Problems solved by technology

[0009] It can be seen from the above literature that many tobacco workers are trying to solve the problem of poor quality and low utilization rate of unsuitable upper tobacco leaf raw materials through follow-up chemical and physical treatment methods. Although these methods have certain effects, there are also certain problems. Defects, such as Qin Guangyong and others who use dry cleaning to wash tobacco leaves only clean the substances on the surface of the tobacco leaves, it is difficult to effectively wash out the substances inside the tobacco leaves that have a negative impact on the sensory quality, and the dry cleaning agent may cause residues; the other three methods mentioned above use Adding substances or high-temperature treatment to cover up or modify the quality defects of unsuitable tobacco leaves has limited effect or limited realization ability (equipment, substance use license)

Embodiment 1

[0031] 1. Processing method

[0032] Weigh 2kg of shredded tobacco B3K (upper variegated color grade 3) produced in Zhangjiajie, Hunan Province in 2012 after storage and alcoholization, put it into a 25-liter airtight glass container, add 10kg of ethanol solution with a volume concentration of 70%, and let it stand at a temperature of 50°C After processing for 30 minutes, under the vacuum condition of -0.050~-0.055Mpa (at this time, there are bubbles coming out of the processing solvent), the solid-liquid separation is carried out after 15 minutes of reduced pressure treatment, and the shredded tobacco is taken out and dried at 50°C until the water content is 12.5 wt%. Sampling for detection analysis and sensory evaluation.

[0033] 2. Test results:

[0034] (1), main chemical components of shredded tobacco

[0035] Table 1 below shows the results of detecting the main chemical components in shredded tobacco before and after treatment by using a fluid analyzer according to ...

Embodiment 2

[0043] 1. Processing method

[0044] Weigh 2.2kg of B2K (upper variegated second-grade grade 2) cigarette produced in Hunan Xiangxi Autonomous Prefecture in 2012 after storage and alcoholization, put it into a 25-liter airtight glass container, add 11kg of ethanol solution with a volume concentration of 35%, and store it at a temperature of 65°C. After standing still for 30 minutes, under the vacuum condition of -0.035~-0.045Mpa (at this time, there are bubbles in the processing solvent), the solid-liquid separation is carried out after 10 minutes of decompression treatment, and the solid-liquid separation is carried out. Preliminary drying under conditions to a water content of 22wt% was taken out and cut into shreds, and then dried to a water content of 12wt% before sampling for detection, analysis and sensory evaluation.

Embodiment 3

[0055] 1. Processing method

[0056] Weigh 40g cut tobacco produced in Yongshun, Xiangxi, Hunan in 2011, after storage and alcoholization, put it into a 1-liter airtight glass container, and process it one by one according to the conditions described in Table 5; then separate solid-liquid, cut tobacco After taking it out, dry it at 50°C until the water content is 12.5wt%, take it out, and take a sample for sensory evaluation.

Abstract

The invention discloses a method for improving inapplicable upper tobacco leaf raw material quality. According to the method, inapplicable upper tobacco leaf raw materials are placed in an ethanol solution to be soaked, then vacuum decompression processing is conducted, and next solid-liquid separation is conducted; after the inapplicable upper tobacco raw materials obtained after the solid-liquid separation is conducted are dried, the product formula processing process can be conducted. The method is easy to operate and low in cost, the inapplicable upper tobacco raw materials processed through the method still have better forming and processing performance, the inherent sensory quality is obviously improved, the utility value of the inapplicable upper tobacco leaves in cigarettes is increased, and the inventory pressure of the inapplicable upper tobacco leaves is effectively relieved for cigarette companies.

Description

technical field [0001] The invention relates to a method for improving the quality of unsuitable upper tobacco leaf raw materials, which belongs to the field of tobacco. Background technique [0002] The unsuitable upper tobacco leaf raw materials mentioned in this method refer to the upper tobacco leaves that are currently unsuitable for use in the brand formula of cigarette industry enterprises, including low-grade regular tobacco leaves (such as B3F, B4F, B4L, B3R, etc.), variegated tobacco leaves ( Such as B1K, B2K, B3K), microstrip green tobacco leaves (such as B2V, B3V), etc. The quality defects of these tobacco leaves are more obvious, and the usability is not high. For example, the upper part of the variegated tobacco leaves is caused by tight tissue structure, uncoordinated internal chemical components (high alkaloid content, low reducing sugar and sugar-alkaline ratio), rough smoke, obvious dry coke gas and nitrogen gas, and concentrated and large strength.
