Problems solved by technology

[0005] The purpose of the present invention is to provide a method for extracting tobacco aroma components and its application, and provide a method for assisting extraction of tobacco aroma components by ultrasonic crushing, which is used to solve the problem of extracting tobacco aroma components in the prior art and to dry and grind the samples in advance. Crushing treatment requires a large amount of samples, the sample preparation process consumes a large amount of tobacco leaf raw materials, and the aroma components are seriously lost during the drying and grinding process; or requires long-term impregnation treatment, which will cause chemical reactions to affect the structure and properties of aroma components in tobacco.

Embodiment 1

[0071] The sample is sliced ​​tobacco shredded after re-roasting tobacco leaves in Jilin production area. The shredded tobacco was placed in a blast drying oven, and treated at 50° C. for 4 hours under drying temperature conditions. Then accurately weigh 0.5g of shredded tobacco, put it into a 50mL round-bottomed plastic tube with a screw cap, add 10mL of absolute ethanol, and place it in an ice-water bath for freezing and impregnating for 5 minutes; The ultrasonic horn was inserted into the extraction solvent, the ultrasonic power was set to 665W, the continuous ultrasonic time was 3s, the intermittent time was 9s, the cycle was carried out and the total ultrasonic time was 20min, and the shredded tobacco was crushed by ultrasonic waves. After the ultrasonic crushing is completed, seal the container and continue to immerse and extract for 5 minutes. Transfer the mixed slurry into a 2mL centrifuge tube through a pipette, set the centrifugation speed to 5000rpm, and centrifuge...

Embodiment 2

[0073] The solution to be tested containing tobacco aroma components extracted by ultrasonic crushing in the above-mentioned Example 1 was determined by gas chromatography-mass spectrometry. Simultaneously, with the same sample in above-mentioned embodiment 1, add internal standard, adopt organic solvent extraction method to extract, extraction time is 24h, the extraction liquid that will obtain also adopts gas chromatography-mass spectrometry to measure, the gas chromatography of two kinds of extraction methods The determination conditions of mass spectrometry were the same, the NIST05 database (matching degree ≥ 90) was used for qualitative analysis, and the internal standard method was used for semi-quantitative analysis. For specific test results, see Figure 1-2 ,Table 1.

[0074] It can be seen from Table 1 that the chromatographic peak area of ​​the aroma components of the extract obtained by ultrasonic crushing extraction technology is significantly larger than that o...

Embodiment 3

[0078] The sample is the sliced ​​tobacco leaves after re-roasting the tobacco leaves in Anhui production area. The tobacco leaves were placed in a constant temperature and humidity box, and balanced for 48 hours at 25° C. and 60% humidity. Cut it into pieces with scissors, and control the size within 1.5cm×1.5cm, then accurately weigh 1g of the cigarette slices, put it into a 50mL round-bottomed plastic tube with a screw cap, add 30mL of methanol, and place it in an ice-water bath for 5 minutes of freezing and impregnation; Put the solution in the ultrasonic breaker, insert a 6mm diameter ultrasonic horn into the extraction solvent, set the ultrasonic power to 665W, the continuous ultrasonic time to 3s, the intermittent time to 9s, and the cycle is carried out and the total ultrasonic time is 15min. Crush the flakes. After the ultrasonic crushing is completed, seal the container and continue to immerse and extract for 5 minutes. Transfer the mixed slurry into a 2mL centrifu...

Abstract

The invention provides an extraction method for flavor components in tobacco. The extraction method comprises the following steps of carrying out equalization treatment or drying treatment on tobacco shred or tobacco leaves, and enabling the water content of a sample to be uniform; cooling after putting the tobacco shred or tobacco leaves in an extraction solvent for dipping; putting mixed liquor in an ultrasonic crusher, and crushing the tobacco shred or tobacco leaves by utilizing ultrasonic waves; sealing a container after crushing the tobacco shred or tobacco leaves, centrifugally removing a solid-phase matter after continuously dipping the tobacco shred or tobacco leaves, thus obtaining an extraction solution of the flavor components in the tobacco. The invention further provides the application of the extraction method for the flavor components in the tobacco in tobacco flavor component content analysis and tobacco extractive preparation. According to the extraction method of the flavor component in the tobacco, disclosed by the invention, in-advance crushing treatment does not need to be carried out on the tobacco shred or tobacco leaves through adopting an ultrasonic crushing and extracting technology, the loss of the flavor component is effectively reduced, the extraction efficiency is high, the extraction technology is simplified, the flavor component in the tobacco can be quantified, and the tobacco extractive can be effectively prepared.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and relates to a method for extracting tobacco aroma components and its application, in particular to a method for extracting tobacco aroma components by ultrasonic crushing and its application in the quantitative analysis of tobacco aroma components and the preparation of tobacco extracts. Background technique [0002] Maximizing the raw material characteristics and advantages of Chinese tobacco leaves is the key to improving the core competitiveness of Chinese-style cigarettes. With the continuous deepening of research on tobacco processing technology, the evaluation of tobacco quality has gradually shifted from focusing on physical indicators to focusing on the internal quality of tobacco. How to effectively extract the aroma components in tobacco and conduct accurate quantitative analysis of specific components is the key to optimization. Tobacco processing technology and prerequisites for im...
