Problems solved by technology

[0003] Although the traditional tobacco petroleum ether extract can better make up for the smoke aroma, but because there is no selective separation of the components, it contains some substances that have a negative impact on the smoking taste of cigarettes. Side effects such as discomfort, roughness, and dryness

Embodiment 1

[0029] Take 100 g of Zimbabwean tobacco leaves and 800 g of petroleum ether, extract for 2 h at 40° C. under 50 kHz ultrasonic treatment, and the ultrasonic power is 120 W, and separate the filtrate and filter residue.

[0030] The filtrate was concentrated until 34.5 g of a concentrate was obtained.

[0031] In terms of weight ratio, weigh 50:1, 20:1, 10:1, 5:1, 3:1, 2:1, 1:1, 1:5 petroleum ether and ethyl acetate mixture as eluent , 500mL for each gradient. The concentrate was loaded onto a silica gel column for gradient elution, and the receiving solutions were numbered and marked according to the order in which they flowed out. A total of 155 tubes of receiving solutions were obtained, each about 26ml. Take 75-130 tubes of receiving liquid, concentrate at 45°C and 0.08MPa pressure to remove the solvent, and obtain the aromatizer.

[0032] The prepared flavoring substance is diluted with ethanol with a mass concentration of 95%, and sprayed evenly into shredded tobacco in...

Embodiment 2

[0036] Take 100 g of Zimbabwean tobacco leaves and 800 g of petroleum ether, reflux extraction at 40° C. for 2 h under 50 kHz ultrasonic treatment, the ultrasonic power is 120 W, and separate the filtrate and filter residue.

[0037] The filtrate was concentrated until 36.5 g of a concentrate was obtained.

[0038] In terms of weight ratio, weigh 10:1, 5:1, 1:1, 1:5, 1:10, 1:20, 1:30, 1:50 petroleum ether and ethyl acetate mixture as eluent , 500mL for each gradient. The concentrate was loaded onto a silica gel column, and the gradient elution was carried out. The receiving solution was numbered and marked according to the order of outflow, and a total of 265 tubes of receiving solution were obtained, each tube was 15ml, and they were numbered sequentially. Take the combined liquid from tubes 165-228 and concentrate at 45°C under a pressure of 0.08MPa to remove the solvent to obtain the aromatizer.

Abstract

The invention relates to a preparation method of an aroma substance in a Zimbabwe tobacco extractive. The preparation method comprises the following steps: carrying out supersonic extraction on taken Zimbabwe tobaccos by using petroleum ether as a solvent, concentrating, then carrying out chromatographic separation by using a silica column, using a mixture of the petroleum ether and ethyl acetate in different concentration proportions as an eluant, collecting specific part of eluant, mixing and then concentrating to obtain the aroma substance. The aroma substance obtained by the method has the advantages of being capable of increasing the self aroma of tobaccos, increasing the smoke concentration of cigarettes, improving the quality of aroma, covering up offensive odor, enabling the smoke to be fine and soft and improving the sweet feel.

Description

【Technical field】 [0001] The invention relates to a method for preparing aromatized substances in Zimbabwean tobacco leaf extract, a product obtained by the method, and an application of the obtained product in cigarettes. 【Background technique】 [0002] As people pay more and more attention to "smoking and health", tar reduction and harm reduction have gradually become the mainstream trend of the global tobacco industry, and the proportion of low-tar cigarettes in the entire cigarette market has increased. However, the flavoring substances in the tobacco are also lost while the tar is reduced, so the flavor compensation technology is particularly important in the cigarette flavoring technology. Therefore, it is an effective way to use tobacco raw materials to extract aroma substances to compensate the aroma of low-tar cigarettes. [0003] Although the traditional tobacco petroleum ether extract can better make up for the smoke aroma, but because there is no selective separ...
