preparation example Construction

[0020] The present invention relates to a preparation method of red tobacco tobacco extract.

[0021] Sun-red tobacco smoke has a strong aroma, high energy, relatively high nicotine content, low sugar and tar content, and has unique smoking and aroma characteristics. However, the sun-red tobacco leaves have the disadvantages of rough smoke, excessive irritation, and heavy local miscellaneous gas. Therefore, it is necessary to extract and separate the important aroma substances to make the aroma enhancement effect more obvious.

[0022] A. The sun-red tobacco leaves are first baked at 50°C for 60 minutes, then pulverized with a high-speed pulverizer, then sieved with a 20-40 mesh sieve, and the sifted tobacco 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 favorable for pulverization. Tobacco leaves undergo high-speed physical crushing, their internal tissue structure is destroyed, and the powde...

Embodiment 1

[0037] Example 1: Preparation of Sunburn tobacco extract—Determination of ethanol concentration

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

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

[0040] B, the cigarette powder and the ethanol solution with the concentration of 45, 55, 65, 75, 85% processed in step A), according to the mass ratio of 1:10, were extracted at 60 ° C for 2h, and the yield of the tobacco extract was calculated and Sensory evaluation was performed on it.

[0041] The results showed that: 45% and 55% ethanol extracts had strong irritation, heavier odor, and the aroma enhancement effect was not obvious, and the yield was moderate; Fragrance effect, high yield; 85% concentration of ethanol extract moderate irritation, strong sense of miscellaneous gas, unclean after...

[0042] Example 2: Preparation of Sunburn tobacco extract - Determination of extraction temperature

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

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

[0045] B, the cigarette powder and the ethanol solution with the concentration of 65% treated in step A) are 1:10 according to the mass ratio, and are extracted for 2h at 45, 55, 65, 75, 85 ℃, and the yield of the tobacco extract is calculated and Sensory evaluation was performed on it.

[0046] The results showed that the extracts prepared at 45~55℃ had strong irritating feeling, heavier odor, and the aroma enhancement effect was not obvious, and the yield was low. Slight residue, obvious aroma-enhancing effect, and medium yield; the extract prepared at 75 and 85 ℃ has strong irritation, gener...

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 fragrances. More specifically, the present invention relates to a red tobacco tobacco extract, and also relates to a preparation method of the extract. technical background [0002] In recent years, people's attention has been paid to the issue of smoking and health. Chinese cigarettes have vigorously developed low-tar technology. The proportion of expanded cut stems, expanded cut tobacco and thin slices in the leaf group formula has increased, and the application of cigarette ventilation dilution technology and interception technology is more common. While reducing harm and reducing coke, the satisfaction of cigarettes and the concentration of smoke are greatly reduced, and maintaining the aroma and taste of cigarettes has become a major challenge for the tobacco industry. As a result, flavorings in tobacco are becoming increasingly important. The extract prepared by extraction and separation using tob...
