Problems solved by technology

The patent does not clearly state whether the total amount of nitrosamines in the main and side stream smoke of cigarettes has been significantly reduced, and the cost has increased due to the excessive amount of additives required
Patent CN1228945 discloses a new method of using porous material particles such as 4A zeolite to make a suspension gel solution and spraying it on cut tobacco to reduce the content of nitrosamines in cigarettes, but its pore size is limited to 0.4nm and has no combustion-supporting effect

Embodiment

[0012] Example: In order to detect the effect of the cigarette additive of the present invention on the removal of nitrosamine content in cigarette smoke, the semi-finished shredded tobacco to be rolled is taken out from the shredded tobacco storage cabinet on the shredded production line of a cigarette factory; the shredded tobacco is sprayed with the cigarette of the present invention Additives, let dry, and re-roll cigarettes with coil paper. The shredded tobacco that was not sprayed with the cigarette additive of the present invention was treated in the same way for comparison.

[0013] The present invention adopts the device and method that Caldwell reports in J.Assoc.Off.Anal.Chan., 73(5), 783,1990 to collect sidestream smoke, but changes its absorption liquid into 150mL citric acid with a pH value of 4.5 - Disodium hydrogen phosphate buffer solution. In order to observe the combustion-supporting effect more accurately, the sample smoke was kept smoldering in the cone b...

example 1

[0016] [Example 1] Dissolve 0.1051g of seaweed gel (produced by Jinzhuan Chemical Experimental Factory, the same below) into 20ml of water, heat to 40-50°C, dissolve, then add 6.0g KA zeolite (produced by Nanjing Inorganic Chemical Factory) after cooling to room temperature , the same below), stirred into a uniform suspension and sprayed on 200g of shredded tobacco A (the type of flue-cured tobacco produced in Yunnan Province, with a tar content of 15mg and a nicotine content of smoke of 1.2mg); the shredded tobacco has no change in color after drying. After being rolled into a cigarette and lit, the smoke was collected and analyzed for its nitrosamine content. In the mainstream smoke when inhaled, the content of nitrosamines decreased from 2.01nmol / cigarette to 0.67μg / cigarette, a decrease of 54.1%; the burning time decreased from 45 seconds / cigarette to 35 seconds / cigarette, a decrease of about 22%. The content of nitrosamines in cigarette smoldering smoke decreased from 29....

example 2

[0017] [Example 2] Dissolve 0.1056g of seaweed gel into 20ml of water, heat to 40-50°C, dissolve, then add 12.0g of KA zeolite after cooling to room temperature. Stir to form a uniform suspension and spray it on 200g of shredded tobacco A; the color of shredded tobacco remains unchanged after drying. After being rolled into a cigarette and lit, the smoke was collected and analyzed for its nitrosamine content. In the mainstream smoke when inhaled, the content of nitrosamines decreased from 2.01nmol / cigarette to 0.61nmol / cigarette, a reduction of 58.2%; the burning time was shortened from 45 seconds / cigarette to 35 seconds / cigarette, a decrease of about 22%. The content of nitrosamines in cigarette smoldering smoke decreased from 29.25nmol / stick to 12.77nmol / stick, a decrease of 29.0%. The smoldering time has been shortened from 20 minutes per stick to 19 minutes per stick, a reduction of 5%.

Abstract

A cigarette additives to reduce obviously the nitrosamine content in cigarette smoke and to help the combustion of the cigarette is a kind of atom with multihole such as zeolize KA suspended in the even colloid solution, especially good to use micron 3A zeolize of multihole material with grain diameter of 2-5 um and hole diameter of about 0.3 nanometre, containing with potassium ion of alkali metal ion. The invented additives can be sprayed on the cigarette scraps with the quantity as 0.5-10% of cigarettes scraps weight and to dry them in the air for producing cigarettes. The combustino time of cigarette in passive burning and inhaling burning can be shortened by 5-12% and 20-26%, separately and subsequently to reduce the nitrosamine content in smoke by 23-33% and 43-63% so as to greatly reduce the environmental pollution caused by the smoking.

Description

1. Technical field [0001] The invention relates to a shredded tobacco additive for cigarettes and its application. In particular, additives and their applications that can significantly reduce the content of nitrosamines in cigarette smoke and promote the combustion of cigarettes 2. Background technology [0002] Cigarette combustion produces mainstream and sidestream smoke. Mainstream smoke refers to the smoke inhaled by the smoker through the filter when the cigarette is inhaled and burned, while sidestream smoke refers to the smoke released directly into the air when the cigarette burns naturally, that is, smoldering. N-nitroso compounds (represented by nitrosamines) contained in cigarette smoke are highly carcinogenic. Nitrosamines in mainstream smoke directly endanger the health of smokers, while sidestream smoke from cigarettes spreads directly among the crowd, pollutes the environment and harms the health of passive smokers. Therefore, how to reduce the harm of ciga...
