Description

【0001】
【産業上の利用分野】本発明は、カルシウムを強化した豆乳飲料の製造方法に関し、更に詳しくは、通常、豆乳にカルシウムを添加した際に生じる蛋白質の凝集物の生成を防止するカルシウム強化豆乳飲料の製造方法に関する。
【0002】
【従来の技術】近年、食品に対する健康志向の増加から、大豆を主原料としてた食品が取り上げられることが多い。特に豆乳は、大豆を水に浸漬後すりつぶし、加熱、濾過して得られる乳状の飲料であり、大豆には良質の蛋白質をはじめ、イソフラボン、レシチン、サポニン、リノール酸などの有用成分が含まれており、生活習慣病や骨粗鬆症を防ぐ効果を有することが判明してきていることから需要が高まっている。
【0003】
従来より、豆乳を安定に供給するため、豆乳のおり防止方法として、大豆磨砕抽出液にカルシウムイオン15〜28mg%を攪拌しながら徐々に添加する方法が開示されている(特許文献1)。
【0004】
最近では、係る豆乳に様々な成分、特にカルシウムを添加し、より健康食品としての価値を高めるべく様々な検討がなされている。しかしながら、上記豆乳飲料のようにカルシウムを強化する目的でカルシウムを添加すると、カルシウムイオンの蛋白質凝固作用によって豆乳が凝固するため、特許文献1のように、豆乳へのカルシウムの添加に時間を要したり、カルシウムの添加量を減らす必要があるといった問題が生じていた。また、カルシウムイオンを豆乳へ30mg以上添加すると蛋白質の凝集が生じるため、それ以上のカルシウムを添加することができなかった(特許文献2)と開示されている。
【0005】
係る問題を解決するために様々な方法が検討され、カルシウムイオンの含量が、牛乳と同程度の100mg程度まで添加できる技術が開示されている。例えば、豆乳にリンゴ酸カルシウムを添加してカルシウム分を強化する方法(特許文献2)、豆乳にグリセリンまたはプロピレングリコールの存在下、カルシウム化合物を添加する方法(特許文献4)、カルシウム、糖類、安定剤を大豆蛋白質抽出液に添加した後、この溶液に酸味料を加えた酸性豆乳飲料(特許文献4)、豆乳のカルシウム成分富化に際し、カルシウムと特定のナトリウム塩を併用する方法(特許文献5)が開示されている。

【特許文献4】特開昭58−13358号公報
【特許文献5】特開昭60−87752号公報
【0007】
【発明が解決しようとする課題】
しかしながら、特許文献5に記載された方法を本発明者らが実施したところ、豆乳にカルシウムをそのまま添加する方法では、カルシウムイオンが豆乳中の蛋白質と反応し、カルシウム凝固物が生成する実験結果が得られた。上記のような従来技術・製造方法では、カルシウムと蛋白質の反応による凝集を完全に防ぐことが困難であった。
【0008】
【課題を解決するための手段】
そこで、本発明者らは、カルシウムを添加した際の凝集物の生成を防止するために、鋭意研究した結果、カルシウムとクエン酸塩を予め水に溶解した状態で豆乳と混合して攪拌処理すれば、カルシウムによる蛋白質の凝集物が生成しないとの知見を得た。本発明は係る知見に基づくものである。
【0009】
本発明は、豆乳本来のpHである中性域に保ったまま、カルシウムを強化した豆乳飲料の製造方法を提供するものであり、カルシウム及びクエン酸塩を水に溶解し、溶液状態で豆乳とを混合することを特徴とする。
【0010】
カルシウムとクエン酸塩を水に溶解する方法として、カルシウム及びクエン酸塩を一溶液中に溶解しても、二液にそれぞれ別に溶解しても良く、カルシウム及びクエン酸塩が水に溶解した状態となっていれば良い。また、水に溶解する方法であるが、常温の水でも良いが、40〜95℃程度のお湯に溶解し、5〜20分程度の加熱攪拌溶解を行うのが好ましい。
【0011】
次に、予め水に溶解したカルシウムとクエン酸塩と豆乳を混合する。混合する際、攪拌混合しながら行うのが好ましいが、係る攪拌の速度、手段については特に制限されず、公知の方法を採用することができる。更には、具体的には、一般に利用されている攪拌機、乳化機(ホモゲナイザー)等も利用することができる。好ましくは、攪拌効率、作業時間等の面からホモゲナイザーを利用するのがよい。その他の製造方法は、常法通り行うことができ、容器充填後、加熱殺菌を行い豆乳飲料を得るものである。また、容器充填後の加熱殺菌処理も、通常の殺菌条件であれば制限無く利用できる。具体的には、加温殺菌、プレート殺菌、レトルト殺菌、オートクレーブ殺菌等の処理を行えばよい。
【0012】
尚、本発明に係るカルシウム強化豆乳飲料の容器としては、従来より利用されているものを制限無く利用することができる。具体的には、紙パック、ペットボトル、缶、瓶等である。
【0013】
本発明では、上述に掲げる事項以外は、従来の豆乳の製造方法に従い製造することが可能であるので、新規な製造設備を施設することなく本発明によるカルシウム強化豆乳飲料を製造することができる。
【0014】
本発明でいう豆乳とは、大豆を水に浸漬後すりつぶし、加熱、濾過して得られる乳状の飲料であり、日本農林規格(JAS)により次のような規格により分類されているが、本発明で用いる豆乳は、これらの何れであってもよく、液状、粉末状等のものなどを使用することができる。

調製豆乳:大豆固形分6%以上
豆乳飲料:イ、果汁入り 大豆固形分2%以上
ロ、その他 大豆固形分4%以上
大豆蛋白飲料:大豆蛋白50%以下の使用の豆乳飲料
【0016】
本発明でカルシウム強化のために添加するカルシウムは、カルシウム、カルシウムイオン、カルシウム塩の何れであってもよく、水溶性のものであれば特に制限無く利用できる。具体的には、有機酸塩或いは無機酸塩の何れでもよく、例えば、乳酸カルシウム、グルコン酸カルシウム、フマル酸カルシウム、クエン酸カルシウム、コハク酸カルシウム、酢酸カルシウム等の有機酸塩、塩化カルシウム等の無機酸塩を好ましくあげることができ、これらより1種又は2種以上を選択して使用することが出来る。好ましくは乳酸カルシウムである。
【0017】
本発明におけるクエン酸塩としては、カリウム塩、ナトリウム塩等が例示され、好ましくはクエン酸ナトリウムである。クエン酸塩の添加量は、豆乳飲料のpHを変動させることが目的ではないため、具体的にはクエン酸ナトリウムの場合、豆乳に対して0.8〜2.5重量%の範囲が例示できる。従来の技術に於いても有機酸を酸味料として添加する技術(特許文献3)が開示されているが、係る有機酸の使用は、豆乳飲料の液性を酸性にするために添加されるものであり、本発明とはその目的が異なり、添加量も全く異なる範囲である。また、本発明ではクエン酸塩を添加することから、豆乳飲料のpHに与える影響はほとんどなく、この点でも従来とは異なる技術である。
【0018】
本発明に係る豆乳飲料のpHは6〜7.5がよく、好ましくは6.5〜7である。pHが6より酸性側になると、含有されている蛋白質の凝集が生じ好ましくない。また、pHが高くなると蛋白質が溶解するので好ましくない。
【0019】
本発明は、豆乳本来の液性を保持したまま、蛋白質の凝集を生じないカルシウム強化豆乳飲料を提供するものである。本発明のカルシウム強化豆乳飲料には、必要に応じて、糖類、甘味料、高甘味度甘味料、酸味料、調味料、色素、香料、果汁、ピューレ、保存料、エキス、pH調整剤、糊料、洋酒、ビタミン、その他ミネラル類、ゼリービーズや数mm角にカットした果実、柑橘系果実のさのう等も、本発明の効果を損なわない範囲で任意に添加することができる。
【0020】
糖類としては、砂糖、果糖、ブドウ糖、水飴、還元水飴、はちみつ、異性化糖、転化糖、オリゴ糖(イソマルトオリゴ糖、還元キシロオリゴ糖、還元ゲンチオオリゴ糖、キシロオリゴ糖、ゲンチオオリゴ糖、ニゲロオリゴ糖、テアンデオリゴ糖、大豆オリゴ糖等)、トレハロース、糖アルコール(マルチトール、エリスリトール、ソルビトール、パラチニット、キシリトール、ラクチトール等)、砂糖結合水飴(カップリングシュガー)などを挙げることができる。
【0021】
また、従来公知若しくは将来知られうる甘味成分も糖類の代わりに用いることができる。具体的には、アスパルテーム、アセスルファムカリウム、スクラロース、アリテーム、ネオテーム、カンゾウ抽出物(グリチルリチン)、サッカリン、サッカリンナトリウム、ステビア抽出物、ステビア末などの甘味成分を用いても良い。
【0022】
さらに、本発明で使用する豆乳には、不溶性の蛋白質や油成分が含まれている。これら豆乳由来の成分が静置することにより、或いは殺菌処理により沈殿或いは浮遊物として発現する場合が考えられるので、カルシウム強化豆乳飲料中に分散安定効果を有する乳化安定剤等を添加することができる。ここで使用する乳化安定剤等は、乳化効果、分散安定効果を有するものであれば制限無く使用できる。具体的には、モノグリセリン脂肪酸エステル、ジグリセリン脂肪酸エステル、ポリグリセリン脂肪酸エステル、ショ糖脂肪酸エステル、コハク酸モノグリセライド、クエン酸モノグリセライド、酢酸モノグリセライド、ジアセチル酒石酸モノグリセライド等の有機酸モノグリセライド、プロピレングリコール脂肪酸エステル、レシチン、酵素処理レシチン等の乳化剤;大豆多糖類、ペクチン、カラギーナン、キサンタンガム、アラビアガム、微結晶セルロース、水溶性ヘミセルロース、カルボキシメチルセルロース、カルボキシメチルセルロースナトリウム等のゲル化剤等が挙げられ、これらの1種以上を使用することができる。
【0023】
本発明により、カルシウムの添加量が増量されたにもかかわらず、豆乳本来の液性である中性域にpHを保ち、蛋白質の凝集が生じないカルシウム強化豆乳飲料を提供することが可能となった。本発明によれば、牛乳に含まれるカルシウム量(100mg%)を超える150mg%程度まで添加することが可能である。さらにクエン酸塩の添加量を調整することで、さらなる増量をはかることが可能となる。

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a soymilk beverage with enhanced calcium, and more particularly, to a calcium-enriched soymilk beverage which normally prevents the formation of protein aggregates when calcium is added to soymilk. And a method for producing the same.
[0002]
2. Description of the Related Art In recent years, foods using soybeans as a main raw material are often taken up due to an increase in health consciousness of foods. In particular, soy milk is a milky drink obtained by immersing soybeans in water, then grinding, heating and filtering.Soybeans contain useful ingredients such as isoflavones, lecithin, saponin, and linoleic acid, as well as high-quality proteins. In addition, demand has been increasing because it has been found to be effective in preventing lifestyle-related diseases and osteoporosis.
[0003]
Conventionally, in order to stably supply soy milk, a method of gradually adding 15 to 28 mg% of calcium ions to a ground soybean extract with stirring has been disclosed as a method for preventing soy milk from spilling (Patent Document 1).
[0004]
Recently, various studies have been made to add various components, particularly calcium, to such soymilk to enhance its value as a health food. However, when calcium is added for the purpose of strengthening calcium as in the above-mentioned soy milk drink, soy milk coagulates due to the protein coagulation action of calcium ions, and as described in Patent Document 1, it takes time to add calcium to soy milk. And it is necessary to reduce the amount of calcium added. Further, it is disclosed that when 30 mg or more of calcium ion is added to soymilk, protein aggregation occurs, and thus no more calcium can be added (Patent Document 2).
[0005]
Various methods have been studied to solve this problem, and a technique has been disclosed in which the content of calcium ions can be added up to about 100 mg, which is about the same as milk. For example, a method of adding calcium malate to soy milk to enhance the calcium content (Patent Document 2), a method of adding a calcium compound to soy milk in the presence of glycerin or propylene glycol (Patent Document 4), calcium, saccharides, Soybean protein drink, after adding the agent to the soybean protein extract, acidified soybean milk beverage (Patent Document 4), and a method using calcium and a specific sodium salt in combination for enriching the calcium component of soymilk (Patent Document 5) ) Is disclosed.

[Problems to be solved by the invention]
However, when the present inventors carried out the method described in Patent Document 5, in the method of adding calcium to soy milk as it is, the result of an experiment in which calcium ions react with proteins in soy milk to generate calcium coagulated products was found. Obtained. With the above-described conventional techniques and manufacturing methods, it was difficult to completely prevent aggregation due to the reaction between calcium and protein.
[0008]
[Means for Solving the Problems]
Therefore, the present inventors have conducted intensive studies in order to prevent the formation of aggregates when calcium is added. As a result, calcium and citrate are mixed with soymilk in a state of being dissolved in water in advance and stirred. For example, it was found that calcium did not produce protein aggregates. The present invention is based on such findings.
[0009]
The present invention provides a method for producing a soymilk beverage with enhanced calcium while maintaining the pH in the neutral range, which is the original pH of soymilk, by dissolving calcium and citrate in water, and adding soymilk in solution. Is mixed.
[0010]
As a method for dissolving calcium and citrate in water, calcium and citrate may be dissolved in one solution or separately in two solutions, and calcium and citrate are dissolved in water. It should just be. The method of dissolving in water may be water at room temperature, but it is preferable to dissolve in hot water of about 40 to 95 ° C. and perform heating and stirring for about 5 to 20 minutes.
[0011]
Next, calcium, citrate and soymilk previously dissolved in water are mixed. The mixing is preferably performed with stirring and mixing, but the stirring speed and means are not particularly limited, and a known method can be employed. Furthermore, specifically, generally used stirrers, emulsifiers (homogenizers) and the like can also be used. Preferably, a homogenizer is used in terms of stirring efficiency, working time, and the like. Other production methods can be carried out as usual, and after filling the container, heat sterilization is performed to obtain a soymilk beverage. In addition, the heat sterilization treatment after filling the container can be used without limitation under normal sterilization conditions. Specifically, treatments such as heating sterilization, plate sterilization, retort sterilization, and autoclave sterilization may be performed.
[0012]
As the container of the calcium-enriched soymilk beverage according to the present invention, those conventionally used can be used without limitation. Specifically, it is a paper pack, a plastic bottle, a can, a bottle, or the like.
[0013]
In the present invention, since it is possible to produce according to a conventional method for producing soymilk except for the matters listed above, the calcium-enriched soymilk beverage according to the present invention can be produced without installing a new production facility.
[0014]
The soy milk as referred to in the present invention is a milky beverage obtained by immersing soybeans in water, crushing, heating and filtering, and is classified according to the following standards according to the Japanese Agricultural Standards (JAS). The soymilk used in the above may be any of these, and a liquid or powdery one may be used.
[0015]
Soy milk: 8% or more soy solids Prepared soy milk: 6% or more soy milk solids Beverage: A, with fruit juice Soy solids 2% or more B Others Soy solids 4% or more Soy protein drink: Use of 50% or less soy protein Soy milk drink
In the present invention, calcium added for enhancing calcium may be any of calcium, calcium ion, and calcium salt, and any water-soluble calcium can be used without any particular limitation. Specifically, any of an organic acid salt or an inorganic acid salt may be used. For example, organic acid salts such as calcium lactate, calcium gluconate, calcium fumarate, calcium citrate, calcium succinate, calcium acetate, calcium chloride, etc. Inorganic acid salts are preferred, and one or two or more of them can be selected and used. Preferably it is calcium lactate.
[0017]
Examples of the citrate in the present invention include potassium salts and sodium salts, and preferably sodium citrate. Since the purpose of adding the citrate is not to change the pH of the soymilk beverage, specifically, in the case of sodium citrate, the range of 0.8 to 2.5% by weight based on the soymilk can be exemplified. . In the prior art, a technique of adding an organic acid as an acidulant is disclosed (Patent Document 3), but the use of such an organic acid is added to make the liquidity of a soy milk beverage acidic. The purpose of the present invention is different from that of the present invention, and the amount of addition is within a completely different range. Further, in the present invention, since the citrate is added, there is almost no effect on the pH of the soymilk beverage, and this is a technique different from the conventional technique also in this respect.
[0018]
The pH of the soymilk beverage according to the present invention is preferably from 6 to 7.5, and more preferably from 6.5 to 7. If the pH is more acidic than 6, the protein contained therein is undesirably aggregated. Also, if the pH is too high, the protein is dissolved, which is not preferable.
[0019]
The present invention provides a calcium-enriched soymilk beverage that does not cause protein aggregation while maintaining the original liquid properties of soymilk. The calcium-enriched soy milk beverage of the present invention may contain, as necessary, sugars, sweeteners, high-intensity sweeteners, acidulants, seasonings, pigments, flavors, fruit juices, purees, preservatives, extracts, pH adjusters, and pastes. Ingredients, Western liquors, vitamins, other minerals, jelly beads, fruits cut into several mm squares, citrus fruits, and the like can be arbitrarily added as long as the effects of the present invention are not impaired.
[0020]
Examples of the saccharides include sugar, fructose, glucose, syrup, reduced syrup, honey, isomerized sugar, invert sugar, oligosaccharide (isomaltooligosaccharide, reduced xylo-oligosaccharide, reduced gentio-oligosaccharide, xylo-oligosaccharide, gentio-oligosaccharide, nigerooligosaccharide, andanderoligosaccharide) And soybean oligosaccharides), trehalose, sugar alcohols (maltitol, erythritol, sorbitol, palatinit, xylitol, lactitol, etc.), sugar-bound starch syrup (coupling sugar) and the like.
[0021]
In addition, conventionally known or future known sweet components can be used in place of the saccharide. Specifically, sweet components such as aspartame, acesulfame potassium, sucralose, alitame, neotame, licorice extract (glycyrrhizin), saccharin, saccharin sodium, stevia extract, and stevia powder may be used.
[0022]
Furthermore, the soymilk used in the present invention contains insoluble proteins and oil components. It is conceivable that these soy milk-derived components are allowed to stand or appear as precipitates or suspended matter by a sterilization treatment. Therefore, an emulsion stabilizer having a dispersion stabilizing effect can be added to the calcium-enriched soy milk beverage. . The emulsion stabilizer and the like used here can be used without limitation as long as they have an emulsifying effect and a dispersion stabilizing effect. Specifically, monoglycerin fatty acid ester, diglycerin fatty acid ester, polyglycerin fatty acid ester, sucrose fatty acid ester, succinic acid monoglyceride, citrate monoglyceride, acetic acid monoglyceride, organic acid monoglyceride such as diacetyltartaric acid monoglyceride, propylene glycol fatty acid ester, Emulsifiers such as lecithin and enzyme-treated lecithin; gelling agents such as soybean polysaccharide, pectin, carrageenan, xanthan gum, gum arabic, microcrystalline cellulose, water-soluble hemicellulose, carboxymethylcellulose and sodium carboxymethylcellulose; The above can be used.
[0023]
