Problems solved by technology

However, sun-cured red tobacco leaves have shortcomings such as rough smoke, excessive irritation, and heavy local miscellaneous gases. Therefore, through extraction and separation, the key components of sun-cured red tobacco are extracted and enriched, and prepared into tobacco extracts and added to low-tar cigarettes. , to provide new ideas for flavoring low-tar cigarettes

preparation example Construction

[0020] The invention relates to a preparation method of red sun-cured tobacco extract.

[0021] Sun-cured red tobacco has strong aroma, high strength, relatively high nicotine content, low sugar and tar content, and has unique flavor and aroma characteristics. It can be used to increase flavor and improve flavor in the formulation of cigarette leaves. However, sun-dried red tobacco leaves have shortcomings such as rough smoke, excessive irritation, and heavy local miscellaneous gases. Therefore, it is necessary to extract and separate important aroma substances in order to make the aroma-enhancing effect more obvious.

[0022] A. Sun-dried red tobacco leaves are first dried at 50°C for 60 minutes, then crushed with a high-speed pulverizer, and then sieved with a 20-40 mesh sieve, and the sifted smoke powder is placed in a sealed bag for later use.

[0023] In this step, the tobacco leaves are dried to make them brittle, which is beneficial to crushing. Tobacco leaves undergo ...

Embodiment 1

[0037] Example 1: Preparation of Sun-cured Red Tobacco Extract——Determination of Ethanol Concentration

[0038] The steps of this embodiment are as follows:

[0039] A. Sun-dried red tobacco leaves are first dried at 50°C for 60 minutes, then crushed with a high-speed pulverizer, and then sieved with a 20-40 mesh sieve, and the sifted smoke powder is placed in a sealed bag for later use.

[0040] B. Extract the tobacco powder treated in step A) and ethanol solutions with concentrations of 45, 55, 65, 75, and 85% at 60°C for 2 hours according to the mass ratio of 1:10, and calculate the yield of tobacco extract and It was subjected to sensory evaluation.

[0041] The results showed that the ethanol extracts with 45% and 55% concentration had strong stimulation, heavy miscellaneous gas, no obvious aroma enhancement effect, and medium yield; 65 and 75% concentration ethanol extract had moderate stimulation, had miscellaneous gas, and had an increased effect on cigarettes. Fragr...

[0042] Example 2: Preparation of Sun-cured Red Tobacco Extract——Determination of Extraction Temperature

[0043] The steps of this embodiment are as follows:

[0044] A. Sun-dried red tobacco leaves are first dried at 50°C for 60 minutes, then crushed with a high-speed pulverizer, and then sieved with a 20-40 mesh sieve, and the sifted smoke powder is placed in a sealed bag for later use.

[0045] B. Extract the smoke powder treated in step A) with the ethanol solution with a concentration of 65%, according to the mass ratio of 1:10, extract at 45, 55, 65, 75, and 85°C for 2 hours, and calculate the yield of tobacco extract and It was subjected to sensory evaluation.

[0046] The results showed that: the extracts prepared at 45-55°C had a strong sense of irritation, heavy miscellaneous gas, no obvious aroma-enhancing effect, and a low yield; the extracts prepared at 55 and 65°C had low irritation, miscellaneous gas, and aftertaste There is a slight residue, the effect of fla...

Abstract

The invention relates to a preparation method for a tobacco extract of dark sun-cured tobacco. The method comprises the following steps: dark sun-cured tobacco leaves are dried, ground and sieved; tobacco powder is mixed with an alcoholic solution with the mass fraction of 65%-75% in a mass ratio of the tobacco powder to the alcoholic solution being 1:8-14, the mixture is subjected to extraction at the temperature of 55-65 DEG C for 1-2 h, solid-liquid separation is performed after extraction, and a product is concentrated; a primary extract is subjected to molecular distillation, second-level molecular distillation light components and fourth-level molecular distillation light components are assembled in the ratio being 1:0.8-2.4, and the final tobacco extract of the dark sun-cured tobacco is obtained. The prepared tobacco extract of the dark sun-cured tobacco can improve aroma of a low-tar blank cigarette, improve the smoke concentration, improve the aftertaste and reduce stimulation, an aroma enhancing purpose is achieved, and novel thought is provided for aroma enhancement of low-tar cigarettes.

Description

technical field [0001] The invention belongs to the technical field of spices. More specifically, the present invention relates to a red sun-cured tobacco extract, and also relates to a preparation method of the extract. technical background [0002] In recent years, people have paid more and more attention to the problems of smoking and health. Chinese-style cigarettes have vigorously developed low-tar technology, and the proportion of expanded stems, expanded tobacco, and sheets in leaf formulations has increased. The application of cigarette ventilation dilution technology and retention technology is more common. While reducing harm and reducing coke, cigarette satisfaction and smoke concentration are greatly reduced, and maintaining the taste of cigarettes has become a major challenge for the tobacco industry. Therefore, flavoring and adding materials in tobacco are becoming more and more important. The extract prepared by extracting and separating from tobacco is the ...
