Description

本発明は、特に飲料に好適に用いられる、脂溶性物質、澱粉加水分解物及び低分子界面活性剤を含有する粉末組成物と、この粉末組成物の製造方法に関する。本発明はまた、この粉末組成物を含有する飲料に関する。 The present invention relates to a powder composition containing a fat-soluble substance, a starch hydrolysate, and a low molecular weight surfactant, which is particularly suitable for use in beverages, and a method for producing this powder composition. The present invention also relates to a beverage containing this powder composition.

飲食品分野において広い用途で用いられる脂溶性物質を含有する水分散性の粉末として、従来、乳化効果や膜形成のために用いられてきた乳タンパク質(脱脂乳、カゼインおよびその塩など)を用いることなく、同等以上の安定性や分散性を有する、無タンパク粉末油脂組成物の製造技術が知られている。 As a water-dispersible powder containing fat-soluble substances that has a wide range of uses in the food and beverage industry, a technology for producing a protein-free powdered oil and fat composition is known that has the same or better stability and dispersibility as milk proteins (skim milk, casein and their salts, etc.) that have traditionally been used for emulsifying effects and film formation.

例えば、食用油脂と、オクテニルコハク酸エステル化澱粉と、トレハロースとを主成分として含有することを特徴とする無タンパク粉末油脂組成物(特許文献1);融点20度以上の食用油脂、オクテニルコハク酸エステル化でんぷん、ラクトースおよびデキストリンを主成分として含有することを特徴とする無タンパク粉末油脂組成物(特許文献2);グリセリン脂肪酸エステル、ショ糖脂肪酸エステル、ソルビタン脂肪酸エステル、プロピレングリコール脂肪酸エステルおよびレシチンからなる群から選ばれる1種または2種以上の常温でペースト状もしくは液状の乳化剤20~80質量%、ならびに澱粉もしくはその加水分解物と有機酸グリセリン脂肪酸エステル(質量比100:0.1~50)、および/または乳化性澱粉誘導体もしくはその加水分解物からなる粉末化剤80~20質量%を含むことを特徴とする粉末乳化剤(特許文献3);食用油脂100質量部に対して、ヘミセルロース6.6~10質量部および高度分岐環状デキストリン34~60質量部を含有する粉末油脂組成物(特許文献4);A成分としてα-化デンプン系粉末に、B成分として油性成分を吸着させてなる油性粉末であって、前記のα-化デンプン系粉末は、粒度が10~80メッシュ、嵩比重が0.01~0.8g/cm、吸油量が1.5~1.7ml/gであり、油性成分の保持能力が2級~5級であることを特徴とする油性粉末(特許文献5);油性成分とアラビアガムおよび糖類を含み、油性成分とアラビアガムとの質量比が2:1~1:5で、かつアラビアガムと糖類との質量比が5:1~1:100であることを特徴とする粉末油脂組成物(特許文献6);水系において自発的に閉鎖小胞体を形成する両親媒性物質又は糖ポリマーの粒子を形成する糖ポリマーと、油脂成分と、賦形剤とを含んで構成され、水と混和された際、前記閉鎖小胞体又は前記糖ポリマーの粒子の作用でO/W型乳化物を形成するものである粉末油脂組成物(特許文献7);がある。 For example, there are known protein-free powdered oil and fat compositions characterized by containing as main components edible oils and fats, octenyl succinate-esterified starch, and trehalose (Patent Document 1); protein-free powdered oil and fat compositions characterized by containing as main components edible oils and fats having a melting point of 20 degrees or more, octenyl succinate-esterified starch, lactose, and dextrin (Patent Document 2); and a composition comprising 20 to 80% by mass of one or more emulsifiers that are paste-like or liquid at room temperature selected from the group consisting of glycerin fatty acid esters, sucrose fatty acid esters, sorbitan fatty acid esters, propylene glycol fatty acid esters, and lecithin, and a starch that is a paste or liquid at room temperature. A powdered emulsifier comprising 80 to 20% by mass of a powdering agent consisting of a starch powder or its hydrolysate and an organic acid glycerin fatty acid ester (mass ratio 100:0.1 to 50), and/or an emulsifying starch derivative or its hydrolysate (Patent Document 3); a powdered oil and fat composition containing 6.6 to 10 parts by mass of hemicellulose and 34 to 60 parts by mass of highly branched cyclic dextrin per 100 parts by mass of edible oil and fat (Patent Document 4); an oily powder obtained by adsorbing an α-starch-based powder as component A and an oily component as component B, the α-starch-based powder having a particle size of 10 to 80 mesh and a bulk density of 0.01 to 0.8 g/cm 3. An oil-based powder characterized by having an oil absorption of 1.5 to 1.7 ml/g and a retention capacity of oily components of grade 2 to 5 (Patent Document 5); a powdered oil composition comprising an oily component, gum arabic, and sugars, the mass ratio of the oily component to gum arabic being 2:1 to 1:5, and the mass ratio of gum arabic to sugars being 5:1 to 1:100 (Patent Document 6); a powdered oil composition comprising an amphiphilic substance that spontaneously forms closed endoplasmic reticulum in an aqueous system, or a sugar polymer that forms sugar polymer particles, an oil-based component, and an excipient, and which forms an O/W type emulsion by the action of the closed endoplasmic reticulum or the sugar polymer particles when mixed with water (Patent Document 7).

これらの文献では、用いる粉末化基材や粉末製造方法が特徴とされている。しかしながら、特徴的な粉末化基材は、溶解時の粘性や特有の臭気により、用いた食品の味質に影響を与えたり、特殊かつ高価なものであり、汎用性の面やコスト削減の面では実用化が難しい。また、粉末製造方法が特徴的な場合は、大量生産に適した既設の噴霧乾燥設備が使用できず、新たな製造設備や製造上の工夫が必要となるなど、製造コストが高くなるという問題点があった。 In these documents, the powdered base material and the powder manufacturing method used are described as being characteristic. However, the characteristic powdered base material has a viscosity when dissolved and a distinctive odor that affects the taste of the food in which it is used, and is specialized and expensive, making it difficult to put into practical use in terms of versatility and cost reduction. In addition, when the powder manufacturing method is characteristic, existing spray drying equipment suitable for mass production cannot be used, and new manufacturing equipment and manufacturing innovations are required, resulting in problems of high manufacturing costs.

一方、中鎖飽和脂肪酸トリグリセリドおよび/またはこれらの中鎖飽和脂肪酸トリグリセリドを主成分とした食用油脂と、澱粉加水分解物及び有機酸モノグリセリドを主成分としてなる粉末油脂組成物において、澱粉加水分解物のデキストロース当量が2~30であることを特徴とする粉末油脂組成物(特許文献8);脂溶性素材を油脂及び親油性乳化剤に分散した脂溶性素材分散油と、糖質を水及び親水性乳化剤に分散した糖質水分散液とを混合して油脂-糖質被覆分散液を作製し、任意に乾燥することにより油脂-糖質被覆分散液又は油脂-糖質粉末素材とすることを特徴とする油脂-糖質素材の製造方法において、糖質として、グルコース当量(DE)5~15の澱粉加水分解物を用いる製造方法(特許文献9);などが知られている。 On the other hand, there are known a powdered oil composition comprising edible oils and fats mainly composed of medium-chain saturated fatty acid triglycerides and/or medium-chain saturated fatty acid triglycerides, starch hydrolysates, and organic acid monoglycerides, the starch hydrolysates having a dextrose equivalent of 2 to 30 (Patent Document 8); a method for producing an oil-carbohydrate material, comprising mixing an oil-soluble material dispersion oil in which an oil-soluble material is dispersed in oils and fats and a lipophilic emulsifier with an aqueous carbohydrate dispersion in which a carbohydrate is dispersed in water and a hydrophilic emulsifier to produce an oil-carbohydrate coating dispersion, and optionally drying the oil-carbohydrate coating dispersion or an oil-carbohydrate powder material, in which a starch hydrolysate with a glucose equivalent (DE) of 5 to 15 is used as the carbohydrate (Patent Document 9); and the like.

ここで、デキストロース当量(=グルコース当量)とは、汎用的に使用される粉末化基材である澱粉加水分解物を分類するために、還元末端数によって求められる澱粉の分解度を示す指標である。しかしながら複雑な分子量分布を持つ澱粉加水分解物は、同じデキストロース当量であっても、含まれる分解物の分子量組成は異なることがあり、油脂および有機酸モノグリセリドのような低分子界面活性剤との相互作用を本質的に理解する上では、適切なパラメーターとはいえない。したがって汎用的な粉末化基材、噴霧乾燥という製造手法で、無タンパク粉末油脂組成物を作成するには、さらなる検討が必要であった。 Here, dextrose equivalent (= glucose equivalent) is an index showing the degree of starch decomposition determined by the number of reducing ends in order to classify starch hydrolysates, which are commonly used powdered base materials. However, starch hydrolysates have a complex molecular weight distribution, and even if they have the same dextrose equivalent, the molecular weight composition of the decomposition products contained therein may differ, and this cannot be said to be an appropriate parameter for fundamentally understanding the interactions with fats and oils and low molecular weight surfactants such as organic acid monoglycerides. Therefore, further investigation was required to create a protein-free powdered fat and oil composition using a commonly used powdered base material and the manufacturing method of spray drying.

本発明は、上記従来の実状に鑑みてなされたものであって、汎用的な粉末化基材を用いて、特に噴霧乾燥法に適し、かつ、長期間の乳化安定性に優れた飲料を提供可能な、粉末油脂組成物を提供することを課題とする。 The present invention was made in consideration of the above-mentioned conventional situation, and aims to provide a powdered oil composition that uses a general-purpose powdered base material, is particularly suitable for spray drying, and can provide a beverage with excellent long-term emulsion stability.

本発明者らが鋭意検討した結果、特定の澱粉加水分解物を使用することにより、上記課題を解決できることが分かり、本発明に到達した。 As a result of extensive research, the inventors discovered that the above problems could be solved by using a specific starch hydrolysate, and thus arrived at the present invention.

[澱粉加水分解物]
澱粉加水分解物とは、澱粉中のアミロースやアミロペクチン等の多糖類を、熱、酸、アルカリ、酵素等で加水分解したものの総称であり、デキストリンとも呼ばれ、グルコースがα-1,4または1,6結合で連なった多糖類が主成分である。
澱粉加水分解物としては、可溶性澱粉、薄手のり澱粉、アミロデキストリン、白色デキストリン、黄色デキストリン、ブリテシュガム、エリトロデキストリン、アクロデキストリン、マルトデキストリン等が挙げられる。これらは1種を単独で又は2種以上を組み合わせて用いることができる。
澱粉加水分解物の原料となる澱粉は、澱粉を含有する植物から採取される。この際、植物の品種としては、農産物として大量生産される品種が経済的に有利である。また、植物の品種により、澱粉中に含まれるアミロースとアミロペクチンの比率が異なる。アミロースはグルコースがα-1,4結合で直鎖状につながった構造を主としており、アミロペクチンはグルコースがα-1,6結合で分岐しながらつながった構造を主としている。一般的には、アミロースは低分子界面活性剤との相互作用が強いため、デキストリンのDE値が8より大のように加水分解度が高い場合には、澱粉の由来植物の品種に特に制限はないが、DEが8以下のように加水分解度が低い場合は、よりアミロペクチンの比率が高い澱粉を持つ由来植物が好ましく、そのような植物として、ワキシー種、すなわちワキシーコーンやもち米など、または、タピオカ、甘薯が好ましく、それらを1種類用いてもよいし、2種類以上を混合し、原料澱粉として用いてもよい。
[Starch hydrolysate]
Starch hydrolysate is a general term for products obtained by hydrolyzing polysaccharides in starch, such as amylose and amylopectin, with heat, acid, alkali, enzymes, etc., and is also called dextrin. Its main component is a polysaccharide in which glucose units are linked together through α-1,4 or 1,6 bonds.
Examples of starch hydrolysates include soluble starch, thin starch, amylodextrin, white dextrin, yellow dextrin, britesh gum, erythrodextrin, acrodextrin, maltodextrin, etc. These may be used alone or in combination of two or more.
Starch, which is the raw material of starch hydrolysates, is collected from a plant containing starch. In this case, it is economically advantageous to use a plant variety that is mass-produced as an agricultural product. The ratio of amylose and amylopectin contained in starch varies depending on the plant variety. Amylose mainly has a structure in which glucose is linearly linked by α-1,4 bonds, while amylopectin mainly has a structure in which glucose is branched and linked by α-1,6 bonds. Generally, since amylose has a strong interaction with a low molecular weight surfactant, there is no particular restriction on the variety of the plant from which the starch is derived when the degree of hydrolysis is high, such as when the DE value of dextrin is greater than 8, but when the degree of hydrolysis is low, such as when the DE is 8 or less, a plant having a starch with a higher ratio of amylopectin is preferred. As such a plant, waxy species, i.e., waxy corn, glutinous rice, tapioca, and sweet potato are preferred, and one of these may be used, or two or more of them may be mixed and used as the raw starch.

本発明で用いる澱粉加水分解物は、ゲル浸透クロマトグラフィー(GPC)で分子量分布を測定した際の総ピーク面積に対する、分子量8500以上18500以下の範囲のピーク面積の割合(以下、単に「ピーク面積割合」と称す場合がある。)が、15%以下であることを特徴とする。
このピーク面積の割合は、通常15%以下であり、中でも10%以下が好ましく、9%以下がより好ましく、7%以下がさらに好ましく、5%以下が特に好ましい。ピーク面積割合が上限以下であることにより、低分子界面活性剤との相互作用の影響が少なく、全体の乳化安定性が良好となる。ピーク面積割合は小さいほど好ましく、その下限については特に制限はない。
The starch hydrolysate used in the present invention is characterized in that the ratio of the peak area in the molecular weight range of 8,500 to 18,500 to the total peak area when the molecular weight distribution is measured by gel permeation chromatography (GPC) (hereinafter, sometimes simply referred to as the "peak area ratio") is 15% or less.
This peak area ratio is usually 15% or less, preferably 10% or less, more preferably 9% or less, even more preferably 7% or less, and particularly preferably 5% or less. By having the peak area ratio below the upper limit, the influence of the interaction with the low molecular weight surfactant is small, and the overall emulsion stability is good. The smaller the peak area ratio, the more preferable, and there is no particular restriction on the lower limit.

ここで、ゲル浸透クロマトグラフィーによる分子量分布の測定は、GPC装置を用いて通常、以下の条件で実施される。
カラム:TSKgelG2500PWXL、GMPWXL(東ソー(株)製)
カラム温度:40℃
移動相:0.2M 硝酸ナトリウム水溶液
流速:1.0ml/min
検出器:示差屈折率計
サンプル注入量:200μl
検量線:プルラン標準品(分子量2,350,000~5,900の間の9種類)、及びグルコース(分子量180)
また、ピーク面積割合は、上記の方法で求めた分子量分布の測定結果を、微分分子量分布曲線に変換した後、分子量8500以上18500以下に相当するピーク面積を合計し、総ピーク面積に対する割合として算出することができる。
Here, the measurement of the molecular weight distribution by gel permeation chromatography is usually carried out under the following conditions using a GPC apparatus.
Column: TSKgel G2500PWXL, GMPWXL (manufactured by Tosoh Corporation)
Column temperature: 40°C
Mobile phase: 0.2 M sodium nitrate aqueous solution Flow rate: 1.0 ml/min
Detector: differential refractometer Sample injection volume: 200 μl
Calibration curve: Pullulan standard (9 types with molecular weights between 2,350,000 and 5,900) and glucose (molecular weight 180)
In addition, the peak area ratio can be calculated by converting the measurement result of the molecular weight distribution obtained by the above method into a differential molecular weight distribution curve, adding up the peak areas corresponding to molecular weights of 8,500 or more and 18,500 or less, and expressing the ratio to the total peak area.

ピーク面積割合が15%以下である澱粉加水分解物は、例えば、逆浸透膜やナノろ過膜、限外ろ過膜、精密ろ過膜などを用いた膜分離や、シリカゲルやイオン交換樹脂を充填したカラムによる分画処理、α-アミラーゼやβ-アミラーゼ、グルコアミラーゼ等の澱粉分解酵素による低分子化処理等を併用することにより、澱粉加水分解物を分別精製して分子量8500以上18500以下の成分を除去することにより製造することができる。
また、ピーク面積割合が15%以下である澱粉加水分解物として、松谷化学工業社製「パインデックス#3」、「パインデックス#100」、日本食品化工社製「フジオリゴG67」、三和澱粉工業社製「サンデック#30」「サンデック#70」「サンデック#150」「サンデック#180」「サンデック#250」「サンデック#300」などが市販されており、これらを用いることができる。
A starch hydrolysate having a peak area ratio of 15% or less can be produced by, for example, separating and purifying the starch hydrolysate to remove components having a molecular weight of 8,500 or more and 18,500 or less using a combination of membrane separation using a reverse osmosis membrane, a nanofiltration membrane, an ultrafiltration membrane, a microfiltration membrane or the like, fractionation using a column packed with silica gel or an ion exchange resin, or low-molecular-weight treatment using a starch-degrading enzyme such as α-amylase, β-amylase, glucoamylase or the like.
In addition, examples of starch hydrolysates having a peak area ratio of 15% or less include "Pinex #3" and "Pinex #100" manufactured by Matsutani Chemical Industry Co., Ltd., "Fujioligo G67" manufactured by Nihon Shokuhin Kako Co., Ltd., and "Sandec #30", "Sandec #70", "Sandec #150", "Sandec #180", "Sandec #250", and "Sandec #300" manufactured by Sanwa Starch Co., Ltd., and these can be used.

組成物中の脂溶性物質の含有量が、上記下限以上の範囲であることにより、粉末組成物のコストあたりの脂溶性物質量が適切で経済的であり、上記上限以下の範囲であることにより、乳化安定化が良好で、粉末化の際や粉末組成物を溶解した際に乳化が壊れにくく、また、相対的に他の成分の含有量が適切となり、他の成分による機能を十分に得ることができる。 When the content of the fat-soluble substance in the composition is in the range above the lower limit, the amount of fat-soluble substance per unit cost of the powder composition is appropriate and economical, and when it is in the range below the upper limit, the emulsion is well stabilized and the emulsion is less likely to break during powdering or when the powder composition is dissolved, and the content of other components is relatively appropriate, allowing the functions of the other components to be fully obtained.

組成物中の澱粉加水分解物の含有量が、上記下限以上の範囲であることにより粉末化が良好となり、得られた粉末組成物は付着性が低く、流動性がよい、取扱いの良好な粉末となり、上記上限以下の範囲であることにより、粉末組成物のコストあたりの脂溶性物質量が適切で経済的であり、また、相対的に他の成分の含有量が適切となり、他の成分による機能を十分に得ることができる。 When the content of starch hydrolysate in the composition is in the range above the lower limit, powderization is good, and the resulting powder composition has low adhesion, good flowability, and is easy to handle. When the content is in the range below the upper limit, the amount of fat-soluble substance per cost of the powder composition is appropriate and economical, and the content of other components is relatively appropriate, allowing the functions of the other components to be fully obtained.

組成物中の低分子界面活性剤の含有量が、上記下限以上の範囲であることにより、乳化安定化が良好となり、粉末化の際や、粉末組成物を溶解した際に乳化が壊れにくく、上記上限以下の範囲であることにより、低分子界面活性剤自体の味が強くなることがなく、食品に用いた場合には風味を損ねにくい。また低分子界面活性剤は高価であるため、上記上限以下の範囲であることにより、粉末組成物自体の価格が適切となり経済的であり、また、相対的に他の成分の含有量が適切となり、他の成分による機能を十分に得ることができる。 By having the content of the low molecular weight surfactant in the composition be in the range above the lower limit, the emulsion is well stabilized and the emulsion is less likely to break down during powdering or when the powder composition is dissolved, and by having the content be below the upper limit, the taste of the low molecular weight surfactant itself is not strong and the flavor is less likely to be impaired when used in food. In addition, since low molecular weight surfactants are expensive, by having the content be below the upper limit, the price of the powder composition itself is appropriate and economical, and the content of other components is relatively appropriate, allowing the functions of the other components to be fully obtained.

また、脂溶性物質に対する澱粉加水分解物の含有割合が、上記下限以上の範囲であることにより粉末化が良好となり、得られた粉末組成物は付着性が低く、流動性がよい、取扱いの良好な粉末となり、上記上限以下の範囲であることにより、粉末組成物のコストあたりの脂溶性物質量が適切で経済的である。
低分子界面活性剤に対する澱粉加水分解物の含有割合が、上記下限以上の範囲であることにより、低分子界面活性剤自体の味が適切であり、食品に用いた場合には風味を損ねにくい。また、低分子界面活性剤は高価であるため、上記上限以下の範囲であることにより、粉末組成物自体の価格が適切となり経済的であり、乳化安定化も良好であり、粉末化の際や、粉末組成物を溶解した際に乳化が壊れにくい。
Furthermore, when the content ratio of the starch hydrolysate to the fat-soluble substance is in the range of not less than the above-mentioned lower limit, powderization is good, and the obtained powder composition has low adhesiveness, good flowability, and is easy to handle. When the content ratio is in the range of not more than the above-mentioned upper limit, the amount of fat-soluble substance per cost of the powder composition is appropriate, making it economical.
By setting the content ratio of the starch hydrolysate to the low molecular weight surfactant in the range of the above lower limit or more, the taste of the low molecular weight surfactant itself is appropriate, and the flavor is not easily impaired when used in food. In addition, since low molecular weight surfactants are expensive, by setting the content ratio in the range of the above upper limit or less, the price of the powder composition itself is appropriate and economical, the emulsion stabilization is also good, and the emulsion is not easily broken when powdering or dissolving the powder composition.

本発明の粉末組成物を製造する方法は特に制限はないが、好ましくは本発明の粉末組成物の製造方法に従って、ピーク面積割合が15%以下の澱粉加水分解物、脂溶性物質、低分子界面活性剤及び水を混合して混合液を調製し、この混合液を乳化して乳化液を得た後、得られた乳化液を噴霧乾燥、または凍結乾燥することにより製造される。
[Method of producing powder composition]
The method for producing the powder composition of the present invention is not particularly limited, but it is preferably produced according to the method for producing the powder composition of the present invention, by mixing a starch hydrolysate having a peak area ratio of 15% or less, a fat-soluble substance, a low molecular weight surfactant and water to prepare a mixed liquid, emulsifying this mixed liquid to obtain an emulsion, and then spray-drying or freeze-drying the obtained emulsion.

澱粉加水分解物、脂溶性物質、低分子界面活性剤及び水を混合して混合液を調製する際、水は、次工程で得られる乳化液の粘度及び固形分量が、後述の噴霧乾燥、または凍結乾燥に適した好適な粘度及び固形分量となるように用いることが好ましい。 When preparing a mixed liquid by mixing a starch hydrolysate, a fat-soluble substance, a low molecular weight surfactant, and water, it is preferable to use water so that the viscosity and solid content of the emulsion obtained in the next step are suitable for spray drying or freeze drying, as described below.

澱粉加水分解物、脂溶性物質、低分子界面活性剤及び水を混合して得られた混合液を乳化する方法としては、通常食品に用いられる均質乳化方法であれば特に制限なく採用することができ、例えば、ホモジナイザーを用いる方法や、コロイドミルを用いる方法、ホモミキサーを用いる方法などいずれも適用可能である。 The method for emulsifying the mixture obtained by mixing the starch hydrolysate, fat-soluble substance, low molecular weight surfactant, and water can be any homogeneous emulsification method normally used for food, without any particular restrictions. For example, any method using a homogenizer, a colloid mill, or a homomixer can be used.

乳化液の乾燥方法としては、噴霧乾燥法、気流乾燥法、ドラム乾燥法、円筒乾燥法、真空凍結乾燥法などの凍結乾燥法、真空乾燥法などを用いることができるが、大量生産に適した噴霧乾燥法が好ましい。
噴霧乾燥法により乳化液中の水分を除去して粉末組成物を製造する場合、必要に応じて乳化液を加熱してもよい。また、噴霧乾燥に供される乳化液は、噴霧時点の温度における粘度が5~200mPa・sであることが、乳化効率、乳化安定性及び噴霧乾燥工程における乳化液のノズルからの吐出性の点で好ましい。また、乳化液の固形分量は、噴霧乾燥時におけるノズルからの吐出性を確保するために、質量基準で5%以上が好ましく、10%以上がより好ましく、15%以上がさらに好ましく、70%以下が好ましく、60%以下がより好ましく、50%以下がさらに好ましい。
Methods for drying the emulsion that can be used include spray drying, flash drying, drum drying, cylinder drying, freeze drying such as vacuum freeze drying, and vacuum drying, but spray drying is preferred as it is suitable for mass production.
When the powder composition is produced by removing water from the emulsion by the spray drying method, the emulsion may be heated as necessary. In addition, the emulsion to be spray dried preferably has a viscosity of 5 to 200 mPa·s at the temperature at the time of spraying in terms of emulsification efficiency, emulsion stability, and the ability to eject the emulsion from a nozzle in the spray drying process. In addition, the solid content of the emulsion is preferably 5% or more, more preferably 10% or more, even more preferably 15% or more, and preferably 70% or less, more preferably 60% or less, and even more preferably 50% or less, based on mass, in order to ensure the ability to eject the emulsion from a nozzle during spray drying.

[飲料]
本発明の粉末組成物は、特に制限はないが、好ましくは飲食品に含有され、さらに好ましくは飲料に含有される。
[Beverages]
The powder composition of the present invention is not particularly limited, but is preferably contained in a food or drink, and more preferably in a beverage.

具体的には本発明の粉末組成物は、コーヒー飲料、紅茶飲料、紅茶以外の各種の茶飲料などの飲料に含有され、好ましくはミルクコーヒー、カフェオレ、ミルク紅茶などの乳飲料に使用される。乳飲料は、乳成分である乳脂肪、乳蛋白質等を含有する飲料である。 Specifically, the powder composition of the present invention is contained in beverages such as coffee beverages, black tea beverages, and various tea beverages other than black tea, and is preferably used in milk beverages such as milk coffee, cafe au lait, and milk black tea. Milk beverages are beverages that contain milk components such as milk fat and milk protein.

本発明の粉末組成物を含む飲料は、例えば次のようにして製造される。まず、本発明の粉末組成物、乳成分、コーヒー、紅茶または茶抽出物、乳化剤、必要に応じて水などを混合して混合液を調製する。この混合液には、この他、砂糖、香料、ビタミン、重曹などのpH調整剤、甘味料、増粘安定剤、酸化防止剤、酵素などの公知の配合剤を加えてもよい。油分は粉末組成物として添加されるので、乳成分としては脱脂粉乳、脱脂濃縮乳、WPC、WPI、MPC、TMP、バターミルクパウダー、乳糖、乳清ミネラルなどの乳蛋白質や乳糖、乳由来のミネラルなどの無脂乳固形分を含有する原料を用いることが好ましい。ただし、必要に応じて、牛乳、濃縮乳、全脂粉乳、フレッシュクリーム、チーズ等の乳成分、バターやバターオイル等の乳脂を加えてもよい。 A beverage containing the powder composition of the present invention is produced, for example, as follows. First, a mixture is prepared by mixing the powder composition of the present invention, milk components, coffee, black tea or tea extract, an emulsifier, and water, if necessary. This mixture may also contain known compounding agents such as sugar, flavorings, vitamins, pH adjusters such as baking soda, sweeteners, thickening stabilizers, antioxidants, and enzymes. Since the oil is added as a powder composition, it is preferable to use raw materials containing non-fat milk solids such as milk proteins such as skim milk powder, skim concentrated milk, WPC, WPI, MPC, TMP, buttermilk powder, lactose, and whey minerals, as well as milk-derived minerals. However, milk components such as milk, concentrated milk, whole milk powder, fresh cream, and cheese, and milk fats such as butter and butter oil may be added as necessary.

次いで、得られた混合液を撹拌して乳化する。乳化方法としては、通常食品に用いられる均質乳化方法であれば特に制限なく使用することができ、例えば、ホモジナイザーを用いる方法や、コロイドミルを用いる方法、ホモミキサーを用いる方法などいずれも用いることができる。この均質乳化処理は、通常40~80℃の加温条件下で行われ、ホモジナイザーを用いた乳化工程は、通常5~200MPa、好ましくは10~100MPaの高圧条件で行なわれる。 The resulting mixture is then stirred to emulsify. Any homogeneous emulsification method typically used for food products can be used without particular limitations, and any method using a homogenizer, a colloid mill, or a homomixer can be used. This homogeneous emulsification process is typically carried out under heated conditions of 40 to 80°C, and the emulsification step using a homogenizer is typically carried out under high pressure conditions of 5 to 200 MPa, preferably 10 to 100 MPa.

この均質乳化処理後には、UHT殺菌、レトルト殺菌などの殺菌処理を行う。通常レトルト殺菌は、121℃、20~40分の条件で行われる。一方、PETボトル用飲料などに用いられるUHT殺菌は、より高温、例えば殺菌温度130~150℃で、且つ121℃での殺菌価(Fo)が10~50に相当する超高温殺菌である。UHT殺菌は飲料に直接水蒸気を吹き込むスチームインジェクション式や飲料を水蒸気中に噴射して加熱するスチームインフュージョン式などの直接加熱方式、プレートやチューブなど表面熱交換器を用いる間接加熱方式など公知の方法で行うことができ、例えばプレート式殺菌装置を用いることができる。
尚、製造された本発明の飲料は、容器詰め飲料に好適であり、例えば、缶飲料、ペットボトル飲料として用いられることができる。
After this homogeneous emulsification treatment, a sterilization treatment such as UHT sterilization or retort sterilization is performed. Retort sterilization is usually performed under conditions of 121°C and 20 to 40 minutes. On the other hand, UHT sterilization used for beverages in PET bottles is an ultra-high temperature sterilization at a higher temperature, for example, a sterilization temperature of 130 to 150°C, and a sterilization value (Fo) at 121°C corresponds to 10 to 50. UHT sterilization can be performed by a known method such as a direct heating method such as a steam injection type in which steam is directly blown into a beverage or a steam infusion type in which a beverage is heated by injecting it into steam, or an indirect heating method using a surface heat exchanger such as a plate or tube, and for example, a plate-type sterilization device can be used.
The produced beverage of the present invention is suitable for use as a packaged beverage, and can be used, for example, as a canned beverage or a PET bottle beverage.

このようにして製造される本発明の飲料中の本発明の粉末組成物の含有量は、同時に添加される乳成分、コーヒー、紅茶または茶抽出物の量によって異なるが、通常0.1質量%以上であることが好ましく、0.5質量%以上であることがより好ましく、1.0質量%以上であることがさらに好ましく、30質量%以下であることが好ましく、20質量%以下であることがより好ましく、10質量%以下であることがさらに好ましい。
また、乳成分を含む乳飲料の場合、乳飲料中の乳成分の含有量は、牛乳換算で5質量%以上であることが好ましく、10質量%以上であることがより好ましく、60質量%以下であることが好ましく、40質量%以下であることが、より好ましく、25質量%以下であることがさらに好ましい。
The content of the powder composition of the present invention in the beverage of the present invention produced in this manner will vary depending on the amount of milk components, coffee, black tea or tea extract added at the same time, but is usually preferably 0.1 mass% or more, more preferably 0.5 mass% or more, even more preferably 1.0 mass% or more, preferably 30 mass% or less, more preferably 20 mass% or less, and even more preferably 10 mass% or less.
Furthermore, in the case of a milk beverage containing milk components, the content of the milk components in the milk beverage is preferably 5% by mass or more, and more preferably 10% by mass or more, calculated as milk, and is preferably 60% by mass or less, more preferably 40% by mass or less, and even more preferably 25% by mass or less.

乳飲料中の乳成分と本発明の粉末組成物の含有割合は、乳成分:粉末組成物(質量比)=1:0.01~100であることが好ましい。この範囲よりも粉末組成物が少ないと乳化安定性への寄与がなく、粉末組成物の効果を発揮することが困難であり、多いと充分な乳の風味が得られないため、乳飲料として不適である。 The content ratio of the milk components in the milk beverage to the powder composition of the present invention is preferably milk components:powder composition (mass ratio) = 1:0.01 to 100. If the powder composition is less than this range, it will not contribute to emulsion stability and it will be difficult to exert the effects of the powder composition, and if it is more than this range, it will not have a sufficient milk flavor and will be unsuitable as a milk beverage.

飲料に乳化剤を添加する場合、乳化剤としては、食品に使用可能な乳化剤であれば特に制限はなく使用することができる。例示するならば、ショ糖脂肪酸エステル、ポリソルベート(ポリオキシエチレンソルビタン酸エステル)、グリセリン脂肪酸エステル(モノグリセリド、有機酸モノグリセリド、ポリグリセリン脂肪酸エステル)、ソルビタン脂肪酸エステル、プロピレングリコール脂肪酸エステル、などの脂肪酸エステル類、ステアロイル乳酸ナトリウム、ステアロイル乳酸カルシウム、酵素分解レシチン、レシチン、サポニンなどが挙げられる。これらの中では、ショ糖脂肪酸エステル、有機酸モノグリセリド、ポリグリセリン脂肪酸エステル、ソルビタン脂肪酸エステル、ポリソルベート(ポリオキシエチレンソルビタン酸エステル)が好ましく、ショ糖脂肪酸エステル、有機酸モノグリセリド、ポリグリセリン脂肪酸エステルが、乳飲料の乳化安定性がよいため更に好ましい。 When an emulsifier is added to a beverage, any emulsifier that can be used in food can be used without any particular restrictions. Examples include fatty acid esters such as sucrose fatty acid esters, polysorbates (polyoxyethylene sorbitan acid esters), glycerin fatty acid esters (monoglycerides, organic acid monoglycerides, polyglycerin fatty acid esters), sorbitan fatty acid esters, propylene glycol fatty acid esters, sodium stearoyl lactate, calcium stearoyl lactate, enzymatically decomposed lecithin, lecithin, and saponin. Among these, sucrose fatty acid esters, organic acid monoglycerides, polyglycerin fatty acid esters, sorbitan fatty acid esters, and polysorbates (polyoxyethylene sorbitan acid esters) are preferred, and sucrose fatty acid esters, organic acid monoglycerides, and polyglycerin fatty acid esters are even more preferred because of their good emulsion stability in milk beverages.

また、上記乳化剤において、飲料における危害菌である耐熱性菌に対して効果を持つ食品用乳化剤(すなわち、静菌性乳化剤)を単独、または併用して用いることもできる。耐熱性菌に対して効果を持つ食品用乳化剤としては、その効果を有する食品用乳化剤であれば、特に制限なく使用することができるが、ショ糖脂肪酸エステル、ポリグリセリン脂肪酸エステル、有機酸モノグリセリドが好ましく、特に構成する脂肪酸の炭素数が14~22のショ糖脂肪酸エステル、ポリグリセリン脂肪酸エステル、有機酸モノグリセリドがより好ましく、構成する脂肪酸の炭素数が16~18のショ糖脂肪酸エステル、ポリグリセリン脂肪酸エステルがさらに好ましく、これらは菌に対する有効性が高いため好適である。使用するショ糖脂肪酸エステル、ポリグリセリン脂肪酸エステルとしては、モノエステル含量が50質量%以上、好ましくは60質量%以上、さらに好ましくは70質量%以上であることが、菌に対する有効性が高いため好適である。ポリグリセリン脂肪酸エステルとしては、ポリグリセリンの平均重合度が2~5であることが好ましく、さらに2~3であることが、菌に対する有効性が高いため最も好ましい。 In addition, in the above emulsifier, food emulsifiers (i.e., bacteriostatic emulsifiers) that are effective against heat-resistant bacteria, which are harmful bacteria in beverages, can be used alone or in combination. As food emulsifiers that are effective against heat-resistant bacteria, any food emulsifier that has that effect can be used without particular restrictions, but sucrose fatty acid esters, polyglycerin fatty acid esters, and organic acid monoglycerides are preferred, and sucrose fatty acid esters, polyglycerin fatty acid esters, and organic acid monoglycerides in which the constituent fatty acids have 14 to 22 carbon atoms are more preferred, and sucrose fatty acid esters and polyglycerin fatty acid esters in which the constituent fatty acids have 16 to 18 carbon atoms are even more preferred, and these are suitable because they are highly effective against bacteria. As the sucrose fatty acid esters and polyglycerin fatty acid esters to be used, those with a monoester content of 50% by mass or more, preferably 60% by mass or more, and more preferably 70% by mass or more are suitable because they are highly effective against bacteria. For polyglycerol fatty acid esters, the average degree of polymerization of polyglycerol is preferably 2 to 5, and most preferably 2 to 3, as this is more effective against bacteria.

乳化剤の乳飲料における含有量は、通常0.005質量%以上が好ましく、0.01質量%以上がより好ましく、0.5質量%以下が好ましく、0.3質量%以下がより好ましい。 The content of emulsifier in a milk beverage is generally preferably 0.005% by mass or more, more preferably 0.01% by mass or more, and preferably 0.5% by mass or less, more preferably 0.3% by mass or less.

このようにして得られる本発明の粉末組成物を含有する飲料は、特に乳化安定性の点から、実質的にカゼインナトリウムを含有せず、静菌性乳化剤を含有する飲料であることが好ましい。すなわち、粉末組成物中に実質的にカゼインナトリウムを含有させないことが好ましく、さらには、飲料の製造においてもカゼインナトリウムを実質的に含有させないことが好ましい。尚、実質的に含有しないとは、組成物中または飲料中において、カゼインナトリウムの含有量が0.3質量%以下、好ましくは0.1質量%以下、より好ましくは0.05質量%以下、さらに好ましくは0.01質量%以下、特に好ましくは0.001質量%以下であることを意味する。最も好ましくは全く含有しないことである。
本発明の粉末組成物を含有する飲料は、静菌性を有しながらも、高い乳化安定性を有する飲料である。
The beverage containing the powder composition of the present invention thus obtained is preferably a beverage that does not substantially contain sodium caseinate and contains a bacteriostatic emulsifier, particularly from the viewpoint of emulsion stability. That is, it is preferable that the powder composition does not substantially contain sodium caseinate, and furthermore, it is preferable that the beverage is also produced without substantially containing sodium caseinate. Incidentally, "substantially not containing" means that the content of sodium caseinate in the composition or beverage is 0.3% by mass or less, preferably 0.1% by mass or less, more preferably 0.05% by mass or less, even more preferably 0.01% by mass or less, and particularly preferably 0.001% by mass or less. Most preferably, it is completely not contained.
A beverage containing the powder composition of the present invention has bacteriostatic properties and high emulsion stability.

[試験例3]
試験例1、2の結果から、いずれの粉末組成物も、粉末組成物を得る時点では差異はなく、水に粉末組成物を分散、溶解したエマルションで差異がみられたことから、保存後のエマルションの粒子径増加率が、粉末組成物を再度溶解した際の乳化安定性を反映していると考えられた。そのため、澱粉加水分解物を含有する乳化液を調製し、それを粉末化せず、試験例1、2と同濃度に水で希釈し、その希釈エマルションの粒子径増加率を確認した。
[Test Example 3]
From the results of Test Examples 1 and 2, there was no difference between the powder compositions at the time of obtaining the powder compositions, but differences were observed in the emulsions obtained by dispersing and dissolving the powder compositions in water, and therefore it was considered that the particle size increase rate of the emulsion after storage reflects the emulsion stability when the powder composition is dissolved again. Therefore, an emulsion containing a starch hydrolysate was prepared, and without powdering it, it was diluted with water to the same concentration as in Test Examples 1 and 2, and the particle size increase rate of the diluted emulsion was confirmed.

具体的には、硬化ヤシ油(「硬化ヤシ油」不二製油社製)20質量%、ショ糖脂肪酸エステル(ショ糖ステアリン酸エステル「リョートー(登録商標)シュガーエステルS-570」三菱化学フーズ社製、HLB5)2.5質量%、澱粉加水分解物D~I(三和澱粉工業社製、サンデックシリーズ、詳細を表5に示す)27.5質量%および水50質量%を混合した。この混合液を65℃でホモミキサーを用いて分散させた後、高圧乳化機を用いて乳化し、得られた乳化液のうち2.2gを100mlの水に分散した希釈乳化液を調製した。残りの乳化液は、噴霧乾燥機で乾燥して、各々、澱粉加水分解物の異なる粉末組成物を得た。各々を粉末組成物D~Iとする。 Specifically, 20% by mass of hydrogenated coconut oil ("Hydrogenated coconut oil" manufactured by Fuji Oil Co., Ltd.), 2.5% by mass of sucrose fatty acid ester (sucrose stearate ester "Ryoto (registered trademark) Sugar Ester S-570" manufactured by Mitsubishi Chemical Foods Corporation, HLB 5), 27.5% by mass of starch hydrolysates D to I (manufactured by Sanwa Starch Industry Co., Ltd., Sandeck series, details are shown in Table 5), and 50% by mass of water were mixed. This mixture was dispersed at 65°C using a homomixer, and then emulsified using a high-pressure emulsifier. 2.2 g of the resulting emulsion was dispersed in 100 ml of water to prepare a diluted emulsion. The remaining emulsion was dried using a spray dryer to obtain powder compositions each containing a different starch hydrolysate. These are designated powder compositions D to I.

得られた希釈乳化液を、25℃、35℃、40℃、55℃で1週間(1W)、および2週間(2W)保存したときの希釈乳化液の粒子のメジアン径増加率を以下の基準で評価した。メジアン径は、レーザ回折/散乱式粒子径分布測定装置(堀場製作所社製、LA-950V2)を用いて測定した。結果を表6に示す。 The resulting diluted emulsion was stored at 25°C, 35°C, 40°C, and 55°C for one week (1W) and two weeks (2W), and the increase in median diameter of the particles in the diluted emulsion was evaluated according to the following criteria. The median diameter was measured using a laser diffraction/scattering type particle size distribution measuring device (LA-950V2, manufactured by Horiba, Ltd.). The results are shown in Table 6.
