leaves still exist, and the sensory quality is only limited. is slightly improved

Embodiment 1

[0025] Gansu Qingyang 2015 low-grade tobacco leaves stocked by a domestic cigarette industry enterprise, the lower part, grade X4F ， According to the sensory evaluation, its aroma quality is poor, the amount of aroma is small, the miscellaneous gases such as dry coke gas and woody gas are obvious, the mouth is dry and irritating, and the aftertaste is poor. The proportion of use in the five types of cigarette formulas is 3%. In order to improve its organoleptic quality and increase its formula usage ratio, the low-grade tobacco leaves are treated by the method of the present invention. The specific process is as follows:

[0026] 1. γ-ray irradiation: Gansu Qingyang X4F low-grade tobacco leaves in 2015 were irradiated with a γ-ray irradiation device, and the irradiation dose was set at 75 kGy.

[0027] 2. Washing: Wash the irradiated low-grade tobacco leaves with water tank type moisture regain equipment, the water temperature is 50°C, and the washing time is 15s.

[0028] 3...

Embodiment 2

[0036] Henan Luoyang 2013 low-grade tobacco leaves stocked by a domestic cigarette industry enterprise, lower part, grade X4F ， The results of sensory evaluation showed that the miscellaneous odors such as green odor, dry coke odor, woody odor, and earthy odor were obvious, and there were residues in the mouth, with a slightly bitter aftertaste. Two methods are adopted respectively to process the low-grade tobacco leaves, one is to only use gamma-ray irradiation treatment; the other is to adopt the combined treatment of gamma-ray irradiation, water washing and high-temperature drying of the present invention, and the specific process is as follows:

[0037] Method 1: The 2013 low-grade tobacco leaves in Luoyang, Henan were irradiated with a γ-ray irradiation device, and the irradiation dose was set at 85 kGy.

[0038] Method Two:

[0039]1. Gamma ray irradiation: Henan Luoyang 2013 low-grade tobacco leaves were irradiated with a γ ray irradiation device, and the irradiation d...

Embodiment 3

[0046] Liaoning Kuandian 2014 low-grade tobacco leaves stocked by a domestic cigarette industry enterprise, the part is the upper part, grade B4F, after sensory evaluation, it has less aroma, obvious miscellaneous gases such as green, dry and green, dry, The irritation is obvious, and there are residues in the mouth. The tobacco leaves are treated by adopting the method of the invention. The specific process is as follows:

[0047] 1. Gamma ray irradiation: After the 2014 Liaoning Kuandian B4F low-grade tobacco leaves were loosened, rehydrated and shredded in the cigarette shred production line, the shredded tobacco was irradiated with a gamma ray irradiation device, and the irradiation dose was set at 130kGy.

[0048] 2. Increase the moisture content of shredded tobacco: the irradiated shredded tobacco is rehydrated with a super moisture conditioner, and the moisture content of the shredded tobacco for export is set at 25%.

[0049] 3. High-temperature drying: transport the...

Abstract

A method for improving the sensory quality of low-grade tobacco leaves is characterized in that it includes the following specific steps: firstly irradiating low-grade tobacco leaves with gamma rays; secondly, applying water evenly to the irradiated tobacco leaves to increase the moisture content to 22% ‑28%, or soak the irradiated tobacco leaves in water at 45‑65°C for 5‑30s; finally, dry the tobacco leaves with higher moisture content or wash them at high temperature to adjust their moisture content to 12%‑13 %. Compared with the existing method for improving the quality of low-grade tobacco leaves, the present invention can not only degrade the macromolecular substances in low-grade tobacco leaves that affect the sensory quality, but also remove the content of small molecular substances that affect the coordination of chemical components of tobacco leaves, and significantly improve the quality of low-grade tobacco leaves. Sensory quality, enhance its use value.

Description

technical field [0001] The invention relates to the field of cigarette tobacco raw materials, in particular to a method for improving the sensory quality of low-grade tobacco leaves. Background technique [0002] Low-grade tobacco leaves generally refer to low-grade tobacco leaves with obvious sensory quality defects in tobacco leaf raw materials, which have less aroma, heavy miscellaneous gas, strong irritation, poor aftertaste, and obvious dryness. From the perspective of chemical composition, its total nitrogen or total sugar, etc. High content, high macromolecular substances such as starch or protein, low content of reducing sugar, aroma components, etc., and overall uncoordinated chemical composition. Therefore, in the process of using tobacco raw materials, low-grade tobacco leaves are often not harvested or purchased. Abandoned in the field, or only used in low-grade cigarette formula, forming a waste of resources. [0003] In order to improve the use value of low-gr...
