Description

本発明は、水に容易に均一分散し、かつ低温・高温の過酷な条件下で長期間保存しても結晶や沈殿を生じることがない高い安定性を有する高結晶性物質含有組成物、及び高結晶性物質含有組成物を含有する飲食品、または化粧品に関する。   The present invention comprises a highly crystalline material-containing composition that is easily dispersed uniformly in water and has high stability that does not produce crystals or precipitates even when stored under severe conditions of low and high temperatures, and The present invention relates to a food or drink containing a highly crystalline substance-containing composition, or a cosmetic.

高結晶性物質の中には生体にとって重要な働きをもつものが多数存在する。水難溶性アミノ酸、γ−オリザノール、葉酸、ビタミンBなど、恒常的な摂取が望ましいものも多く、これを食品に適用することには大きな需要がある。しかしながら、その利用を妨げているのは高結晶性物質の結晶性、水性媒体や油性媒体への分散性が悪いことが挙げられる。そこで、これらの問題を解決する方法として、乳化剤及び油を用いて大豆油不けん化物を水中油型エマルジョンとする手法(例えば、特許文献1参照。)や、ポリグリセリン脂肪酸エステル等の乳化剤を用いて長期間保存しても均質な乳化、分散または可溶化状態を保つ植物ステロールの水溶性組成物(例えば、特許文献2参照。)等が開示されている。 There are many highly crystalline substances that have important functions for living organisms. There are many things such as poorly water-soluble amino acids, γ-oryzanol, folic acid, and vitamin B 1 that are desirable for constant consumption, and there is a great demand for applying them to foods. However, it is impeded that the crystallinity of highly crystalline substances and the dispersibility in aqueous and oily media are poor. Therefore, as a method for solving these problems, a method of making a soybean oil unsaponifiable product into an oil-in-water emulsion using an emulsifier and oil (for example, see Patent Document 1), or an emulsifier such as polyglycerin fatty acid ester is used. In addition, a water-soluble composition of plant sterols that maintains a homogeneous emulsified, dispersed or solubilized state even after long-term storage (see, for example, Patent Document 2) is disclosed.

一方、製品中で高結晶性物質の結晶化が進行すると乳化破壊による内容の不均一化、食品への分散性の低下、生体への吸収性阻害、見た目の悪化を引き起こし、製品価値を大きく低下させてしまうこととなることから、強分散性の乳化装置を用いる手法が、脂溶性の高結晶性物質を水中に均一、かつ経時的に安定分散させる上で望まれている。そこで、高圧乳化機等の強分散性の乳化装置を使用し乳化処理を行なうことで、カロチノイド色素を水中に均一、かつ経時的に安定に分散させる手法(例えば、特許文献3参照。)等が開示されている。   On the other hand, as crystallization of highly crystalline substances progresses in the product, the content becomes uneven due to emulsion breakage, the dispersibility in foods decreases, the absorption to the living body is inhibited, and the appearance deteriorates, greatly reducing the product value. Therefore, a technique using a strongly dispersible emulsifying device is desired to uniformly disperse a fat-soluble highly crystalline substance in water uniformly over time. Accordingly, there is a technique (for example, see Patent Document 3) in which a carotenoid pigment is uniformly dispersed in water stably over time by performing emulsification using a highly dispersible emulsifier such as a high-pressure emulsifier. It is disclosed.

しかしながら、現在市販されている一般のポリグリセリン脂肪酸エステルは、1級水酸基の割合が50重量%未満であり、環状体を多く含んでいる。そのポリグリセリンと脂肪酸とのエステルでは高い乳化、可溶化力は発揮することができず、さらに、環状物の存在によって高結晶性物質を安定に水中へ分散させることを妨げるという問題がある。また、使用目的に併せてポリグリセリンの親水基の構造まで考慮して設計されておらず、ポリグリセリン中の環状体について着目した手法はない。   However, general polyglycerin fatty acid esters currently on the market have a primary hydroxyl group content of less than 50% by weight and contain a large amount of cyclic products. The ester of polyglycerin and fatty acid cannot exhibit high emulsification and solubilizing power, and further has a problem of preventing the high crystalline substance from being stably dispersed in water due to the presence of the cyclic product. Moreover, it is not designed considering the structure of the hydrophilic group of polyglycerin according to the purpose of use, and there is no technique that focuses on the cyclic body in polyglycerin.

一方、強分散性の高圧乳化機を用いる手法は、いかなる生産ラインにも高圧乳化機が設置されているとは限らず汎用性が低く、設置されていたとしても原料の混合釜からラインを通じて高圧乳化機まで混合原料を移送させる必要があり、その間にラインコンタミネーションの可能性が高まることによる品質の劣化、それに伴うクレーム発生の危険性が高い。また高圧で乳化させるため、エネルギーの消費は高く、必ずしも生産性の高い手法であるとはいい難い。   On the other hand, the technique using a high-dispersion high-pressure emulsifier is not necessarily equipped with a high-pressure emulsifier in any production line, and is less versatile. It is necessary to transfer the mixed raw material to the emulsifier, and during that time, there is a high risk of quality deterioration due to an increase in the possibility of line contamination and the associated complaints. In addition, since it is emulsified at a high pressure, energy consumption is high and it is difficult to say that the method is necessarily highly productive.

また、高結晶性物質は、一般的に植物油などの液状油に加熱溶解した後、乳化の操作を行う方法が取られるが、その結晶性故に溶解状態を維持しながら乳化させることは難しい。また、一時的に乳化、可溶化分散しても、飲料などで想定されるような酸性溶液やアルコール溶液での低温、高温保存を繰り返すことにより濁りや結晶を生じ、乳化破壊を起こすという問題点がある。このような高結晶性物質は、安定分散が極めて困難であり、食品用途、化粧品用途における汎用性が極めて低い。   In addition, a highly crystalline substance is generally dissolved in a liquid oil such as vegetable oil by heating and then emulsified, but it is difficult to emulsify while maintaining a dissolved state because of its crystallinity. In addition, even if temporarily emulsified and solubilized and dispersed, problems such as turbidity and crystals occur due to repeated low-temperature and high-temperature storage in an acidic solution or alcohol solution as expected in beverages and the like, causing emulsion breakage. There is. Such a highly crystalline substance is extremely difficult to stably disperse and has extremely low versatility in food and cosmetic applications.

よって、これらの方法では、高結晶性物質の安定な乳化、可溶化状態を長期間保つことができ、安心して飲食品や化粧品に配合できる組成物として十分に満足しうるものは調製することは難しい。   Therefore, in these methods, it is possible to maintain a stable emulsification and solubilization state of a highly crystalline substance for a long period of time, and it is possible to prepare a composition that can be satisfactorily satisfied as a composition that can be blended in foods and beverages and cosmetics with confidence. difficult.

従って、本発明は前記従来技術に鑑みてなされたものであり、本発明の課題は、高結晶性物質を水に容易に均一分散でき、かつ低温・高温の過酷な条件下で長期間保存しても結晶や沈殿を生じない高い安定性を有し、さらに耐酸性、耐塩性、耐熱性、耐アルコール性に優れた高結晶性物質含有組成物、ならびに前記組成物を含有する飲食品、または化粧品を提供することにある。   Accordingly, the present invention has been made in view of the above-described prior art, and an object of the present invention is to easily and uniformly disperse a highly crystalline substance in water, and to store it for a long time under severe conditions of low and high temperatures. A highly crystalline substance-containing composition having high stability that does not cause crystal or precipitation, and excellent in acid resistance, salt resistance, heat resistance, and alcohol resistance, and a food or drink containing the composition, or To provide cosmetics.

本発明者らは、上記課題を解決するため鋭意検討した結果、優れた結晶抑制効果、乳化、可溶化効果をもった特殊なポリグリセリン脂肪酸エステルと、結晶を溶解、安定化させる為の特定された液状油とを用いることによって、特殊な乳化装置を用いることなく高結晶性物質含有組成物を得る事ができ、また、乳化後に結晶析出などが起こらず、飲食品に添加する際に必要とされる耐酸性、耐塩性、耐熱性、耐アルコール性が共にすぐれ、長期保存、特に低温保存においてにおいても安定な乳化、または可溶化状態を保つ高結晶性物質含有組成物が得られることを見出し、本発明を完成した。   As a result of intensive studies to solve the above-mentioned problems, the present inventors have identified a special polyglycerin fatty acid ester having an excellent crystallization inhibiting effect, emulsification and solubilizing effect, and for dissolving and stabilizing crystals. By using the liquid oil, a highly crystalline substance-containing composition can be obtained without using a special emulsifier, and crystal precipitation does not occur after emulsification. It has been found that a highly crystalline substance-containing composition that maintains excellent acid resistance, salt resistance, heat resistance, and alcohol resistance, and maintains stable emulsification or solubilization even in long-term storage, particularly low-temperature storage. The present invention has been completed.

本発明の高結晶性物質含有組成物に用いるポリグリセリン脂肪酸エステルに用いるポリグリセリンは、水酸基価が1200以下であり、かつ全ての水酸基のうち1級水酸基が50重量%以上であり、さらに環状体含量が25重量%以下であるポリグリセリンと脂肪酸とがエステル化されていることに一つの大きな特徴を有する。   The polyglycerin used in the polyglycerin fatty acid ester used in the highly crystalline substance-containing composition of the present invention has a hydroxyl value of 1200 or less, a primary hydroxyl group of 50% by weight or more of all the hydroxyl groups, and a cyclic product. One major characteristic is that polyglycerin having a content of 25% by weight or less and a fatty acid are esterified.

以上のような特徴を有することにより、本発明の高結晶性物質含有組成物に用いるポリグリセリン脂肪酸エステルは高結晶性物質の水分散性の付与に優れ、かつ結晶化を抑制する界面活性剤として使用することができるものである。すなわち従来のポリグリセリン脂肪酸エステル、および食品用界面活性剤では性能が不十分であり代替できるものではない。   By having the characteristics as described above, the polyglycerin fatty acid ester used in the highly crystalline substance-containing composition of the present invention is excellent in imparting water dispersibility of the highly crystalline substance and as a surfactant that suppresses crystallization. It can be used. That is, conventional polyglycerin fatty acid esters and food surfactants have insufficient performance and cannot be replaced.

ポリグリセリン脂肪酸エステルにおけるポリグリセリンとは、グリセリンを脱水縮合するなどして得られるグリセリン骨格を基本単位として分子内に水酸基とエーテル結合を有している物質をいう。   The polyglycerol in the polyglycerol fatty acid ester refers to a substance having a hydroxyl group and an ether bond in the molecule with a glycerol skeleton obtained by dehydration condensation of glycerol as a basic unit.

本発明に用いるポリグリセリン脂肪酸エステルにおけるポリグリセリンは、分子中の全ての水酸基のうち1級水酸基が50重量%以上であるポリグリセリンであり、得られるポリグリセリン脂肪酸エステルの可溶化性能および乳化安定性をさらに向上する観点から、1級水酸基が好ましくは55重量%以上のポリグリセリン、より好ましくは60重量%以上のポリグリセリンである。さらに上限値は、特に規定するものではないが、その効果を最大限に発揮させるためには90重量%以下であることが望ましい。本願のポリグリセリンにおける全水酸基のうち1級水酸基の占める割合はポリグリセリンの縮合度に応じて変化するため、また一般的に流通しているポリグリセリンの種類がテトラ、ペンタ、ヘキサ、デカであることを考慮してその上限値を例示するならば、テトラグリセリンでは70重量%以下、好ましくは65重量%以下、ペンタグリセリンでは75重量%以下、好ましくは70重量%以下、ヘキサグリセリンでは80重量%以下、好ましくは75重量%以下、デカグリセリンでは85重量%以下、好ましくは80重量%以下といった数値を示すことができる。   The polyglycerol in the polyglycerol fatty acid ester used in the present invention is a polyglycerol having a primary hydroxyl group of 50% by weight or more among all the hydroxyl groups in the molecule. Solubilization performance and emulsion stability of the resulting polyglycerol fatty acid ester From the viewpoint of further improving the above, the primary hydroxyl group is preferably 55% by weight or more of polyglycerol, more preferably 60% by weight or more of polyglycerol. Further, the upper limit value is not particularly specified, but is desirably 90% by weight or less in order to maximize the effect. The proportion of primary hydroxyl groups in the total hydroxyl groups in the polyglycerol of the present application changes depending on the degree of condensation of the polyglycerols, and the types of polyglycerols that are generally distributed are tetra, penta, hexa, and deca. In consideration of this, the upper limit value is exemplified by tetraglycerin 70 wt% or less, preferably 65 wt% or less, pentaglycerin 75 wt% or less, preferably 70 wt% or less, and hexaglycerin 80 wt%. In the following, numerical values such as preferably 75% by weight or less, decaglycerin 85% by weight or less, preferably 80% by weight or less can be shown.

また、ポリグリセリンの水酸基価は、1200以下であり、用途に応じてポリグリセリン脂肪酸エステルの親水性(HLB)を調整できる観点から、1100以下がより好ましく、1000以下がさらに好ましい。また、作業性および脂肪酸とのエステル化の容易性の観点から、水酸基価は770以上が好ましい。   Moreover, the hydroxyl value of polyglycerol is 1200 or less, 1100 or less are more preferable from a viewpoint which can adjust the hydrophilicity (HLB) of polyglycerol fatty acid ester according to a use, and 1000 or less are further more preferable. Further, from the viewpoint of workability and ease of esterification with a fatty acid, the hydroxyl value is preferably 770 or more.

全ての水酸基のうちの1級水酸基の割合は、炭素原子に対する核磁気共鳴スペクトル(NMR)を測定する方法を用いて測定される。また、水酸基価は当該分野で公知の方法により測定することができる。   The proportion of primary hydroxyl groups among all hydroxyl groups is measured using a method of measuring a nuclear magnetic resonance spectrum (NMR) for carbon atoms. The hydroxyl value can be measured by a method known in the art.

なお、炭素原子に対する核磁気共鳴スペクトル(NMR)は、以下のようにして測定することができる。ポリグリセリン500mgを重水2.8mlに溶解し、ろ過後ゲートつきデカップリングにより13C−NMR(125MHz)スペクトルを得る。ゲートデカップルド測定手法によりピーク強度は炭素数に比例する。1級水酸基と2級水酸基の存在を示す13C化学シフトはそれぞれメチレン炭素(CHOH)が63ppm付近、メチン炭素(CHOH)が71ppm付近であり、2種それぞれのシグナル強度の分析により、1級水酸基と2級水酸基の存在比を算出する。但し、2級水酸基を示すメチン炭素(CHOH)は、1級水酸基を示すメチレン炭素に結合するメチン炭素にさらに隣接するメチレン炭素ピークと重なり、それ自体の積分値を得られないため、メチン炭素(CHOH)と隣り合うメチレン炭素(CH)の74ppm付近のシグナル強度により積分値を算出する。 In addition, the nuclear magnetic resonance spectrum (NMR) with respect to a carbon atom can be measured as follows. Polyglycerin 500 mg is dissolved in 2.8 ml of heavy water, and after filtration, 13 C-NMR (125 MHz) spectrum is obtained by gated decoupling. The peak intensity is proportional to the carbon number by the gate decoupled measurement method. The 13 C chemical shifts indicating the presence of primary hydroxyl groups and secondary hydroxyl groups are about 63 ppm for methylene carbon (CH 2 OH) and about 71 ppm for methine carbon (CHOH), respectively. The abundance ratio of the primary hydroxyl group and the secondary hydroxyl group is calculated. However, the methine carbon (CHOH) indicating the secondary hydroxyl group overlaps with the methylene carbon peak further adjacent to the methine carbon bonded to the methylene carbon indicating the primary hydroxyl group, and the integral value of itself cannot be obtained. The integrated value is calculated from the signal intensity around 74 ppm of methylene carbon (CH 2 ) adjacent to (CHOH).

さらに、ポリグリセリンの環状体含有量が高結晶性物質の安定な水分散性の観点から、ポリグリセリン中25重量%以下であり、好ましくは5〜20重量%、より好ましくは5〜10重量%である。本明細書において、環状体含量とは液体クロマトグラフ−質量分析計(LC/MS)法を用いて測定される含有量のことをいい、後述の実施例に記載の方法により算出される。   Furthermore, from the viewpoint of the stable water dispersibility of the highly crystalline substance, the polyglycerin cyclic body content is 25% by weight or less, preferably 5 to 20% by weight, more preferably 5 to 10% by weight. It is. In the present specification, the cyclic content refers to the content measured using a liquid chromatograph-mass spectrometer (LC / MS) method, and is calculated by the method described in the examples below.

また、ポリグリセリン調製方法は限定するものではないが、例えば、脱水縮合法、市販のポリグリセリンから分画精製または合成法の工夫などにより得る事ができるが、容易に環状体含量を低く抑えることができるという点でグリシドール開環重合法が好適である。   The method for preparing polyglycerol is not limited. For example, it can be obtained from dehydration condensation, commercially available polyglycerol by fractional purification or synthesis method, etc., but it is easy to keep the cyclic content low.

ポリグリセリン脂肪酸エステルのもう一つの構成成分である脂肪酸は天然の動植物より抽出した油脂を加水分解し、分離してあるいは分離せずに精製して得られるカルボン酸を官能基として含む物質であれば特に限定するものではない。あるいは石油などを原料にして化学的に合成して得られる脂肪酸であってもよい。あるいはまた、これら脂肪酸を水素添加などして還元したものや、水酸基を含む脂肪酸を縮重合して得られる縮合脂肪酸や、不飽和結合を有する脂肪酸を加熱重合して得られる重合脂肪酸であってもよい。これら脂肪酸の選択に当たっては所望の効果を勘案して適宜決めればよい。本発明に用いる脂肪酸の具体例としては、炭素数6〜22の飽和あるいは不飽和の脂肪酸、即ち、カプロン酸、カプリル酸、カプリン酸、ラウリン酸、ミリスチン酸、パルミチン酸、パルミトオレイン酸、ステアリン酸、イソステアリン酸、オレイン酸、リノール酸、リノレン酸、ベヘニン酸、エルカ酸の他、分子中に水酸基を有するリシノール酸、12−ヒドロキシステアリン酸及びこれらの縮合物などが挙げられるが、なかでも乳化安定性の面からラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸、イソステアリン酸、オレイン酸、縮合リシノール酸が好ましく、ミリスチン酸、パルミチン酸、ステアリン酸、オレイン酸がより好ましい。エステル化度については特に限定するものではないが、モノエステル含有量の高い、低エステル化度のものが好ましい。   Fatty acid, which is another component of polyglycerin fatty acid ester, is a substance containing a carboxylic acid as a functional group obtained by hydrolyzing and extracting oils and fats extracted from natural animals and plants. There is no particular limitation. Alternatively, it may be a fatty acid obtained by chemically synthesizing petroleum or the like as a raw material. Alternatively, these fatty acids may be reduced by hydrogenation or the like, condensed fatty acids obtained by condensation polymerization of fatty acids containing hydroxyl groups, or polymerized fatty acids obtained by heat polymerization of fatty acids having unsaturated bonds. Good. The selection of these fatty acids may be appropriately determined in consideration of the desired effect. Specific examples of fatty acids used in the present invention include saturated or unsaturated fatty acids having 6 to 22 carbon atoms, that is, caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitooleic acid, stearin.

ポリグリセリンと脂肪酸とのエステル化は、当該分野で公知の方法に従って行われる。例えばアルカリ触媒下、酸触媒下、あるいは無触媒下にて、常圧あるいは減圧下エステル化することができる。また、ポリグリセリンと脂肪酸の混合量を変更することにより種々の性質をもつポリグリセリン脂肪酸エステルを調製することができる。例えば、親水性の界面活性剤に使用するためのポリグリセリン脂肪酸エステルを得る場合、ポリグリセリンの水酸基価と脂肪酸の分子量から計算により等モルになるように重量を計算してポリグリセリンと脂肪酸を仕込めばよく、親油性の界面活性剤に使用するためのポリグリセリン脂肪酸エステルを得る場合、脂肪酸のモル数を増加させればよい。得られたポリグリセリン脂肪酸エステルは使用される製品の使用上の要求によってさらに精製してもよい。精製の方法は公知のいかなる方法でもよく特に限定するものではない。たとえば、活性炭や活性白土などにて吸着処理したり、水蒸気、窒素などをキャリアーガスとして用いて減圧下脱臭処理を行ったり、あるいは酸やアルカリを用いて洗浄を行ったり、分子蒸留を行ったりして精製してもよい。   Esterification of polyglycerol and fatty acid is performed according to a method known in the art. For example, the esterification can be performed under normal pressure or reduced pressure in the presence of an alkali catalyst, an acid catalyst, or no catalyst. Moreover, the polyglycerol fatty acid ester which has various properties can be prepared by changing the mixing amount of polyglycerol and a fatty acid. For example, when obtaining a polyglycerin fatty acid ester for use in a hydrophilic surfactant, the polyglycerin and the fatty acid are charged by calculating the weight so as to be equimolar by calculation from the hydroxyl value of the polyglycerin and the molecular weight of the fatty acid. What is necessary is just to increase the number-of-moles of a fatty acid, when obtaining the polyglyceryl fatty acid ester for using for lipophilic surfactant. The resulting polyglycerol fatty acid ester may be further purified according to the usage requirements of the product used. The purification method may be any known method and is not particularly limited. For example, adsorption treatment with activated carbon or activated clay, deodorization treatment under reduced pressure using water vapor or nitrogen as a carrier gas, washing with acid or alkali, or molecular distillation. And may be purified.

本発明の高結晶性物質含有組成物において、該組成物が飲食品中に均一かつ長期的に安定に分散することは勿論であるが、さらに多価アルコールを用いることによってハンドリング性、製剤安定性、水分散時の安定性が向上する。この場合の多価アルコールとしては特に限定するものではないが、1分子中に水酸基を2個以上有する化合物の総称であり、プロピレングリコール、ジプロピレングリコール、グリセリン、ジグリセリン、トリグリセリン、ポリグリセリン、エチレングリコール、ジエチレングリコール、ポリエチレングリコール、3−メチル−1,3−ブタンジオール、1,3−ブチレングリコール、ソルビトール、キシリトール、マルチトール、ラクチトール、ソルビタン、キシロース、アラビノース、マンノース、乳糖、砂糖、カップリングシュガー、ブドウ糖、酵素水飴、酸糖化水飴、麦芽糖水飴、麦芽糖、異性化糖、果糖、還元麦芽糖水飴、還元澱粉糖水飴、蜂蜜、果糖ブドウ糖液糖、およびこれらの溶液が例示でき、これらは単独でも2種以上を組み合わせて使用してもよい。なかでも製剤の調製のしやすさ、安定性からプロピレングリコール、グリセリン、ジグリセリン、トリグリセリン、ポリグリセリンが好適に使用でき、さらにプロピレングリコール、グリセリンが食品に使用できるという観点からも望ましい。   In the highly crystalline substance-containing composition of the present invention, it is of course possible that the composition is uniformly and stably dispersed in food and drink for a long period of time. , Stability during water dispersion is improved.

さらに、本発明品の高結晶性物質含有組成物を多価アルコール中油型(O/D型)の乳化物とすることによって、水に容易に分散でき、また経時的に結晶や沈殿などを生じない組成物とすることができる。   Furthermore, by making the highly crystalline substance-containing composition of the present invention into an oil-in-polyhydric alcohol (O / D type) emulsion, it can be easily dispersed in water, and crystals and precipitates are produced over time. No composition.

本発明中の多価アルコール中油型(O/D型)乳化は、界面活性剤の多価アルコール溶液中に油成分を分散させたものであり、油と多価アルコールが界面活性剤を介して両連続構造(バイコンティニュアス構造)を有していると考えられる。高結晶性の物質を含有する組成物が両連続構造を有する場合、強力な撹拌力がなくても容易にナノミセルを形成することが可能となるだけでなく、高結晶性の物質を同時にナノミセル中にカプセル化することが可能になると推定される。従来、高結晶性物質をそのまま飲食品、または化粧品中へ配合する場合には、高結晶性物質は析出しない程度にしか配合することができなかった。しかし、本組成物はバイコンティニュアス構造を有しているので、飲食品、または化粧品への安定かつ透明性を有した状態で高結晶性物質を高配合することが可能であり、よって付加価値の高い飲料などの水系食品、または化粧水、乳液などの化粧品を調製することが可能であることが判明した。なお、組成物が両連続構造を有しているかどうかは、界面活性剤と多価アルコールと油で3成分系の相図を作成することで容易に識別することができる。   The oil-in-polyol (O / D-type) emulsification in the present invention is obtained by dispersing an oil component in a polyhydric alcohol solution of a surfactant, and the oil and the polyhydric alcohol are passed through the surfactant. It is thought that it has a bicontinuous structure (bicontinuous structure). When a composition containing a highly crystalline substance has a bicontinuous structure, it becomes possible not only to form nano micelles easily without a strong stirring force, but also to a highly crystalline substance simultaneously in the nano micelles. It is presumed that it becomes possible to encapsulate. Conventionally, when a highly crystalline substance is blended as it is into a food or drink product or cosmetic, it can be blended only to such an extent that the highly crystalline substance does not precipitate. However, since this composition has a bicontinuous structure, it is possible to add a high crystalline substance in a stable and transparent state to foods and beverages or cosmetics. It has been found that it is possible to prepare water-based foods such as high-value beverages or cosmetics such as lotions and emulsions. Whether or not the composition has a bicontinuous structure can be easily identified by creating a three-component phase diagram with a surfactant, a polyhydric alcohol, and oil.

For example, propeller type, anchor type, paddle type agitator, rotor / stator type emulsifier that can give stronger shearing force, mill type emulsifier with grinding function, high pressure nozzle type emulsifier that generates cavitation at high pressure , High-pressure collision emulsifiers that collide liquids under high pressure, and emulsify by impact force, shear force due to turbulent flow and cavitation, ultrasonic emulsifiers that generate cavitation with ultrasonic waves, membrane emulsification that uniformly emulsifies through pores Examples thereof include a static mixer that repeats a dispersed assembly of liquids in a machine and an element and uniformly mixes them.

The cosmetic is not particularly limited, and examples thereof include lotion, emulsion, shampoo, rinse, hair cosmetic, foundation, lipstick, and moisturizing cream.

本発明の飲食品、または化粧品は、例えば、既成の飲食品に対して本発明の高結晶性物質含有組成物を添加することにより得られるが、それらの飲食品、または化粧品を調製する際に、本発明の組成物を使用原料に予め添加するか、若しくは調製工程中に共に配合することにより、調製することができる。本発明の所望の効果を発現しうる飲食品、または化粧品が得られるのであれば、該製品への本発明の組成物の添加時期や添加方法については特に限定するものではない。   The food / beverage products or cosmetics of the present invention can be obtained, for example, by adding the highly crystalline substance-containing composition of the present invention to an existing food / beverage product. It can be prepared by adding the composition of the present invention to the raw materials used in advance or by blending it together during the preparation process. If the food / beverage products or cosmetics which can express the desired effect of this invention are obtained, it will not specifically limit about the addition time and addition method of the composition of this invention to this product.

本発明の高結晶性物質含有組成物を含有してなる飲食品は、高結晶性物質が安定に分散しているため、本発明の飲食品、または化粧品は、高結晶性物質の析出による結晶、白濁、沈殿等が認められず、ざらつきや油っぽさがない。特に、飲食品で想定される塩、酸、アルコール溶液中での安定性にすぐれ、高温、低温を繰り返すような劣悪な流通、保管条件でも結晶の発生がないため、商品の外観、食感、使用感を悪化させることなく、高結晶性物質を飲食品、または化粧品に付与することができる。中でも、スポーツドリンク、機能性飲料、茶飲料などの飲料類は透明性を重視されるが、本発明の組成物は高結晶性物質が安定に乳化若しくは可溶化されているので、飲料等の透明感を損ねることなく、高結晶性物質を飲料に高配合することができる。   Since the food / beverage product containing the highly crystalline substance-containing composition of the present invention has a high crystalline substance dispersed stably, the food / beverage product or cosmetic of the present invention is a crystal formed by precipitation of the highly crystalline substance.

A highly crystalline substance can be imparted to a food or drink or a cosmetic without deteriorating the feeling of use. Among these, beverages such as sports drinks, functional beverages, and tea beverages are regarded as transparent, but the composition of the present invention has a highly crystalline substance stably emulsified or solubilized, so that beverages and the like are transparent. A highly crystalline substance can be highly blended in a beverage without impairing the feeling.

本発明の飲食品、または化粧品における本発明の高結晶性物質含有組成物の含有量は、本発明の目的が阻害されない範囲内で配合されていればよく、特に限定するものではないが、使用する乳化剤が飲食品の風味、化粧品の使用感に影響を与えないという観点から、好ましくは0.005〜50重量%、より好ましくは0.01〜20重量%、さらに好ましくは0.1〜10重量%であることが望ましい。   The content of the highly crystalline substance-containing composition of the present invention in the food / beverage product or cosmetic of the present invention is not particularly limited as long as the content of the present invention is not impaired. From the viewpoint that the emulsifying agent does not affect the flavor of the food and drink and the feeling of use of cosmetics, it is preferably 0.005 to 50% by weight, more preferably 0.01 to 20% by weight, and still more preferably 0.1 to 10%. It is desirable to be weight percent.

以下、実施例を示して本発明を具体的に説明するが、本発明は下記実施例に制限されるものではない。   EXAMPLES Hereinafter, although an Example is shown and this invention is demonstrated concretely, this invention is not restrict | limited to the following Example.

実施例1〜24及び比較例1〜12
表2〜4に示す界面活性剤及び液状油をビーカーに入れ、80℃に加温した後、ホモミキサーを用いて6000r/minで攪拌して混合した。得られた混合物に表2〜4に示す高結晶性物質を加えさらに加熱、攪拌して混合した。高結晶性物質が完全に溶解し、溶液が透明になっていることを目視にて確認後、予め別のビーカーにて80℃に加温しておいた多価アルコールを加え、さらに、表2〜4の配合に応じて水またはアルコールを加え、6000rpmにて攪拌混合し、実施例1〜24及び比較例1〜12の組成物を得た。なお、用いたポリグリセリン脂肪酸エステルのHLB、そのポリグリセリンの水酸基価、1級水酸基含量および環状体含量は表1に示すとおりである。
Examples 1-24 and Comparative Examples 1-12
The surfactant and liquid oil shown in Tables 2 to 4 were put into a beaker, heated to 80 ° C., and then stirred and mixed at 6000 r / min using a homomixer. Highly crystalline substances shown in Tables 2 to 4 were added to the resulting mixture, and the mixture was further heated and stirred to mix. After visually confirming that the highly crystalline substance is completely dissolved and the solution is transparent, polyhydric alcohol previously heated to 80 ° C. in another beaker was added, and Table 2 Water or alcohol was added according to the formulation of ˜4, and the mixture was stirred and mixed at 6000 rpm to obtain compositions of Examples 1 to 24 and Comparative Examples 1 to 12. The HLB of the polyglycerin fatty acid ester used, the hydroxyl value of the polyglycerin, the primary hydroxyl group content and the cyclic body content are as shown in Table 1.

なお、用いたポリグリセリンの環状体含有量は、以下に示す条件で液体クロマトグラフ−質量分析計(LC/MS)を用いて分析した。   In addition, the cyclic body content of the used polyglycerol was analyzed using the liquid chromatograph-mass spectrometer (LC / MS) on the conditions shown below.

Injection volume: 10 μl, 100 ppm
Analysis time: 20 minutes

また、用いたポリグリセリンの水酸基価は、第7版食品添加物工程書「油脂類試験法」に準じて算出した。   Moreover, the hydroxyl value of the used polyglycerol was computed according to the 7th edition food additive process manual "Oil and fats test method".

1級水酸基の割合は、核磁気共鳴装置におけるスペクトル分析にて決定した。すなわち核磁気共鳴装置(13C−NMR:日本電子社製、JNM−A500)を使用して、ポリグリセリンの1級水酸基と2級水酸基の割合を分析した。ポリグリセリン500mgを重水2.8mlに溶解し、ろ過後ゲートつきデカップリングにより13C−NMR(125MHz)スペクトルを得る。ゲートデカップルド測定手法によりピーク強度は炭素数に比例する。1級水酸基と2級水酸基の存在を示す13C化学シフトはそれぞれメチレン炭素(CHOH)が63ppm付近、メチン炭素(CHOH)が71ppm付近であり、2種それぞれのシグナル強度の分析により、1級水酸基と2級水酸基の存在比を算出する。但し、2級水酸基を示すメチン炭素(CHOH)は、1級水酸基を示すメチレン炭素に結合するメチン炭素にさらに隣接するメチレン炭素ピークと重なり、それ自体の積分値を得られないため、メチン炭素(CHOH)と隣り合うメチレン炭素(CH)の74ppm付近のシグナル強度により積分値を算出した。 The proportion of primary hydroxyl groups was determined by spectral analysis using a nuclear magnetic resonance apparatus. That is, using a nuclear magnetic resonance apparatus ( 13 C-NMR: JNM-A500, manufactured by JEOL Ltd.), the ratio of primary hydroxyl groups and secondary hydroxyl groups of polyglycerol was analyzed. Polyglycerin 500 mg is dissolved in 2.8 ml of heavy water, and after filtration, 13 C-NMR (125 MHz) spectrum is obtained by gated decoupling. The peak intensity is proportional to the carbon number by the gate decoupled measurement method. The 13 C chemical shifts indicating the presence of primary hydroxyl groups and secondary hydroxyl groups are about 63 ppm for methylene carbon (CH 2 OH) and about 71 ppm for methine carbon (CHOH), respectively. The abundance ratio of the primary hydroxyl group and the secondary hydroxyl group is calculated. However, the methine carbon (CHOH) indicating the secondary hydroxyl group overlaps with the methylene carbon peak further adjacent to the methine carbon bonded to the methylene carbon indicating the primary hydroxyl group, and the integral value of itself cannot be obtained. The integrated value was calculated from the signal intensity around 74 ppm of methylene carbon (CH 2 ) adjacent to (CHOH).

なお、本実施例に用いた被製剤化物質が常温で結晶状態であることは、偏光顕微鏡下の観察で、偏光を示すことにより確認した。   In addition, it was confirmed by observing under a polarizing microscope that the substance to be formulated used in this example was in a crystalline state at room temperature by showing polarized light.
