Embodiment 1

[0032] Example 1 Extraction of tar extract with aroma-inducing properties from waste cigarette butts

[0033] A method of utilizing waste cigarette butts to prepare a tar extract with aroma-causing properties, comprising the following steps:

[0034] (1) pretreatment of discarded cigarette butts: tear off the tipping paper of discarded cigarette butts, remove residual tobacco shreds and cigarette paper, collect fiber tow, and cut the tow into small sections less than 1 cm long;

[0035] (2) put 20g of processed waste cigarette butts in the subcritical extraction tank, inject 800mL of n-butane, carry out subcritical extraction, extraction pressure 1.0MPa, extraction temperature 40 ℃, extraction time is 70min, extract once, obtain extraction liquid;

[0036] (3) after the extract is vacuum filtered, the filtrate is distilled under reduced pressure at 30°C under 0.07Mpa conditions to obtain concentrated extract;

[0037] (4) the concentrated extract is carried out two-stage mo...

Embodiment 2

[0056] Example 2 Applying tar extract to cigarettes

[0057] The cigarette tar extract prepared in Example 1 was added to the cigarette filter tip at a proportion of 2% by weight of the cigarette, to prepare a cigarette sample A with tar aroma components added.

[0058] The cigarette tar extract prepared in Example 1 was added to the shredded cigarette in a proportion of 2% of the weight of the cigarette, to prepare a cigarette sample B with tar aroma components added.

[0059] The cigarette tar extract prepared in Example 1 was added to the shredded cigarette in a proportion of 3% of the weight of the cigarette, to prepare a cigarette sample C with tar aroma components added.

[0060] After equilibrating the cigarette samples prepared by the above scheme and the cigarettes without adding tar aroma components in a constant temperature and humidity environment of (20 ± 1) ℃ and relative humidity of (60 ± 3)% for 24 hours, 10 or more people were organized to evaluate the smoki...

Embodiment 3

[0064] Example 3 Selection of preparation method conditions

[0065] 1. Selection of extraction pressure

[0066] Weigh 20g of the treated waste cigarette butts, add them into a subcritical extraction tank, and then inject 800 mL of n-butane into the extraction tank. The waste cigarette butts were extracted subcritically under MPa, and the extraction was performed once for 70 minutes. The effects of different extraction pressures on the extraction effect were compared and analyzed. The test results are shown in Table 2. It can be seen from Table 2 that the extraction effect at 1.0 MPa is the best.

[0069] 2. Selection of subcritical extraction temperature

[0070] Weigh 20 g of the treated waste cigarette butts, add them into a subcritical extraction tank, and then inject 800 mL of n-butane into the extraction tank. The extraction pressure is set to 1.0 MPa, and the extraction tempera...

Abstract

The invention provides a method for preparing a tar extract with aroma characteristic by using waste cigarette butts, comprising the following steps: (1) adding waste cigarette butts into an extraction solvent for subcritical extraction to obtain an extraction solution; (2) carrying out vacuum filtration on the extraction solution, and carrying out reduced pressure distillation on a filtrate to obtain a concentrated extract; and (3) carrying out molecular distillation on the concentrated extract, and collecting molecular distillation light components to obtain the tar extract with the aroma characteristic. Through subcritical extraction and molecular distillation separation for preparation of the tar extract, harmful substances in tar are removed, and aroma components of the tar are reserved; when the tar extract is applied to cigarettes, the aroma, smoke and taste characteristics of cigarettes are improved, thus providing an effective way for widening the application range and usage quantity of low-grade tobacco leaves in medium-end and low-end cigarettes. By optimizing the conditions of subcritical extraction and molecular distillation separation, the tar extract with higher extraction rate is obtained from cigarette butts.

Description

technical field [0001] The invention relates to a method for preparing a tar extract with aroma-inducing properties by using waste cigarette butts and its application in cigarettes, and belongs to the technical field of tobacco technology. Background technique [0002] Cigarette butt is a by-product of cigarette consumption, mainly composed of filter rod, residual tobacco, cigarette paper, tipping paper, etc. my country is a big country in the production and consumption of cigarettes. With a large number of cigarettes consumed every year, a lot of discarded cigarette butts are produced, which are thrown away and pollute the environment. The tar substances retained in discarded cigarette butts contain not only ketones, furans, pyrazines and other aroma components that have a positive effect on sensory quality, but also nicotine, which can improve consumers' physiological satisfaction, as well as amines and aldehydes. and other harmful substances that have a significant negat...
