Description
本発明は、経口的に栄養補給を必要とする外科手術患者や高齢者あるいは低栄養状態などの患者が摂取することを目的とした高たんぱく粉末栄養組成物に関する。さらに詳しくは、本発明は、水に難溶解性の乳清たんぱくに、特定の界面活性剤を添加することにより、水に容易に、かつ、透明に溶解することを可能とした水易溶解性高たんぱく粉末栄養組成物およびその製造方法に関するものである。 The present invention relates to a high protein powder nutritional composition intended to be taken by surgical patients who need oral nutrition, elderly patients, or patients with low nutritional status. More specifically, the present invention is a water-solubility that can be easily and transparently dissolved in water by adding a specific surfactant to a whey protein that is hardly soluble in water. The present invention relates to a high protein powder nutritional composition and a method for producing the same.
消化器外科手術患者や高齢者では、たんぱく質、エネルギー、ビタミンあるいは微量元素などの摂取不足状態が長く続くと、免疫機能の低下や新たな疾患の発症を誘引することがある。特に、たんぱく質は、生命を維持し、健康的な生活を営むために、必要不可欠な栄養素の一つであり、外科手術患者や高齢者あるいは経口摂取が不十分な低栄養状態などの患者は、良質のたんぱく質を摂取することが重要となる。このため、余病の併発防止や体力の増強のために、このような患者は、多量に良質のたんぱく質が必要とされる。そこで、たんぱく質を効率よく摂取させるために、日常の食事に追加して与えるたんぱく質原料として、良質の乳たんぱくである乳清たんぱくが必要となる。
たんぱく質原料は、患者などに投与するために、通常、水、牛乳、ジュース、スープなどに溶解させたり、あるいは、ゼリー、プリンなどのデザートや食事に混ぜることが行われている。しかしながら、この場合、粉末状のものは、たんぱく質を高含有できるものの、溶解しにくく、調製に非常に手間がかかるのを免れないという問題がある。このため、水に容易に、かつ、混ぜた食品にできるだけ影響しないようにするため、透明に溶解するたんぱく質を高含有する粉末の栄養補助食品が要望されていた。
In patients with gastrointestinal surgery or the elderly, prolonged intake of proteins, energy, vitamins, trace elements, etc. may induce a decline in immune function and the development of new diseases. In particular, protein is one of the essential nutrients to maintain life and live a healthy life. Surgical patients, elderly people, and patients with malnutrition with poor oral intake, It is important to consume good quality protein. For this reason, such patients require a large amount of high-quality protein in order to prevent coexistence of residual diseases and increase physical strength. Therefore, in order to efficiently ingest protein, whey protein, which is a high-quality milk protein, is required as a protein material to be added to daily meals.
Protein raw materials are usually dissolved in water, milk, juice, soup, etc., or mixed with desserts such as jelly and pudding and meals for administration to patients and the like. However, in this case, although the powdered material can contain a high amount of protein, there is a problem that it is difficult to dissolve and it takes time and effort to prepare. Therefore, there has been a demand for a powdered dietary supplement that contains a protein that dissolves in a transparent manner so that it is easily affected by water and does not affect the mixed food as much as possible.
従来より、難溶解性のたんぱく質原料の多くは乾燥させた粉末原料である場合が多いが、これらを水に添加した場合、粉末自身が水中に分散しながら溶解するよりも、水との接触面で表面だけが水和する方が早く、粉末の表面だけが濡れて内部まで水が浸透しない、いわゆる「ままこ」や「だま」が発生して溶解し難いという問題があった。この問題点を解決するために、水に分散し難い粉末を造粒したり、該粒を多孔質化したりして、構造的に水を早く粉末全体に浸透させる方法が取られたりする。これらの方法により得られた粉末原料は、水に対する溶解性がある程度改善されるが、粉末の水濡れが依然として悪いため、上記処理をした粉末を水に添加した場合、一部の小さい粉末塊は水面に浮き、沈降するのに時間がかかったり、やはり、沈降したままで容易に溶解しない粉末塊も存在することとなっていた。粉末原料の種類にもよるが、一度できてしまった「ままこ」や「だま」を完全に溶解させることは非常に困難であり、この「ままこ」や「だま」を防ぐには、粉末原料を使用の際、高速撹拌しながら徐々に添加する方法、数倍以上の「ままこ」や「だま」にならない粉体と混合して用いる方法、粉体の粒径を大きくする方法或いは粉体の表面を被覆する方法が挙げられるが、手間および溶解性の点で全てを満足させるものではない。 Conventionally, many of the hardly soluble protein raw materials are often dried powder raw materials, but when these are added to water, the contact surface with water rather than the powder itself dissolving while being dispersed in water. However, there was a problem that only the surface of the powder was hydrated faster, so that only the surface of the powder was wet and water did not penetrate into the inside, so-called “mako” and “dama” were generated and difficult to dissolve. In order to solve this problem, a method is adopted in which a powder that is difficult to disperse in water is granulated, or the grain is made porous so that water is structurally rapidly penetrated into the entire powder. The powder raw materials obtained by these methods have some improvement in water solubility, but the water wettability of the powder is still poor, so when the treated powder is added to water, some small powder masses It took a long time to float on the surface of the water and settle down, and there was a powder lump that still settled and did not dissolve easily. Although it depends on the type of powder raw material, it is very difficult to completely dissolve "Mamako" and "Dama" once made. To prevent this "Mamako" and "Dama", powder When using raw materials, add gradually while stirring at high speed, use several times or more of powders that do not become “mako” or “dama”, increase the particle size of the powder, or powder Although the method of coat | covering the surface of a body is mentioned, it does not satisfy all by the point of labor and solubility.
一方、たんぱく質原料と同様に難溶性であるキサンタンガムを易溶性にする製造方法は、既に文献に記載されており（特許文献１参照）、これにはキサンタンガムをＨＬＢ８以上のポリグリセリンまたはショ糖脂肪酸エステル、レシチン、リゾレシチンを乳化剤として処理することによって、キサンタンガムの水和性・分散性を改善した方法が記載されている。しかしながら、この方法は、上記問題を完全に解決したものではなく、また、ショ糖脂肪酸エステル、レシチンの乳化剤は、溶液が白濁してしまうという問題があった。
また、水溶性多糖類の水への溶解性、作業性を改善するために、水溶性多糖類の粉体に、乳化剤として、ソルビタンモノオレエート、ソルビタンモノラウレート、テトラグリセリンモノラウレート、テトラグリセリンモノオレエートなどの乳化剤の混合液をバインダーとして使用し、造粒する水溶性多糖類の製造方法がある（特許文献２参照）が、これらの乳化剤を使用した場合、乳化剤自体に風味の問題があり、添加量を多くすると風味に影響を与えたり、乳化剤自身を溶解した場合、白濁したり、もしくは、長期保存により乳化剤が結晶化するなどの問題があり、透明性が必要とされる用途や長期保存を行う用途では使用できなかった。
On the other hand, a production method for making xanthan gum, which is hardly soluble like a protein raw material, easily soluble, has already been described in the literature (see Patent Document 1), and this includes polyglycerin or sucrose fatty acid ester of HLB8 or higher. , Lecithin and lysolecithin are used as an emulsifier to improve the hydration and dispersibility of xanthan gum. However, this method does not completely solve the above problem, and the sucrose fatty acid ester and lecithin emulsifier have a problem that the solution becomes cloudy.
In order to improve the solubility and workability of water-soluble polysaccharides in water, sorbitan monooleate, sorbitan monolaurate, tetraglycerol monolaurate, tetra There is a method for producing a water-soluble polysaccharide that is granulated by using a mixture of emulsifiers such as glycerin monooleate as a binder (see Patent Document 2), but when these emulsifiers are used, there is a problem with the flavor of the emulsifier itself. Applications that require transparency when there are problems such as increasing the amount added, affecting the flavor, dissolving the emulsifier itself, causing turbidity, or crystallizing the emulsifier due to long-term storage And could not be used for long-term storage.
本発明の目的は、上述の状況を鑑みてなされたもので、水に難溶解性の乳清たんぱくに、特定のポリグリセリン脂肪酸エステルを添加することにより、水に容易に、かつ、透明に溶解することを可能とし、経口的な栄養補給を必要とする外科手術患者や高齢者あるいは低栄養状態の患者などが摂取しやすくした水易溶解性高たんぱく粉末栄養組成物およびその製造方法を提供するものである。 The object of the present invention has been made in view of the above-mentioned circumstances, and is easily and transparently dissolved in water by adding a specific polyglycerin fatty acid ester to a whey protein that is hardly soluble in water. Provided is a water-soluble high protein powder nutritional composition and a method for producing the same, which can be easily taken by surgical patients, elderly people or undernourished patients who require oral nutrition. Is.

Among these, it is preferable to produce by a fluidized bed granulation method.
The following method can be illustrated as a manufacturing method by the fluidized bed granulation method. For example, a protein raw material containing 85% by weight or more of whey protein is put in a granulator, and hot air is fed from below to make the powder flow. In this fluidized bed, at least one surfactant selected from monoesters of decaglycerin and fatty acids having 12 to 14 carbon atoms is 0.002 to 0.02 parts by weight with respect to 1 part by weight of protein.
