Description

[Detailed description of the invention]

(Field of Industrial Application) The present invention provides a deodorizer that is effective and safe against unpleasant odors of food raw materials, general household odors, odors generated in industry, and other odors, and a method for producing the same. It is related to. (Conventional technology) Among the number of odor complaints, the number of complaints about household and commercial odor sources accounted for 3,789 in 1975, and 3,789 in 1975;
3,826 cases in 59 years, showing no tendency to decrease (Yoshihiro Shigeta, Relationship between the action of deodorants and odors, fragrances, 156,
75−80, 1987). Therefore, in recent years, the demand for deodorants for commercial and household use has increased, and the development of deodorants has become active. In general, deodorization methods can be roughly divided into (1) sensory deodorization methods, (2) chemical deodorization methods, (3) physical deodorization methods, (4) biological deodorization methods, and others. . However, in (1), for example, masking is performed using an aromatic substance such as a fragrance, but this method does not fundamentally eliminate odors and has the disadvantage that the odor of the masking agent itself becomes a problem. The chemical deodorization method (2) is selective to odors, making it difficult to deal with various odors, and when used in food-related applications, there are many problems in terms of the safety of the ingredients. Regarding the physical deodorization method (3) using activated carbon, etc. and the biological deodorization method (4) using enzymes, microorganisms, etc., physical deodorization methods have problems with odor selectivity and equipment. However, there are safety and other issues with biological deodorization methods. (Problems to be Solved by the Invention) The present invention solves the problems of the above-mentioned deodorizing method, and provides a safe product that can be used in a wide range of applications including food, general household use, industrial use, and others. This is a high quality deodorant and its manufacturing method. (Means for Solving the Problems) The method for producing a deodorant according to the present invention will be outlined below. As raw materials, flowers, buds, fruits, leaves, stems, skins, trees, and/or dried products of plants belonging to the genus Clara of the Fabaceae family are used. Examples of plants of the genus Clara of the Fabaceae family include Clara, Clara safflower, Japanese apricot, and others. One or more of these are thermally extracted with methanol, ethanol or other alcoholic organic solvents, glycerin, propylene glycol or other polyhydric alcoholic organic solvents, other organic solvents, water, or a mixture thereof. Although the temperature cannot be determined uniquely, for example, in the case of water, 90 to 95°C is desirable. This extract itself has a high deodorizing effect,
It can also be used as a deodorant. Additionally, 0.1 to 1 part of an adsorbent such as activated carbon, acid clay, or diatomaceous earth is added to 1 part of this extract, and the resulting treated liquid is deodorized by stirring and filtering at room temperature or under heating. It can also be used as an effective ingredient. The deodorizing components obtained before and after the decolorization treatment thus obtained may be used as they are, or may be formulated into any form depending on the purpose of deodorization. For example, to remove bad odors from toilets, garbage, etc. in the home, factories, garbage processing plants, sewage treatment plants, livestock sheds, and other places, spray a solution dissolved in ethanol or other lower alcohol solvents as is. Alternatively, it can be used as a spray. It can be used as a solution dissolved in glycerin or other polyhydric alcohol solvent, or in ethanol or other lower alcohol solvent, or by spray-drying this solution and adding it to foods, medicines, etc. as a powder product. Activated carbon is widely used as a deodorant because of its strong adsorption effect. However, the deodorizing effect of amines such as ammonia and trimethylamine is significantly inferior. The activated carbon residue, acid clay, etc. obtained by decolorizing the active ingredient with deodorizing effect obtained by thermal extraction in the present invention have a deodorizing effect on all malodorous substances including amines. There is. Therefore, not only the decolorized deodorizing solution but also the residue adsorbent can be used in the toilet as is.
Bad odors in homes such as raw garbage, factories, garbage processing plants, etc.
It can be used to remove bad odors from sewage treatment plants, livestock barns, and other places. Example 1 100g of crushed buds of apricot, a member of the Fabaceae family, Clara genus.
was extracted with 1000 g of 95°C hot water for 2 hours, and after cooling, the precipitate and liquid produced by filtration were collected. After repeating the extraction three times, add 3 parts of alcohol to 7 parts of the liquid obtained, mix well, and prepare deodorant A.
get. Example 2 The precipitate obtained in Example 1 was dried to obtain 12 g of a crude extract of Japanese apricot. Add 5 parts of glycerin to 1 part of this crude extract, and heat extraction at 200°C for 2 hours. To 13 parts of the obtained extract, 54 parts of glycerin and 33 parts of ethanol are added, mixed well and filtered to recover the liquid and obtain deodorant B. Example 3 To 10 parts of the deodorant B obtained in Example 2, 3 parts of granular activated carbon was added, stirred for 1 hour, and then filtered by suction. As a result, deodorizer C, which is a decolorized pale yellow liquid, is obtained. Example 4 0.5 part of granular activated carbon was added to 10 parts of the deodorant B obtained in Example 2, and after stirring for 1 hour, the mixture was filtered by suction. By collecting the adsorption-treated residue and drying it, deodorant D, which is activated carbon containing an active ingredient having a deodorizing effect, is obtained. Next, the effectiveness of the deodorant of the present invention will be demonstrated using experimental examples. Experimental Example 1 The deodorizing effect of the deodorant B obtained in Example 2 on trimethylamine and dimethyl sulfide was investigated using gas chromatography. 3g of 500ppm trimethylamine aqueous solution or
600ppm dimethyl sulfide aqueous solution and deodorant B5g
was placed in a 100 ml Erlenmeyer flask and stirred tightly. After 12 minutes, 3 hours, and 24 hours, 1 ml of gas from the bed space was injected into a gas chromatography system, and the residual rate of malodorous components was determined from the peak area of the obtained gas chromatogram. The results are shown in Table 1.
