Description

200406161 Description of the invention [Technical field to which the invention belongs] The present invention relates to an aldehyde-containing cigarette filter that can reduce the mainstream smoke of cigarettes. , 3 miles [prior art] The mainstream smoke that smokers emit when they smoke contains various chemical components. The aldehydes represented by amidaldehyde among other chemical ingredients are difficult to be absorbed and removed by ordinary fragrances: filters. Therefore, it is desired to remove aldehydes from mainstream cigarettes. In the past, attempts have been made to use various additives in cigarette filters to absorb and remove aldehydes contained in mainstream cigarettes. However, the use of conventional additions: will cause a problem of weakening the taste of grass. [Disclosure of the Invention] An object of the present invention is to provide a cigarette filter which can effectively reduce the aldehyde content in mainstream cigarettes of cigarettes while suppressing adverse effects such as weakening the taste of grass cultivation. A cigarette filter according to the object of the present invention is characterized by including a filter medium containing a basic amino acid or a basic amino acid salt and a humectant. The test amino acid or test amino acid used in the present invention is selected from the group consisting of arginine, spermine, lysine, lysine, histamine, histamine, ursine , Ornithine, citrulline, citrulline, hydroxyzine, and transazine The humectant used in the present invention is selected from the group consisting of glycerin, sodium propionate and sodium lactate. In the cigarette filter of the present invention, the required content of the basic amino acid or basic amino acid salt is 3.5 mg or more. 315057 200406161 I < The presently specified cigarette filter, the ratio of the required amino acid or amino acid salt to the retainer is between 1 ·· 1 and 1 ·· 2 . [Performance method] d. Introduced in-depth research on additives from various viewpoints to reduce the results of the main ingredients contained in cigarettes. The inventors found that the amino acid or the acidity = acid salt is effective. Additives. The test amino acid or test compound used in the present invention is selected from the group consisting of arginine, arginine, lysine, amine, histamine, histamine , Uramine, uramine, citrulline, citrulline, triazine and triazine salt. Among these compounds, ' arginine and its salts are recognized as food additives. The inventors have also discovered that the use of an amino acid or an amino acid salt in combination with a retainer will more effectively remove the acids contained in the mainstream smoke of a cigarette. The manganese used in the present invention is a group consisting of n-white & saccharin, glycerin, sodium propionate and sodium lactate. Ordinary pass media such as ga acid hemp fiber, paper filter material or pulp non-woven fabric can be used as the test amino acid or basic amino acid salt and tincture (filter material). a. It is believed that in the cigarette filter of the present invention, the acid in mainstream cigarettes is reduced by the mechanism provided below. In the first step, the aldehydes contained in the mainstream cigarettes of the cigarette are dissolved in the moisture-retaining agent held by the filter: the moisture content. In addition, the water-soluble species of warfare react with the amino acid or basic amino acid salt carried by the filter to be trapped in the filter. To note, humectants are used to stably maintain the moisture responsible for dissolving aldehydes. In the cigarette filter of the present invention, the content of the basic amino acid or the test amino acid salt 315057 6 200406161 should be 3.5 mg or more, because when the content is less than 35 mg, it is difficult to obtain the effect of sufficiently reducing aldehydes. In addition, in the cigarette filter of the present invention, the ratio of the specified basic amino acid or basic amino acid salt to the fishing agent must fall between 1 ·· 1 and 1: 2. If the above ratio does not fall within the above range, it will be difficult to obtain a sufficient effect of reducing aldehydes. In order to filter the media to contain an amino acid or an amino acid and a base agent, a method such as spraying, dipping, and roller transfer can be used. In addition to basic amino acids or basic amino salts and humectants, the filter media may also contain activated carbon. The structure of the cigarette filter may be a common type, a two-stage type, a multi-stage type containing three or more sections, or a stuffer-spacer-stuffer type. The basic amino acid or basic amino acid salt and humectant may be contained in part or all of the segments of the cigarette filter. The cigarette filter of the present invention may be a filter attached to a tobacco segment of a cigarette as an oral end assembly or in the form of a mouthpiece. Examples: 8 kinds of constituents composed of n. In each of the following examples of taking the knife, the explanation will be directed to the osmic acid among the acids (prisyl compounds) to be measured. In the method for measuring the aldehydes contained in the mainstream cigarettes of cigarettes used in the following examples, high-speed liquid chromatography (HPLC) was used to measure the 2,4-dinitrobenzene (DNPH) organisms and capture substances . The substances that can be measured simultaneously by this method are acetaldehyde, acetaldehyde, acetone, acrolein 'propanal, butenal, acetophenone, and hydrazine (DNPH) in the first step in the capture solution. g of 2, acetonitrile with dinitro L, and then added 5.6 mL of 60% over 315057 200406161 i-· chloric acid, and then the resulting solution was diluted to 2 ethyl with ultrapure water.
