Example Embodiment

[0070] Example 1

[0071] The sample is sliced ​​tobacco shredded after redrying tobacco leaves in Jilin producing area. Place the shredded tobacco in a blast drying box and treat it at 50°C and a drying temperature for 4 hours. Then accurately weigh 0.5g 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 immersion for 5 minutes; then place the solution in an ultrasonic breaker, and put a 6mm diameter The ultrasonic horn is inserted into the extraction solvent, the ultrasonic power is set to 665W, the continuous ultrasonic time is 3s, the intermittent time is 9s, the cycle is performed and the total ultrasonic duration is 20min, and the tobacco is crushed by ultrasonic. After sonication, the container was sealed, and the immersion extraction was continued for 5 minutes. Transfer the mixed slurry into a 2mL centrifuge tube through a straw, set the centrifugal speed to...

[0072] Example 2

[0073] The solution to be tested containing tobacco flavor components extracted by ultrasonic crushing in the foregoing Example 1 was determined by gas chromatography and mass spectrometry. At the same time, the same sample as in Example 1 above was added to the internal standard, and the organic solvent extraction method was used for extraction. The extraction time was 24 hours. The obtained extract was also determined by gas chromatography and mass spectrometry. The two extraction methods are gas chromatography. The determination conditions of mass spectrometry are the same, using NIST05 database (matching degree ≥90) for qualitative analysis, and internal standard method for semi-quantitative analysis. See the specific test results 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 of the ...

[0077] Example 3

[0078] The sample is a tobacco leaf after redrying tobacco leaves in Anhui producing area. The tobacco leaves are placed in a constant temperature and humidity box, and equilibrated for 48 hours at 25°C and 60% humidity. Cut them into pieces with scissors, control the size within 1.5cm×1.5cm, then accurately weigh 1g of smoked slices, put them into a 50mL round-bottomed plastic tube with a screw cap, add 30mL methanol, and place in an ice water bath for freezing and immersion for 5 minutes; Place the solution in the ultrasonic disruptor, insert the 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, the cycle is performed and the total ultrasonic duration is 15min, using ultrasonic Crush the smoke pieces. After sonication, the container was sealed, and the immersion extraction was continued for 5 minutes. Transfer the mixed slurry into a 2mL centrifuge ...

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...
