[0029] Example 1 Preparation of tar extract
[0030] A method for preparing a tar extract with aroma-causing properties from waste cigarette butts, comprising the following steps:
[0031] (1) Pretreatment of discarded cigarette butts: tear off the tipping paper of discarded cigarette butts, and cut the fiber tow part into small sections less than 1 cm long;
[0032] (2) Mix 100g of pretreated waste cigarette butts and 1L of 75% (v / v) ethanol solution in an ultra-high pressure PE bag, put the PE bag in an autoclave, pressurize to 300MPa, keep it for 10min, and release the pressure Time 10s, obtain extract;
[0033] (3) The extract was centrifuged at 1000r / min for 2min, the supernatant was concentrated by vacuum distillation, the temperature was controlled at 35°C, the pressure was 2mmH, and steamed until no fraction was distilled to obtain a tar extract.
[0034] The tar extract obtained was detected by GC / MS, and the components of the tar extract obtained were furfural, fu...

[0052] Example 2 Aroma-inducing properties of cigarette tar extract
[0053] The tar extract prepared in Example 1 was added to the filter auxiliary material of heat-not-burn cigarettes at an addition rate of 3% by weight of heat-not-burn cigarettes to prepare heat-not-burn cigarette sample A (HnB sample A).
[0054] The tar extract prepared in Example 1 was added to the condensation auxiliary material of the heat-not-burn cigarette at an addition ratio 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 3% 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 humidity environme...
Embodiment 3
[0060] Example 3 Selection of preparation method conditions
[0061] 1. Selection of ultra-high pressure extraction pressure
[0062] Mix 20g of pretreated waste cigarette butts and 200mL of 75% (v / v) ethanol solution into a high-pressure PE bag, and extract waste cigarette butts at 200MPa, 300MPa, 400MPa, and 500MPa respectively. The extraction time is 10min. Both are 10S. The influence of different pressures on the extraction effect was compared and analyzed. The test results of the extract are shown in Table 2. As can be seen from Table 2, 75% (v / v) aqueous ethanol has the best effect of extracting the tar extract at 300MPa.
[0063] Extraction effect (mg / g) under different pressures of table 2
[0064]
[0065] 2. Selection of holding time
[0066] Mix 20 g of pretreated waste cigarette butts and 200 mL of 75% (v / v) ethanol aqueous solution into a high-pressure PE bag, extract waste cigarette butts at 300 MPa for 6 min, 8 min, 10 min, and 12 min, respectively, and ...
