第１図は、実施形態に係るステビア発酵液の製造方法の一例を示すフローチャートである。 FIG. 1 is a flowchart showing an example of a method for producing a stevia fermentation broth according to an embodiment.
以下、本発明の実施形態について説明する。
〔第１実施形態〕
第１実施形態に係るステビア発酵液の製造方法は、ステビアの茎部に対して活性水により４５〜６０℃で抽出を行い、得られたステビア抽出液を４５〜６０℃で濃縮した後、熟成（発酵）させるものである。この製造方法の一例を図１に示す。
ステビアとは、南米（パラグアイ）原産のキク科の植物〔学名：ステビア・レバウディアナ・ベルトーニ（Ｓｔｅｖｉａ ｒｅｂａｕｄｉａｎａ Ｂｅｒｔｏｎｉ）〕である。このようなステビアとしては、アワユキギク（Ｓ．ｏｖａｔａ）、ムラサキステビア（Ｓ．ｐｕｒｐｒｅａ）、イビフォリア（Ｓ．ｉｖｉｆｏｒｉａ）、サリシフォリア（Ｓ．ｓａｌｉｃｉｆｏｌｉａ）等が挙げられる。ステビアの茎部とは、ステビアの葉部や根部を除いた茎の部分をいう。
ステビア発酵液の製造に際しては、図１に示すように、まず、ステビアの茎部を多段式温風乾燥機等の乾燥機を用いて７０℃以下、好ましくは６０℃以下で数十時間乾燥（ステップＳ１）させた後、平均粒径１５μｍ以下の粉末に粉砕（ステップＳ２）するのが望ましい。乾燥を６０℃以下で行えば、ステビアの茎部に含まれているビタミンや酵母等がより分解又は死滅しにくいという利点がある。また、乾燥粉末の平均粒径を１５μｍ以下とすれば、抽出をより効率良く行うことができる。
次いで、得られた乾燥粉末を活性水に浸漬（ステップＳ３）し、真空濃縮装置等の加熱装置を用いて４５〜６０℃で数十分間〜数時間抽出（ステップＳ４）を行う。活性水（改質水）とは、活性化（改質）された水をいう。水の活性化法としては、電気分解、磁化処理、電子処理、超音波処理、鉱石・ミネラル処理等のうちの１種又は２種以上の併用が挙げられる。なお、鉱石・ミネラル処理とは、水を塊状、粒状、又は粉末状の鉱石と接触させて水にミネラル成分を添加する処理をいう。鉱石としては、トルマリン（電気石）、麦飯石（ベントナイト，石英・長石班石）、医王石（石川県の医王山の戸室地区で採取される天然鉱石，別名：戸室石，学名：石英閃緑玲石）、水晶、エメラルド、ルビー、サファイヤ、アメジスト等のうちの１種又は２種以上の混合物が挙げられる。乾燥粉末と活性水との重量比は特に限定されるものではないが、
活性水／乾燥粉末＝５〜７が適当である。
そして、数時間（例えば２時間）放冷（ステップＳ５）してからフィルタープレス等の固液分離装置（ろ過装置）を用いてろ過（ステップＳ６）し、ステビア抽出液をろ別する。抽出後の茎部の粉末は、上記の抽出処理に再使用してもよい。
その後、得られたステビア抽出液の濃縮（ステップＳ７）を、真空濃縮装置等を用いて４５〜６０℃で糖度が１０以上（１５〜２５が適当）又は酸化還元電位が−３０ｍＶ以下（−９０〜−３０ｍＶが適当）になるまで行う。濃縮（水の留去）に要する時間は、真空度や加熱温度等により適宜に決定される。
次いで、得られた濃縮液を熟成タンク内に投入し、常温で数カ月間（例えば６カ月間）熟成（ステップＳ８）させる。熟成後は、フィルタープレス等の固液分離装置を用いてろ過（ステップＳ９）し、ステビア発酵液をろ別するのが望ましい。
このような製造方法によれば、４５〜６０℃でステビア抽出液の抽出及び濃縮を行うので、ステビアの茎部に含まれているビタミンや酵母等が分解又は死滅するおそれがないという利点がある。また、活性水を用いるので、ステビア発酵液の熟成途中や熟成後における腐敗を防止できると共に、ステビアの茎部に含まれているビタミン、ミネラル成分、糖質、脂質、タンパク質、繊維質等の抽出を効率良く行うことができるという利点がある。
ここで、抽出をステビアの茎部と活性水との混合物に遠赤外線を照射しながら行えば、抽出をより効率良く行うことができるという利点がある。前記混合物に遠赤外線を照射するには、前記混合物が投入される加熱装置の加熱槽の外面等に遠赤外線放射セラミック（アルミナ等）の粉末を含む塗料を塗布等しておけばよい。
抽出を前記混合物に振動を与えながら行う場合も、上記と同様の利点がある。遠赤外線の照射と振動の付与とを併用すれば、より効果的である。前記混合物に振動を与えるには、前記加熱槽等にバイブレータ又は超音波発生器等を装備しておけばよい。
〔第２実施形態〕
第２実施形態に係る家畜用健康飲料は、第１実施形態の方法で製造されたステビア発酵液を含有するものである。
家畜としては、乳牛、搾乳牛、肉牛、豚、馬、山羊、羊、鶏等が挙げられる。家畜用健康飲料は、そのままの状態で家畜に飲ませたり、あるいは家畜の飼料や飲料水その他の飲料等に添加したりすることによって、家畜に給与することができる。
このような家畜用健康飲料によれば、既述のステビア発酵液を含有しているので、ステビア発酵液の甘味により家畜への嗜好性に富むと共に、家畜用***炎治療剤等の家畜用薬剤としての効能が高いという利点がある。これは、ステビア発酵液が家畜の健康増進に有用なビタミンや酵母等を含んでいるからであると考えられる。家畜用健康飲料の効能としては、家畜用***炎治療剤としての効能の他、家畜用の気管支炎治療剤、肺炎治療剤、肝臓機能減退症（肝炎）治療剤、卵巣機能減退症（空胎）治療剤、売買による移動又は環境変化によるストレス症治療剤等としての効能が挙げられる。
〔第３実施形態〕
第３実施形態に係る家畜用***洗浄剤は、第１実施形態の方法で製造されたステビア発酵液を含有するものである。
この家畜用***洗浄剤は、そのままの状態で又は活性水等により適度な濃度に希釈してから、家畜の***に塗布することができる。塗布方法としては、家畜の***（乳頭）に非接触で塗布可能なスプレー塗布等が好適である。
このような家畜用***洗浄剤によれば、既述のステビア発酵液を含有し、***炎の原因となる黄色ブドウ球菌等の細菌やウィルス等に対する抗菌効果に優れているので、家畜が***炎にかかりにくいという利点がある。これは、ステビア発酵液が抗菌効果に優れた物質を含んでいるからであると考えられる。
ここで、家畜用***洗浄剤がステビア発酵液に加えて二酸化チタン粉末も含有していれば、二酸化チタン粉末の光触媒作用により抗菌効果が更に高くなるという利点がある。なお、二酸化チタン粉末の重量率は数ｗｔ％でよいが、その平均粒径は１００ｎｍ以下であることが望ましい。二酸化チタン粉末の平均粒径が１００ｎｍ以下であれば、光触媒作用に優れるので、これを含有する家畜用***洗浄剤の抗菌効果もより高くなるという利点がある。
また、家畜用***洗浄剤がステビア発酵液に加えて３，６−Ｏ−ジメチルキチン（水溶性，水溶液は中性）も含有していれば、家畜の皮膚になじみ易く（家畜の皮膚に対する親和性が高く）、ゲル状（クリーム状）の形態で家畜の***に塗布できるので、抗菌効果の持続時間を長くできると共に、乳口にすり込むように塗布することもできるという利点がある。なお、３，６−Ｏ−ジメチルキチンの重量率は数ｗｔ％でよい。また、二酸化チタン粉末と３，６−Ｏ−ジメチルキチンとを併用すれば、より効果的である。
３，６−Ｏ−ジメチルキチンは、日本国・特許第３１７７６１３号公報に記載の方法（▲１▼キチンをアルカリ処理して調製したアルカリキチン水溶液にメチル化剤を加えて撹拌、反応させることを特徴とする３，６−Ｏ−ジメチルキチンの製造方法。好ましくは、▲２▼前記メチル化剤を加える前に前記アルカリキチン水溶液を５０℃以下で熟成させて脱アセチル化率が４０〜６０％となるように部分脱アセチル化することを特徴とする３，６−Ｏ−ジメチルキチンの製造方法。）で製造するのが好適である。上記▲１▼の方法を用いた場合は、３，６−Ｏ−ジメチルキチンの製造が容易であると共に、高分子量の３，６−Ｏ−ジメチルキチンも得られるという利点がある。また、上記▲２▼の方法を用いた場合は、アルカリキチン水溶液に不溶分が残らず、そのため、ろ過等の手間を省くことができるという利点がある。Hereinafter, embodiments of the present invention will be described.
[First Embodiment]
The manufacturing method of the stevia fermented liquid which concerns on 1st Embodiment extracts after aging at 45-60 degreeC with the active water with respect to the stalk part of stevia, and concentrates the obtained stevia extract at 45-60 degreeC, Then, it matures (Fermented). An example of this manufacturing method is shown in FIG.
Stevia is an Asteraceae plant (scientific name: Stevia rebaudiana Bertoni) native to South America (Paraguay). Examples of such stevia include Awayukikiku (S. ovata), Murasakikistevia (S. purprea), Ibifolia (S. ibifolia), Salicifolia (S. salicifolia) and the like. Stevia stem refers to the portion of the stem excluding Stevia leaves and roots.
In producing the stevia fermentation broth, as shown in FIG. 1, first, the stem portion of stevia is dried at 70 ° C. or lower, preferably 60 ° C. or lower for several tens of hours using a dryer such as a multi-stage hot air dryer ( After step S1), it is desirable to grind (step S2) into a powder having an average particle size of 15 μm or less. If drying is performed at 60 ° C. or less, there is an advantage that vitamins and yeasts contained in the stem portion of stevia are more difficult to decompose or die. If the average particle size of the dry powder is 15 μm or less, extraction can be performed more efficiently.
Next, the obtained dry powder is immersed in active water (step S3), and extraction (step S4) is performed for several tens of minutes to several hours at 45 to 60 ° C. using a heating device such as a vacuum concentrator. Active water (reformed water) refers to activated (reformed) water. Examples of the water activation method include one or more of electrolysis, magnetization treatment, electronic treatment, ultrasonic treatment, ore / mineral treatment, and the like. The ore / mineral treatment refers to a treatment in which water is brought into contact with a massive, granular, or powdered ore to add a mineral component to the water. The ores include tourmaline (electric stone), barley stone (bentonite, quartz, feldspar), Ioishi (natural ore collected in the Tomuro area of Ioyama, Ishikawa Prefecture, aka Tomuro stone, scientific name: quartz diorite. 1) or a mixture of two or more of quartz, emerald, ruby, sapphire, amethyst and the like. The weight ratio of dry powder and active water is not particularly limited,
Active water / dry powder = 5-7 is suitable.
And after standing to cool for several hours (for example, 2 hours) (step S5), it filters (step S6) using solid-liquid separators (filter apparatus), such as a filter press, and separates a stevia extract. You may reuse the powder of the stem part after extraction for said extraction process.
Thereafter, the obtained stevia extract is concentrated (step S7) by using a vacuum concentrator or the like at 45-60 ° C. with a sugar content of 10 or more (15-25 is suitable) or an oxidation-reduction potential of −30 mV or less (−90 ˜-30 mV is suitable). The time required for concentration (water distillation) is appropriately determined depending on the degree of vacuum, heating temperature, and the like.
Next, the obtained concentrated liquid is put into an aging tank and aged for several months (for example, 6 months) at room temperature (step S8). After aging, it is desirable to filter (step S9) using a solid-liquid separator such as a filter press to separate the stevia fermentation broth.
According to such a manufacturing method, the extraction and concentration of the stevia extract is performed at 45 to 60 ° C., and thus there is an advantage that vitamins and yeasts contained in the stem portion of stevia are not decomposed or killed. . In addition, since active water is used, it is possible to prevent rot during and after maturation of Stevia fermented liquid, and extraction of vitamins, mineral components, carbohydrates, lipids, proteins, fibers, etc. contained in Stevia stems There is an advantage that can be performed efficiently.
Here, if extraction is performed while irradiating a mixture of stevia stem and active water with far infrared rays, there is an advantage that extraction can be performed more efficiently. In order to irradiate the mixture with far-infrared rays, a paint containing a far-infrared radiation ceramic (alumina or the like) powder may be applied to the outer surface of a heating tank of a heating apparatus into which the mixture is charged.
There is an advantage similar to the above also when the extraction is performed while applying vibration to the mixture. It is more effective if the irradiation with far infrared rays and the application of vibration are used in combination. In order to give vibration to the mixture, the heating tank or the like may be equipped with a vibrator or an ultrasonic generator.
[Second Embodiment]
The health drink for livestock which concerns on 2nd Embodiment contains the stevia fermented liquid manufactured by the method of 1st Embodiment.
Examples of livestock include dairy cows, milked cows, beef cattle, pigs, horses, goats, sheep, and chickens. Livestock health drinks can be fed to livestock by feeding them as they are, or by adding them to livestock feed, drinking water or other beverages.
According to such a health drink for livestock, since it contains the above-mentioned stevia fermented liquid, the sweetness of the stevia fermented liquid has high palatability for livestock, and a livestock medicine such as a mastitis therapeutic agent for livestock. It has the advantage of high efficacy. This is thought to be because the stevia fermented liquid contains vitamins and yeasts that are useful for improving the health of livestock. In addition to its efficacy as a mastitis treatment agent for livestock, the health drinks for domestic animals include bronchitis treatment agents, pneumonia treatment agents, liver dysfunction (hepatitis) treatment agents, ovarian dysfunction (emptiness) ) Efficacy as a therapeutic agent, an agent for the treatment of stress due to movement by trade or environmental change.
[Third Embodiment]
The livestock breast cleaning agent according to the third embodiment contains a stevia fermented liquid produced by the method of the first embodiment.
The livestock breast cleaning agent can be applied to livestock breasts as they are or after being diluted to an appropriate concentration with active water or the like. As an application method, spray application that can be applied in a non-contact manner to the breast (nipple) of livestock is suitable.
According to such a breast cleaning agent for livestock, since it contains the aforementioned stevia fermented liquid and has an excellent antibacterial effect against bacteria and viruses such as Staphylococcus aureus that cause mastitis, There is an advantage that it is difficult to start. This is thought to be because the stevia fermented liquid contains a substance having an excellent antibacterial effect.
Here, if the breast cleaning agent for livestock contains titanium dioxide powder in addition to the stevia fermented liquid, there is an advantage that the antibacterial effect is further enhanced by the photocatalytic action of the titanium dioxide powder. The weight ratio of the titanium dioxide powder may be several wt%, but the average particle size is desirably 100 nm or less. If the average particle diameter of the titanium dioxide powder is 100 nm or less, the photocatalytic action is excellent, so that there is an advantage that the antibacterial effect of the livestock breast cleaning agent containing the titanium dioxide powder becomes higher.
In addition, if the breast cleaning agent for livestock also contains 3,6-O-dimethylchitin (water-soluble, aqueous solution is neutral) in addition to the stevia fermented liquid, it is easy to adjust to livestock skin (affinity to livestock skin) Since it can be applied to the breasts of livestock in the form of a gel (cream), the antibacterial effect can be prolonged and it can be applied so as to be rubbed into the nipple. The weight percentage of 3,6-O-dimethylchitin may be several wt%. Moreover, it is more effective if titanium dioxide powder and 3,6-O-dimethylchitin are used in combination.
3,6-O-dimethylchitin is a method described in Japanese Patent No. 3177613 (1) A methylating agent is added to an aqueous alkaline chitin solution prepared by alkali treatment of chitin and stirred and reacted. A method for producing 3,6-O-dimethylchitin, which is characterized in that, preferably, (2) the alkali chitin aqueous solution is aged at 50 ° C. or lower before the methylating agent is added, and the deacetylation rate is 40 to 60%. It is preferable to produce it by a method for producing 3,6-O-dimethylchitin, characterized by partial deacetylation so that When the method (1) is used, there is an advantage that 3,6-O-dimethylchitin can be easily produced and high molecular weight 3,6-O-dimethylchitin can be obtained.
