【発明の属する技術分野】
本発明は、水が加えられると粘性又はゲル化が発現するゲル素材溶液、並びにそれが含まれた食品、医薬品、医薬部外品、医療用品、化粧品、衛生用品、日用品、飼料、魚餌、ペットフード、肥料、栄養剤及び農薬に関する。
【０００２】
【従来の技術】
寒天などの水溶性ゲル素材は、熱可逆性のハイドロコロイドで、熱水に溶解させて流動性を有する水溶液とすることができるが、冷却すると凝固してゲルを形成する。このようにゲルを形成した水溶性ゲル素材は、様々な食材や機能性ゲルなどに利用されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、水溶性ゲル素材の凝固温度、すなわちゲル化する温度は、素材の種類かその使用濃度により異なるが、例えば通常使用される０．５〜１．０％の寒天の凝固温度は、概ね３０〜４０℃である。したがって、寒天は、常温でゲル化してしまい、流動性がある液体として扱うためには高温で保存する必要がある。また、一旦ゲル化してしまうと、再溶解するためには、８０℃以上に加熱する必要があり、扱いにくいという問題がある。
【０００４】
そこで、本発明は、常温であってもゾル状態を保つことができるゲル素材溶液、並びにそれが含まれた食品、医薬品、医薬部外品、医療用品、化粧品、衛生用品、日用品、飼料、魚餌、ペットフード、肥料、栄養剤及び農薬を提供することを目的とする。
【０００５】
【課題を解決するための手段】
以上の目的を達成するため、本発明者らは、鋭意検討を重ねた結果、非水系溶媒に熱可逆性の水溶性ゲル素材を溶解させると、その水溶性ゲル素材の水溶液がゲル化する温度であってもゾル状態を保つことができ、それに水を加えると粘性又はゲル化が発現することを見出した。
【０００６】
すなわち、本発明は、熱可逆性の水溶性ゲル素材が非水系溶媒に溶解された溶液であって、少なくとも前記ゲル素材の水溶液がゲル化する温度でゾル状態を保ち、水が加えられると粘性又はゲル化が発現することを特徴とするゲル素材溶液である。
【０００７】
【発明の実施の形態】
本発明に係るゲル素材溶液は、水が加えられると、前記水溶性ゲル素材が溶解している非水系溶媒と加えられた水が置き換わって、粘性又はゲル化が発現するものと考えられる。
【０００８】
本発明に係るゲル素材溶液は、水を加えた後に、攪拌や振動を加えることにより、粘性又はゲル化の発現を早めることができる。
【０００９】
本発明に係るゲル素材溶液において、ゾル状態とは、水溶性ゲル素材の分子間の結合が不十分である状態であり、粘性又はゲル化が発現するとは、水の添加により分子間の水素結合が強まり会合度合が強くなる状態をいう。
【００１０】
本発明に係るゲル素材溶液において、前記水溶性ゲル素材の含有量が、０．０２〜１０％であることが好ましく、０．０２％より少ないと、水を加えても粘性又はゲル化が発現せず、また１０％より多いと溶解してもゾル状態を保つことができない。
【００１１】
また、本発明に係るゲル素材溶液において、前記水溶性ゲル素材は、寒天、アガロース、カラギナン、ファーセレラン、ゼラチン、ジェランガム（脱アシル型、ネーティブ型）及びデンプンのうちいずれか一以上であることが好ましく、前記非水系溶媒は、グリセリン、エチレングリコール、ジエタノールアミン、トリエタノールアミン、ジメチルスルフオキサイド、ホルムアミド、エタノールアミンのうちいずれか一以上であることが好ましい。特に、前記水溶性ゲル素材として寒天を用いた場合、その寒天のアガロペクチン含有量が５０重量％以下であることが好ましい。
【００１２】
本発明に係るゲル素材溶液は、水を加えることにより容易に粘性又はゲル化を発現するので、様々な食品、ペットフード、魚餌、畜産・水産飼料として利用することができる。例えば、本発明に係るゲル素材溶液を細い管から水が入った容器に押出すことにより麺状のゲル状食品を得ることができ、また水を重層することにより水が拡散して二層ゲルとなる。
【００１３】
また、本発明に係るゲル素材溶液は、前記非水系溶媒が軟化剤として含まれている食品において、軟化剤に前記水溶性ゲルを加えて溶解させることによって、食品の物性を改良する目的として利用しても良い。例えば食品の軟化剤として利用されるグリセリンに前記水溶性ゲル素材を溶かして食品に混練することにより、新しい食感の食品を得ることができる。具体的には、チューインガムに混練させた場合、口腔内で咀嚼により唾液とグリセリンが置換しゼリー化又は増粘化して咀嚼強度を変化させることができ、咀嚼機能を強化することができる。さらに、このように前記ゲル素材溶液を含ませているチューインガムは、噛んだ後に排出される際の付着性を低減させる効果を有する。マナーの悪さから噛んだ後のチューインガムが吐き捨てられて、道路等にくっつくことが環境上問題にされているが、このように前記ゲル素材溶液を含ませることにより、吐き捨てられたチューインガムを道路等から容易に剥がすことができる。
【００１４】
また、本発明に係るゲル素材溶液は、魚餌に練り込ませて練り餌として利用しても良い。すなわち、魚の養殖において練り餌を水中に投げ込むが、このとき、練り餌が簡単に吸水して崩壊し水中に散ってしまうと、魚餌効率が悪くなるばかりか、水を汚染してしまうため、環境上好ましくない。非水系溶媒に水溶性ゲル素材が溶解された本発明に係るゲル素材溶液を魚餌に練り込むことにより、吸水して粘性又はゲル化が発現し、壊れ難くなるため、本発明に係るゲル素材溶液は、魚餌に含ませることにより、有用な効果を奏することができる。
【００１５】
また、本発明に係るゲル素材溶液は、化粧品、医薬品、医薬部外品、医療用品又は衛生用品などに利用することができる。化粧品としては、基礎化粧品、メーキャップ化粧品、ボディ化粧品、頭髪用化粧品、頭皮用化粧品、口腔用化粧品、芳香化粧品に利用でき、例えば、パック、化粧クリーム、ヘアカラー、シャンプー、除毛クリームなどに利用することができる。また、医薬品、医薬部外品及び医療用品としては、外皮用薬、歯科口腔用剤、アレルギー用薬、呼吸器官用薬、腫瘍用薬、公衆衛生用薬、体外診断用医薬、診断用薬に利用することができ、例えば、止血剤、シーラント、ハップ剤、ＤＤＳ基剤、口内炎薬、鼻炎薬又は人工皮膚などに利用することができる。衛生用品としては、おむつ、生理用品などに利用することができる。具体的には、ハップ剤の有効成分を含ませることにより、液体のハップ剤として利用することができる。すなわち、ハップ剤の有効成分を含ませたゲル素材溶液を患部に塗布し、その上に水に濡らしたタオルなどを置くことにより、ゲル化して患部から流れ落ちるのを防止できる。また、口内炎薬や鼻炎薬を含ませることにより、液体状の口内炎薬や鼻炎薬などとして利用することができる。すなわち、口内炎薬などを含ませたゲル素材溶液を口内炎の患部などに塗布すると唾液などによりゲル化するので、通常唾液などで流れてしまう口内炎薬を患部に長時間保持させることができる。
【００１６】
さらに、本発明に係るゲル素材溶液は、農業・園芸材料、水産材料などに利用することができる。例えば、葉面散布剤、農薬、肥料などである。具体的には、植物などの栄養成分又は農薬などを含ませることにより、植物の栄養剤などとして利用することができる。すなわち、植物の栄養成分などを含ませたゲル素材溶液を植物の土に散布してその上に水を散布することにより、ゲル化させることができるので、通常水を散布すると流れてしまう栄養成分などを長時間保持することができる。
【００１７】
その他に本発明に係るゲル素材溶液は、電池、センサー若しくはケーブルなどの電子・電気工業用品、写真フィルム、電気泳動、塗料若しくは印刷インキなどの化学工業用品、シール材、汚泥処理材若しくはシールド材などの建築・土木材料、芳香剤、消臭材、ペット用処理剤、吸水シート、保冷材、水分保持材、歯磨き粉、洗剤、入浴剤、洗髪剤若しくはワックスなどの日用品や包装材料、又は人工雪若しくは釣用品などのスポーツ・レジャー用品などに利用することができる。

It relates to foods, fertilizers, nutrients and pesticides.
[0002]
[Prior art]
A water-soluble gel material such as agar is a thermoreversible hydrocolloid, which can be dissolved in hot water to give a fluid aqueous solution, but solidifies upon cooling to form a gel. The water-soluble gel material in which the gel is thus formed is used for various foods and functional gels.
[0003]
[Problems to be solved by the invention]
However, the solidification temperature of the water-soluble gel material, that is, the gelation temperature varies depending on the type of material or the concentration of the material used. For example, the solidification temperature of 0.5 to 1.0% of agar usually used is about 30. ~ 40 ° C. Therefore, agar gels at room temperature and needs to be stored at a high temperature in order to handle it as a fluid liquid. Further, once gelled, in order to re-dissolve, it is necessary to heat to 80 ° C. or higher, which is difficult to handle.
[0004]
Therefore, the present invention provides a gel material solution that can maintain a sol state even at room temperature, and foods, pharmaceuticals, quasi drugs, medical products, cosmetics, hygiene products, daily necessities, feed, fish food containing the same. It aims to provide pet food, fertilizer, nutrients and pesticides.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present inventors have conducted extensive studies, and as a result, when a thermoreversible water-soluble gel material is dissolved in a non-aqueous solvent, the temperature at which the aqueous solution of the water-soluble gel material gels. Even so, it was found that the sol state could be maintained, and that viscosity or gelation was developed when water was added thereto.
[0006]
That is, the present invention is a solution in which a thermoreversible water-soluble gel material is dissolved in a non-aqueous solvent, and maintains a sol state at least at a temperature at which the aqueous solution of the gel material gels. Alternatively, the gel material solution is characterized in that gelation occurs.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
In the gel material solution according to the present invention, when water is added, the non-aqueous solvent in which the water-soluble gel material is dissolved is replaced with the added water, and viscosity or gelation appears.
[0008]
The gel material solution according to the present invention can accelerate the onset of viscosity or gelation by adding stirring and vibration after adding water.
[0009]
In the gel material solution according to the present invention, the sol state is a state in which bonding between molecules of the water-soluble gel material is insufficient, and the expression of viscosity or gelation means that hydrogen bonding between molecules is caused by the addition of water. Means that the degree of meeting increases and the degree of meeting increases.
[0010]
In the gel material solution according to the present invention, the content of the water-soluble gel material is preferably 0.02 to 10%. When the content is less than 0.02%, viscosity or gelation is exhibited even when water is added. In addition, if it exceeds 10%, the sol state cannot be maintained even when dissolved.
[0011]
In the gel material solution according to the present invention, the water-soluble gel material is preferably one or more of agar, agarose, carrageenan, far celerane, gelatin, gellan gum (deacylated type, native type) and starch. The non-aqueous solvent is preferably at least one of glycerin, ethylene glycol, diethanolamine, triethanolamine, dimethylsulfoxide, formamide, and ethanolamine. In particular, when agar is used as the water-soluble gel material, the agar pectin content of the agar is preferably 50% by weight or less.
[0012]
Since the gel material solution according to the present invention easily develops viscosity or gelation by adding water, it can be used as various foods, pet food, fish food, livestock / fishery feed. For example, it is possible to obtain a noodle-like gel food by extruding the gel raw material solution according to the present invention from a thin tube into a container containing water, and water is diffused by layering water to form a two-layer gel. It becomes.
[0013]
Further, the gel material solution according to the present invention is used for the purpose of improving the physical properties of food by adding the water-soluble gel to the softener and dissolving it in the food containing the non-aqueous solvent as a softener. You may do it. For example, a food having a new texture can be obtained by dissolving the water-soluble gel material in glycerin used as a food softening agent and kneading the food. Specifically, when kneaded into chewing gum, saliva and glycerin are replaced by chewing in the oral cavity to change the chewing strength by jelly or thickening, and the chewing function can be enhanced. Further, the chewing gum containing the gel material solution in this way has an effect of reducing adhesion when discharged after chewing. It is an environmental problem that chewing gum after chewing due to bad manners sticks out and sticks to the road etc., but by including the gel material solution in this way, It can be easily peeled off.
[0014]
Further, the gel material solution according to the present invention may be kneaded into a fish food and used as a kneaded food. In other words, throwing paste feed into the water during fish farming, but if the paste feed easily absorbs water and collapses and scatters in the water, not only will the fish feed efficiency deteriorate, but it will also contaminate the water. Not preferable. Since the gel material solution according to the present invention in which the water-soluble gel material is dissolved in the non-aqueous solvent is kneaded into the fish food, it absorbs water and develops viscosity or gelation and is difficult to break. Can have a useful effect by being included in the fish food.
[0015]
The gel material solution according to the present invention can be used for cosmetics, pharmaceuticals, quasi drugs, medical supplies, hygiene supplies, and the like. Cosmetics can be used for basic cosmetics, makeup cosmetics, body cosmetics, hair cosmetics, scalp cosmetics, oral cosmetics, aromatic cosmetics, for example, packs, cosmetic creams, hair colors, shampoos, hair removal creams, etc. be able to. In addition, pharmaceuticals, quasi-drugs and medical supplies include skin drugs, dental and oral drugs, allergy drugs, respiratory organ drugs, tumor drugs, public health drugs, in-vitro diagnostic drugs, and diagnostic drugs. For example, it can be used for a hemostatic agent, sealant, haptic agent, DDS base, stomatitis drug, rhinitis drug, artificial skin, and the like. As a sanitary product, it can be used for diapers, sanitary products and the like. Specifically, it can be used as a liquid haptic agent by including an active ingredient of the haptic agent. That is, by applying a gel material solution containing an active ingredient of a haptic agent to the affected area and placing a towel wetted with water on the affected area, it is possible to prevent gelation and flow from the affected area. Moreover, by including a stomatitis medicine or a rhinitis medicine, it can be used as a liquid stomatitis medicine or a rhinitis medicine. That is, when a gel material solution containing a stomatitis drug or the like is applied to an affected area of stomatitis or the like, it is gelled by saliva or the like, so that the stomatitis drug that normally flows in saliva or the like can be retained in the affected area for a long time.
[0016]
