Embodiment 1

[0035] Example 1 Evaluation experiment of the amount of sidestream smoke and the taste and aroma of tobacco

[0036] 1. Experimental materials

[0037] Three commercially available filter cigarettes [trade names: peace, hi-lite, seven star, manufactured by Japan Tobacco Industry Co., Ltd.] are used, and hydroxyapatite (specific surface area 80m 2 / g) and clay mixed at a ratio of 10:1, respectively, or only in shredded tobacco, or only in cigarette paper, or at the same time, mixed and adhered to 10% by weight in both shredded tobacco and cigarette paper to make filter cigarettes (experimental The numbers are No.1~No.9). The shredded tobacco used is made by removing only shredded tobacco from commercially available cigarettes and mechanically mixing them. Cigarette paper is made by spraying a mixture of hydroxyapatite and clay on the cigarette paper used for commercially available cigarettes. And, the filter used is the same filter as the commercially available cigarette.

Embodiment 2

[0045] Example 2 Evaluation experiment of the content of tar and heavy metals contained in mainstream smoke and sidestream smoke

[0046] 1. Experimental materials

[0047] Take 50 of the three commercially available filter cigarettes [trade names: peace, hi-lite, seven star, manufactured by Japan Tobacco Industry Co., Ltd.] used in Example 1 above, remove the filter, and separate the shredded tobacco from the cigarette paper. They are mixed with different additives. The specific addition is shown in Table 2. Among them:

[0048] Ordinary hydroxyapatite (abbreviation: ordinary HA) specific surface area 80m 2 / g, the crystal grain size is about 0.1μm

[0049] Calcium deficiency type hydroxyapatite (abbreviation: deficiency type HA) specific surface area 90m 2 / g, the crystal grain size is about 0.05μm

[0050] Tobacco should be used separately, and cigarette paper with a cross-sectional area of ​​5×5mm or less. The ratios in the table are weight ratios.

[0051] Source and...

Embodiment 3

[0063] Example 3 Hydroxyapatite filter cigarette

[0064] 1. Experimental materials

[0065] Take out the shredded tobacco from a commercially available filter cigarette [trade name: peace, manufactured by Japan Tobacco Sangyo Co., Ltd.], and apply a spray coating of hydroxyapatite with a weight ratio of 10 to 3 on the surface of the shredded tobacco, and re-roll the cigarette Paper, made into filter cigarettes (No. 20).

[0066] 2. Experimental methods and results

[0067] The No.20 paper cigarette was smoked by smokers and asked whether the taste and aroma were different. As a result, all 10 subjects thought that there was no significant difference in taste and aroma.

[0068] In addition, the occurrence of tributary smoke of this No.20 paper cigarette is very small, and the tributary smoke gradually decreases after being ignited and placed. After 1-2 minutes, the fire will naturally go out. It can be seen that No. 20 paper cigarettes have self-extinguishing properties.

Abstract

Disclosed is a kind of tobacco and cigarette for reducing harmful constituents, which is prepared by mixing hydroxyapatite with tobacco or attaching onto tobacco of the surface of cigarette paper, the hydroxyapatite is the common type one or calcium-loss type one, in addition, other ingredients including tricalcium phosphate and clay can also be charged. The prepared tobacco and cigarette can decrease the content of hazardous substance in the smoke.

Description

Technical field: [0001] The present invention relates to tobacco and cigarettes with reduced harmful components, in particular to tobacco and cigarettes with reduced sidestream smoke produced during smoking, and reduced tar, heavy metals and other harmful components contained in mainstream smoke and sidestream smoke. Background technique: [0002] When smoking, liquid and solid particles are dispersed in the smoke produced by tobacco. These liquid and solid particles contain a variety of substances harmful to the human body. For example, the liquid particles in the smoke contain tar components such as acetic acid, phenol, carcinogenic benzopyrene, anthracene, etc., and the solid particles contain heavy metals such as cadmium, lead, and nickel, which are small but harmful. The above-mentioned harmful substances can induce various cancers, anemic diseases, chronic bronchitis, emphysema, stomach and duodenal ulcers and other diseases. [0003] The smoke produced by tobacco is divide...
