Description

本発明は、電子レンジなどで温めるだけで食べることができる容器入り即食リゾットおよびその製造方法に関する。   The present invention relates to a containerized ready-to-eat risotto that can be eaten simply by heating in a microwave oven or the like, and a method for producing the same.

リゾットとは、イタリア料理の一つで、油で炒めた米をスープで煮込むことによって調理されるもので、米飯の食感が、粒感があり、且つ、アルデンテ様の歯応えのあることが特徴である。しかし、調理したリゾットを長期間保管すると、米飯がスープを吸収し、ふやけてしまうため、リゾット本来の食感が失われる。   Risotto is an Italian dish that is cooked by cooking rice that has been fried in oil with soup. The texture of the cooked rice is grainy and has a crunchy texture. It is. However, if the cooked risotto is stored for a long period of time, the cooked rice will absorb the soup and swell, so the original texture of the risotto is lost.

そこで、従来は、常温やチルド環境で長期間保管される加工食品のリゾットを提供する場合、米飯とスープを、それぞれ別々に、充填・調理され、喫食時にそれらを合わせることで上記問題を解決していた。例えば、容器包装米飯と、レトルトパウチに充填されたスープがセットされた加工食品がある。しかし、米とスープが一緒に煮込まれていないために、リゾット本来の煮込み感がないという別の課題が生じる。   Therefore, conventionally, when providing risottos of processed foods that are stored at room temperature or in a chilled environment for a long time, rice and soup are filled and cooked separately, and the above problems are solved by combining them at the time of eating. It was. For example, there is a processed food in which a container-wrapped cooked rice and a soup filled with a retort pouch are set. However, because rice and soup are not boiled together, another problem arises that the risotto does not have the original boiled feeling.

又、リゾットと同じような米飯の煮込みメニューとして、粥や雑炊がある。それらの加工食品も、長期間保管すると、同様に米飯がふやけたり、形が崩れるといった問題があった。それを解決するために、米を煮込む際に、水に澱粉分解物(特許文献1)や、ゼラチン(特許文献2)を溶解したり、米を100℃以上で加圧蒸煮した後、水と供に炊飯すること(特許文献3)が行われている。しかし、これらの方法により、粥や雑炊の米飯のふやけや、形崩れを抑えることはできても、本来のリゾットに求められる、粒感があり、且つ、アルデンテ様の歯応えのある食感を実現することはできなかった。   In addition, there are rice bowls and miscellaneous cooking as a menu for stewed rice similar to risotto. When these processed foods are also stored for a long period of time, there is a problem that the cooked rice is similarly burned or the shape is lost. In order to solve this problem, when the rice is boiled, the starch decomposition product (Patent Document 1) and gelatin (Patent Document 2) are dissolved in water, or the rice is steamed under pressure at 100 ° C. or higher. Cooking rice (Patent Document 3) is performed. However, with these methods, even if it can suppress the simmering of rice cakes and miscellaneous cooked rice and the loss of shape, it has the grainy texture required by the original risotto and has a texture that is crisp like Aldente. I couldn't.

本発明により、米飯とスープが一緒に調理された容器入り即食リゾットにおいて、その米飯の喫食時の食感が、リゾット本来の粒感があり、且つ、アルデンテ様の歯応えを有するものを得ることができる。   According to the present invention, in a containerized instant risotto cooked together with cooked rice and soup, the texture of the cooked rice at the time of eating can be obtained with risotto's original grain texture and having an aldente-like texture it can.

本発明の容器入り即食リゾットの物性について、以下に述べる。
リゾットの物性
本発明の方法により、その米飯の物性値をテンシプレッサーで測定した時、米飯粒全体のバランス度Hが0.03〜0.21の範囲で、且つ、バランス度Aが0.02〜0.11の範囲にある、本格的なリゾットの米飯の食感を味わうことができる、容器入り即食リゾットを得ることができる。ここで、米飯粒全体のバランス度Hが0.03〜0.21で、且つ、バランス度Aが0.02〜0.11の範囲にあるとき、粒感があり、且つ、アルデンテ様の歯応えを感じられる。一方、米飯粒全体のバランス度Hが0.03より小さいか、もしくは、バランス度Aが0.02より小さくなると、米飯粒全体の糊化が不十分で、食感としては硬すぎる。一方、バランス度Hが0.21より大きいか、もしくは、バランス度Aが0.11より大きくなると、米飯粒内部まで糊化が進み、アルデンテ様の歯応えが失われる。
The physical properties of the instant meal risotto in the container of the present invention will be described below.
Physical Properties of Risotto According to the method of the present invention, when the physical property value of the cooked rice was measured with a tensipressor, the balance degree H of the whole cooked rice grain was in the range of 0.03 to 0.21, and the balance degree A was 0.02. An instant risotto in a container that can taste the texture of authentic risotto cooked rice in the range of ˜0.11 can be obtained. Here, when the degree of balance H of the whole cooked rice grain is 0.03 to 0.21 and the degree of balance A is in the range of 0.02 to 0.11, there is a graininess and an Aldente-like tooth response. Can feel. On the other hand, when the balance degree H of the whole cooked rice grain is less than 0.03 or the balance degree A is less than 0.02, the whole cooked rice grain is insufficiently gelatinized and is too hard as a texture. On the other hand, when the degree of balance H is greater than 0.21 or the degree of balance A is greater than 0.11, gelatinization proceeds to the inside of the cooked rice grains, and Aldente-like texture is lost.

又、本発明における、「テンシプレッサー」とは、タケトモ電機製の引張圧縮試験装置を示す。「米飯粒全体のバランス度」は、上記テンシプレッサーを用いて、参考文献(日本食品科学工学会誌 Vol.45,No.7,398-407(1998))の実験方法を基にした次の方法により測定することができる。すなわち、

(3)前記放置後の米飯粒一つを、測定試料載置面を有する、該測定試料載置面の垂線方向に移動可能な試料台と、直径30mmの円形の試料接触面を一端に有するプランジャーであって、前記試料接触面が前記測定試料載置面に対向する位置に固定して配置されているプランジャーとを備えるテンシプレッサー(タケトモ電機製の引張圧縮試験装置)の前記測定試料載置面上に置く。
(4)前記試料台と前記プランジャーとを2mm/秒の速度で接近させ、前記米飯粒を、前記試料台の測定試料載置面と前記プランジャーの試料接触面との間で、米飯の厚みの25%分を圧縮し、引き続き、前記試料台と前記プランジャーとを2mm/秒の速度で遠ざけ、前記プランジャーの試料接触面から前記米飯粒を引き離す。
(5)前記試料台と前記プランジャーとを2mm/秒の速度で接近させ、前記米飯粒を、前記試料台の測定試料載置面と前記プランジャーの試料接触面との間で、米飯の厚みの90%分を圧縮し、引き続き、前記試料台と前記プランジャーとを2mm/秒の速度で遠ざけ、前記プランジャーの試料接触面から前記米飯粒を引き離す。この操作の間、米飯粒からプランジャーが受ける応力を、圧縮応力が正の値、引張応力が負の値となるように経時的に連続に測定する。
(6)前記試料台の移動距離を横軸、応力を縦軸とする座標上に、前記(5)での測定の結果に基づいてグラフを描画した場合の応力の最大値a、及び、応力の最小値の絶対値bを記録するとともに、応力の数値が0〜正である前記グラフの部分と前記横軸とにより包囲される領域の面積A、及び、応力の数値が負〜0である前記グラフの部分と前記横軸とにより包囲される領域の面積Bを算出する。(図1参照)
(7)最小値の絶対値b/最大値aの値をバランス度Hとして、面積B/面積Aの値をバランス度Aとして算出する。
In the present invention, “tensipressor” refers to a tensile / compression test apparatus manufactured by Taketomo Electric. “The degree of balance of the whole cooked rice grains” is the following method based on the experimental method of the reference (Japan Food Science and Technology Society Vol.45, No.7, 398-407 (1998)) using the above-mentioned tensipressor. Can be measured. That is,
(1) Using a microwave oven, warm the above-mentioned containerized ready-to-eat risotto to a product temperature of 70 ° C. or higher, preferably 70 ° C. to 100 ° C. Specific conditions for the microwave oven include 500 to 600 W and a condition of 1 minute 30 seconds to 2 minutes, but the heating conditions vary depending on the internal volume and the shape and size of the container.

Place on the mounting surface.
(4) The sample stage and the plunger are brought closer to each other at a speed of 2 mm / second, and the cooked rice grains are placed between the measurement sample placement surface of the sample stage and the sample contact surface of the plunger. After compressing 25% of the thickness, the sample stage and the plunger are moved away at a speed of 2 mm / second, and the rice grains are pulled away from the sample contact surface of the plunger.
(5) The sample stage and the plunger are brought closer to each other at a speed of 2 mm / second, and the cooked rice grains are placed between the measurement sample placement surface of the sample stage and the sample contact surface of the plunger. After compressing 90% of the thickness, the sample stage and the plunger are moved away at a speed of 2 mm / sec, and the cooked rice grains are pulled away from the sample contact surface of the plunger. During this operation, the stress received by the plunger from the cooked rice grains is continuously measured over time so that the compressive stress has a positive value and the tensile stress has a negative value.
(6) The maximum stress value a and the stress when the graph is drawn based on the measurement result in (5) on the coordinate with the moving distance of the sample table as the horizontal axis and the stress as the vertical axis.

次に、容器入りリゾットの製造方法について、以下に述べる。
無洗米又は生米
本発明には水を添加吸収させていない無洗米又は生米を用いる。無洗米を得るための無洗化方法には、水を使う湿式や、水を使わない乾式、および、タピオカや糠の付着力を利用したものがあるが、特に制限はない。又、適宜、無洗米又は生米に、玄米、発芽玄米、黒米、粟、黍、稗、胡麻、アマランサス、キヌア、豆類、麦類等の穀物を適宜、ブレンドしても構わない。
Next, a method for producing a container risotto will be described below.
The non-bran rice or raw rice present invention using a pre-washed rice or raw rice that has not been added absorb water. There are no particular restrictions on the washing method for obtaining washing-free rice, including wet methods using water, dry methods that do not use water, and tapioca and rice bran adhesion. In addition, grains such as brown rice, germinated brown rice, black rice, rice bran, rice bran, rice bran, sesame, amaranthus, quinoa, beans, wheat and the like may be appropriately blended with non-washed rice or raw rice.

「水を添加吸収させていない無洗米又は生米」とは、無洗米又は生米を、常法により水で洗浄したり、水中に人為的に浸漬するなどして水を吸収させていないものを指し、その水分含量としては、11質量%〜22質量%、好ましくは、12質量%〜20質量%である。洗米や水浸漬により、容器に充填する前に、米が水を吸収して水分含量が22質量%以上になってくると、デキストリンを溶解したスープと合わせて調理をする際に米の澱粉の糊化が促進してしまう。その結果、米飯は多くの水分を吸収し、アルデンテ様の歯応えのある食感が失われる。又、米が水を吸収していても、スープ中のデキストリンの濃度を高くすることで、スープから米への水分移行速度を抑制できるが、調理後のスープのベタツキが強くなり、リゾットとしての美味しさが失われる。一方、水を添加吸収させていない無洗米又は生米の水分含量が少なくなり過ぎると、調理殺菌時に米粒の割れが顕著になる傾向になる。   “Non-washed rice or fresh rice without added water absorption” means that non-washed rice or fresh rice is not absorbed by washing it with water or by artificially immersing it in water. The water content is 11% by mass to 22% by mass, preferably 12% by mass to 20% by mass. When the rice has absorbed water and the water content is 22% by mass or more before being filled into the container by washing with water or dipping in water, the starch content of the rice starch is reduced when cooking with soup containing dextrin. Gelatinization will be promoted. As a result, the cooked rice absorbs a lot of water and loses the texture of Aldente-like texture. In addition, even if the rice absorbs water, increasing the concentration of dextrin in the soup can suppress the rate of water transfer from the soup to the rice, but the soup after cooking will become more sticky, and as a risotto Deliciousness is lost. On the other hand, if the water content of unwashed rice or raw rice that has not been added and absorbed with water becomes too small, cracking of the rice grains tends to become prominent during cooking sterilization.

又、「水を添加吸収させていない無洗米又は生米」は、容器に充填する前に、実質的に水を添加することなく蒸気加熱処理したものであることが好ましい。この蒸気加熱処理を施すことで、米粒の表層に糊化層ができ、米粒内部への水の浸透を抑制する。その結果、表層と内部の水分勾配をより大きくすることができ、アルデンテ様の歯応えのある食感をより感じ取ることができる。ここで、実質的に水を加えることなく蒸気加熱処理を施すとは、米粒が水中に浸るような程度にまで水を加えることなく蒸気加熱処理を施すことを意味する。例えば、無洗米に飽和水蒸気を接触させて加熱する方法、或いは米に対し、過熱水蒸気を接触させて加熱する方法等を掲げることができる。蒸気加熱条件としては、例えば、90℃〜120℃で1分間〜90分間、好ましくは、常圧の飽和水蒸気で、4分間〜30分間の条件を掲げることができる。   In addition, “washless rice or fresh rice to which water is not added and absorbed” is preferably steam-heated without substantially adding water before filling the container. By performing this steam heat treatment, a gelatinized layer is formed on the surface layer of the rice grain, and water penetration into the inside of the rice grain is suppressed. As a result, the moisture gradient between the surface layer and the inside can be further increased, and a texture with a crisp texture like Ardente can be sensed more. Here, performing steam heat treatment without substantially adding water means performing steam heat treatment without adding water to such an extent that rice grains are immersed in water. For example, a method of heating by bringing saturated steam into contact with non-washed rice, or a method of heating by bringing superheated steam into contact with rice can be listed. As steam heating conditions, for example, conditions of 90 ° C. to 120 ° C. for 1 minute to 90 minutes, preferably normal pressure saturated water vapor, for 4 minutes to 30 minutes can be mentioned.

デキストリンを溶解してなる、調味された液状物
本発明において「調味された液状物」とは水を媒体とする液状物であり、典型的には、水が、塩、醤油、砂糖などの調味料や、各種だし、油、各種食材などにより適宜味付けされたものである。
Seasoned liquid product obtained by dissolving dextrin In the present invention, the “seasoned liquid product” is a liquid product using water as a medium. Typically, water is a seasoned product such as salt, soy sauce or sugar. It is appropriately seasoned with ingredients, various soup stocks, oil, various foods, and the like.

本発明の一実施形態では、調味された液状物はスープの一部又は全部として提供されることができる。典型的には、水に、必要に応じて玉葱、人参、馬鈴薯、トマト、キノコ類などの野菜、牛肉、豚肉、鶏肉といった肉類や、海老、イカ、ホタテなどの魚介類のような各種具を加え、醤油、砂糖などの調味料、各種だし、油などにより適宜着味し、加熱調理することによりスープを得る。こうして得られるスープのうち液状の部分(スープ全部が液状のこともあり得る)を「調味された液状物」と規定することができる。スープのうち非液状の部分(例えば、目開き2.0mm程度のメッシュで常温(25℃)にてスープを濾過したときにメッシュ上に残留する成分、典型的には固体状の具)は「調味された液状物」には包含されない。   In one embodiment of the present invention, the seasoned liquid can be provided as part or all of the soup. Typically, water, vegetables such as onions, carrots, potatoes, tomatoes and mushrooms, meat such as beef, pork and chicken, and various items such as seafood such as shrimp, squid and scallops as needed. In addition, seasonings such as soy sauce and sugar, various soup stocks, oils, etc., are appropriately seasoned and cooked to obtain a soup. Among the soups thus obtained, the liquid portion (the whole soup may be liquid) can be defined as “seasoned liquid”. The non-liquid portion of the soup (for example, a component that remains on the mesh when the soup is filtered at room temperature (25 ° C.) with a mesh having an opening of about 2.0 mm, typically a solid ingredient) is “ It is not included in “seasoned liquid”.

本発明の他の一実施形態では、液状物の調味は、後述する原料充填工程の際に容器中で行ってもよい。   In another embodiment of the present invention, the seasoning of the liquid material may be performed in a container during the raw material filling step described later.

本発明は、調味された液状物にデキストリンが溶解されていることを特徴とする。デキストリンは調味の前、中、後のいずれの段階で液状物に溶解されてもよい。また、液状物へのデキストリンの溶解は後述する原料充填工程の際に容器中で行ってもよい。   The present invention is characterized in that dextrin is dissolved in a seasoned liquid. Dextrin may be dissolved in the liquid at any stage before, during or after seasoning. Moreover, you may perform the melt | dissolution of dextrin in a liquid substance in a container in the case of the raw material filling process mentioned later.

調味された液状物には更に、デキストリンの保水能を補う目的で、スープのベタツキに影響を与えない範囲で、ゼラチンや、澱粉、加工澱粉、ペクチン、キサンタンガム、寒天などの多糖類が適宜添加されてもよい。   In addition to the seasoned liquid, polysaccharides such as gelatin, starch, modified starch, pectin, xanthan gum, and agar are added as appropriate so as not to affect the stickiness of the soup in order to supplement the water retention ability of dextrin. May be.

本発明で用いられるデキストリンとは、原料澱粉を低分子化したもので、乾式分解したもの(焙焼デキストリン)でも、湿式分解したもの(酸処理澱粉、酸化澱粉、酵素変性デキストリン)でも良い。又、これらのデキストリンに、水素添加し還元したものを使用しても良い。   The dextrin used in the present invention is obtained by reducing the molecular weight of raw starch, and may be dry-decomposed (roasted dextrin) or wet-decomposed (acid-treated starch, oxidized starch, enzyme-modified dextrin). These dextrins may be used after hydrogenation and reduction.

上記デキストリンは、DEが5〜20のものであることが好ましい。DEが5より小さいデキストリンは、調味された液状物の保水能を高める効果は高いが、デキストリン自身が米粒の内部に余り浸透しないため、米澱粉の糊化を効果的に抑制することができないし、調味された液状物のベタツキも強くなる。一方、DEが20より大きいと、デキストリンが米粒の内部に浸透しやすいが、米澱粉の糊化を抑制する効果は弱く、又、調味された液状物の風味に与える影響も大きく、甘みが強くなる。   The dextrin preferably has a DE of 5-20. A dextrin with a DE of less than 5 is highly effective in enhancing the water retention capacity of the seasoned liquid, but the dextrin itself does not penetrate much into the interior of the rice grain, so it cannot effectively suppress gelatinization of rice starch. The stickiness of the seasoned liquid becomes stronger. On the other hand, when DE is larger than 20, dextrin easily penetrates into the inside of the rice grain, but the effect of suppressing gelatinization of rice starch is weak, and the influence on the flavor of the seasoned liquid is large, and the sweetness is strong. Become.

DEが5〜20の大きさのデキストリンは、調味された液状物の保水能を高める効果においては、DE5未満のデキストリンよりも小さいが、米粒の内部にも浸透し、米澱粉の糊化を効果的に抑制する。その結果、調味された液状物から米への水分移行速度が抑えられ、且つ、調味された液状物の風味・物性に与える影響を小さくすることができる。   Dextrins with a DE of 5 to 20 are smaller than dextrins with a DE less than DE5 in the effect of enhancing the water retention capacity of seasoned liquids, but also penetrate into the interior of rice grains and are effective in gelatinizing rice starch Suppress it. As a result, the moisture transfer rate from the seasoned liquid to rice can be suppressed, and the influence on the flavor and physical properties of the seasoned liquid can be reduced.

こうしたデキストリンの液状物中の添加量は、「液状物の平均DE値」が所定の範囲となるように決定することができる。好ましくは、調味された液状物の平均DE値が0.5〜4.0、より好ましくは、0.6〜3.5になるように、DE5〜20のデキストリンを配合する。DE5〜20のデキストリンに加えて、必要に応じて5〜20以外のDE値を有するデキストリンを配合することにより、液状物の平均DE値を上記範囲に調整することもできる。液状物の平均DE値が0.5より小さい場合(つまり、DE値の小さいデキストリンを液状物中に多く配合した場合)には、上記のように、米澱粉の糊化を効果的に抑えられないし、調味された液状物のベタツキが強くなる。一方、液状物の平均DE値が4.0より大きくなると、米澱粉を抑制する効果が弱く、調味された液状物の甘味が強く感じられるようになる。なお、上記した「液状物の平均DE値」とは、液状物中に溶解されるデキストリンのDE値に、当該デキストリンの液状物中における比率(溶解されたデキストリンの重量/デキストリンを溶解してなる液状物の重量)を掛けて得られる値である。複数種のデキストリンが使用される場合には、各デキストリン種について上記の手順で算出された値の和が「液状物の平均DE値」にほかならない。例えば、DE値10のデキストリンを9質量%、DE値5のデキストリンを6質量%それぞれ溶解してなる液状物の平均DE値は、次の式で求めることができる。
液状物の平均DE値=10×0.09+5×0.06=1.2
即ち、上記の例の場合の液状物の平均DE値は1.2ということになる。
The amount of dextrin added to the liquid can be determined so that the “average DE value of the liquid” is within a predetermined range. Preferably, a dextrin having a DE of 5 to 20 is blended so that the average DE value of the seasoned liquid is 0.5 to 4.0, more preferably 0.6 to 3.5. In addition to the dextrin of DE5-20, the average DE value of a liquid substance can also be adjusted to the said range by mix | blending the dextrin which has DE values other than 5-20 as needed. When the average DE value of the liquid is less than 0.5 (that is, when a large amount of dextrin having a small DE value is added to the liquid), the gelatinization of rice starch can be effectively suppressed as described above. Also, the stickiness of the seasoned liquid becomes stronger. On the other hand, when the average DE value of the liquid material is larger than 4.0, the effect of suppressing rice starch is weak, and the sweetness of the seasoned liquid material is felt strongly. The above-mentioned “average DE value of the liquid substance” means the ratio of the dextrin in the liquid substance to the DE value of the dextrin dissolved in the liquid substance (the weight of the dissolved dextrin / dextrin is dissolved). It is a value obtained by multiplying the weight of the liquid material). When multiple types of dextrin are used, the sum of the values calculated by the above procedure for each dextrin type is nothing but the “average DE value of liquid material”. For example, the average DE value of a liquid material obtained by dissolving 9% by mass of dextrin having a DE value of 10 and 6% by mass of dextrin having a DE value of 5 can be obtained by the following equation.
Average DE value of liquid material = 10 x 0.09 + 5 x 0.06 = 1.2
That is, the average DE value of the liquid material in the above example is 1.2.

原料充填工程
原料充填工程は、水を添加吸収させていない無洗米又は生米と、デキストリンを溶解してなる、調味された液状物とを容器に充填する工程である。
Raw material filling step The raw material filling step is a step of filling a container with unwashed rice or raw rice to which water has not been added and absorbed, and a seasoned liquid material obtained by dissolving dextrin.

容器中にはさらに、必要に応じて、玉葱、人参、馬鈴薯、トマト、キノコ類などの野菜、牛肉、豚肉、鶏肉といった肉類や、海老、イカ、ホタテなどの魚介類のような各種具が充填されてもよい。これらの成分は上述したようにスープ調製段階に由来するものであってもよいし、原料充填工程で新たに添加されたものであってもよい。   The container is further filled with vegetables such as onions, carrots, potatoes, tomatoes and mushrooms, meat such as beef, pork and chicken, and various items such as seafood such as shrimp, squid and scallops as needed. May be. These components may be derived from the soup preparation stage as described above, or may be newly added in the raw material filling step.

無洗米又は生米と、デキストリンを溶解してなる調味された液状物との配合比は、米1重量部に対し、当該液状物が1.5〜6.7重量部、好ましくは、1.7〜5.5重量部であることが望ましい。上記範囲より、液状物が多くなってくると、粥状になり、リゾットの食感として不適になる。一方、液状物が少なくなってくると、米飯の食感が硬くなり過ぎてしまう。   The blending ratio of the non-washed rice or raw rice and the seasoned liquid obtained by dissolving dextrin is 1.5 to 6.7 parts by weight, preferably 1. It is desirable that it is 7-5.5 weight part. If the amount of liquid is increased from the above range, it becomes cocoon-like and unsuitable as a risotto texture. On the other hand, when the liquid content decreases, the texture of the cooked rice becomes too hard.

容器としては、密封することが可能な、耐熱性の合成樹脂製の袋状乃至成形容器であればよく、容器の大きさや形状については特に限定されるものではないが、概ね一食分の大きさであることが望ましい。   The container may be a heat-resistant synthetic resin bag-shaped or molded container that can be sealed, and the size and shape of the container are not particularly limited, but are generally the size of one serving. It is desirable that

密封工程
密封工程では、上述の各種材料が充填された容器を密封する。
Sealing process In the sealing process, the container filled with the various materials described above is sealed.

調理殺菌工程
調理殺菌工程は、密封工程後の前記容器を加熱することにより、前記容器内に密封充填された、前記無洗米又は生米と前記液状物とからなる内容物を、米飯を含むリゾットに調理するとともに殺菌する工程である。
Cooking sterilization process The cooking sterilization process is a risotto containing cooked rice, the contents of the washed rice or fresh rice and the liquid material, hermetically filled in the container by heating the container after the sealing process. It is a process of cooking and sterilizing.

加熱方法としては、例えば、レトルト釜などの圧力調整できる圧力釜により、内容物が密封された容器を加熱する方法が挙げられる。この方法により、容器内に気体が含まれていたとしても、容器を破袋させることなく加熱して、内容物を調理及び殺菌することができる。この場合、所定の殺菌価が達成される条件で加熱を行えばよい。これにより、常温やチルド流通で長期間保存できるリゾットを提供することもできる。   Examples of the heating method include a method of heating a container whose contents are sealed with a pressure cooker such as a retort cooker capable of adjusting pressure. By this method, even if gas is contained in the container, the contents can be cooked and sterilized by heating without breaking the container. In this case, heating may be performed under conditions that achieve a predetermined sterilization value. Thereby, the risotto which can be preserve | saved for a long time by normal temperature or chilled distribution can also be provided.

また、加熱条件としては、常温流通させるための殺菌価としてF120℃=4分以上という条件を例示することができ、また、チルド流通させるための殺菌価としてはF100℃=10〜30分という条件を例示することができる。   In addition, the heating condition can be exemplified by a condition of F120 ° C. = 4 minutes or more as a sterilization value for circulating at normal temperature, and a condition of F100 ° C. = 10-30 minutes as a sterilization value for circulating chilled Can be illustrated.

冷蔵工程
冷蔵工程は、調理殺菌工程後の前記リゾットを冷蔵する工程である。調理殺菌工程後前記容器ごと冷蔵する。この冷蔵により、リゾット中の米飯が老化し、スープ中の水分を要求する能力が低下するため、リゾット様の歯応えのある食感を、長時間、維持するのに適している。冷蔵は、−10℃〜10℃の雰囲気下で、2時間〜72時間、より好ましくは、−5℃〜5℃で、4時間〜60時間の条件で行うのが良い。冷蔵温度が10℃より高くなってくると、老化速度が遅くなり、一方、−10℃より低くなると、リゾットが凍結するため、糊化状態を維持し、老化が抑制されてしまう。
Refrigeration process The refrigeration process is a process of refrigeration of the risotto after the cooking sterilization process. The container is refrigerated after the cooking sterilization step. This refrigeration ripens the cooked rice in the risotto and reduces the ability to require moisture in the soup, so it is suitable for maintaining a risotto-like crunchy texture for a long time. Refrigeration is preferably performed under an atmosphere of −10 ° C. to 10 ° C. for 2 hours to 72 hours, more preferably −5 ° C. to 5 ° C. for 4 hours to 60 hours. When the refrigeration temperature is higher than 10 ° C., the aging rate is slowed. On the other hand, when it is lower than −10 ° C., the risotto is frozen, so that the gelatinization state is maintained and aging is suppressed.

このようにして、本発明の容器入り即食リゾットを得ることができる。得られた容器入り即食リゾットは、ホットベンダーあるいは電子レンジや熱水で加熱して喫食することができる。   In this way, the instant food risotto in the container of the present invention can be obtained. The containerized ready-to-eat risotto can be eaten by heating with a hot bender, microwave oven or hot water.

上記表3のように、実施例1から実施例7は、スープから米への水分移行が抑えられているため、米飯は粒感があり、アルデンテ様の歯応えがあった。又、スープのベタツキも弱く、本格的なリゾットを味わうことができた。これを20℃−7日間保存した後も、製造直後からの変化は小さく、許容範囲内の食感・風味を維持することができた。   As shown in Table 3 above, in Examples 1 to 7, the moisture transfer from the soup to the rice was suppressed, so the cooked rice had a grain feel and had an Ardente-like texture. Also, the stickiness of the soup was weak and I was able to taste a full-fledged risotto. Even after this was stored at 20 ° C. for 7 days, the change from immediately after production was small, and the texture and flavor within the allowable range could be maintained.

それらに対して、比較例2は、パウチに充填するまでに、米が水を含むため、調理時に糊化が促進し、米の内部までスープが多く浸透した結果、米飯はアルデンテ様の歯応えが失われていた。これを、20℃−7日間保存すると、さらに食感が柔らかくなった。   On the other hand, in Comparative Example 2, because rice contains water before filling in the pouch, gelatinization is promoted during cooking, and as a result of the large amount of soup penetrating into the rice, the rice has an Aldente-like texture. It was lost. When this was stored at 20 ° C. for 7 days, the texture became even softer.

尚、粒感があり、アルデンテ様の歯応えのある食感は、テンシプレッサーで測定した米飯粒のバランス度Hとバランス度Aで説明することができ、それらの値が所定の範囲内に入っていると本格的なリゾットの食感を味わうことができる。   In addition, there is a grain texture, and the texture with a crunchy texture of Aldente can be explained by the balance degree H and the balance degree A of the cooked rice grains measured with a tensipresser, and those values fall within a predetermined range. If you are, you can taste the texture of authentic risotto.

上記表1と表2より、実施例1から実施例7の米飯粒は、バランス度Hが0.03〜0.21で、且つ、バランス度Aが0.02〜0.11の範囲内にあることで、粒感があり、アルデンテ様の歯応えを感じられた。一方、アルデンテ様の歯応えが感じられない、比較例2の米飯粒や、比較例3〜5の米飯・粥も、上記範囲内には入っていなかった。   From Table 1 and Table 2, the cooked rice grains of Examples 1 to 7 have a balance degree H of 0.03 to 0.21 and a balance degree A of 0.02 to 0.11. There was a feeling of grain, and I felt the texture of Ardente. On the other hand, the cooked rice grains of Comparative Example 2 and the cooked rice / rice cakes of Comparative Examples 3 to 5 in which the texture of Ardente was not felt were not within the above range.

また、一般的な調理方法で製造したリゾットの比較例1は、調理直後は、米飯粒に粒感があり、且つ、アルデンテ様の歯応えがあった。しかし、上記表5より、調理直後、リゾットから取り出した米飯粒を25℃の密閉下で2時間放置した後に測定したバランス度Hは大きくなり、放置している間に、米飯粒の中心まで水分が浸透し、アルデンテ様の歯応えが失われていたことが分った。又、調理後、30分間、スープと一緒にした状態で放置しておくと、さらに、バランス度Hが大きくなり、より柔らかくなっていた。一方、実施例1は、調理後、30分間、スープと一緒に放置しても、バランス度H、バランス度A供に至適な範囲内にあったことから、本発明の容器入り即食リゾットは、調理後の喫食中の食感の劣化も抑制する効果も有している。   Moreover, the comparative example 1 of the risotto manufactured with the general cooking method had the grain feeling in the cooked rice grain immediately after cooking, and had the texture of Ardente-like. However, from Table 5 above, the degree of balance H measured immediately after cooking, after leaving the rice grains taken out from the risotto for 2 hours in a sealed state at 25 ° C., increased, and the moisture content reached the center of the rice grains while left standing. It was found that Aldente-like texture was lost. Moreover, when it was allowed to stand with the soup for 30 minutes after cooking, the balance degree H was further increased and it became softer. On the other hand, even if Example 1 was left with soup for 30 minutes after cooking, it was within the optimum range for the balance degree H and the balance degree A, so the instant food risotto in the container of the present invention is Also, it has the effect of suppressing the deterioration of the texture during eating after cooking.

<実施例8>
水を吸収させていない生米を常圧飽和蒸気で加熱処理した米34gと、水浸漬した黒豆2gと小豆2gを130mm×150mmの大きさのパウチに充填すること以外は、実施例1と同様の方法で実施して、容器入り即食リゾットを製造した。その結果、黒豆や小豆を入れることで、雑穀入りの本格的なリゾットが得られた。
<Example 8>
Same as Example 1 except that the raw rice that does not absorb water is heated with atmospheric saturated steam 34g, and 2g black beans and 2g red beans soaked in water are packed into a 130mm x 150mm pouch. In this way, a containered ready-to-eat risotto was produced. As a result, a full-fledged risotto with millet was obtained by adding black beans and red beans.
