Description

本発明は、レトルト加熱、煮込み加熱後常温で硬化せず、繰返し種々の加熱が可能で、且つ無添加の餅様食品に関するものである。   The present invention relates to a rice cake-like food that does not harden at room temperature after retort heating and simmering heating, can be repeatedly heated, and does not contain any additives.

古来より、もち(餅)は日本人に好まれている食品であるが、もち(餅)は、常温で放置したり加熱後に時間が経つと硬化する、煮込んだ際には最終的に溶けて無くなる程、著しく軟化する、等の問題を有することが知られている。即ち、餅は、一度加熱すると柔らかくなり、その後、水分の減少と共に固くなる。固くなった餅を再加熱しても、再び柔らかくなることはない。このため、そのような問題点を解消すべく、従来より、もち米(餅米)やもち粉(餅粉)を主原料とする餅様食品やその製造方法が種々、提案されている。なお、餅様食品とは、餅のような食感を有する食品全般を意味するものである。   Mochi (mochi) has been a favorite of Japanese people since ancient times, but mochi (mochi) hardens over time after standing at room temperature or after heating. It is known that there is a problem that the material becomes softer as it disappears. That is, the mochi softens once heated and then hardens with decreasing water content. Reheating the hardened rice cake will not make it soft again. Therefore, in order to solve such a problem, various types of mochi-like foods using glutinous rice (mochi rice) or glutinous rice (mochi flour) as a main raw material and methods for producing the same have been proposed. The mochi-like food means all foods having a texture like mochi.

例えば、特許文献1(特開2000−93102号公報)には、澱粉質原料に、アルカリ水溶液で溶解または膨張させたカードランを追加することを特徴とするもち類または団子類の製造方法が提案されており、また、特許文献2(特開平10−215801号公報)には、ネイティブジェランガムと餅米を含むことを特徴とする、餅様の粘弾性が持続し、かつ、耐熱性のあるゲルが提案されており、更に、特許文献3(特開平10−62号公報)には、餅米と水と混練した後、圧延されていることを特徴とする餅加工食品が提案されている。これら特許文献1〜特許文献3に開示のもち類等は、全てにおいて指定添加物が使用されている。なお、指定添加物とは、食品衛生法第10条に基づき、厚生労働大臣により定められた食品添加物である。   For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-93102) proposes a method for producing sticky or dumplings, which comprises adding curdlan dissolved or expanded with an aqueous alkali solution to a starchy raw material. Patent Document 2 (Japanese Unexamined Patent Publication No. 10-215801) discloses a gel which contains native gellan gum and rice cake rice, which maintains a rice cake-like viscoelasticity and has heat resistance. Further, Patent Document 3 (Japanese Patent Laid-Open No. 10-62) proposes a processed rice cake characterized by being kneaded with rice cake and water and then rolled. In all of the sticks and the like disclosed in Patent Literatures 1 to 3, specified additives are used. The designated additive is a food additive specified by the Minister of Health, Labor and Welfare based on Article 10 of the Food Sanitation Law.

本発明者は、先に、0〜30℃の温度域で硬化せず、且つ加熱耐性を有する餅組成物として、餅粉と小麦蛋白質を3:7〜7:3の配合割合にて含むものを提案している(特許文献4を参照)。   The present inventor has previously set a rice cake composition and a wheat protein in a mixing ratio of 3: 7 to 7: 3 as a rice cake composition that does not cure in a temperature range of 0 to 30 ° C. and has heat resistance. (See Patent Document 4).

近年、レトルト食品やチルド食品が多様化している中において、餅様食品の利用がされていないのが現状である。本発明者等は、特許文献4に開示の餅組成物について、更なる研究を進めた。その結果、同文献の餅組成物が満たす120℃×20分間の条件におけるレトルト耐性は、現在求められているレトルト耐性としては不十分であり、また、同文献に開示の餅組成物は風味、食感の点において不十分なものであり、これらの点において、同文献の餅組成物には未だ改善の余地があることが判明した。さらに、同文献に開示の餅組成物は、油を用いた調理法(油調)には不適であり、また、喫食時の加熱条件が狭いものであることも、判明したのである。   In recent years, while retort foods and chilled foods have been diversified, rice cake-like foods have not been used at present. The present inventors have further studied the rice cake composition disclosed in Patent Document 4. As a result, the retort resistance under the conditions of 120 ° C. for 20 minutes that the rice cake composition of the same document satisfies is insufficient as the currently required retort resistance, and the rice cake composition disclosed in the same document has a flavor, It was insufficient in terms of texture, and in these respects, it was found that the mochi composition of the literature still had room for improvement. Furthermore, it was also found that the mochi composition disclosed in the document is unsuitable for a cooking method using oil (oil tone), and that the heating conditions during eating are narrow.

かかる状況の下、本発明は完成されるに至ったものであり、その解決すべき課題とするところは、従来品より優れたレトルト耐性及び煮込み耐性を発揮すると共に、油調が可能であり、更には、糖類を含む溶液中において形崩れが生じ難く(以下、耐糖性に優れるという)、酸性溶液中において形崩れが生じ難く(以下、耐酸性に優れているという)、塩類を含む溶液中においても形崩れが生じ難い(以下、耐塩性に優れているという)、餅様食品を提供することにある。   Under such circumstances, the present invention has been completed, and the problem to be solved is that while exhibiting better retort resistance and stew resistance than conventional products, it is possible to adjust the oil, Furthermore, it is difficult to lose its shape in a solution containing saccharides (hereinafter, referred to as having excellent sugar resistance), hardly occurs in an acidic solution (hereinafter, referred to as having excellent acid resistance), and in a solution containing salts. The present invention also provides a rice cake-like food which does not easily lose its shape (hereinafter, referred to as having excellent salt resistance).

そして、本発明は、かかる課題を解決するために、餅粉と植物性蛋白質とが、重量比で、餅粉:植物性蛋白質=71:29〜90:10の割合において配合されてなり、且つ、水分含有量が40〜48重量%である餅様食品を、その要旨とするものである。   In order to solve the problem, the present invention comprises rice cake and vegetable protein in a weight ratio of rice cake: vegetable protein = 71: 29 to 90:10, and And a mochi-like food having a water content of 40 to 48% by weight.

なお、上記した本発明に従う餅様食品の好ましい態様においては、1)指定添加物を使用せずに、加熱後、冷蔵又は常温下において硬化せず、2)繰返し加熱が可能である。   In the above-mentioned preferred embodiment of the rice cake-like food according to the present invention, 1) without heating, without the use of the specified additives, without curing under refrigeration or at room temperature, and 2) repeated heating is possible.

このように、本発明に従う餅様食品にあっては、餅粉及び植物性蛋白質が、重量比において所定の割合において配合されたものであり、且つ、水分含有量も所定の割合に調製されたものであるところから、従来品より優れたレトルト耐性及び煮込み耐性を発揮すると共に、油調が可能であり、更には、耐糖性、耐酸性及び耐塩性にも優れたものとなっているのである。また、水分含有量を40〜48重量%の範囲内において適宜に調製することにより、本発明に係る食品の用途に応じて食感をコントロールすることが可能である。従って、本発明の餅様食品は、従来は適用することが困難とされていた惣菜レトルト食品、スイーツレトルト食品、及び通常加熱食品の惣菜やスイーツ食品にも、有利に利用可能であり、更には、鍋物素材や串揚げ等の食品素材として幅広く用いることが可能である。   Thus, in the rice cake-like food according to the present invention, the rice cake flour and the vegetable protein were blended at a predetermined ratio in weight ratio, and the water content was also adjusted to a predetermined ratio. Because it is a product, it exhibits retort resistance and stew resistance that are superior to conventional products, can be oily, and has excellent sugar resistance, acid resistance and salt resistance. . Further, by appropriately adjusting the water content within the range of 40 to 48% by weight, the texture can be controlled according to the use of the food according to the present invention. Therefore, the rice cake-like food of the present invention can be advantageously used for side dish retort foods, sweets retort foods, and normally cooked foods and sweets foods, which were conventionally considered difficult to apply. It can be widely used as a food material such as a pot material or fried skewers.

ところで、本発明に従う餅様食品を製造するに際しては、先ず、餅粉及び植物性蛋白質が準備されることとなるが、本発明において用いられる餅粉としては、餅米を製粉したものであれば、餅米の産地や種類、精製度等にかかわらず、如何なるものであっても使用することが出来る。   By the way, when producing the rice cake-like food according to the present invention, first, rice cake flour and vegetable protein are prepared, but as the rice cake flour used in the present invention, if rice cake rice is milled. Regardless of the origin and type of rice cake, the degree of refining, etc., any rice can be used.

また、本発明において用いられる植物性蛋白質にあっても、小麦や大豆等の植物を原料として、それらに含まれる蛋白質を抽出したものであれば、特に限定されることなく使用することが可能である。そのような植物性蛋白質の中でも、本発明においては、小麦やデュラムコムギ(小麦の4倍体種)、大麦、ライ麦、もち麦や押麦等から抽出される蛋白質が好ましく、より好ましくは、小麦より抽出された小麦蛋白質が用いられる。また、小麦蛋白質を使用する場合、その形態は特に限定されず、湿潤タイプのもの、粉末タイプのもの(活性グルテン)や還元グルテンの何れも使用可能である。本発明において用いられる小麦蛋白質としては、PROMAX FX75(製品名、マニルドラ社製)を例示することが出来る。   In addition, the vegetable protein used in the present invention can be used without particular limitation as long as the protein contained therein is extracted from a plant such as wheat or soybean as a raw material. is there. Among such plant proteins, in the present invention, proteins extracted from wheat, durum wheat (a tetraploid species of wheat), barley, rye, glutinous barley, oats, and the like are preferred, and more preferably wheat The extracted wheat protein is used. When wheat protein is used, its form is not particularly limited, and any of wet type, powder type (active gluten) and reduced gluten can be used. Examples of the wheat protein used in the present invention include PROMAX FX75 (product name, manufactured by Manildra).

そして、本発明に従う餅様食品にあっては、上述した餅粉及び植物性蛋白質が、重量比で餅粉:植物性蛋白質=71:29〜90:10の割合において配合されてなり、且つ、水分含有量が40〜48重量%に調製されて、構成されているところに大きな技術的特徴が存しているのである。   And in the rice cake-like food according to the present invention, the above-mentioned rice cake flour and vegetable protein are blended in a weight ratio of rice flour: vegetable protein = 71:29 to 90:10, and There is a great technical feature where the water content is adjusted to 40-48% by weight and constituted.

ここで、本発明の餅様食品において、餅粉の配合量が多すぎる場合、換言すると、餅粉及び植物性蛋白質の総量100重量部に対して、餅粉の配合量が90重量部を超える場合、植物性蛋白質の配合量が少なくなることから、得られる餅様食品が十分なレトルト耐性や煮込み耐性等を発揮し得ない恐れがある。その一方、餅粉の配合量が少なすぎる場合、換言すると、餅粉及び植物性蛋白質の総量100重量部に対して、餅粉の配合量が71重量部より少ない場合、植物性蛋白質の配合量が多くなり過ぎて、得られる餅様食品の食感が硬く、餅様の食感に乏しいものとなり、また、植物性蛋白質に由来する蛋白臭が強くなって、餅の代用品として使用し難いものとなる恐れがある。なお、本発明の餅様食品を構成する餅粉及び植物性蛋白質は、原料が天然由来のものであってバラツキがあることから、±2.5重量%以内は許容範囲とすることが出来る。   Here, in the rice cake-like food of the present invention, if the amount of the rice cake is too large, in other words, the amount of the rice cake exceeds 90 parts by weight based on 100 parts by weight of the total amount of the rice cake and the vegetable protein. In this case, since the amount of the vegetable protein is reduced, the obtained rice cake-like food may not be able to exhibit sufficient retort resistance, stew resistance and the like. On the other hand, if the amount of the rice cake is too small, in other words, if the amount of the rice cake is less than 71 parts by weight based on 100 parts by weight of the total amount of the rice cake and the vegetable protein, the amount of the vegetable protein Is too much, the resulting mochi-like food has a hard texture and poor mochi-like texture, and the protein odor derived from vegetable protein is strong, making it difficult to use as a substitute for mochi Could be a problem. The mochi flour and the vegetable protein constituting the mochi-like food of the present invention can be within an allowable range of ± 2.5% by weight because the raw materials are naturally derived and vary.

また、本発明の餅様食品において、水分含有量を40重量%未満とすると、レトルト耐性や煮込み耐性においては優れたものとなるものの、餅様の食感が乏しいものとなる恐れがあり、一方で、48重量%を超える水分含有量とすると、十分なレトルト耐性や煮込み耐性等を発揮し得ない恐れがある。   Further, in the rice cake-like food of the present invention, when the water content is less than 40% by weight, although the retort resistance and the stew resistance are excellent, the rice cake-like texture may be poor. If the water content exceeds 48% by weight, sufficient retort resistance and boiling resistance may not be exhibited.

このように、本発明に従う餅様食品は、餅粉及び植物性蛋白質が、各々、所定の割合にて配合され、且つ、水分含有量も所定の範囲内となるように調製されているところから、従来品と比べて優れたレトルト耐性及び煮込み耐性を発揮すると共に、耐糖性や耐酸性、耐塩性にも優れた餅様食品となっているのである。なお、本明細書において、レトルト耐性に優れている餅様食品とは、レトルト条件での加熱(120℃で30分間の加熱)の後においても、食品として十分な程度の形状を保持する(形崩れが生じない)ことを意味する。また、煮込み耐性に優れている餅様食品とは、沸騰水中に20分間、浸漬せしめた後においても、食品として十分な程度の形状を保持する(形崩れが生じない)ことを意味するものである。   As described above, the rice cake-like food according to the present invention is obtained by mixing rice cake flour and vegetable protein, respectively, at a predetermined ratio, and preparing the water content within a predetermined range. The rice cake-like food exhibits excellent retort resistance and stew resistance as compared with conventional products, and also has excellent sugar resistance, acid resistance and salt resistance. In this specification, a mochi-like food having excellent retort resistance means that the food retains a sufficient shape as food even after heating under retort conditions (heating at 120 ° C. for 30 minutes). (Collapse does not occur). In addition, the mochi-like food having excellent resistance to stew means that the food retains a sufficient shape as a food even after being immersed in boiling water for 20 minutes (does not lose its shape). is there.

なお、本発明の餅様食品においては、本発明の目的を阻害しない限りにおいて、各種の添加剤を配合することが可能である。例えば、従来より食品に使用されている補助剤、呈味剤、還元剤や色素等を挙げることが出来る。   In addition, in the rice cake-like food of the present invention, various additives can be blended as long as the object of the present invention is not impaired. For example, auxiliary agents, flavoring agents, reducing agents, pigments and the like conventionally used in foods can be mentioned.

本発明に従う餅様食品は、例えば、以下の手順に従って製造することが出来る。先ず、餅粉、植物性蛋白質及び水について、各々を所定量となるように秤量し、その秤量した粉体を混合し、加水しながら混練する。なお、水の量は、最終的に得られる餅様食品における固さに応じて配合される。その後、餅粉等の混合物(混練物)を成形し、食品の用途に応じてレトルト加熱処理、温水加熱処理等の加熱処理を施すことにより、目的とする餅様食品が得られるのである。   The rice cake-like food according to the present invention can be produced, for example, according to the following procedure. First, rice flour, vegetable protein and water are each weighed to a predetermined amount, and the weighed powders are mixed and kneaded while adding water. In addition, the amount of water is mixed according to the hardness of the rice cake-like food finally obtained. Thereafter, a mixture (kneaded material) such as rice cake flour is formed and subjected to a heat treatment such as a retort heat treatment or a hot water heat treatment depending on the use of the food, thereby obtaining a desired rice cake-like food.

ここで、餅粉、植物性蛋白質及び水の混合物(混練物)の加熱処理は、かかる混合物(混練物)中の植物性蛋白質を変性するための重要な工程ではあるが、例えば、レトルト商品(餅様食品のみをレトルトパックしたもの、及び餅様食品を具材として含むぜんざい等の食品をレトルトパックしたものの両者を含む)のように、商品の製造過程に加熱工程が含まれている場合には、必ずしも上記の如き加熱処理は必要ではない。従って、本明細書及び特許請求の範囲における餅様食品とは、餅粉等の混練物に加熱処理を施したものは勿論のこと、餅粉等の混練物そのものをも包含するものである。なお、上記したレトルト商品は、その製造過程において十分な加熱処理が実施されているところから、常温での保存が可能である。   Here, the heat treatment of the mixture (kneaded material) of rice flour, vegetable protein and water is an important step for denaturing the vegetable protein in the mixture (kneaded material). (Including both retort-packed mochi-like foods alone and retort-packed foods such as zenzai containing mochi-like foods as ingredients)). Does not necessarily require the heat treatment as described above. Therefore, the mochi-like food in the present description and the claims includes not only those obtained by subjecting a kneaded material such as rice cake flour to heat treatment but also those kneaded material itself such as rice cake flour. In addition, the above-mentioned retort products can be stored at room temperature since a sufficient heat treatment is performed in the manufacturing process.

また、上記した、沸騰水中に餅粉等の混合物(混練物)を浸漬せしめることによる加熱処理において、その処理時間(沸騰水中に浸漬せしめる時間)は、混練物の大きさ等によって適宜に決定されるが、一般には、1分〜20分程度の時間が採用される。尚、餅粉等の混練物に対する加熱処理の手法としては、沸騰水中への浸漬のみに限定されるものではなく、餅様食品に対する加熱処理として従来より公知の手法であれば、特に問題なく採用することが出来る。   Further, in the above-mentioned heat treatment by immersing the mixture (kneaded material) such as rice cake flour in boiling water, the processing time (time of immersing in boiling water) is appropriately determined depending on the size of the kneaded material and the like. However, generally, a time of about 1 minute to 20 minutes is employed. In addition, the method of the heat treatment for the kneaded material such as rice cake flour is not limited to only immersion in boiling water, and any method conventionally known as the heat treatment for the rice cake-like food may be used without any problem. You can do it.

さらに、本発明において、植物性蛋白質として、例えば凍結状態にあるウェットタイプのものを用いる場合には、餅粉等と混合(混練)する前に、所定温度(10〜15℃程度)に温調しながら撹拌機で撹拌し、その撹拌された植物性蛋白質を、餅粉及び水に混合することが好ましい。   Furthermore, in the present invention, when using, for example, a wet type protein in a frozen state as the vegetable protein, the temperature is adjusted to a predetermined temperature (about 10 to 15 ° C.) before mixing (kneading) with rice cake flour or the like. It is preferable to stir with a stirrer while mixing the stirred vegetable protein with rice cake flour and water.

加えて、本発明において、食感向上のために澱粉や糖類を用いる場合、それら澱粉等は、餅粉、植物性蛋白質及び水と共に混合(混練)されるのが一般的であるが、還元剤及び呈味剤を用いる場合には、先ず、植物性蛋白質を撹拌する際に還元剤を添加し、植物性蛋白質の粘度を低下させ、次いで呈味剤を添加して混練し、更にその後、餅粉及び水、必要に応じて澱粉等を添加し、混練が実施されることとなる。   In addition, in the present invention, when starch or saccharide is used for improving the texture, the starch and the like are generally mixed (kneaded) with rice cake, vegetable protein and water, but a reducing agent is used. When a flavoring agent is used, first, a reducing agent is added when stirring the vegetable protein to reduce the viscosity of the vegetable protein, then the flavoring agent is added and kneaded, and then the rice cake is further added. Powder and water, starch and the like are added as required, and kneading is performed.

以上、詳述したように、本発明に従う餅様食品にあっては、餅粉及び植物性蛋白質が、重量比において所定の割合において配合されたものであり、且つ、水分含有量も所定の割合に調製されたものであるところから、従来品より優れたレトルト耐性及び煮込み耐性を発揮すると共に、油調が可能であり、更には、優れた耐糖性、耐酸性及び耐塩性をも発揮することとなる。即ち、本発明の餅様食品は、従来品と比較して、より厳しい加熱条件下においても形崩れが発生し難いものとなっているところから、例えば、従来は適用することが困難とされていたぜんざい、汁粉、雑煮、おかゆ等のレトルト食品への利用の他、鍋物素材や、餅ピザ、串揚げ等の材料としても、その適用が期待されるものとなっているのである。   As described in detail above, in the rice cake-like food according to the present invention, rice cake flour and vegetable protein are blended at a predetermined ratio in weight ratio, and the water content is also a predetermined ratio. In addition to exhibiting superior retort resistance and stew resistance than conventional products, it can be oily, and also exhibit excellent sugar resistance, acid resistance and salt resistance. Becomes That is, since the rice cake-like food of the present invention is less likely to lose its shape even under severer heating conditions than conventional products, for example, it has been considered difficult to apply conventionally. It is expected to be used not only for retort foods such as zenzai, soup flour, zoni, rice porridge, etc., but also as a material for hot pots, mochi pizza, skewers, and the like.

以下に、本発明の実施例を幾つか示し、本発明を更に具体的に明らかにすることとするが、本発明が、そのような実施例の記載によって、何等の制約をも受けるものでないことは、言うまでもないところである。また、本発明には、以下の実施例の他にも、更には上記した具体的記述以外にも、本発明の趣旨を逸脱しない限りにおいて、当業者の知識に基づいて、種々なる変更、修正、改良等を加え得るものであることが、理解されるべきである。なお、以下に説明する本発明品及び比較品を製造するに際しては、餅粉として吉村穀粉社製の市販品を、小麦蛋白質としてマニルドラ社製の市販品(製品名:PROMAX FX75)を、各々、用いた。   Hereinafter, some examples of the present invention will be shown to clarify the present invention more specifically. However, the present invention is not limited by the description of such examples. Needless to say. Further, in addition to the following examples, the present invention may further include various changes and modifications based on the knowledge of those skilled in the art without departing from the spirit of the present invention, in addition to the specific description described above. , Improvements and the like can be added.
