Description

本発明は、抗菌性水溶液に関し、特にホタテ貝殻水溶液の抗菌効果を十分に発揮させることができる抗菌性水溶液に関する。 The present invention relates to an antibacterial aqueous solution, and more particularly to an antibacterial aqueous solution that can sufficiently exhibit the antibacterial effect of a scallop shell aqueous solution.

ホタテ貝殻はＣａＣＯ_３を主成分としているが、このホタテ貝殻を焼成し粉砕した粉体からなるホタテ貝殻セラミックを水に溶いたホタテ貝殻粉体水溶液はＣａ（ＯＨ）_２を主成分としていて、このＣａ（ＯＨ）_２を主成分とするこのホタテ貝殻粉体水溶液には強い抗菌効果があることが、従来知られている（例えば、特許文献１参照）。 The scallop shell is mainly composed of CaCO ₃ , but the scallop shell powder aqueous solution in which the scallop shell ceramic made of the powder obtained by firing and pulverizing this scallop shell is dissolved in water contains Ca (OH) ₂ as the main component. It has been conventionally known that this scallop shell powder aqueous solution containing Ca (OH) ₂ as a main component has a strong antibacterial effect (see, for example, Patent Document 1).

特開２００５−１２００１３号公報JP 2005-120013 A

しかしながら、ホタテ貝殻を焼成し粉砕した粉体には腐敗臭の原因となる有機物質が残存し、この有機物質によりホタテ貝殻粉体水溶液中には菌が発生しやすくなっている。そのため、ホタテ貝殻粉体水溶液の抗菌効果は、その有機物質が原因の菌を除去するのに用いられるため、ホタテ貝殻粉体水溶液の抗菌効果を十分に発揮させることができないという問題があった。 However, an organic substance causing caustic odor remains in the powder obtained by baking and pulverizing scallop shells, and this organic substance tends to cause bacteria in the aqueous solution of scallop shell powder. Therefore, since the antibacterial effect of the aqueous solution of scallop shell powder is used to remove bacteria caused by the organic substance, there is a problem that the antibacterial effect of the aqueous solution of scallop shell powder cannot be sufficiently exhibited.

本発明は、このような問題点に着目してなされたもので、ホタテ貝殻粉体水溶液の抗菌効果を十分に発揮させることができる抗菌性水溶液を提供することを目的としている。 The present invention has been made paying attention to such problems, and an object thereof is to provide an antibacterial aqueous solution capable of sufficiently exhibiting the antibacterial effect of the scallop shell powder aqueous solution.

前記課題を解決するために、本発明の抗菌性水溶液は、ホタテ貝殻を焼成して粉砕した粉体が投入された水溶液を、炭に接触させて得られることを特徴としている。
この特徴によれば、ホタテ貝殻を焼成して粉砕した粉体に残存している有機物質が炭に吸着されるため、ホタテ貝殻粉体水溶液中に有機物質が残存することなくその有機物質が原因の菌が発生しないので、ホタテ貝殻粉体水溶液の抗菌効果を十分に発揮させることができる。さらに、ホタテ貝殻を焼成して粉砕した粉体に残存している有機物質が炭に吸着されるため、ホタテ貝殻粉体水溶液の消臭効果が高まることが確認できた。 In order to solve the above-mentioned problems, the antibacterial aqueous solution of the present invention is obtained by bringing an aqueous solution charged with powder obtained by firing and pulverizing scallop shells into contact with charcoal.
According to this feature, the organic substance remaining in the powder obtained by firing and pulverizing the scallop shell is adsorbed by the charcoal, so that the organic substance does not remain in the aqueous solution of the scallop shell powder. Therefore, the antibacterial effect of the scallop shell powder aqueous solution can be sufficiently exerted. Furthermore, it was confirmed that the deodorizing effect of the aqueous solution of scallop shell powder was enhanced because the organic substance remaining in the powder obtained by firing and pulverizing the scallop shell was adsorbed by charcoal.

前記炭は、透過性紙製袋に封入され前記粉体が投入された水溶液中に所定時間浸されていることが好ましい。
この特徴によれば、水溶液中に残存しているホタテ貝殻を焼成して粉砕した粉体に残存している有機物質は、所定時間透過性紙製袋を透過して炭に吸着されるため、ホタテ貝殻粉体水溶液中に有機物質が残存することなくその有機物質が原因の菌が発生しないので、ホタテ貝殻粉体水溶液の抗菌効果をより十分に発揮させることができる。 The charcoal is preferably immersed in an aqueous solution filled with a permeable paper bag and charged with the powder for a predetermined time.
According to this feature, the organic substance remaining in the powder obtained by firing and pulverizing the scallop shell remaining in the aqueous solution passes through the permeable paper bag for a predetermined time and is adsorbed by the charcoal. Since the organic substance does not remain in the scallop shell powder aqueous solution and the bacteria caused by the organic substance does not occur, the antibacterial effect of the scallop shell powder aqueous solution can be more fully exhibited.

前記粉体は、前記ホタテ貝殻を約８００℃で２時間程度加熱焼成が行われ、粒径約２００μｍに粉砕されたものであることが好ましい。
この特徴によれば、ホタテ貝殻を約８００℃で３時間以上加熱焼成が行われると、ホタテ貝殻粉体に残存する有機物質も消滅しホタテ貝殻粉体水溶液中に菌が発生することがなくなる一方、ホタテ貝殻粉体の機能物質の抗菌効果も損なわれてしまうこととなるが、ホタテ貝殻を約８００℃で２時間程度加熱焼成が行われると、前記有機物質が残存するものの、ホタテ貝殻粉体の機能物質の抗菌効果が損なわれることはない。 The powder is preferably obtained by baking the scallop shell at about 800 ° C. for about 2 hours and pulverizing to a particle size of about 200 μm.
According to this feature, when the scallop shell is heated and baked at about 800 ° C. for 3 hours or more, the organic substance remaining in the scallop shell powder disappears and bacteria are not generated in the aqueous solution of scallop shell powder. The antibacterial effect of the functional substance of the scallop shell powder is also impaired, but when the scallop shell is heated and baked at about 800 ° C. for about 2 hours, the organic substance remains, but the scallop shell powder The antibacterial effect of the functional substance is not impaired.

前記炭は、ペーパー類が酸素を絶った状態において６５０〜８００℃で炭化されたペーパー炭であることが好ましい。
この特徴によれば、ペーパー炭は多くの微細気孔を有し、平均比表面積が２００ｍ^２／ｇ以上と極めて高い値を示すので、ホタテ貝殻粉体に残存する有機物質の吸着を短時間で効率良く行うことができる。 The charcoal is preferably paper charcoal that has been carbonized at 650 to 800 ° C. in a state where the paper is oxygen-free.
According to this feature, paper charcoal has many fine pores and an average specific surface area of 200 m ² / g or more, which is extremely high, so that the adsorption of organic substances remaining in the scallop shell powder is efficient in a short time. Can be done well.

本発明に係る抗菌性水溶液及びその生成方法を実施するための形態を実施例に基づいて以下に説明する。 EMBODIMENT OF THE INVENTION The form for implementing the antimicrobial aqueous solution which concerns on this invention, and its production | generation method is demonstrated below based on an Example.

（第１実施例）
図１（ａ）に示すように、ホタテ貝殻１は、焼成装置（図示せず）により約８００℃で２時間程度加熱焼成が行われ、既存の粉砕装置により粒径約２００μｍに粉砕され、ホタテ貝殻粉体２となる。ホタテ貝殻１を約８００℃で３時間以上加熱焼成が行われると、ホタテ貝殻粉体２に残存する有機物質も消滅しホタテ貝殻粉体水溶液中に菌が発生することがなくなる一方、ホタテ貝殻粉体２の機能物質の抗菌効果も損なわれてしまうこととなるが、ホタテ貝殻１を約８００℃で２時間程度加熱焼成が行われると、前記有機物質が残存するものの、ホタテ貝殻粉体２の機能物質の抗菌効果が損なわれることはなくなるのである。また図１（ｂ）に示すように、ペーパー類としての新聞紙３は、炭化装置（図示せず）の炭化室に入れられ、炭化室内に燃焼室から高温の燃焼ガスを導入して、酸素を絶った状態の炭化室内を６５０〜８００℃に加熱することにより炭化されてペーパー炭４が生成される。これによりペーパー炭４は、多くの微細気孔を有するうえに、その微細気孔を含め全体にタール分が残留せず、純粋な炭素構造を有することとなる。その結果、ペーパー炭４は、平均比表面積が２００ｍ^２／ｇ以上と極めて高い値を示し、優れた吸着性能を発揮することができる。炭化温度を６５０〜８００℃とする理由は、６５０℃未満では、得られる炭化物にタール分が残留して、純粋な炭素構造が得られず、従って平均比表面積も２００ｍ^２／g未満と低くなるからである。また、８００℃を超える高温にすることはコストの上昇を招き経済的に不利である。 (First embodiment)
As shown in FIG. 1 (a), the scallop shell 1 is heated and fired at about 800 ° C. for about 2 hours by a baking apparatus (not shown), and is pulverized to a particle size of about 200 μm by an existing pulverizer. Shell powder 2 is obtained. When the scallop shell 1 is heated and baked at about 800 ° C. for 3 hours or more, organic substances remaining in the scallop shell powder 2 disappear, and no bacteria are generated in the scallop shell powder aqueous solution. Although the antibacterial effect of the functional substance of the body 2 is also impaired, when the scallop shell 1 is heated and baked at about 800 ° C. for about 2 hours, the organic substance remains, but the scallop shell powder 2 The antibacterial effect of the functional substance will not be impaired. As shown in FIG. 1 (b), newspaper 3 as paper is put in a carbonization chamber of a carbonization device (not shown), and high-temperature combustion gas is introduced into the carbonization chamber from the combustion chamber, and oxygen is supplied. By heating the carbonized chamber in an isolated state to 650 to 800 ° C., the carbonized carbon is produced. As a result, the paper charcoal 4 has many fine pores, and the tar content does not remain on the whole including the fine pores, and has a pure carbon structure. As a result, the paper charcoal 4 exhibits an extremely high value with an average specific surface area of 200 m ² / g or more, and can exhibit excellent adsorption performance. The reason for setting the carbonization temperature to 650 to 800 ° C. is that if the temperature is less than 650 ° C., a tar content remains in the obtained carbide, and a pure carbon structure cannot be obtained, and thus the average specific surface area is also reduced to less than 200 m ² / g. Because. In addition, a high temperature exceeding 800 ° C. causes an increase in cost and is economically disadvantageous.

図２に示すように、透過性紙製袋５は平面視矩形状を成しており、この袋５には前記ペーパー炭４が入れられ、その開口は適宜手段により封止される。透過性紙製袋５は、木材パルプ及び非木材パルプが配合されて抄紙される原紙から構成されており、透過性紙製袋５の内面６は、クレープ加工によって皺状に形成され、内面６の表面積が増大されている。したがって、後記するようにペーパー炭４を封入した透過性紙製袋５を水槽７内の水８に浸すと、ペーパー炭４の黒ずみは内面６に効率的に吸着され、水槽７内の水８が黒ずむことはない。 As shown in FIG. 2, the transparent paper bag 5 has a rectangular shape in plan view. The bag 5 is filled with the paper charcoal 4, and the opening thereof is appropriately sealed. The permeable paper bag 5 is made of a base paper that is made by mixing wood pulp and non-wood pulp. The inner surface 6 of the permeable paper bag 5 is formed into a bowl shape by creping, and the inner surface 6 The surface area of the is increased. Therefore, as described later, when the permeable paper bag 5 enclosing the paper charcoal 4 is immersed in the water 8 in the water tank 7, the darkening of the paper charcoal 4 is efficiently adsorbed on the inner surface 6, and the water 8 in the water tank 7 is absorbed. Will not darken.

次に本発明の抗菌性消臭剤水溶液の生成方法について説明する。まず、透過性紙製袋５にペーパー炭４を入れて開口を封止する。次に、ペーパー炭４を封入した透過性紙製袋５とホタテ貝殻粉体２とを水８が入った水槽７内に入れて６時間以上浸す。その際、ホタテ貝殻粉体２の腐敗臭の原因となる有機物質は透過性紙製袋５を透過して透過性紙製袋５に封入されたペーパー炭４に吸着される。したがって、水溶液中に有機物質が残存することなくその有機物質が原因の菌が発生しないので、ホタテ貝殻粉体２の機能物質の抗菌効果を十分に発揮させることができる。そしてその水溶液を３０分程イオン発生装置（図示せず）にかけて、その後ろ過装置（図示せず）によりろ過することにより、本発明の抗菌性溶液が生成される。 Next, the production | generation method of the antibacterial deodorant aqueous solution of this invention is demonstrated. First, the paper charcoal 4 is put in the permeable paper bag 5 to seal the opening. Next, the permeable paper bag 5 enclosing the paper charcoal 4 and the scallop shell powder 2 are placed in a water tank 7 containing water 8 and immersed for 6 hours or more. At that time, the organic substance causing the rot odor of the scallop shell powder 2 passes through the permeable paper bag 5 and is adsorbed by the paper charcoal 4 enclosed in the permeable paper bag 5. Therefore, since the organic substance does not remain in the aqueous solution and the bacteria caused by the organic substance is not generated, the antibacterial effect of the functional substance of the scallop shell powder 2 can be sufficiently exhibited. And the antibacterial solution of this invention is produced | generated by applying the aqueous solution to an ion generator (not shown) for about 30 minutes, and filtering with a filtration apparatus (not shown) after that.

（第２実施例）
第１実施例では、透過性紙製袋５にはペーパー炭４を封入したが、第２実施例では透過性紙製袋５に竹炭（図示せず）を封入した。本発明の抗菌性水溶液の生成方法については第１実施例と同じである。 (Second embodiment)
In the first example, the paper charcoal 4 was enclosed in the permeable paper bag 5, but in the second example, bamboo charcoal (not shown) was enclosed in the permeable paper bag 5. The method for producing the antibacterial aqueous solution of the present invention is the same as in the first embodiment.

次に、本発明の抗菌性水溶液が十分な抗菌効果を発揮することを実験で確認を行った。 Next, it was confirmed by experiments that the antibacterial aqueous solution of the present invention exhibits a sufficient antibacterial effect.

そこで、まず、透過性紙製袋５にペーパー炭４を封入した本発明の第１実施例の抗菌性水溶液（検体１）、及び透過性紙製袋５に竹炭を封入した本発明の第２実施例の抗菌性水溶液（検体２）の抗菌効果をホタテ貝殻粉体２水溶液（対照１）、ペーパー炭４水溶液（対照２）、及び竹炭水溶液（対照３）と比較して抗菌効果の確認を行った。試験概要は以下のとおりである。

Test method Specimen 1, Specimen 2, Control 1, Control 2, and Control 3 were added to the co-test bacteria culture solution and incubated, and the test solution was removed over time from 0 to 10 minutes and applied to an agar plate medium. The viable cell rate was determined from the colony coefficient after 24 hours of culture. LB agar plate medium is used as the medium. The insulation temperature is 37 ° C.
5). Test Results The viable cell rates of Escherichia coli, Salmonella and Staphylococcus aureus in Sample 1 are shown in [Table 2], the viable cell rates of Escherichia coli, Salmonella and Staphylococcus aureus in Sample 2 are shown in [Table 3], and Escherichia coli and Salmonella in Control 1 The viable cell rates of Staphylococcus aureus in [Table 4], the viable cell rates of Escherichia coli, Salmonella, and Staphylococcus aureus in Control 2 in [Table 5], and the viable cell rates of Escherichia coli, Salmonella and Staphylococcus aureus in Control 3. Are shown in [Table 6]. A graph showing the viability of E. coli samples 1, 2, 2, 3, and 3 is shown in [FIG. 4]. Sample 1, sample 2, control 1, control 2, and control 3 Salmonella [Fig. 5] and a graph showing the viability rate of Staphylococcus aureus in Specimen 1, Specimen 2, Control 1, Control 2, and Control 3 are shown in [FIG. 6], respectively. .

大腸菌の生菌率に関しては［表２］〜［表５］、及び［図４］に示すように、検体１では試験開始直後（０分）で生菌率は３６％になり、１分で生菌率は０．４％に、５分で生菌率は１０^−３％以下に、１０分で生菌率は１０^−４％以下になった。また、検体２では試験開始直後（０分）で生菌率は４５％になり、１分で生菌率は５％に、５分、１０分で生菌率は２％になった。一方、対照１では試験開始直後（０分）で生菌率は５０％になり、１分で生菌率は１０％に、５分、１０分で生菌率は５％になった。また対照２及び対照３では生菌率は１００％のままである。これにより、検体１及び検体２とも対照１より大腸菌の生菌率は低い値を示すことが確認できた。これは、ホタテ貝殻粉体２の抗菌効果を阻害している有機物質がペーパー炭または竹炭に吸着されるため、ホタテ貝殻粉体２の抗菌効果が十分発揮できたものによるものである。また検体１の方が検体２より大腸菌の生菌率に関して低い値を示すのは、ホタテ貝殻粉体２の有機物質の吸着能力が竹炭よりペーパー炭４の方が高いためである。また、対照２及び対照３では抗菌効果は全く得られなかった。 As shown in [Table 2] to [Table 5] and [FIG. 4] regarding the viable cell rate of Escherichia coli, the viable cell rate was 36% immediately after the start of the test (0 minute) in Sample 1, and in 1 minute. Namakinritsu is 0.4%, viable cell ratio is ^{10 -3%} or less in 5 minutes, the viable cell ratio at 10 minutes became ^{10 -4%} or less. In specimen 2, the viable cell rate was 45% immediately after the start of the test (0 minute), the viable cell rate was 5% in 1 minute, and the viable cell rate was 2% in 5 minutes and 10 minutes. On the other hand, in Control 1, the viable cell rate was 50% immediately after the start of the test (0 minutes), the viable cell rate was 10% in 1 minute, and the viable cell rate was 5% in 5 minutes and 10 minutes. In the control 2 and the control 3, the viable cell rate remains 100%. Thereby, it was confirmed that the viable cell rate of E. coli was lower than that of Control 1 in both Sample 1 and Sample 2. This is because the organic substance that inhibits the antibacterial effect of the scallop shell powder 2 is adsorbed on paper charcoal or bamboo charcoal, so that the antibacterial effect of the scallop shell powder 2 can be sufficiently exhibited. The reason why the specimen 1 shows a lower value regarding the viability of Escherichia coli than the specimen 2 is that the paper charcoal 4 has a higher ability to adsorb organic substances in the scallop shell powder 2 than the bamboo charcoal. Further, the antibacterial effect was not obtained at all in Control 2 and Control 3.

サルモネラ菌の生菌率に関しては［表２］〜［表５］、及び［図５］に示すように、検体１では試験開始直後（０分）で生菌率は２２％になり、１分で生菌率は１０^‐２％以下に、５分、１０分で生菌率は１０^−４％以下になった。また、検体２では試験開始直後（０分）で生菌率は３０％になり、１分で生菌率は２％に、５分、１０分で生菌率は１％になった。一方、対照１では試験開始直後（０分）で生菌率は４０％になり、１分で生菌率は８％に、５分、１０分で生菌率は６％になった。また対照２及び対照３では生菌率は１００％のままである。これにより、検体１及び検体２とも対照１よりサルモネラ菌の生菌率は低い値を示すことが確認できた。これは、前述した如く、ホタテ貝殻粉体２の抗菌効果を阻害している有機物質がペーパー炭４または竹炭に吸着されるため、ホタテ貝殻粉体２の抗菌効果が十分発揮できたものによるものである。また検体１の方が検体２よりサルモネラ菌の生菌率に関して低い値を示すのも、前述した如く、ホタテ貝殻粉体２の有機物質の吸着能力が竹炭よりペーパー炭４の方が高いためである。また、対照２及び対照３では抗菌効果は全く得られなかった。 Regarding the viability rate of Salmonella, as shown in [Table 2] to [Table 5] and [FIG. 5], in Sample 1, the viable cell rate was 22% immediately after the start of the test (0 minutes), and in 1 minute. Namakinritsu the ^10-2% or less, 5 minutes, the viable cell ratio at 10 minutes became ^{10 -4%} or less. In sample 2, the viable cell rate was 30% immediately after the start of the test (0 minute), the viable cell rate was 2% in 1 minute, and the viable cell rate was 1% in 5 minutes and 10 minutes. On the other hand, in Control 1, the viable cell rate was 40% immediately after the start of the test (0 minute), the viable cell rate was 8% in 1 minute, and the viable cell rate was 6% in 5 minutes and 10 minutes. In the control 2 and the control 3, the viable cell rate remains 100%. Thereby, it was confirmed that the viable cell rate of Salmonella was lower than that of Control 1 in both Sample 1 and Sample 2. This is because, as described above, the organic substance that inhibits the antibacterial effect of the scallop shell powder 2 is adsorbed on the paper charcoal 4 or bamboo charcoal, so that the antibacterial effect of the scallop shell powder 2 is sufficiently exhibited. It is. Also, the reason why the specimen 1 shows a lower value regarding the viability of Salmonella than the specimen 2 is because, as described above, the paper charcoal 4 has a higher ability to adsorb organic substances in the scallop shell powder 2 than the bamboo charcoal. . Further, the antibacterial effect was not obtained at all in Control 2 and Control 3.

黄色ブドウ球菌に関しては［表２］〜［表５］、及び［図６］に示すように、検体１では試験開始直後（０分）で生菌率は６２％になり、１分で生菌率は０．６％に、５分、１０分で生菌率は１０^−４％以下になった。また検体２では試験開始直後（０分）で生菌率は７０％になり、１分で生菌率は５％に、５分、１０分で生菌率は３％になった。一方、対照１では試験開始直後（０分）で生菌率は７５％になり、１分で生菌率は１５％に、５分、１０分で生菌率は１２％になった。また対照２及び対照３では生菌率は１００％のままである。検体１及び検体２とも対照１より黄色ブドウ球菌の生菌率は低い値を示すことが確認できた。これは、前述した如く、ホタテ貝殻粉体２の抗菌作用を阻害している腐敗臭の原因となる有機物がペーパー炭４または竹炭に吸着されるため、ホタテ貝殻粉体２の抗菌効果が十分発揮できたものによるものである。また検体１の方が検体２より黄色ブドウ球菌の生菌率に関して低い値を示すのも、前述した如く、ホタテ貝殻粉体２の有機物質の吸着能力が竹炭よりペーパー炭４の方が高いためである。また、対照２及び対照３では抗菌効果は全く得られなかった。 Regarding S. aureus, as shown in [Table 2] to [Table 5] and [FIG. 6], in the specimen 1, the viable cell rate was 62% immediately after the start of the test (0 min), and the viable cells in 1 min The rate was 0.6%, and the viable cell rate was ^10-4 % or less in 5 minutes and 10 minutes. In specimen 2, the viable cell rate was 70% immediately after the start of the test (0 minute), the viable cell rate was 5% in 1 minute, and the viable cell rate was 3% in 5 minutes and 10 minutes. On the other hand, in Control 1, the viable cell rate was 75% immediately after the start of the test (0 minute), the viable cell rate was 15% in 1 minute, and the viable cell rate was 12% in 5 minutes and 10 minutes. In the control 2 and the control 3, the viable cell rate remains 100%. It was confirmed that the viable cell rate of Staphylococcus aureus was lower than that of Control 1 in both Sample 1 and Sample 2. This is because, as mentioned above, the organic matter causing the rot odor that inhibits the antibacterial action of the scallop shell powder 2 is adsorbed by the paper charcoal 4 or bamboo charcoal, so that the antibacterial effect of the scallop shell powder 2 is sufficiently exerted. It depends on what was made. In addition, specimen 1 shows a lower value for the viability of Staphylococcus aureus than specimen 2 because, as described above, paper charcoal 4 has a higher ability to adsorb organic substances in scallop shell powder 2 than bamboo charcoal. It is. Further, the antibacterial effect was not obtained at all in Control 2 and Control 3.

It was confirmed that it was 14.2 ppm after minutes, and 14.5 ppm after 6 minutes, 8 minutes, and 10 minutes. In the control 1, the gas concentration increases with the lapse of time, which is caused by the fact that the organic substance of the scallop shell powder 2 gives off a rotten odor. In addition, in the paper charcoal 4 aqueous solution as the control 2, after 2 minutes, it is 13.1 ppm, after 4 minutes it is 12.5 ppm, after 6 minutes it is 12.0 ppm, after 8 minutes it is 11.0 ppm, after 10 minutes it is 10.2 ppm. Thus, a slight deodorizing effect can be obtained. Similarly, in the bamboo charcoal aqueous solution which is Control 3, it becomes 13.5 ppm after 2 minutes, 13.1 ppm after 4 minutes, 12.6 ppm after 6 minutes, 12.0 ppm after 8 minutes, 11.4 ppm after 10 minutes, A slight deodorizing effect can be obtained. This is due to the deodorizing effect of paper charcoal and bamboo charcoal. Further, the reason why the control 2 is superior in the deodorizing effect than the control 3 is that the paper charcoal 4 has a higher adsorption capacity than the bamboo charcoal. On the other hand, the initial concentration of 15 ppm is 2.7 ppm after 2 minutes, 1.2 ppm after 4 minutes, 1.0 ppm after 6 minutes, 1.0 ppm after 8 minutes, and 10 ppm after 10 minutes. It was confirmed that In Sample 2, it was confirmed that it became 7.5 ppm after 2 minutes, 5.0 ppm after 4 minutes, 4.5 ppm after 6 minutes, 3.5 ppm after 8 minutes, and 3.0 ppm after 10 minutes. . Thereby, it has confirmed that the functional substance of the scallop shell powder 2 also has a deodorizing effect. The reason why the sample 1 has a higher deodorizing effect than the sample 2 is that the paper charcoal 4 has a higher ability to adsorb organic substances in the scallop shell powder 2 than the bamboo charcoal.

酢酸の消臭効果試験結果に関しては［表９］及び［図８］に示すように、初期濃度５０ｐｐｍのものが対照１であるホタテ貝殻粉体２水溶液では２分後、４分後に４５ｐｐｍに、６分後、８分後に４６ｐｐｍに、１０分後に４７ｐｐｍに、１５分後に４６ｐｐｍに、２０分後に４７ｐｐｍに、２５分後、３０分後に４８ｐｐｍになることが確認できた。対照１で経過時間とともにガス濃度が上昇しているが、これはホタテ貝殻粉体２の有機物質により腐敗臭を出していることが原因である。また対照２であるペーパー炭４水溶液では２分後に４８ｐｐｍに、４分後に４７ｐｐｍに、６分後に４２ｐｐｍに、８分後に３８ｐｐｍに、１０分後に３６ｐｐｍに、１５分後に３５ｐｐｍに、２０分後に３１ｐｐｍに、２５分後に２６ｐｐｍに、３０分後に２４ｐｐｍになり、わずかながら消臭効果が得られる。同様に対照３である竹炭水溶液では２分後に４８ｐｐｍに、４分後に４８ｐｐｍに、６分後に４５ｐｐｍに、８分後に４２ｐｐｍに、１０分後に４０ｐｐｍに、１５分後に３９ｐｐｍに、２０分後に３６ｐｐｍに、２５分後に３２ｐｐｍに、３０分後に３０ｐｐｍになり、わずかながら消臭効果が得られる。これはペーパー炭及び竹炭が有する消臭効果によるものである。また、対照２の方が対照３より消臭効果が優れているのは、前述した如く、ペーパー炭４の方が竹炭より吸着能力が高いためである。これに対し、検体１では２分後に１０ｐｐｍに、４分後に７ｐｐｍに、６分後に５ｐｐｍに、８分後に３ｐｐｍに、１０分後には２ｐｐｍに、１５分後、２０分後に１ｐｐｍに、２５分後、３０分後に１ｐｐｍ以下となることが確認できた。また、検体２では２分後に２２ｐｐｍに、４分後に１５ｐｐｍに、６分後に１３ｐｐｍに、８分後に１０ｐｐｍ、１０分後には９ｐｐｍに、１５分後に７ｐｐｍに、２０分後に５ｐｐｍに、２５分後、３０分後に４ｐｐｍになることが確認できた。これにより、前述したように、ホタテ貝殻粉体２の機能物質にも消臭効果を有することが確認できた。また検体１の方が検体２より消臭効果が高いのは、ホタテ貝殻粉体２の有機物質の吸着能力が竹炭よりペーパー炭４の方が高いためである。 Regarding the deodorizing effect test result of acetic acid, as shown in [Table 9] and [FIG. 8], the scallop shell powder 2 aqueous solution whose initial concentration is 50 ppm is 45 ppm after 2 minutes and 4 minutes, After 6 minutes, 8 minutes, 46 ppm, 10 minutes 47 ppm, 15 minutes 46 ppm, 20 minutes 47 ppm, 25 minutes, 30 minutes 48 ppm. In the control 1, the gas concentration increases with the lapse of time, which is caused by the fact that the organic substance of the scallop shell powder 2 gives off a rotten odor. Also, in the paper charcoal 4 aqueous solution which is the control 2, it is 48 ppm after 2 minutes, 47 ppm after 4 minutes, 42 ppm after 6 minutes, 38 ppm after 8 minutes, 36 ppm after 10 minutes, 35 ppm after 15 minutes, and 31 ppm after 20 minutes. Furthermore, it becomes 26 ppm after 25 minutes and 24 ppm after 30 minutes, and a slight deodorizing effect is obtained. Similarly, the bamboo charcoal aqueous solution of Control 3 is 48 ppm after 2 minutes, 48 ppm after 4 minutes, 45 ppm after 6 minutes, 42 ppm after 8 minutes, 40 ppm after 10 minutes, 39 ppm after 15 minutes, and 36 ppm after 20 minutes. , 25 ppm after 25 minutes, 30 ppm after 30 minutes, a slight deodorizing effect is obtained. This is due to the deodorizing effect of paper charcoal and bamboo charcoal. In addition, the reason why the control 2 is superior to the control 3 in the deodorizing effect is because, as described above, the paper charcoal 4 has a higher adsorption capacity than the bamboo charcoal. On the other hand, Sample 1 was 10 ppm after 2 minutes, 7 ppm after 4 minutes, 5 ppm after 6 minutes, 3 ppm after 8 minutes, 2 ppm after 10 minutes, 15 minutes after 20 minutes, 1 ppm after 20 minutes, 25 minutes Thereafter, it was confirmed that the concentration became 1 ppm or less after 30 minutes. In Sample 2, 22 ppm after 2 minutes, 15 ppm after 4 minutes, 13 ppm after 6 minutes, 10 ppm after 8 minutes, 9 ppm after 10 minutes, 7 ppm after 15 minutes, 5 ppm after 20 minutes, and 25 minutes later After 30 minutes, it was confirmed to be 4 ppm. Thereby, as above-mentioned, it has confirmed that the functional substance of the scallop shell powder 2 also has a deodorizing effect. The reason why the sample 1 has a higher deodorizing effect than the sample 2 is that the paper charcoal 4 has a higher ability to adsorb organic substances in the scallop shell powder 2 than the bamboo charcoal.

消臭効果の確認として、イソ吉草酸及び酢酸から発生するガスを用いた理由は、イソ吉草酸から発生するガスは足の水虫の臭いに似ており、酢酸から発生するガスは脇毛からの汗の臭いに似ている等の理由によるものである。 The reason for using the gas generated from isovaleric acid and acetic acid to confirm the deodorizing effect is that the gas generated from isovaleric acid is similar to the smell of athlete's foot foot, and the gas generated from acetic acid is sweat from armpit hair. This is due to reasons such as being similar to
