preparation example Construction

[0039] The preparation method of tobacco leaf extract described in the embodiment of the present application comprises the following steps:

[0040] a) crushing the tobacco leaves to below 300 mesh;

[0041] b) extracting with an aqueous ethanol solution to obtain an extract;

[0042] c) filtering the extract to obtain the filtrate;

[0043] d) adding glycerin to the filtrate as a stabilizer to obtain the final tobacco extract.

[0044] In the above step a), the tobacco leaves are tobacco leaves produced in Zimbabwe. More preferably, the tobacco leaves include Zimbabwe tobacco leaves L3L and Zimbabwe tobacco leaves L3O.

[0045] The Zimbabwean tobacco extract L3L refers to the use of Zimbabwean tobacco, which is the third quality grade of the upper tobacco leaf in the middle maturity grade, which is the third quality grade of the standard grade, and has a lemon color.

[0046] The Zimbabwean tobacco extract L3O refers to Zimbabwean tobacco, which is selected from the middl...

Embodiment 1

[0052] Weigh 100g of tobacco extract obtained from Zimbabwean tobacco L3L, 50g of ethanol, and 50g of water and stir evenly. Set the temperature of the tower kettle to 195°C and start heating. After about 15 minutes, the temperature at the top of the tower reached 72°C, and reflux began to appear. Keep the total reflux for 20 minutes, the whole tower reaches a steady state, the temperature of the tower still does not change, it is about 89°C, and the material starts to discharge. When the temperature of the tower bottom reached 94°C, the discharge was stopped to obtain Fraction 1. Continue to raise the temperature of the tower kettle to 200°C, maintain total reflux for 15 minutes, start discharging, and stop discharging when the temperature of the tower kettle reaches 98°C to obtain Fraction 2. Then the above operation was continued to obtain Fraction 3.

[0053] After a small trial evaluation, Fraction 1 has an aroma-inducing effect, but the effect is not very significant, ...

Embodiment 2

[0055] The rectification fraction 2 in Example 1 was diluted with glycerol triacetate to a 1wt% solution, and added to the cellulose acetate of the filter tip of reduced-scorch cigarettes from a tobacco factory, and the mass ratio of the added amount to the cellulose acetate was 10wt%. As 2# sample.

Abstract

The invention provides an incense for filter tip and its preparation method and application. The preparation method of the incense for filter tip comprises the following steps: 1) mixing ethanol, water and tobacco extract to form a mixed liquid; 2) conducting the mixed liquid Extraction by rectification, extracting fractions with a temperature below 100°C to obtain incense for filter tips. In the technical solution of the present application, tobacco extracts are refined to extract effective aroma components, which are dissolved in glycerol triacetate and sprayed onto the cellulose acetate of the filter to compensate for the loss of filter aroma and provide a significant Flavoring effect, making cigarette smoke mellow.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a filter incense and its preparation method and application. Background technique [0002] With the continuous improvement of the level of civilization in today's society, people gradually pay attention to the importance of health. Cigarettes, as a kind of hobby, must keep up with the trend of the times and reduce their harm, so most tobaccos start to work on reducing coke. However, it is easy to lose the aroma components in the tobacco while reducing the coke. At present, most of the tar reduction work adopts the filtering effect of the harmful components in the smoke through the cigarette filter to reduce the harm. [0003] Most of the filters currently used are acetate filters. Peng Chuanxin found that the weight of the filter rod can be increased and the suction resistance can be increased to achieve coke reduction; Yu Chuanfang believes that increasing the length of the filter rod ...
