Description
本発明は、蛋白質粒子の分散安定性を有するリン酸化水溶性多糖類、並びに当該多糖類を有効成分とする、蛋白質粒子の新規な分散安定剤に関する。
The present invention relates to a phosphorylated water-soluble polysaccharide having dispersion stability of protein particles, and a novel dispersion stabilizer for protein particles containing the polysaccharide as an active ingredient.
乳蛋白質を糖質と共に発酵させた、または有機酸の水溶液に分散させた、酸性乳飲料が知られているが、これにはハイメトキシペクチンやカルボキシメチルセルロース等が乳蛋白質粒子の分散安定剤として用いられてきた。特許文献１に開示されている、大豆から油脂及び蛋白質を分離除去したオカラを原料にして、酸性の条件下で高温加圧抽出して得られた水溶性大豆多糖類をこの分散安定剤として用いると、ペクチン等では達成できないpH4未満の酸性下で、非常に粘度の低い状態で乳蛋白質粒子を分散安定化できる。これにより、ペクチンを添加した糊状感のある重い飲み口の飲料とは異なる、それ以前にないすっきりとした軽い飲み口の酸性乳飲料を作製することが出来る（特許文献２）。
Acidic milk beverages are known in which milk proteins are fermented with sugars or dispersed in an aqueous solution of organic acids. For this purpose, high methoxy pectin and carboxymethyl cellulose are used as dispersion stabilizers for milk protein particles. Has been. As a dispersion stabilizer, water-soluble soybean polysaccharide obtained by high-temperature pressure extraction under acidic conditions using okara from which oil and fat and protein are separated and removed from soybean as disclosed in Patent Document 1 is used. In addition, milk protein particles can be dispersed and stabilized in an extremely low viscosity state under an acidity of less than pH 4 that cannot be achieved with pectin or the like. This makes it possible to produce a refreshing and light-taste acidic milk beverage that is different from a heavy-taste beverage with a pasty feeling to which pectin is added (Patent Document 2).
ところで、酸性乳飲料には、蛋白質を高配合したものや、発酵乳を用いて飲料を作製したものがある。これら飲料を水溶性大豆多糖類を用いてpH4未満の条件で調製すると、非常に酸味の強い飲料になってしまったり、低pHにより乳酸菌が生育できず、生菌タイプの乳酸菌飲料を作製することが出来ないといった問題がある。一方で、前述の水溶性大豆多糖類は、pH4.2を超えるpH域では、蛋白質粒子の充分な分散安定化能を示すことができず、あるいは添加量を増やすと、すっきりとした飲み口を阻害してしまう。そこで、pH4.2より高いpH環境で、且つ低粘度で、乳蛋白質粒子を分散安定できる水溶性多糖類が望まれている。
By the way, acidic milk drinks include those with high protein content and those made with fermented milk. If these beverages are prepared using water-soluble soy polysaccharides under a pH of less than 4, it will become a very sour beverage, or lactic acid bacteria cannot grow due to low pH, and a live type lactic acid bacteria beverage should be produced There is a problem that cannot be done. On the other hand, the above-mentioned water-soluble soybean polysaccharides cannot exhibit sufficient dispersion stabilizing ability of protein particles in the pH range exceeding pH 4.2, or if the amount added is increased, the refreshing mouth is not clean. It will interfere. Therefore, a water-soluble polysaccharide that can disperse and stabilize milk protein particles in a pH environment higher than pH 4.2 and low viscosity is desired.
乳蛋白質は、その等電点以下の酸性下で正電荷を帯びているが、酸性乳飲料中の乳蛋白質粒子を多糖類によって分散させるモデルについて、特にペクチンと水溶性大豆多糖類に関して研究が進められている（非特許文献１）。乳蛋白質粒子の分散安定性に寄与する多糖類は、自身の持つ負電荷によって蛋白質表面にイオン的、または疎水的に結合することで、電気的反発や立体障害によって蛋白質粒子の凝集沈殿が抑えられると考えられている。これまで多糖類の分散安定性を向上させるために、多糖類の持つ負電荷を増やす試みは数多く実施されてきた。例えばセルロースにカルボキシメチル基を導入して負電荷を増やしたカルボキシメチルセルロース（CMC）などである。しかし、CMCは必ずしも乳蛋白質粒子の高い分散安定化力を持つものではない上に、飲料の粘度が高くなり、すっきりとした飲み口の飲料を得ることは難しかった。
Milk proteins are positively charged under acidity below their isoelectric point, but research is progressing on models that disperse milk protein particles in acidic milk beverages with polysaccharides, especially pectin and water-soluble soybean polysaccharides. (Non-Patent Document 1). Polysaccharides that contribute to the dispersion stability of milk protein particles are ionically or hydrophobically bound to the protein surface by their own negative charges, thereby suppressing aggregation and precipitation of protein particles due to electrical repulsion and steric hindrance. It is believed that. To date, many attempts have been made to increase the negative charge of polysaccharides in order to improve the dispersion stability of the polysaccharides. For example, carboxymethyl cellulose (CMC) in which carboxymethyl groups are introduced into cellulose to increase the negative charge. However, CMC does not necessarily have a high dispersion stabilizing power of milk protein particles, and the viscosity of the beverage increases, making it difficult to obtain a refreshing beverage.
従来の水溶性大豆多糖類では安定力が低下する、蛋白質の等電点付近であるpH4.2を超えるpH域でも蛋白質粒子を分散安定化し、低粘度ですっきりした飲み口の酸性乳飲料を提供することを目的とする。
Disperse and stabilize protein particles even in the pH range above pH 4.2, which is near the isoelectric point of protein, where the stability of conventional water-soluble soybean polysaccharides is reduced. The purpose is to do.
本発明者らは、上記の課題に対して鋭意研究を重ねた結果、従来の水溶性大豆多糖類では安定化出来なかったpH4.2を超える等電点付近のpH域で乳蛋白質粒子を分散安定化することを見出し、本発明を完成させた。
As a result of intensive research on the above problems, the present inventors dispersed milk protein particles in the pH range near the isoelectric point exceeding pH 4.2, which could not be stabilized by conventional water-soluble soybean polysaccharides. The present invention has been completed by finding that it is stabilized.

本発明により製造されるリン酸化水溶性大豆多糖類は、特に酸性蛋白飲料において、その蛋白質の分散安定化に対して機能を発揮する。従来の水溶性大豆多糖類では安定化出来ない、蛋白質の等電点付近のpH域でも蛋白質を分散安定化出来る。その際の蛋白質種は、乳蛋白質が酸性飲食品として最も汎用的であり、本発明の分散安定剤の効果が顕著に表われ、好ましい。その際の酸性蛋白飲料の粘度は、蛋白質や分散安定剤の濃度によっても異なるが、例えば後述する実施例１の配合では、本発明の分散安定剤を用いると10mPa・s以下の粘度の酸性蛋白飲料とすることが出来る。また、従来の水溶性大豆多糖類を用いたpH4.2以下の酸性乳飲料では乳酸菌が生存できなかったのに対し、本発明の安定剤を用いると、乳酸菌が生存できるpH域の飲食品が出来るため、乳酸菌醗酵乳を用いた、未加熱生菌タイプの乳酸菌飲料を作製することが出来る。
The phosphorylated water-soluble soybean polysaccharide produced according to the present invention exhibits a function for stabilizing the dispersion of the protein, particularly in acidic protein beverages. Proteins can be dispersed and stabilized even in the pH range near the isoelectric point of proteins, which cannot be stabilized by conventional water-soluble soybean polysaccharides. As the protein species at that time, milk protein is most widely used as an acidic food and drink, and the effect of the dispersion stabilizer of the present invention is remarkably exhibited, which is preferable. The viscosity of the acidic protein beverage at that time varies depending on the concentration of the protein and the dispersion stabilizer. For example, in the formulation of Example 1 described later, the acidic protein having a viscosity of 10 mPa · s or less is used when the dispersion stabilizer of the present invention is used. Can be a beverage. In addition, lactic acid bacteria cannot survive in conventional acidic milk beverages using pH 4.2 or less using water-soluble soybean polysaccharides, whereas when the stabilizer of the present invention is used, foods and drinks in the pH range where lactic acid bacteria can survive are obtained. Therefore, an unheated live bacteria type lactic acid bacteria beverage using lactic acid bacteria fermented milk can be produced.
本発明の蛋白質分散安定剤は、蛋白質濃度が10重量%以下の酸性飲食品において特に効果的であり、好ましくは酸性飲食品に対して0.05～2.0重量%、より好ましくは0.1～1.5重量%、更に好ましくは0.2～1.0重量%添加することにより、蛋白質の等電点付近のpH域付近まで、蛋白質の良好な分散安定性を示す。例えば乳蛋白質では、pH3.4～4.6程度の蛋白飲食品が調製出来、pH3.6～4.4において特に効果的に凝集を抑制できる。分散安定剤が高濃度では、飲食品の風味に影響を与える場合があり、低濃度では分散安定能が発揮できない場合がある。
The protein dispersion stabilizer of the present invention is particularly effective in an acidic food or drink having a protein concentration of 10% by weight or less, preferably 0.05 to 2.0% by weight, more preferably 0.1 to 1.5% by weight, based on the acidic food or drink. More preferably, by adding 0.2 to 1.0% by weight, good dispersion stability of the protein is exhibited up to the pH range near the isoelectric point of the protein. For example, with milk proteins, protein foods and drinks having a pH of about 3.4 to 4.6 can be prepared, and aggregation can be suppressed particularly effectively at pH 3.6 to 4.4. When the dispersion stabilizer is at a high concentration, the flavor of the food or drink may be affected. At a low concentration, the dispersion stability may not be exhibited.
