Description

本発明は、ミネラル、特にカリウム、カルシウムまたはマグネシウムを多く含有する、高タンパク液状栄養食品組成物に関するものである。   The present invention relates to a high protein liquid nutritional food composition containing a large amount of minerals, particularly potassium, calcium or magnesium.

通常、生命維持に必要な栄養は、食物を咀嚼し経口摂取することにより補給しているが、重体患者や消化器疾患患者等にとっては食物を咀嚼、嚥下することが困難である。ヒトは生命活動を維持するための栄養を毎日摂取することが必要であり、食物からの栄養補給が困難な患者に対しては、厚生労働省が発表した「日本人の食事摂取基準(2010年版)」(非特許文献1)を参考にしながら、流動食等の液状栄養食品組成物の量や種類が選定されている。   Normally, nutrients necessary for life support are supplemented by chewing and orally ingesting food, but it is difficult for a heavy patient, digestive organ disease patient, etc. to chew and swallow food. Humans need to take daily nutrients to maintain their vital activities, and the Japanese Ministry of Health, Labor and Welfare announced the “Japanese Dietary Standards (2010 Edition)” for patients who are difficult to supplement with food. ”(Non-patent Document 1), the amount and type of liquid nutritional food composition such as liquid food are selected.

一方、市販されている一般的な流動食には、タンパク質が4g/100mlしか含まれていないため、タンパク質の一日推奨平均必要量(男性50g、女性40g)を補給するためには、男性で1300ml、女性で1000mlの流動食を毎日摂取しなければならず、より栄養価の高い流動食が望まれていた。   On the other hand, since the general liquid food marketed contains only 4 g / 100 ml of protein, in order to replenish the recommended daily average required amount of protein (male 50 g, female 40 g), males A liquid diet of 1300 ml and 1000 ml for women had to be ingested daily, and a liquid diet with higher nutritional value was desired.

近年、タンパク質が6〜10g/100ml含まれている濃厚流動食が市販され、男性で500〜900ml、女性で400〜700mlの流動食を摂取すればよくなり、入院患者の負担の軽減のみならず、入院患者に食事を提供する医療関係者の労働効率の向上に役立っている。   In recent years, concentrated liquid foods containing 6 to 10 g / 100 ml of protein have been marketed, and it is only necessary to take 500 to 900 ml of liquid foods for men and 400 to 700 ml for women, not only reducing the burden on hospitalized patients. It helps to improve the work efficiency of medical personnel who provide meals to hospitalized patients.

しかしながら、流動食には生命維持に必要なミネラル類などの他の栄養素も配合する必要があるところ、流動食中のタンパク質はミネラル類との相互作用により沈殿・凝集の発生や、流動食自体の粘度の増加が起こる。従って、沈澱・凝集の発生回避や流動食の粘度上昇を低減するためには、ミネラル類の配合量を制限せざるを得なくなり、そのことによるミネラル類の摂取不足は各種ミネラル欠乏症を招きかねず、入院患者や医療関係者にとってもおおきな問題となっていることから、すべての栄養素がバランスよく配合され、総摂取量を減らすことができる流動食が望まれている。   However, it is necessary to mix other nutrients such as minerals necessary for life maintenance in the liquid food, and the protein in the liquid food may cause precipitation / aggregation due to the interaction with the minerals, or the liquid food itself. An increase in viscosity occurs. Therefore, in order to avoid the occurrence of precipitation / aggregation and reduce the viscosity increase of liquid foods, the amount of minerals must be limited, and the inadequate intake of minerals can lead to various mineral deficiencies. Since it is a big problem for hospitalized patients and medical personnel, a liquid food that can balance all nutrients and reduce the total intake is desired.

ミネラル類の一つであるカリウムやカルシウムは、市販されている一般的な流動食には合わせて150〜210mg/100ml、濃厚流動食でも、170〜480mg/100mlしか含まれておらず、カリウムの一日推奨量(男性2500mg、女性2000mg)およびカルシウムの一日推奨量(男性556〜648mg、女性519〜555mg)を補給するためには、男性で600〜2000ml、女性で500〜1700mlの流動食を毎日摂取しなければならない。また、ミネラル類の一つであるマグネシウムは、市販されている一般的な流動食には20mg/100ml、濃厚流動食でも30〜60mg/100mlしか含まれておらず、マグネシウムの一日推奨量(男性350mg、女性300mg)を補給するためには、男性で600〜1800ml、女性で500〜1500mlの流動食を毎日摂取しなければならず、タンパク質とカリウム、カルシウム、マグネシウム等のミネラル類がバランスよく配合された高栄養価流動食が望まれている。   Potassium and calcium, which are one of the minerals, are 150 to 210 mg / 100 ml in total for common liquid foods on the market, and only 170 to 480 mg / 100 ml in concentrated liquid foods. To replenish the recommended daily dose (2500 mg for men, 2000 mg for women) and the recommended daily dose for calcium (556-648 mg for men, 519-555 mg for women), a liquid diet of 600-2000 ml for men and 500-1700 ml for women Must be taken daily. Magnesium, which is one of the minerals, is only 20 mg / 100 ml in a general liquid food marketed, and 30-60 mg / 100 ml in a concentrated liquid food. In order to replenish 350 mg of males and 300 mg of females, liquid diets of 600 to 1800 ml for men and 500 to 1500 ml for women must be ingested daily, and protein and minerals such as potassium, calcium and magnesium are in good balance. A blended high nutritional liquid food is desired.

参考までに、市販されている濃厚流動食に含まれるタンパク質とミネラル類であるマグネシウム、カリウム、およびカルシウムの含量を表1に示す。   For reference, Table 1 shows the contents of magnesium and potassium, which are proteins and minerals, contained in commercially available concentrated liquid foods.

なお、流動食等の液状栄養食品組成物に配合するタンパク質としては、乳タンパクが多用されており、例えば、ミセルカゼイン類が約80重量%及びホエータンパク類が20重量%からなる乳タンパクを約80重量%含有する乳タンパク素材(具体的には、FrieslandCampina社製、商品名「Refit MPC 80」、等)や、カゼイン類を約100重量%含有する乳タンパク素材(カゼインナトリウム、カゼインカルシウム、等)が使用されている。   In addition, milk protein is frequently used as a protein to be blended in a liquid nutritional food composition such as liquid food. For example, milk protein consisting of about 80% by weight of micellar casein and 20% by weight of whey protein is about. Milk protein material containing 80% by weight (specifically, product name “Refit MPC 80” manufactured by Friesland Campina, etc.) and milk protein material containing about 100% by weight of caseins (sodium casein, calcium caseinate, etc.) ) Is used.

表3に示す通り、ミセルカゼイン類を約90重量%、ホエータンパク類を約10重量%を含む乳タンパクを配合した液状栄養食品組成物は、マグネシウムを200mg/100ml添加しても、レトルト直後および7日間保存後の液状栄養食品組成物の粘度は概ね100mPa・s以下という低粘度であった。   As shown in Table 3, the liquid nutritional food composition containing about 90% by weight of micellar casein and about 10% by weight of whey protein can be used immediately after retort, even if magnesium is added at 200 mg / 100 ml. The viscosity of the liquid nutritional food composition after storage for 7 days was as low as about 100 mPa · s or less.

一方、表4に示す通り、ミセルカゼイン類を約80重量%、ホエータンパク類を約20重量%を含む乳タンパクを配合した液状栄養食品組成物は、マグネシウムを80mg/100ml以上添加すると、レトルト直後および7日間保存後の液状栄養食品組成物の粘度は1500mPa・s以上という高粘度となり、液状栄養食品組成物としては不適であった。

実施例2

On the other hand, as shown in Table 4, the liquid nutritional food composition containing about 80% by weight of micellar casein and about 20% by weight of whey protein was added immediately after retort when magnesium was added at 80mg / 100ml or more. The viscosity of the liquid nutritional food composition after storage for 7 days was as high as 1500 mPa · s or more, which was unsuitable as a liquid nutritional food composition.

Example 2
Minerals were added and dissolved while stirring pure water heated to 50 ° C. with a stirrer (“Three-One Motor BL600” manufactured by Shinto Kagaku Co., Ltd.).

It was. Milk protein was added little by little, the stirring speed was increased to 500 to 700 rpm, and stirring was performed until the milk protein was completely dispersed. Thereafter, saccharide was added little by little and dissolved. After 1.5 minutes, preheated fats and oils were added, the container was covered with aluminum foil, and the solution was heated to 60 ° C. with stirring and held for 10 minutes.

その後、溶液をホモミキサー(特殊機化社製、「T.K.ホモミクサーMARKII」)により9,000rpmで2分間プレホモジナイズした。溶液を20℃に冷却し、10%水酸化カリウムを用いて溶液のpHを7.4に調整した。蒸留水を加え所定の重量に調整した。溶液を65℃に加温し、ホモジナイザー(日本APV社製、「APV−1000」)により1段目200bar、2段目50bar、次に1段目600bar、2段目50barで均質化した。溶液100gをレトルトパウチに移し、レトルト加熱殺菌装置(日阪製作所社製、「GPS−40RTGN−FAM」)でレトルトパウチを回転させながら、120℃で20分間レトルト加熱し、表5に示す各原材料の配合量を有する、本発明の液状栄養食品組成物を得た。

Thereafter, the solution was pre-homogenized at 9,000 rpm for 2 minutes using a homomixer (manufactured by Tokushu Kika Co., Ltd., “TK homomixer MARKII”). The solution was cooled to 20 ° C. and the pH of the solution was adjusted to 7.4 using 10% potassium hydroxide. Distilled water was added to adjust to a predetermined weight. The solution was heated to 65 ° C. and homogenized with a homogenizer (“APV-1000” manufactured by Japan APV) at the first stage of 200 bar, the second stage of 50 bar, and then the first stage of 600 bar and the second stage of 50 bar. 100 g of the solution was transferred to a retort pouch and heated at 120 ° C. for 20 minutes while rotating the retort pouch with a retort heat sterilizer (“GPS-40RTGN-FAM” manufactured by Nisaka Manufacturing Co., Ltd.). The liquid nutritional food composition of this invention which has the compounding quantity of was obtained.
