Embodiment 1

[0028] Example 1 Preparation of cigarette tar extract

[0029] A method for preparing a cigarette butt tar extract with aroma-inducing properties comprises the following steps:

[0030] (1) Pretreatment of cigarette butts: tear off the outer wrapping paper of cigarette butts, and cut the tow into small sections less than 1 cm in length;

[0031] (2) Add 100 g of the pretreated cigarette butts into 1 L of absolute ethanol, extract in a reflux water bath at 60° C. for 4 h, and centrifuge at 1000 r / min for 2 min to obtain an extract;

[0032] (3) Distill the extract under reduced pressure with a water pump to remove the organic solvent, then connect it to an oil pump vacuum system, adjust the pressure to 0.5mmH, heat slowly, and collect fractions below 200°C;

[0033] (4) The collected fractions were extracted 3 times with chloroform, the extracts were combined, then concentrated and desolvated on a rotary evaporator, the temperature was controlled at 45 ° C, the pressure was 2...

Embodiment 2

[0052] Example 2 Aroma-inducing properties of cigarette tar extract

[0053] The heat-not-burn cigarette sample A (HnB sample A) was prepared by adding the tar extract prepared in Example 1 to the condensation auxiliary material of the heat-not-burn cigarette at an addition ratio of 3% by weight of the heat-not-burn cigarette.

[0054] The tar extract prepared in Example 1 was added to the filter auxiliary material of the heat-not-burn cigarette at an addition rate of 2% by weight of the heat-not-burn cigarette to prepare the heat-not-burn cigarette sample B (HnB sample B).

[0055]Heat-not-burn cigarette sample C (HnB sample C) was prepared by adding the tar extract prepared in Example 1 to reconstituted shredded tobacco of heat-not-burn cigarettes at an addition ratio of 4% by weight of heat-not-burn cigarettes.

[0056] After the cigarette samples made by the above scheme and the cigarettes without tar extract were balanced for 24 hours in a constant temperature and humid...

Embodiment 3

[0060] Example 3 Selection of preparation method conditions

[0061] 1. Selection of organic solvents

[0062] Use methanol, dichloromethane, absolute ethanol, glycerin, petroleum ether, polyethylene glycol 400 to extract the pretreated cigarette butts, the ratio of solid to liquid is 1:10 (g / mL), the extraction time is 2 hours, and the water bath The temperature was 60°C, and the extraction was performed once. The influence of different solvents on the extraction effect (the content of the extracted components per g of cigarette butt) was compared and analyzed. The test results are shown in Table 2. It can be seen from Table 2 that the extraction effect is the best when using absolute ethanol.

Abstract

The invention provides a method for preparing a cigarette butt tar extract with an aroma characteristic and application of the cigarette butt tar extract in cigarettes, and the method comprises the following steps: (1) adding cigarette butts into an organic solvent for extraction, and centrifuging after extraction to obtain an extracting solution; and (2) distilling the extracting solution under reduced pressure to remove the organic solvent, distilling under vacuum pressure, and collecting fractions below 200 DEG C to obtain the tar extract. Waste cigarette butts are used as raw materials, and organic solvent extraction and reduced pressure distillation separation are used, so that harmful substances in waste cigarette butt tar are removed, and aroma characteristic components of the wastecigarette butt tar are reserved; by applying the cigarette butt tar extract to heat-not-burn cigarettes, aroma, smoke and taste characteristics of the heat-not-burn cigarettes are improved, and the problem that the heat-not-burn cigarette is dull in cigarette smell or poor in aroma puff-by-puff release stability is effectively solved.

Description

technical field [0001] The invention relates to a method for preparing a tar extract with aroma-inducing properties from waste cigarette butts and its application in cigarettes, belonging to the technical field of tobacco technology. Background technique [0002] Cigarettes refer to tobacco products in which shredded tobacco is rolled into strips with cigarette paper. Cigarettes are mainly composed of four parts: shredded tobacco, cigarette paper, tipping paper and filter. Cigarette paper (also known as coil paper) is a special paper for wrapping shredded tobacco; tipping paper (also known as tipping paper) is a special paper for connecting cigarettes and filters. The tipping paper and the filter part make up the cigarette butt. Cigarette butt refers to the remaining part of cigarette after burning. The cigarette butt is composed of the outer wrapping paper and the bundle inside the fiber filament. The fiber bundle of the cigarette butt has adsorption capacity and can eff...
