Description

【0001】
【発明の属する技術分野】
本発明は鮒寿司およびその製造方法に関する。さらに詳しくは、赤米風味の鮒寿司およびその製造方法に関する。
【0002】
【従来の技術】
【特許文献1】特許第3127414号
従来の赤米を使用してなる鮒寿司は、特許文献1に記載されているように、いわゆる米飯による飯漬けを2度行なっている。つまり第1回目の米飯漬けは白米のみによる米飯にて飯漬けをする従来の製法とし、第2回目はこの白米の鮒寿司から米飯を除去した後、赤米のみによる米飯にて飯漬けにするというものである。
【0003】
【発明が解決しようとする課題】
米飯による飯漬けは発酵期を経て飯漬けが終了するのに少なくとも3〜4ケ月を要するといわれている。したがって上記従来の2度にわたる飯漬け期間は、少なくとも6ケ月以上かかることになる。さらに飯漬けは土用のころに開始して盛夏を越すことが発酵を有効にさせる上で最も有効な時期といわれている。つまりこの時期の米飯漬けは、開始後、急速かつ充分に発酵を行わせることができるのである。上記の時期に行われる米飯漬けは菌、特に乳酸菌の増加とまたこの工程で生成された有機酸などの影響によるpHの低下によって鮒寿司特有の風味が増す。さらにこれと共に腐敗細菌やポツリヌス菌などの食中毒菌の増殖が抑制されるため、同時に保存性が付与されるのである。したがって従来の赤米を使用してなる鮒寿司の飯漬けを上記の最適な環境のもとで行うならば、少なくとも二年越しになるので、長期間を要することになる。
【0004】
また2度にわたる飯漬け作業は、白米の米飯による飯漬けの米飯をわざわざ除去しなければならないこと、そして赤米の米飯を詰め直ししなければならないことによる二重手間が要されている。またその作業は非常に鮒の身が崩れ易くなってしまうので、非常にデリケートな取り扱いが必要とされる。したがって、生産効率が落ちるといった問題点がある。
【0005】
本発明は、最適な環境のもとで短時間に、かつ簡単に製造することができ、しかも赤米の風味と赤米の独特の赤色を楽しむことができる赤米風味の鮒寿司およびその製造方法を提供することを課題としている。
【0006】
【課題を解決するための手段】
本発明の鮒寿司は、塩蔵し、塩抜き処理をした鮒に、赤米と白米の混合米の米飯によって飯漬けしてなることを特徴としている(請求項1)。本発明の鮒寿司の製造方法は、鮒を塩蔵し、塩抜き処理を行ない、ついで赤米と白米の混合米の米飯によって飯漬けすることを特徴としている(請求項2)。
【0007】
前記赤米の混合比率については混合米全体の3〜50%であることが好ましい(請求項3)。さらにこのような場合、赤米の混合比率が混合米全体の5〜15%が一層好ましい(請求項4)。さらに赤米は5〜6月ごろに収穫される新米であるのがさらに好ましい(請求項5)。
【0008】
【作用および発明の効果】
本発明の鮒寿司(請求項1)は飯漬けに赤米と白米の混合米からなる米飯を用いているので、飯漬けのときに両方の米飯による作用効果が奏される。すなわち赤米は白米とは異なる栄養価や香り、風味を有するので、全体として白米の場合とは異なる風味が与えられる。また赤米はタンニン系色素を有しているので、赤米と白米を混合して炊飯した米飯(以下、赤米と白米を混合して炊飯した米飯を混合米飯という)ではそのタンニン系色素が溶出して白米の白色を赤色に変化させる。そのため混合米飯は全体的には赤みを帯びた色を呈し、また赤色の濃淡差がついたものになっている。白米によって発酵作用がすすむが、赤米にも発酵作用があるので、上記混合米飯によって、飯漬けを一度で済ませることができる。したがって赤米風味の鮒寿司を簡単に、かつ早期に製造することができる。さらに赤米のタンニンには腐敗防止の作用もあるので、鮒寿司の保存を一層良好にすることができる。
【0009】
また比較的粘り気の少ない白米と粘り気の多い赤米が一体になったことによる独特の食感および風味が得られ、さらにこれまでの単一種とは異なる濃淡色の二色を呈する米飯の趣は鮒寿司の古来の製法が現在にも息づいていることを感受させるものである。またこの鮒寿司は現代と古代のものが顕在していることによって現代から古代へとタイムスリップすることができる食品としては真骨頂である。
【0010】
本発明の鮒寿司の製造方法(請求項2)によれば、前述のような優れた作用効果を奏する鮒寿司を短時間で製造することができる。このような鮒寿司や製造法における赤米の混合比率は混合米全体の3〜50%であるのが好ましい(請求項3)。すなわち赤米の混合比率が混合米全体の3%以上であれば、白米はタンニン系色素が沈着し赤色に変化していることが外見できる。しかしそれ未満であると、白米の色の変化を認識するのが困難となる。また赤米が全体の50%までの混合米は赤米による色付けでそれ相当の赤色を白米につけることができる。したがって赤米の混合比率が混合米全体の3〜50%の範囲内の混合米飯は赤米のタンニン系色素による白米への色付けを充分に行なうことができる。
【0011】
また赤米のタンニン系色素による混合米飯の色はタンニン系色素の溶出量、あるいは赤米と白米の混合比によって濃淡差が生じる。したがって混合米飯の色はこの範囲において自由に濃淡差をつけることができる。たとえば白米を赤飯のような色からほんのりと赤く染まった色まで自由に色付けすることができ、さらにそのような色付けされた白米と濃い赤色の赤米が織り成す赤色の濃淡差を呈することも可能である。しかし、50%以上になると白米へのタンニン系色素の沈着は可能であるものの、発酵に支障がでてくる可能性がある。また鮒寿司に使用されている米飯は古来より白米によるもので、この米飯による風味こそが鮒寿司の原点である限り、この風味を根本的に変へてしまうものはどんなに美味なものであっても、それは食文化の伝統を逸脱した味となり、別の食品となる。
【0012】
前記鮒寿司の製造方法における赤米は全体の5〜15%とするのがさらに好ましい(請求項4)。つまりこの範囲にすれば、白米は赤米のタンニン系色素によってより赤く色付けされ、また白米の白色は強く赤色に変色させることができる。さらに白米の混合米全体に占める割合は大きいので、発酵は充分に行なわれるから、赤米の風味が加味された鮒寿司を得ることができる。またこの割合は白米による伝統の風味をベースに赤米の風味が加味されるので、伝統の風味を継承しているものである。
【0013】
前記赤米は5〜6月ごろに収穫される新米であるのがさらに好ましい(請求項5)。このころに収穫される赤米の新米は鮒の塩蔵が終了して飯漬けする6〜7月ごろに間に合うので、鮒寿司の発酵に必要な最高の気温環境、つまり土用のころから飯漬けを開始して盛夏を越すという環境のもとで製造することができる。したがって赤米が混在していても、発酵は充分に行なわれるので、赤米の風味を生かした最高の鮒寿司を提供することを可能にした。
【0014】
【発明の実施の形態】
つぎに図面を参照しながら本発明の実施形態を説明する。図1は本発明の鮒寿司の一実施形態を示す斜視図、図2はその鮒寿司の製造方法における飯詰めして熟成させる状態を示す斜視図、図3は本発明の鮒寿司の製造方法の一実施形態を示すフローチャートである。
【0015】
図1に示す鮒寿司10は、鮒11と、その鮒の内蔵を除いた後の空洞に詰められた混合米飯12とからなる。本発明は基本的には従来の一般的な白米を用いた鮒寿司および製法を踏襲するものであって、いわゆる飯漬けに用いる米飯が赤米と白米を混合したものを炊飯してなる混合米飯であることを特徴とするものである。この鮒寿司は図2のよう桶13内に詰め込んだ状態で熟成され、その状態で、あるいは取り分けた1匹ずつの形態で販売される。
【0016】
本発明に用いる白米は、一般の米穀店で取り扱っている自主流通米、標準価格米他、生産者が直売する産直米など各種のものを使用することができる。赤米についても一般の米穀店で取り扱っている米、産直米など各種のものを使用することができる。ただし沖縄県石垣島で5〜6月に収穫される赤米を用いるのが好ましい(図3の工程S4a参照)。また鮒は国内外を問わず天然もの、養殖もののほか塩蔵した状態で輸入されてくるニゴロ鮒、へら鮒の他、鮒寿司を製造するのに適するものであれば特に限定されるものではない。ただし伝統的な琵琶湖原産のニゴロ鮒を用いるのがもっとも好ましい(図3の工程S1参照)。
【0017】
ニゴロ鮒、へら鮒などの鮒は鱗、内臓、えら、浮き袋を除去した後、塩水で洗い、さらに真水で何度も洗って血抜きをする。そして鰓蓋の開口部から塩を腹一杯に入れた鮒を桶に詰める。このとき鮒と塩を交互に詰めて重しをする(図3の工程S2参照)。短期的な塩蔵期間は通常2〜5ケ月位である(工程S3参照)。塩蔵を終了した鮒は塩を除去して、水洗いをした後、半日ほど乾燥させる(工程S4参照)。
【0018】
次に上記の半日乾燥した鮒に混合米飯を詰めて飯漬けの準備をする。米飯は白米と赤米を混合するが、赤米の混合比率が混合米全体の3〜50%の範囲とする。ただし5〜15%がさらに好ましい。先ず赤米を洗米した後、適当な時間、水に漬け込んでいるとタンニン系色素が溶出してくる。洗米した白米は前記米タンニン系色素の溶出液にしばらく漬け込む。そして赤米と白米を混合し、先のタンニン系色素の溶出液を堅めの出来上がりになるよう釜に適当量入れて混合米を炊飯する。その他の方法としては、白米を研ぎ終えた後に赤米を入れ、適当の水と一緒に釜にいれて、炊飯する、または、混合米を同時に洗った後炊飯する、等がある。
【0019】
炊飯後の米飯は全体的には赤色を呈しているが、白米はタンニン系色素が沈着されていて、赤米の濃い赤色とは異なったこれよりは薄い赤色を呈している。外観は濃淡差のある赤色の米飯であることが認識されると共に、赤米の存在も認識される。混合米飯は少し塩をふった後、よく冷ましてからエラ蓋のところからたっぷりと腹に詰める(図3の工程S5)。混合米飯は図1のように、鰓蓋の開口から盛り上がる程度に詰め込む。混合米飯を詰めた鮒は桶の中に順に詰めて重しをする(図3の工程S6)。つけ込む時期は特に制限はないが、土用の時期が好ましい。その場合、飯付けによる発酵が進む時期(図3の工程S7)が盛夏の時期となり、発酵が急激にすすみ、悪性の菌が発生しない。飯漬けは短期間の場合、3〜4ケ月で飯浸けが完了することができる(図3の工程S8)。
【0020】
以上のようにして製造した鮒寿司は、混合米飯が飯漬けのときに充分、発酵することができる。したがって、従来の赤米を使用してなる鮒寿司が白米と赤米を別々に飯漬けするに要する時間は不要になったので、短期に製造することが可能になった。また混合米飯による飯漬けは単独の米飯漬けよりも風味と旨みが増した。
【0021】
従来の赤米のタンニンに関する知見、すなわちタンニンには発酵製品のタンパクを除去する作用を有し、また、タンニンを含むポリフェノールが酵母などの発酵のための微生物の増殖に影響を及ぼすと言われているが、このことから推察するに、白米に代えて赤米を使用した飯漬けは鮒寿司の発酵が急速且つ十分でなく、また、成分中に含まれているタンパクに大きく影響するので、鮒寿司特有の風味、香りが得られなかったものと考えられる。しかし白米との混合米飯とすることによって、赤米の持つ特有の香りを鮒寿司に生かすことができたものと考えられる。そして赤米のタンニン系色素を白米に添加させることができたことによって、米飯の色を赤系にすることができたので、白米のイメージを消すことが可能になった。したがって、赤米風味の鮒寿司を混合米飯を使用することで短期間で製造可能とし、飯漬けの作業中に鮒が損なわれることが防止された。
【0022】
【実施例】
つぎに具体的な実施例をあげて本発明を説明する。鮒はニゴロ鮒(滋賀県、琵琶湖の固有種)が最も美味であると賞賛され、また珍重されている。このニゴロ鮒は毎年4月から6月の間に産卵期を迎えるが、本実施例では産卵前の4月に捕獲したものを10Kg用意し、また塩を10Kg用意して、鮒の腹に塩を詰め込み、また表面に振りかけたりして桶にこれらを入れ、この上から蓋をして重しを置いた。塩蔵期間は3ケ月間、つまり7月で塩蔵は終了した。塩蔵終了後は鮒を水洗いし、半日乾燥した。
【0023】
また赤米の新米としては、上記塩蔵が終了する前の6月に収穫された沖縄県石垣島産の赤米の新米1.5Kgを用いた。また白米については前年に収穫された滋賀県産のコシヒカリを13.5Kg使用し、赤米と白米の割合は1:9とした。赤米および白米は前記実施形態で記述した第2番目の洗米方法にて洗米して炊飯する。混合米飯を鮒のエラ部から腹部に詰め込んだり,鮒と鮒の間に介在させたりして前記と同じ大きさの樽に漬け込む。飯漬けは7月の土用のころに開始し、盛夏を越えて行なわれ10月に終了した。飯漬けの作業においては、漬け込み開始後から各種微生物が増加、特に乳酸菌の増加が著しくさせることができたものと考えられる。また土用のころに漬け込みを開始して盛夏を越すことで充分に発酵されたものと考えられる。
【0024】
この実施例の白米と赤米の混合米飯による鮒寿司は鮒の骨の軟らかさ、肉質、香り、酸味など鮒寿司独特の風味を有すると共に赤米による風味が加味されて、白米だけによる鮒寿司のものよりも美味な味を呈した。また混合米飯による食感はこれまでの白米のみによる飯浸けの鮒寿司および特許文献1に記載されている赤米のみによる飯漬けの鮒寿司のものとは異なり、従来の白米のみの米飯による適度なやわらかさの中に適度な歯ごたえがあり、格別の食感を呈することができた。外観については、特許文献1に記載されている赤米による単一色とは異なり、濃淡差がついた赤色の米飯であるから、装飾性があってユニークな鮒寿司を提供することができた。
【0025】
本実施例では鮒の捕獲から飯漬けが完了するまでに6ケ月という短期間で赤米風味の鮒寿司を製造することができた。したがって特許文献1のように2度にわたる飯漬けのリスクは一切ない。またこの文献にはない古来の鮒寿司の伝統的な食感、つまり白米による食感を可及的維持しながら赤米の風味を加味することができた。そして外観は特許文献1のような単一の色とは異なり、濃淡差のある赤色で美的印象のある鮒寿司となった。さらに古代より受け継がれてきた鮒寿司の食文化を赤米の使用で古代におもいを馳せるロマンティズムを潜在させることもできた。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to crucian carp sushi and a method for producing the same. More specifically, the present invention relates to red rice flavored crucian carp sushi and a method for producing the same.
[0002]
[Prior art]
[Patent Literature 1] Japanese Patent No. 3127414 As described in Patent Literature 1, Funa sushi made using red rice in the related art performs twice so-called rice pickling with cooked rice. In other words, the first method of pickling rice is a conventional method of pickling rice with only white rice, and the second is removing rice from this white rice crucian sushi and then pickling rice with only red rice That is.
[0003]
[Problems to be solved by the invention]
It is said that it takes at least 3 to 4 months for rice pickling to be completed after the fermentation period. Therefore, the conventional two-time pickling period takes at least six months or more. In addition, it is said that rice pickling is the most effective time to start fermentation and to go through the midsummer to make fermentation effective. In other words, rice pickles at this time can be rapidly and sufficiently fermented after the start. The rice pickles performed during the above period increase the unique flavor of Funa Sushi due to an increase in bacteria, especially lactic acid bacteria, and a decrease in pH due to the effects of organic acids and the like generated in this process. In addition, the growth of food poisoning bacteria such as spoilage bacteria and P. botulinum is suppressed, and at the same time, preservability is imparted. Therefore, if pickled crucian carp sushi made with conventional red rice is performed in the above-described optimum environment, it will take at least two years, which will take a long time.
[0004]
In addition, the rice pickling operation for two times requires double labor because it is necessary to remove the rice pickled by the white rice and to repack the red rice. In addition, the work requires the delicate handling of the crucian carp, since it is very easy to collapse. Therefore, there is a problem that production efficiency is reduced.
[0005]
The present invention relates to a red rice flavored crucian sushi that can be manufactured in a short time and easily under an optimal environment, and that can enjoy the flavor of red rice and the unique red color of red rice. The task is to provide a method.
[0006]
[Means for Solving the Problems]
The crucian carp sushi of the present invention is characterized in that crucian carp, which has been salted and desalted, is pickled with mixed rice of red rice and white rice (claim 1). The method for producing crucian carp sushi of the present invention is characterized in that crucian carp is salted, desalted, and then pickled with mixed rice of red rice and white rice (claim 2).
[0007]
The mixing ratio of the red rice is preferably 3 to 50% of the whole mixed rice (claim 3). Further, in such a case, the mixing ratio of red rice is more preferably 5 to 15% of the whole mixed rice (claim 4). More preferably, the red rice is a new rice harvested around May or June (claim 5).
[0008]
[Action and effect of the invention]
Since the crucian carp sushi (Claim 1) of the present invention uses cooked rice made of a mixture of red rice and white rice for pickled rice, the effects of both cooked rice are exhibited when pickled. That is, red rice has a different nutritional value, aroma, and flavor from white rice, and therefore, as a whole, a flavor different from that of white rice is given. In addition, red rice has a tannin pigment, so in cooked rice cooked by mixing red rice and white rice (hereinafter, rice cooked by mixing red rice and white rice is called mixed cooked rice), the tannin pigment is It elutes and changes the white color of white rice to red. Therefore, the mixed cooked rice has a reddish color as a whole, and has a different shade of red. Although the fermentation action is promoted by the white rice, the red rice also has the fermentation action. Therefore, funerushi sushi with red rice flavor can be easily and early manufactured. Further, the tannins of red rice also have an effect of preventing rot, so that the preservation of crucian carp sushi can be further improved.
[0009]
In addition, a unique texture and flavor can be obtained by integrating white rice with relatively low stickiness and red rice with high stickiness, and the taste of cooked rice that has two shades of light and shade different from the conventional single rice is It is a reminder that the ancient method of making crucian carp sushi is still alive today. Also, this crucian carp sushi is a true value as a food that can be time-slid from modern to ancient times due to the fact that modern and ancient ones are manifested.
[0010]
According to the method for producing crucian carp sushi of the present invention (claim 2), crucian carp sushi having the above-described excellent effects can be produced in a short time. It is preferable that the mixing ratio of red rice in such a crucian carp sushi or production method is 3 to 50% of the whole mixed rice (claim 3). That is, when the mixing ratio of red rice is 3% or more of the whole mixed rice, it can be seen that tannin-based pigment is deposited on the white rice and the white rice is changed to red. However, if it is less than that, it is difficult to recognize the change in the color of the white rice. In addition, red rice up to 50% of the total mixed rice can be colored with red rice to give a corresponding red to white rice. Therefore, in the mixed cooked rice in which the mixing ratio of red rice is in the range of 3 to 50% of the whole mixed rice, it is possible to sufficiently color red rice with tannin-based pigment.
[0011]
Further, the color of the mixed cooked rice due to the tannin-based pigment of red rice varies depending on the amount of the tannin-based pigment eluted or the mixing ratio of red rice and white rice. Therefore, the color of the mixed cooked rice can be freely differentiated in this range. For example, you can freely color white rice from reddish rice to a slightly reddish color, and it is also possible to show the difference in shades of red that such colored white rice and dark red red rice weave is there. However, when the content exceeds 50%, although tannin-based pigments can be deposited on white rice, fermentation may be hindered. Rice cooked in crucian sushi has been made from white rice since ancient times, and as long as the flavor of this cooked rice is the origin of crucian sushi, it is just how delicious this flavor can be changed. Even, it becomes a taste that deviates from the tradition of food culture and becomes another food.
[0012]
More preferably, red rice in the method for producing crucian carp sushi is 5 to 15% of the whole (Claim 4). In other words, in this range, white rice is colored more red by the tannin pigment of red rice, and white of white rice can be strongly discolored to red. Further, since the ratio of white rice to the total mixed rice is large, fermentation is sufficiently performed, so that crucian carp sushi with flavor of red rice can be obtained. In addition, this ratio is based on the traditional flavor of white rice and the flavor of red rice is added, so that the traditional flavor is inherited.
[0013]
More preferably, the red rice is fresh rice harvested around May or June (Claim 5). The red rice, which is harvested at this time, is in time for June to July, when the salting of the crucian is finished and pickled, so the highest temperature environment required for fermentation of the crucian sushi, that is, pickled from the earth It can be manufactured in an environment where the summer begins and the summer is over. Therefore, even if red rice is mixed, fermentation is sufficiently performed, so that it is possible to provide the best crucian carp sushi utilizing the flavor of red rice.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the crucian carp sushi of the present invention, FIG. 2 is a perspective view showing a state where the crucian carp is cooked and aged in the method for producing the crucian carp sushi, and FIG. 5 is a flowchart illustrating an embodiment of the present invention.
[0015]
A crucian carp sushi 10 shown in FIG. 1 comprises a crucian carp 11 and mixed rice cooked in a cavity after removing the crucian carp. The present invention basically follows a conventional general-use white rice made of crucian carp sushi and a manufacturing method, in which the rice used for so-called pickled rice is prepared by cooking a mixture of red rice and white rice. It is characterized by being. This Funa sushi is aged in a state of being packed in a tub 13 as shown in FIG. 2, and is sold in that state or in a form of one by one.
[0016]
As the white rice used in the present invention, various types of rice such as voluntary rice, standard-price rice, and directly produced rice sold directly by producers can be used. Various types of red rice can be used, such as rice that is handled at general grain stores and straight rice. However, it is preferable to use red rice harvested from May to June in Ishigaki Island, Okinawa Prefecture (see step S4a in FIG. 3). The crucian carp is not particularly limited as long as it is suitable for producing crucian carp sushi, as well as natural and cultured fish, domestically and abroad, as well as Nigoro crucian and spatula crucible imported in a salted state. However, it is most preferable to use traditional Nigoro crucian carp native to Lake Biwa (see step S1 in FIG. 3).
[0017]
After removing scales, internal organs, gills, and blisters, crucibles such as Nigoro-Funa and Hera-Funa are washed with salt water, washed several times with fresh water to remove blood. Then, crucibles filled with salt are filled into the tub from the opening of the gill lid. At this time, crucibles and salt are packed alternately and weighed (see step S2 in FIG. 3). The short-term salting period is usually about 2 to 5 months (see step S3). After the salting, the crucian carp is removed from the salt, washed with water, and dried for about half a day (see step S4).
[0018]
Next, the half-day dried crucian carp is filled with mixed cooked rice to prepare rice pickles. Cooked rice mixes white rice and red rice, and the mixing ratio of red rice is in the range of 3 to 50% of the total mixed rice. However, 5 to 15% is more preferable. First, after washing the red rice, if it is soaked in water for an appropriate time, the tannin-based dye will elute. The washed white rice is soaked in the eluate of the rice tannin pigment for a while. Then, red rice and white rice are mixed, and an appropriate amount of the eluate of the tannin-based pigment is placed in a kettle so as to obtain a firm finish, and the mixed rice is cooked. As another method, there is a method in which red rice is put after finishing polishing white rice, put in a pot with appropriate water and cooked, or cooked after washing mixed rice at the same time.
[0019]
Cooked rice has a red color as a whole, but white rice has a tannin-based pigment deposited thereon and has a lighter red color than the dark red color of red rice. It is recognized that the appearance is red rice with different shades, and the presence of red rice is also recognized. After the mixed cooked rice is slightly salted and cooled sufficiently, the rice is fully packed in the belly from the gill lid (step S5 in FIG. 3). As shown in FIG. 1, the mixed cooked rice is packed so that it rises from the opening of the gill lid. The crucian carp packed with mixed rice is stuffed in a tub in order and weighed (step S6 in FIG. 3). There is no particular limitation on the timing of applying, but it is preferable to use the soil. In this case, the time when fermentation by rice cooking proceeds (step S7 in FIG. 3) is the midsummer time, and the fermentation proceeds rapidly and no malignant bacteria are generated. In the case of short-term pickling, the pickling can be completed in 3 to 4 months (step S8 in FIG. 3).
[0020]
The crucian carp sushi produced as described above can be sufficiently fermented when the mixed cooked rice is pickled. Therefore, the time required for traditional crucible sushi using red rice to separately pickle white rice and red rice is no longer necessary, so that it is possible to produce the rice in a short period of time. In addition, rice pickles with mixed rice were more flavorful and umami than single rice pickles.
[0021]
Conventional knowledge of tannins in red rice, that is, tannins have the effect of removing proteins from fermented products, and it is said that polyphenols containing tannins affect the growth of microorganisms for fermentation such as yeast. However, it can be inferred from this that rice pickles using red rice instead of white rice do not rapidly and sufficiently ferment sushi and also greatly affect the protein contained in the ingredients. It is probable that the flavor and aroma peculiar to sushi were not obtained. However, it is thought that the unique aroma of red rice could be utilized in crucian carp sushi by using mixed rice with white rice. By adding the tannin-based pigment of red rice to white rice, the color of cooked rice could be changed to red, so that the image of white rice could be erased. Therefore, it was possible to produce red rice flavored crucian carp sushi in a short period of time by using mixed rice, thereby preventing damage to crucian carp during pickling.

Next, the present invention will be described with reference to specific examples. The crucian carp is praised for being the most delicious, and it is also prized as Nigoro crucian (an endemic species of Lake Biwa, Shiga Prefecture). This nigoro crucian enters the spawning season between April and June every year. In this example, 10 kg of the fish caught in April before laying eggs and 10 kg of salt were prepared, and salt was placed on the belly of the crucian. Stuffed and sprinkled on the surface, put them in the tub, covered it with a lid and put a weight. The salting period ended in three months, that is, in July. After salting, the crucian was washed with water and dried for half a day.
[0023]
As fresh red rice, 1.5 kg of fresh red rice from Ishigaki-jima, Okinawa, which was harvested in June before the completion of the salting. For white rice, 13.5 Kg of Koshihikari from Shiga harvested in the previous year was used, and the ratio of red rice to white rice was 1: 9. Red rice and white rice are washed and cooked by the second rice washing method described in the above embodiment. The mixed cooked rice is stuffed into the barrel of the same size as the crucible from the gill part of the crucian or packed between the crucian and the crucian. Izuke started in the middle of July in the middle of mid-season, and was over mid-summer and ended in October. It is considered that in the operation of pickling rice, the number of various microorganisms increased, especially the increase of lactic acid bacteria, after the start of the pickling. It is considered that the fermentation was sufficiently fermented by starting pickling in the soil for the mid-summer and passing through the midsummer.

The crucian carp sushi made of mixed rice of white and red rice of this embodiment has the unique flavor of crucian carp, such as tenderness, meat quality, aroma, and sourness of crucian carp, and the flavor of red rice is added, and the crucian carp sushi only made of white rice Tasted better than that of In addition, the texture of the mixed rice is different from that of the traditional rice-soaked crucian sushi made of only white rice, and the traditional rice-cooked crucian sushi only of red rice described in Patent Document 1. There was moderate chewyness in the softness, and a special texture was able to be exhibited. Regarding the appearance, unlike the single color of red rice described in Patent Document 1, it is a red cooked rice with different shades, so that a unique decorative crucian sushi can be provided.
[0025]
In this example, red rice-flavored crucian sushi was able to be produced in a short period of six months from the capture of crucian to the completion of pickling. Therefore, there is no risk of pickling rice twice as in Patent Document 1. In addition, it was possible to add the flavor of red rice while maintaining as much as possible the traditional texture of ancient crucian sushi that is not described in this document, that is, the texture of white rice. The appearance was different from a single color as disclosed in Patent Document 1, and it became a beautifully colored crucian sushi with different shades of red. Furthermore, the use of red rice in the food culture of crucian carp sushi, which has been passed down since ancient times, could have a potential for romanticism in ancient times.
