Embodiment 1

[0031] The method for preparing tar extract from waste cigarette butts comprises the following steps:

[0032] (1) Pretreatment of discarded cigarette butts: tear off the outer wrapping paper of discarded cigarette butts, and cut the tow into small sections less than 1 cm in length;

[0033] (2) Add 100 g of pretreated waste cigarette butts to 1 L of petroleum ether, microwave extraction power 80 W, and microwave radiation for 5 minutes to obtain an extract;

[0034] (3) After the extract was centrifuged at 1200r / min for 2min, the supernatant was passed through a silica gel column, and the mobile phase was eluted using a mixture of petroleum ether and ethyl acetate with a volume ratio of 20:1, and the eluted components were collected;

[0035] (4) Distill the eluted fraction at 45° C. under a vacuum pressure of 1 mmH, and then dry it in vacuum at 120° C. to obtain a tar extract.

[0036] The tar extract was detected by GC / MS. The main components of the tar extract were furfur...

Embodiment 2

[0054] Example 2 Application of Tar Extract in Cigarette

[0055] The tar extract A, tar extract B, and tar extract C prepared in Example 1 were mixed at a ratio of 1:1:1 to obtain a tar characteristic flavor raw material, which was added at a ratio of 3% by weight of shredded tobacco, The obtained tar characteristic flavor raw material was added to shredded cigarette tobacco to prepare cigarette sample 1.

[0056]The tar extract A, tar extract B, and tar extract C prepared in Example 1 were mixed at a ratio of 1:2:3 to obtain a tar characteristic aroma raw material, which was added at a ratio of 5% by weight of shredded tobacco The prepared tar special flavor raw material was added to cigarette shreds to prepare cigarette sample 2.

[0057] The tar extract A, tar extract B, and tar extract C prepared in Example 1 were mixed at a ratio of 1:2:1 to obtain a tar characteristic aroma raw material, and the addition ratio was 2% by weight of shredded tobacco, The obtained tar c...

Embodiment 3

[0062] Example 3 Selection of preparation method conditions

[0063] 1. Selection of extraction solvent

[0064] Use methanol, dichloromethane, absolute ethanol, glycerin, petroleum ether, and polyethylene glycol 400 to extract the pretreated waste cigarette butts, the ratio of solid to liquid is 1:10 (g / mL), and the microwave extraction power is 80W. The microwave radiation extraction time was 5 minutes, and the extraction was performed once. The influence of different solvents on the extraction effect (the content of components extracted per g of cigarette butts) was compared and analyzed. The test results of the extract solution 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 tar extract from waste cigarette butts and application of the tar extract in cigarettes. The method comprises the following steps: (1) adding waste cigarette butts into an extraction solvent for microwave extraction to obtain extract liquor; and (2) centrifuging the extract liquor, carrying out silica gel column chromatography on a supernatant, eluting by using a mixed solution of petroleum ether and ethyl acetate as a mobile phase, and collecting an eluted component to obtain the tar extract. Waste cigarette butts are used as raw materials, andtar substances in the cigarette butts are extracted; by microwave-assisted extraction and silica gel column chromatography separation, harmful substances in cigarette butt tar are removed, and the component with aroma characteristics is reserved; by applying the tar extract to low-end cigarettes, the aroma, smoke and taste characteristics of the low-end cigarettes are improved, the sensory qualityof the low-end cigarettes is improved, the use ratio of inferior tobacco leaves in the cigarettes is increased or the use way of the inferior tobacco leaves is widened, and thought and technical support are provided for relieving the inventory pressure of the inferior tobacco leaves.

Description

technical field [0001] The invention relates to a method for preparing tar extract from waste cigarette butts and its application in cigarettes, belonging to the technical field of tobacco technology. Background technique [0002] Cigarettes are 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 butts are the remaining parts of cigarettes after they are smoked. The cigarette butt is composed of the outer newspaper of the outer layer and the bundle inside the fiber filament. The fiber filament bundle of the cigarette butt has adsorption capacity and can effectively t...
