　カードランは粉末で使用した場合でも効果を発揮するが、水に不溶性の物質であるため、加工食品の製造等においてカードランの機能を十分に発揮し得ていないという問題がある。 Although curdlan is effective even when used in powder form, it is a substance that is insoluble in water, so there is a problem that curdlan functions cannot be fully demonstrated in the manufacture of processed foods.
　カードランは酸性から中性付近では水には不溶であることから、カードラン単体を水に添加するとカードランの沈殿が生じる場合がある。カードランはアルカリ性水溶液には可溶である性質から、その水溶液を調製するためには、事前にカードランを水に分散させた分散液とアルカリ性の溶液を別々に用意し、撹拌機等での機械混合等が必要であった。 Since curdlan is insoluble in water from acidity to neutrality, when curdlan alone is added to water, curdlan may precipitate. Since curdlan is soluble in alkaline aqueous solution, in order to prepare the aqueous solution, a dispersion in which curdlan is dispersed in water in advance and an alkaline solution are prepared separately. Mechanical mixing was necessary.
　このようにカードランはアルカリ状態では水に可溶となるが、アルカリ溶液に直接カードランを添加すると凝集物（いわゆる「だま」）を形成することや、カードラン分散液とアルカリ溶液の２液を準備してカードラン溶液の作製手間が必要なこと等のため、カードラン水溶液の製造工程が煩雑となる（特許文献１参照）。このようなカードラン水溶液の調製の手間を省くため、カードランにアルカリ剤を事前に粉体配合した混合物を調製し、これを水に加えて混合して、カードラン分散液を得る方法が考えられるが、混合溶液のｐＨを指標として調製された混合物を水に添加した場合、凝集物が生じて均一な分散溶液をつくることが困難である。 Thus, curdlan is soluble in water in an alkaline state, but when curdlan is added directly to an alkaline solution, an aggregate (so-called “dama”) is formed, or two solutions of curdlan dispersion and alkaline solution are formed. The manufacturing process of the curdlan aqueous solution becomes complicated (see Patent Document 1). In order to save the trouble of preparing such a curdlan aqueous solution, a method of preparing a curdlan dispersion by preparing a mixture of a curdlan and an alkaline agent previously mixed with powder and adding it to water is mixed. However, when a mixture prepared using the pH of the mixed solution as an indicator is added to water, it is difficult to produce an aggregate and produce a uniform dispersion solution.
　この問題を解決したカードラン混合物として、被覆されたアルカリ剤を使用したカードラン混合物が知られている（特許文献２参照）。この混合物を水に添加すると、カードランが水になじみ、続いて被覆されたアルカリ剤からアルカリが溶出されるので、凝集物が形成されにくくなる。しかし、特許文献２のようなカードラン製剤の調製には被覆されたアルカリ剤を用意する必要がある。また、カードランが水に不溶な素材であることからカードランがすぐに沈殿し、容易にカードラン分散液を作製することは困難である。 A curdlan mixture using a coated alkaline agent is known as a curdlan mixture that solves this problem (see Patent Document 2). When this mixture is added to water, the curdlan becomes familiar with the water, and then the alkali is eluted from the coated alkaline agent, so that aggregates are hardly formed. However, it is necessary to prepare a coated alkaline agent for the preparation of a curdlan preparation as in Patent Document 2. Further, since the curdlan is a material insoluble in water, the curdlan immediately precipitates, and it is difficult to easily produce a curdlan dispersion.
　このため、水に分散させた際に凝集物が生じにくく、かつカードラン分散液を容易に調製することができるカードラン含有組成物の開発が望まれている。 For this reason, it is desired to develop a curdlan-containing composition that is less likely to generate aggregates when dispersed in water and that can easily prepare a curdlan dispersion.

　本発明の実施の形態について以下説明する。本実施形態は本発明を実施する一例であって、本発明は本実施形態に限定されるものではない。 Embodiments of the present invention will be described below. This embodiment is an example for carrying out the present invention, and the present invention is not limited to this embodiment.
　本発明の実施の形態に係るカードラン含有組成物は、カードランおよびアルカリ塩を含有し、カードランおよびアルカリ塩が顆粒化されている。ここで、カードランおよびアルカリ塩が「顆粒化」されているとは、カードランおよびアルカリ塩が同一粒子内に含まれており、後述する粒子の体積平均粒径が９０μｍ以上、好ましくは１３０μｍ以上であることを指す。本実施形態に係るカードラン含有組成物は、カードランおよびアルカリ塩を混合して粒状に造粒したものである。 The curdlan-containing composition according to the embodiment of the present invention contains curdlan and an alkali salt, and the curdlan and the alkali salt are granulated. Here, the curdlan and the alkali salt are “granulated” means that the curdlan and the alkali salt are contained in the same particle, and the volume average particle diameter of the particle described later is 90 μm or more, preferably 130 μm or more. It means that. The curdlan-containing composition according to this embodiment is obtained by mixing curdlan and an alkali salt and granulating them into granules.
　カードランおよびアルカリ塩が顆粒化されていることにより、水に分散または溶解させた際に凝集物を生じにくく、かつカードラン分散液または溶解液を容易に調製することができる。本実施形態に係るカードラン含有組成物により、カードランの加熱凝固性や保水性等を維持しつつ、低濃度から高濃度のカードランを従来法よりも短時間で水へ容易に分散または溶解させることが可能となる。また、カードランおよびアルカリ塩が顆粒化されていることにより、ハンドリング性が向上する。カードランにアルカリ塩を配合し、さらに顆粒化されていることによって粒子の膨潤性が向上するため、このカードラン含有組成物を含有させた食品等の製品に対する品質改良効果が向上する。 The granulation of curdlan and alkali salt makes it difficult to produce aggregates when dispersed or dissolved in water, and a curdlan dispersion or solution can be easily prepared. With the curdlan-containing composition according to the present embodiment, a curdlan having a low concentration to a high concentration can be easily dispersed or dissolved in water in a shorter time than the conventional method while maintaining the heat solidification property and water retention of the curdlan. It becomes possible to make it. Moreover, handling property improves by curdlan and alkali salt being granulated. When the curdlan is blended with an alkali salt and further granulated, the swellability of the particles is improved. Therefore, the quality improvement effect for products such as foods containing the curdlan-containing composition is improved.
　本発明の実施の形態に係るカードラン含有組成物によれば、事前に水に不溶なカードランを分散させるために増粘多糖類等の粘度を付与する物質との併用や、事前にカードランを水に分散させた分散液とアルカリ性の溶液を別々に用意しなくてもよく、一度に低濃度から高濃度まで水に分散または溶解させることができ、カードラン分散液または水溶液の製造工程が簡略化される。また、被覆されたアルカリ剤を用意しなくてもよい。 According to the curdlan-containing composition according to the embodiment of the present invention, the curdlan is used in combination with a substance that imparts viscosity such as a thickening polysaccharide in order to disperse the curdlan insoluble in advance. It is not necessary to prepare a dispersion in which water is dispersed in water and an alkaline solution separately, and it can be dispersed or dissolved in water from a low concentration to a high concentration at one time. Simplified. Further, it is not necessary to prepare a coated alkaline agent.
　また、カードランは加熱凝固性の素材であることから、従来法では５０℃前後の温水中にカードランを添加すると特に高濃度状態で略均質な溶液作製が困難であったが、本実施形態に係るカードラン含有組成物によれば、５０℃前後の温水へ添加しても分散液の作製が可能となる。 In addition, since curdlan is a heat-coagulable material, it is difficult to produce a substantially homogeneous solution in a high concentration state by adding curdlan to hot water around 50 ° C. in the conventional method. According to the curdlan-containing composition according to, a dispersion can be prepared even when added to warm water around 50 ° C.
　以下、本実施形態に係るカードラン含有組成物について、食品や飲料用途等を基準とし説明を行うが、その他、医薬品、工業用、医薬部外品、化粧品、飼料用途等、食品関連以外の用途も含むものとする。 Hereinafter, the curdlan-containing composition according to the present embodiment will be described with reference to food and beverage applications, etc., but also other uses such as pharmaceuticals, industrial use, quasi-drugs, cosmetics, feed use, etc. Shall also be included.
　本実施形態で用いられるカードランは、微生物によって生産されるβ－１，３－グルコシド結合を主体とする加熱凝固性多糖類である。この多糖類としては、アルカリゲネス属またはアグロバクテリウム属の微生物によって生産されるもの等が挙げられる。具体的には、カードランは、アルカリゲネス・フェカリス・バールミクソゲネス（Ａｌｃａｌｉｇｅｎｅｓ　ｆａｅｃａｌｉｓ　ｖａｒ．ｍｙｘｏｇｅｎｅｓ）菌株１０Ｃ３Ｋ［アグリカルチュラル・バイオロジカル・ケミストリー，Ｖｏｌ．３０，ｐ１９６（１９６６）］、アルカリゲネス・フェカリス・バールミクソゲネス（Ａｌｃａｌｉｇｅｎｅｓ　ｆａｅｃａｌｉｓ　ｖａｒ．ｍｙｘｏｇｅｎｅｓ）菌株１０Ｃ３Ｋの変異株ＮＴＫ－ｕ（ＩＦＯ１３１４０）、アグロバクテリウム・ラジオバクター（ＩＦＯ１３１２７）およびその変異株Ｕ－１９（ＩＦＯ１３１２６）により生産される多糖類である。カードランは、市販のものを使用してもよい。 The curdlan used in the present embodiment is a heat-coagulable polysaccharide mainly composed of β-1,3-glucoside bonds produced by microorganisms. Examples of the polysaccharide include those produced by microorganisms of the genus Alkagenes or Agrobacterium. Specifically, curdlan is obtained from Alcaligenes faecalis var. Myxogenes strain 10C3K [Agricultural Biological Chemistry, Vol. 30, p196 (1966)], Alkaligenes faecalis var. Myxogenes strain 10C3K mutant NTK-u (IFO13140), Agrobacterium radiobacter (IFO13127) and its mutant U-19 It is a polysaccharide produced by (IFO13126). A commercially available card run may be used.
　本実施形態で用いられるアルカリ塩としては、無機塩基、例えば、アルカリ金属水酸化物（例えば、水酸化ナトリウム等）、アルカリ金属炭酸塩（例えば、炭酸ナトリウム等）、アルカリ金属重炭酸塩（例えば、炭酸水素ナトリウム等）、リン酸等の無機酸のアルカリ金属塩（例えば、リン酸三ナトリウム、リン酸三カリウム等）等のアルカリ金属の無機塩等が挙げられる。アルカリ塩としては、好ましくは、アルカリ金属の無機塩であり、より好ましくは、リン酸のアルカリ金属塩およびアルカリ金属水酸化物であり、水に分散または溶解させた際に凝集物を生じにくい等の点から、特に好ましくは、リン酸三ナトリウム、リン酸三カリウム、および水酸化ナトリウムである。アルカリ塩は、１種単独で用いてもよいし、２種以上を併用してもよい。アルカリ塩は、特に被覆等の処理が施されたものでなくてもよい。 Examples of the alkali salt used in the present embodiment include an inorganic base such as an alkali metal hydroxide (for example, sodium hydroxide), an alkali metal carbonate (for example, sodium carbonate), an alkali metal bicarbonate (for example, Sodium hydrogen carbonate and the like, and alkali metal inorganic salts such as phosphoric acid (for example, trisodium phosphate, tripotassium phosphate, etc.) and the like. The alkali salt is preferably an inorganic salt of an alkali metal, more preferably an alkali metal salt or an alkali metal hydroxide of phosphoric acid, which hardly generates an aggregate when dispersed or dissolved in water. From these points, trisodium phosphate, tripotassium phosphate, and sodium hydroxide are particularly preferable. An alkali salt may be used individually by 1 type, and may use 2 or more types together. The alkali salt may not be subjected to a treatment such as coating.
　本実施形態に係るカードラン含有組成物中のアルカリ塩の含有量は、カードラン含有組成物を水に分散または溶解させて得られる分散液または水溶液のｐＨ、例えば、カードラン含有組成物をカードラン含有量として水に２重量％分散または溶解させて得られる分散液または水溶液のｐＨを１０以上、好ましくは、１１以上、例えば１０～１３の範囲、さらに好ましくは１１～１３の範囲にする量であればよい。得られる分散液または水溶液のｐＨが１０未満では、液が粘調液とはならない場合があり、１３を超えると、アルカリが強すぎることにより十分な粘性発現が起こらない場合がある。なお、カードラン含有組成物をカードラン含有量として水に２重量％加えた際、ｐＨが１１未満では、カードランは水に分散し、ｐＨが１１以上になると、カードランは水に分散または溶解する。 The content of the alkali salt in the curdlan-containing composition according to this embodiment is the pH of a dispersion or an aqueous solution obtained by dispersing or dissolving the curdlan-containing composition in water, for example, the curdlan-containing composition. The amount of the dispersion or aqueous solution obtained by dispersing or dissolving 2% by weight in water as the run content is 10 or more, preferably 11 or more, for example, in the range of 10 to 13, more preferably in the range of 11 to 13. If it is. If the pH of the resulting dispersion or aqueous solution is less than 10, the liquid may not be a viscous liquid, and if it exceeds 13, sufficient alkali expression may not occur due to the alkali being too strong. When the curdlan-containing composition is added to water as a curdlan content at 2% by weight, if the pH is less than 11, the curdlan is dispersed in water, and when the pH is 11 or more, the curdlan is dispersed in water. Dissolve.
　本実施形態に係るカードラン含有組成物における顆粒化された粒子の体積平均粒径は、９０～１０００μｍの範囲であることが好ましく、１３０～１０００μｍの範囲であることがより好ましく、９０～３００μｍの範囲または１３０～３００μｍの範囲であることがさらに好ましい。顆粒化された粒子の体積平均粒径が９０μｍ未満であると、水への分散または溶解の際に凝集物が形成されやすくなる場合がある。体積平均粒径の上限については特に限定されないが、粒子径が大きくなると（例えば、１０００μｍを超えると）、水への分散に時間を要し、カードランの分散液または溶解液が形成されにくい場合がある。顆粒化された粒子の体積平均粒径および粒度分布は、レーザー回折式粒度分布測定装置（マルバーン社製、マスターサイザー）を用いて、測定することができる。 The volume average particle diameter of the granulated particles in the curdlan-containing composition according to this embodiment is preferably in the range of 90 to 1000 μm, more preferably in the range of 130 to 1000 μm, and 90 to 300 μm. More preferably, it is in the range or in the range of 130 to 300 μm. When the volume average particle diameter of the granulated particles is less than 90 μm, an aggregate may be easily formed during dispersion or dissolution in water. The upper limit of the volume average particle size is not particularly limited, but when the particle size becomes large (for example, exceeding 1000 μm), it takes time to disperse in water, and it is difficult to form a curdlan dispersion or solution. There is. The volume average particle size and particle size distribution of the granulated particles can be measured using a laser diffraction type particle size distribution measuring device (manufactured by Malvern, Mastersizer).
　本実施形態に係るカードラン含有組成物における顆粒化された粒子において、体積平均粒径が５０μｍ以下の粒子の割合が粒子全体に対して２０％以下であり、１０％以下であることが好ましい。体積平均粒径が５０μｍ以下の粒子の割合が粒子全体に対して２０％を超えると、水への分散または溶解の際に凝集物が形成されやすくなる。また、体積平均粒径が３００μｍ以上の粒子の割合が粒子全体に対して３０％以下であり、２０％以下であることが好ましい。体積平均粒径が３００μｍ以上の粒子の割合が粒子全体に対して３０％を超えると、水への分散に時間を要し、高濃度のカードランの分散液または溶解液が形成されにくくなる。粒子全体に対する体積平均粒径が５０μｍ以下の粒子の割合、および体積平均粒径が３００μｍ以上の粒子の割合は、乾式レーザー回折式粒度分布測定装置を用いて測定した粒度分布より求めることができる。例えば、所定の孔径の篩等を用いて分級する方法等により、体積平均粒径が５０μｍ以下の微粉および体積平均粒径が３００μｍ以上の粗大粉を除去して低減すればよい。 In the granulated particles in the curdlan-containing composition according to the present embodiment, the proportion of particles having a volume average particle size of 50 μm or less is 20% or less and preferably 10% or less. When the proportion of particles having a volume average particle size of 50 μm or less exceeds 20% with respect to the whole particles, aggregates are likely to be formed during dispersion or dissolution in water. Further, the proportion of particles having a volume average particle size of 300 μm or more is 30% or less, preferably 20% or less, based on the whole particles. When the proportion of particles having a volume average particle size of 300 μm or more exceeds 30% with respect to the whole particles, it takes time to disperse in water, and it becomes difficult to form a high-concentration curdlan dispersion or solution. The ratio of the particles having a volume average particle diameter of 50 μm or less and the ratio of the particles having a volume average particle diameter of 300 μm or more to the whole particles can be determined from the particle size distribution measured using a dry laser diffraction particle size distribution measuring apparatus. For example, fine powder having a volume average particle diameter of 50 μm or less and coarse powder having a volume average particle diameter of 300 μm or more may be removed and reduced by a classification method using a sieve having a predetermined pore size.
　本実施形態に係るカードラン含有組成物は、カードランおよびアルカリ塩を混合した後、造粒機、打錠機、押し出し機、流動層造粒装置等の顆粒剤製造機器を用いて、カードランおよびアルカリ塩を同一粒子内に適切な配合や組成を施して含まれるように顆粒剤化することによって得ることができる。Ｖ型混合機やナウターミキサー等の粉末混合機で粉体を均質混合や、ヘンシェルミキサー等で微粉化して粉砕混合した配合物においては、カードランおよびアルカリ塩が粒子内で一体化していないことから、分散または溶解の際に十分な上記効果が得られない。したがって、これらの製造機器は、本実施形態に係るカードラン含有組成物を製造するための機器に含まれない。 The curdlan-containing composition according to this embodiment is prepared by mixing curdlan and an alkali salt, and then using a granule manufacturing apparatus such as a granulator, a tableting machine, an extruder, a fluidized bed granulator, etc. And an alkali salt can be obtained by granulating them so as to be contained in the same particles with appropriate blending and composition. Curdlan and alkali salts must not be integrated in the particles in a mixture in which the powder is homogeneously mixed with a powder mixer such as a V-type mixer or Nauta mixer, or pulverized and mixed with a Henschel mixer. Therefore, sufficient effects cannot be obtained during dispersion or dissolution. Therefore, these manufacturing apparatuses are not included in the apparatus for manufacturing the curdlan-containing composition according to the present embodiment.
　本実施形態に係るカードラン含有組成物中、カードランの含有量は、１０～９０重量％の範囲とすることができる。カードランの含有量が１０重量％未満では、本組成物を使用した対象物において、カードランの十分な効果が発揮および確認されない場合があり、またカードランの含有量が９０重量％を超えると、アルカリ塩の十分な効果が得られにくくなり、略均質な粒子または粘調液を形成しにくくなると考えられる。本実施形態に係るカードラン含有組成物によれば、従来の方法では困難であった、高濃度カードランの分散液を容易に作製することができる。 In the curdlan-containing composition according to the present embodiment, the curdlan content can be in the range of 10 to 90% by weight. When the content of curdlan is less than 10% by weight, in the object using this composition, the sufficient effect of curdlan may not be exhibited and confirmed, and when the content of curdlan exceeds 90% by weight It is considered that sufficient effects of the alkali salt are difficult to obtain and it is difficult to form substantially uniform particles or viscous liquid. According to the curdlan-containing composition according to the present embodiment, it is possible to easily produce a high-concentration curdlan dispersion, which has been difficult with conventional methods.
　本実施形態に係るカードラン含有組成物において、カードランの含有量（重量）を１００とした場合、アルカリ塩の含有量（重量）は、１０以上であり、２０以上であることが好ましい。カードランの含有量（重量）を１００とした場合、アルカリ塩の含有量（重量）が１０未満であると、カードランが均質に分散しない場合がある。カードランの含有量に対するアルカリ塩の含有量の上限については特に限定されない。アルカリ塩の含有量が多くなると相対的に組成物中のカードランの含有割合が減少し、カードランの十分な効果が発揮および確認されない場合がある。 In the curdlan-containing composition according to this embodiment, when the curdlan content (weight) is 100, the alkali salt content (weight) is 10 or more, preferably 20 or more. When the content (weight) of curdlan is 100, when the content (weight) of alkali salt is less than 10, the curdlan may not be uniformly dispersed. The upper limit of the alkali salt content relative to the curdlan content is not particularly limited. When the content of the alkali salt is increased, the curdlan content in the composition is relatively decreased, and the sufficient effect of the curdlan may not be exhibited and confirmed.
　本実施形態に係るカードラン含有組成物は、水に高濃度で短時間に容易に分散または溶解させることができる。例えば、ホモジナイザーや高速ミキサー等の高速撹拌装置を使用しなくても、３～５５℃の水に対して３０分以内、例えば３０秒～３０分間で、２５重量％以下、例えば１～２５重量％の量で分散または溶解させることができる。本実施形態に係るカードラン含有組成物の使用の際、分散時、溶解時、撹拌時、および製品製造時等において、加温等の温度調整を行ってもよい。加温は、カードラン含有組成物が分散または溶解しやすい温度、例えば、４０～５０℃程度とすればよい。 The curdlan-containing composition according to this embodiment can be easily dispersed or dissolved in water at a high concentration in a short time. For example, even without using a high-speed stirring device such as a homogenizer or a high-speed mixer, the water is 3 to 55 ° C within 30 minutes, for example, 30 seconds to 30 minutes. Can be dispersed or dissolved. When using the curdlan-containing composition according to this embodiment, temperature adjustment such as heating may be performed during dispersion, dissolution, stirring, product production, and the like. The heating may be a temperature at which the curdlan-containing composition is easily dispersed or dissolved, for example, about 40 to 50 ° C.
