Description

本発明は、非常に軽い蛋白乾燥加工食品で、湯中への浮きが良好であり、湯戻ししたときの復元性、食感、風味、外観にも優れた即席食品用の蛋白乾燥加工食品に関する。   The present invention relates to a protein dried processed food for instant foods, which is a very light protein dried processed food, has good floatability in hot water, and has excellent restorability, texture, flavor and appearance when reconstituted in hot water. .

従来、フライ麺やノンフライ麺等の即席麺類、即席スープ、即席味噌汁、即席茶漬け等の即席乾燥食品には、鶏卵や畜肉、水産練り製品、海老、油揚げ等の乾燥具材や乾燥加工品が用いられている。乾燥具材および乾燥加工食品には、熱湯を入れた後、1〜5分間で喫食が可能となるように湯戻りが良いことに加え、湯戻り後に乾燥具材及び乾燥加工品が熱湯の上に浮いていることや、素材本来の食感、風味に優れていることが求められる。このような加工食品を製造するに当たり、例えば、マイクロ波を利用した方法が知られている(特許文献1,2)。   Traditionally, instant dried foods such as instant noodles such as fried noodles and non-fried noodles, instant soup, instant miso soup, and instant tea pickles have been used with dried ingredients such as eggs, livestock, marine products, shrimp, and fried chicken. ing. In addition to hot water so that it can be eaten in 1 to 5 minutes after adding hot water to the drying ingredients and dried processed foods, the dried ingredients and dried processed foods are on hot water after returning to hot water. It is required to have a good texture and flavor. In manufacturing such processed foods, for example, methods using microwaves are known (Patent Documents 1 and 2).

しかしながら、これらの方法は、復元性や湯中の浮き等の求められる要求の一部において改善効果は認められるものの、食感が損なわれてしまう等の問題があった。これは、低密度構造は復元性や浮きを向上させるが、乾燥加工品の構造が弱くなってしまい、食感(弾力感)が失われてしまう傾向がある。また、風味付与素材を多く添加すれば、風味が強くなるが、構造を阻害し、乾燥加工品食感(弾力感)を低下させる傾向がある。このため、依然として、湯中の浮き及び湯戻りが良好であることに加えて、食感・風味・外観に優れた即席食品用乾燥蛋白質加工食品が求められている。
本発明は、上記した事情に鑑みてなされたものであり、その目的は、復元性、浮き、風味、食感、外観に優れた蛋白乾燥加工食品を提供することである。
However, although these methods have an improvement effect in some of the required demands such as resilience and floating in hot water, there are problems such as a loss of texture. This is because the low-density structure improves the resilience and floating, but the structure of the dried processed product becomes weak and the texture (elasticity) tends to be lost. Moreover, if a lot of flavor imparting materials are added, the flavor becomes strong, but the structure tends to be impaired, and the texture of the dried processed product (feel of elasticity) tends to be reduced. For this reason, there is still a need for dried protein processed foods for instant foods that are excellent in texture, flavor, and appearance, in addition to good floating and reversion in hot water.
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a dried protein processed food excellent in resilience, float, flavor, texture, and appearance.

本発明者は、鋭意検討の結果、風味付与素材、乾燥蛋白を備え、2層構造を有しており、内層を低密度構造として浮上性を向上させながらも、強い弾力感を維持した蛋白乾燥加工食品を提供することに成功した。すなわち、風味付与素材、乾燥蛋白を備え、低密度内層構造を有し、95℃にて3分間の湯戻し時に所定以上のせん断強度を備えた蛋白乾燥加工食品を提供することに成功し、基本的には本発明を完成するに至った。

本発明において2重構造とは、内層が外層で完全に覆われた構造を示す。
本発明において内層とは、乾燥蛋白加工食品の目視上構造の異なる外層部を除去した部分を示す。
本発明におけるせん断強度は、得られた乾燥蛋白加工食品を95℃以上のお湯で3分間湯戻しした際の測定値を示す。
As a result of intensive studies, the present inventor has provided a flavor imparting material and a dried protein, has a two-layer structure, and has a low-density structure as an inner layer to improve the floating property while maintaining a strong elasticity. Succeeded in providing processed food. That is, it has succeeded in providing a protein-dried processed food comprising a flavor-imparting material and dried protein, having a low-density inner layer structure, and having a shear strength of not less than a predetermined value when reconstituted at 95 ° C. for 3 minutes.

<試験例1> 乾燥蛋白比率の違いによる影響
えび粉末を20質量部、調味料を5質量部、卵白粉末、大豆蛋白粉末を30〜70質量部の範囲で配合し、馬鈴薯澱粉にて100質量部とした。原料粉末に対する加水量は、特に限定されるものではないが、好ましくは原料粉末100質量部に対して30〜80質量部、更に好ましくは40〜70質量部、最も好ましくは、50〜70質量部である。表1には、実施例1〜実施例5、比較例1〜2の各素材の配合割合を示した。
内層かさ比重(g/cm3)の測定方法は、外層をカッター等で除去した内層部分を、正方形又は長方形に成形したサンプルの、各辺の長さ及び重量を測定してサンプルの内層かさ比重を求めた。
せん断力(N/m2)は、数値が小さいほど少ない力で食品が割れる。また、数値が大きくなるほど、力を多く要する。蛋白乾燥加工食品のせん断力は、サンプル1gに95℃以上の湯200mlを加え、3分後に湯きりしたものを測定した値を復元後のせん断力(N/m2)とした。一般に、せん断力が18000(N/m2)を超えると、強い弾力が感じられる。
<Test Example 1> Effect of difference in dry protein ratio Shrimp powder is blended in an amount of 20 parts by mass, seasoning in an amount of 5 parts by mass, egg white powder, and soy protein powder in an amount of 30 to 70 parts by mass, and 100 parts by mass of potato starch.

Asked.
As the shearing force (N / m 2 ) is smaller, the food breaks with less force. Also, the larger the value, the more force is required. The shear force of dried protein processed food was obtained by adding 200 ml of hot water of 95 ° C. or higher to 1 g of a sample, and measuring a value obtained by boiling after 3 minutes to obtain a shear force (N / m 2 ) after restoration. Generally, when the shear force exceeds 18000 (N / m 2 ), a strong elasticity is felt.

せん断力の測定方法に関して、機器はJapan food R&D Institute社製のTexo Graphを用いて、蛋白乾燥加工食品を0.125cm2の歯型プランジャーにて1cm/秒の速度で荷重をかけることにより測定できる。
図1及び図2には、実施例1について、表面と断面の様子を顕微鏡で観察した様子を示した。表面は、孔が少なく、小さいものであり、内部を水の浸入から守っているように見られた。一方、断面は、孔が多く、大きいものであった。このような形態を持っているので、復元性、浮き、食感及び外観に優れていると考えられた。
風味及び復元後の食感についての官能評価は、95℃以上の湯に3分入れた後に湯切りし、せん断力を測定した値が15000(N/m2)のボイルエビをコントロールとして比較した。10人のパネラーに官能評価をしてもらい、コントロールを2点とし、それよりも弾力が強い場合を3点、弾力が弱い場合を1点として、平均2点以上の点数の場合を「弾力あり」、平均2点未満を「柔らかい」とした。
湯中への浮きは、95℃以上の湯に3分入れた際の状態を目視にて確認した。

FIGS. 1 and 2 show the state of the surface and cross section of Example 1 observed with a microscope. The surface was small with few holes and appeared to protect the interior from water ingress. On the other hand, the cross section was large with many holes. Since it had such a form, it was thought that it was excellent in the resilience, the float, the food texture, and the external appearance.
The sensory evaluation of the flavor and texture after restoration was compared with a control of boiled shrimp having a value of 15000 (N / m 2 ) after measuring the shearing force after putting it in hot water at 95 ° C. or higher for 3 minutes. Ten panelists have a sensory evaluation, with 2 points of control, 3 points when the elasticity is stronger, 1 point when the elasticity is weak, and an average score of 2 points or more. “Average” less than 2 points was defined as “soft”.
The float in the hot water was visually confirmed when it was placed in hot water at 95 ° C. or higher for 3 minutes.
The volume was obtained by measuring the height of the sphere and calculating the volume of the sphere (4/3 × πr 3 ).
Water was added to the formulation shown in Table 1 and mixed to prepare a dough (fabric manufacturing process), and this dough was processed into a subdivided dough (granular) of about 4 mm (subdividing process). Next, the divided dough was expanded and dried (expanded drying step). Swelling drying was performed using microwave heating drying under the conditions (2,000 J / g) of a subdivision 60 g, a microwave output of 2.0 kw, and a microwave heating time of 60 seconds.
The results are shown in Table 1.

上記<イカ団子の製造>、<鶏肉団子の製造>及び<こんにゃくほうれん草粒の製造>で得られた乾燥品の比重、せん断力、官能評価について試験例1と同様の方法を実施した。結果を表5に示した。その結果、15000N/m2以上の弾力のある食感となった。
<Manufacture of konjac spinach grains>
25 parts by weight of egg white powder, 20 parts by weight of separated soy protein, 5 parts by weight of spinach powder, 4 parts by weight of salt, 1 part by weight of sugar, 2 parts by weight of ammonium bicarbonate, 1 part by weight of konjac powder, 1.5 parts by weight of sodium glutamate, 1 part by mass of sodium polyphosphate and 32 parts by mass of water were mixed with stirring in a food processor, and sieved to obtain a granular dough of 5.6 mm to 8 mm (subdivision step). This was microwave-heated under the condition of 1800 J / g to obtain a dried product (bamboo pod grass grains) (expanded drying step).
<Confirmation of each dried product>
The same method as in Test Example 1 was performed on the specific gravity, shear force, and sensory evaluation of the dried product obtained in <Manufacture of squid dumpling>, <Manufacture of chicken dumpling>, and <Manufacture of konjac spinach grains>. The results are shown in Table 5. As a result, a texture with elasticity of 15000 N / m 2 or more was obtained.

このように本実施形態によれば、復元性、浮き、食感及び外観に優れた蛋白乾燥加工食品を提供することができた。この蛋白乾燥加工食品は、比重が軽いので、少重量で数量を多く添加することができる。例えば、即席食品に使用する場合には、湯面に浮いて、大きく復元することから、見栄えが良いという利点がある。また、喫食に際しても、所定の時間内に復元するので、畜肉や魚介類に特有の食感(例えば、歯ごたえのある弾力)を楽しむことができる。   As described above, according to this embodiment, it is possible to provide a dried protein processed food excellent in resilience, floating, texture, and appearance. Since this protein-dried processed food has a low specific gravity, it can be added in small quantities and in large quantities. For example, when it is used for instant food, it floats on the hot water surface and is greatly restored, so that it has the advantage of good appearance. In addition, since the food is restored within a predetermined time, it is possible to enjoy a texture (for example, a crunchy elasticity) peculiar to livestock meat and seafood.
