Description

【0001】
【発明の属する技術分野】
本発明は、小麦粉に対し、コラーゲンペプチド及び低吸湿性増粘多糖類を含有する即席熱風乾燥麺の製造方法に関するものである。
【0002】
【従来の技術】
従来から即席麺の乾燥方法は、油揚げと非油揚げの乾燥方法がある。非油揚げ乾燥方法は一般的には、熱風乾燥やマイクロ波乾燥、フリーズドライ、寒干し乾燥等の乾燥方法が知られている。原料には小麦粉、各種澱粉を用い、中華麺においてはかんすいを、和風麺においてはかんすいに代えて重合リン酸塩等を使用し、必要に応じて食塩、粉末卵、増粘多糖類、油脂類、レシチン、その他を添加し混捏後に製麺し、蒸煮後に所定の乾燥方法により油揚げ麺及び非油揚げ麺(ノンフライ麺)が得られる。
【0003】
また、これらの即席麺類の喫食方法としては、鍋で煮込み調理するタイプと熱湯を注加して調理するタイプの2つに大別される。鍋で煮込み調理するタイプは、調理時の熱量が大きいために麺線内部まで速やかに熱湯がゆき渡り、十分に澱粉粒子を膨潤できるために、比較的弾力のある食感を実現できる。しかし、油揚げ麺及び非油揚げ麺の熱湯を注加して調理するタイプ(以下にスナック麺と云う)は、調理時の熱量が明らかに少いため、麺線内部への熱湯到達時間が長くなってしまい、麺線内部の澱粉粒子が速やかに膨潤することができないために、麺線を平麺にしかつ薄く加工しないと、戻り硬い食感になってしまう。
【0004】
近年では、消費者による本格派志向の流れが強くなっており、即席麺類、とりわけ非油揚げ乾燥麺のスナック麺については、「生麺のような粘弾性」を有し、かつ「生麺のようなみずみずしい食感」を実現することが望まれている。
【0005】
低温熱風乾燥方法は乾燥温度が100℃未満の熱風のため、麺線の水分を徐々に乾燥をすることができるため、麺の構造は気泡の無い緻密なものとなる。そのため、比較的弾力性のある食感を再現することができるが、麺線の構造が緻密なために喫食時に麺線内部まで水分が浸透し難い欠点がある。
【0006】
そこで、従来から低温熱風乾燥方法では、麺線の復元性を高めるために、小麦粉に対し各種澱粉の割合を高める方法が採られている。しかし、澱粉の添加量が過度に多いと復元性は向上し、みずみずしさのある食感になるが、小麦本来の粘りのある食感が薄れ、澱粉食感が強くなり、「生麺のような粘弾性」には程遠いものとなってしまう。
【0007】
低温熱風乾燥方法の欠点を解消するために考案された高温熱風乾燥方法は、乾燥温度が100℃以上、熱風の風速も10m/秒前後のため、水の沸点よりも高い温度で急速に脱水乾燥するので、麺の外観は乾燥により発泡した状態となり、麺の構造は油揚げ麺と同様なポーラスなものとなり、生麺様のボリュームのある麺線を得ることができる。しかし、その食感はポーラスな構造のために、食べ応えの無いスカスカとしたものとなり、「生麺のような粘弾性」を実現することはできない。
【0008】
更には、即席高温熱風乾燥方法によって造られた乾燥麺は、造りたての食感と日をおいてからの食感の差、所謂経時変化が大きいという問題点があり、とりわけ熱湯を注加して調理するスナック麺タイプでこの経時変化が顕著である。具体的には、造りたての食感がみずみずしく粘弾性に優れた食感でも、日が経つにつれて、麺線のみずみずしさが失われ、粘弾性の無いボソボソとした食感となってしまう傾向が強い。
【0009】
上述した食感の経時変化の原因としては、小麦粉中の澱粉又は添加した澱粉の老化、乾燥直後の麺線中の水分分布が時間と共に変化、つまり水分勾配を起こすことなどが考えられる。
【0010】
澱粉の老化はその性質上、十分な水分を与えて糊化することで遅らせることが可能であると分っている。即ち、即席熱風乾燥麺においてα化処理を行う以前に、十分な水分を麺線に与え、澱粉を十分に膨潤、崩壊させることで澱粉の老化を防止することができる。しかし、一般の即席熱風乾燥麺は生産性及び経済性などから、麺線に対する水分率は40%前後が限界である。
【0011】
ここで、即席熱風乾燥麺において、現在まで、麺線に十分な水分を与え糊化する方法として幾つかの方法が開示されている。特許文献1には、麺線を60℃〜100℃の湯に浸漬等の処理を行い、麺線を蒸煮する方法が開示されている。この方法によれば、確かに常法よりも麺線を糊化膨潤することができるが、本発明者が実験を行ったところ、食感の経時変化を十分に抑制することはできなかった。
【0012】
また、特許文献2には、麺線を塩濃度20%(W/V)から飽和濃度の塩溶液で茹で処理し、その後に冷水で麺線を洗う工程が開示されている。確かに、蒸煮処理よりも湯で処理した方が、麺線中の澱粉に十分な水分を与え糊化することができるが、麺線の塩味が強くなってしまい、更には製造工程が複雑になり、排水処理問題等があり、経済性に問題点がある。

【発明が解決しようとする課題】
即席熱風乾燥麺、特に高温熱風乾燥方法において、食感の経時変化を抑制し、「生麺のような粘弾性」を有し、かつ「生麺のようなみずみずしい食感」を実現することのできる即席熱風乾燥麺の製造方法を見い出すことを目的として、本発明者は鋭意研究し、生産性及び経済性を両立しながら、食感の経時変化を改善するため、澱粉の老化防止効果が優れ、かつ保水力の強い性質を持つコラーゲンペプチドを麺原料に添加し実験を行った。
【0015】
コラーゲンペプチドを麺に添加する方法としては、特許文献3に穀類食品に対し分子量1000から10000のコラーゲンペプチドを添加することとから成る穀類食品の改質方法が開示されているが、この方法は単にコラーゲンペプチドを練りこむことを示したものであり、本発明者が実験したところ、コラーゲンペプチドを単一で添加しても、経時変化を完全には抑制することには至らなかった。
【0016】
【特許文献3】
特開昭54−10619号公報
【0017】
本発明の目的は、上述の問題点を解消し、食感の経時変化を抑制し、生麺のような粘弾性を有し、かつ生麺のようなみずみずしい食感を実現することのできる即席熱風乾燥麺の製造方法を提供することにある。
【0018】
【課題を解決するための手段】
上記目的を達成するための本発明に係る即席熱風乾燥麺の製造方法は、小麦粉に対しコラーゲンペプチド及び低吸湿性増粘多糖類を混合した麺原料と水を混捏して麺塊を作成する第1工程と、前記麺塊を製麺する第2工程と、製麺した麺線を蒸煮する第3工程と、蒸煮した前記麺線を熱風乾燥する第4工程とから成ることを特徴とする。
【0019】
【発明の実施の形態】
本発明を図示の実施の形態に基づいて詳細に説明する。
本実施の形態においては、図1に示すように先ず第1工程として、小麦粉に対しコラーゲンペプチド及び低吸湿性増粘多糖類を含有する麺原料と水を混捏して麺塊を作成する。次に、第2工程としてドウを製麺し、第3工程として麺線を蒸煮し、第4工程として麺線を熱風乾燥する。
【0020】
本実施の形態に用いるコラーゲンペプチドの製造方法は特に限定しないが、コラーゲンペプチドとは、動物の骨、皮等から得られるコラーゲンと呼ばれる蛋白質を酵素により加水分解し、低分子化した蛋白質である。同様に、コラーゲンから製造されるゼラチンが、分子量数万〜30万のゲル化能のある冷水には溶けない蛋白質に対し、コラーゲンペプチドは分子量千〜数万のゲル化能の無い冷水可溶の蛋白質である。
【0021】
一般的には、コラーゲンからゼラチンを製造し、ゼラチンからコラーゲンペプチドを製造する。このため、コラーゲンからゼラチンを製造する際に、コラーゲンを含む原料をアルカリ又は酸処理するため、コラーゲンペプチドは等イオン点の異なる2種類が存在する。アルカリ処理を行ったものは等イオン点6〜9、酸処理を行ったものは等イオン点4〜5となるが、本実施の形態では特に等イオン点は限定しない。
【0022】
本実施の形態において使用するコラーゲンペプチドは、分子量が1000〜5000のものが好ましい。具体的には、新田ゼラチン株式会社SCP―3100(分子量3000)、新田ゼラチン株式会社SCP―5100(分子量5000)、新田ゼラチン株式会社LCP微粉(分子量2000)、宮城化学工業株式会社CPB−5(分子量5000)等がある。
【0023】
分子量が5000を超えると、蛋白質としての性質が強く出てきてしまい、食感が好ましくなくなり、更にはコラーゲン特有の獣臭が気になる。また、分子量1000以下はコラーゲンペプチドとしての性質が薄れて効果が得られず、更にはアミノ酸の性質が強く出てしまい、風味が優れない。
【0024】
コラーゲンペプチドの添加量は、小麦粉に対して0.1〜2%、好ましくは0.2〜1%とすると良い。コラーゲンペプチドの添加量が少ないと、その効果が得られず、また2%を超えると、麺線のべたつき、製造性の低下が生じ、更には食感が良くない。
【0025】
本実施の形態における低吸湿性増粘多糖類とは、増粘多糖類において水分の少ない状態において、物質そのものが水分を引き寄せる性質の低いものを示す。水分の多い状態、即ち水溶液中などにおける水分の吸収力とは、その意味が異なる性質を示している。吸湿性が極端に高い増粘多糖類を使用すると、澱粉の抱えている水分を激しく吸水してしまうために、かえって澱粉の老化を引き起こし易くさせてしまい、経時変化を引き起こす。
【0026】
低吸湿性増粘多糖類としては、具体的にはペクチン、アルギン酸、タマリンド種子、タラガム、グァーガム、カラギーナン、プルラン、アラビアガムなどであり、特に好ましくは、ペクチン、アルギン酸、タマリンド種子、タラガム、グァーガムである。これら、低吸湿性増粘多糖類を使用することで、増粘多糖類の一般的な性質である保水力及び増粘性により、澱粉粒の離水を効果的に防止することができ、更にはコラーゲンペプチドとの相乗効果により、食感の経時変化を抑制することができる。
【0027】
低吸湿性増粘多糖類の添加量としては、増粘多糖類の種類にもよるが、小麦粉に対して0.01〜1%、好ましくは0.05〜0.5%添加すると良い。添加量が多すぎると、食感硬くなりすぎるなどの弊害が生じ、少ないと効果が得られない。
【0028】
図2は増粘多糖類の吸湿性を明確にするための増粘多糖類の吸湿性試験の結果を示している。試験方法は重量既知のプラスチックシャーレに各増粘多糖類サンプルを正確に10.00g秤量する。インキュベータ(温度35℃、湿度72%)に静置し(オープン)、経時的に重量を測定し、次式により吸収率を求めた。
吸湿率(%)=(静置後重量−初発重量)/初発重量×100
【0029】
この図2から増粘多糖類の種類により、吸湿性の差があることが分かる。大豆多糖類、キサンタンガムなどは吸湿性が高いために、保水力は高いが経時変化を抑制することはできない。また、ペクチン、アルギン酸、タマリンド種子、タラガム、グァーガムなどは、吸湿性が比較的低いことが分かる。このような低吸湿性増粘多糖類をコラーゲンペプチドと併用することで、澱粉の離水及び老化を防ぎ、食感の経時変化を抑制することができる。
【0030】
また、コラーゲンペプチドと低吸湿性増粘多糖類の相乗効果を明らかにするために、コラーゲンペプチド(分子量3000)と、ペクチンをそれぞれ使用、不使用とし、即席熱風乾燥麺において長期保存試験を行った。試験方法は、後述する実施例1に基づいて行った。表1はその食感の評価を示している。
【0031】

Figure 2004344081
【0032】
この表1の結果から、コラーゲンペプチド又は低吸湿性増粘多糖類であるペクチン単独の添加では、食感の経時変化を抑制することができず、また得られる麺線の粘弾性及びみずみずしさも劣ることが分かる。即ち、コラーゲンペプチドと低吸湿性増粘多糖類であるペクチンを合わせて添加することで、食感の経時変化を抑制し、かつ食感に優れる即席熱風乾燥麺を得ることができる。
【0033】
本実施の形態における即席熱風乾燥麺とは、その種類及び製品形態に特に限定されず、例えば中華麺、うどん、そば等の煮込みタイプ、熱湯を注加して調理するタイプであり、特に熱湯を注加して調理するタイプである即席高温熱風乾燥麺において、その製造適性、食感改良が有効である。
【0034】
本実施の形態がその対象とする即席熱風乾燥麺は、主原料である小麦粉に分子量1000〜5000のコラーゲンペプチド及び低湿性増粘多糖類を配合し、必要に応じて澱粉、食塩、かんすいの副原料を添加し、混捏し、複合製麺後に、切刃により麺線を切り出して生麺線とし、これを連続的に蒸した後に、乾燥用バスケットに1食ずつ成形充填する。その後に、必要により着味液や、乳化剤、油脂、大豆多糖類等のほぐし剤等を麺線表面に付着させ、熱風乾燥処理することにより、目的とする麺線を得ることができる。
【0035】
また、このときの第1工程の混捏方法として、従来から周知の装置によって常圧下又は減圧下で実施すればよく、後者では真空ミキサなどを使用することができる。真空ミキサを使うことで、混捏時にグルテンを効率良く生成することができるために「生麺のような粘弾性」の効果が助長される。第4工程の熱風乾燥工程としては、80〜160℃の温度に調整された乾燥機内を10分〜80分通過させ、麺線の水分が10%前後になるように乾燥すればよい。
【0036】
ここで、本実施の形態が特にその効果を発揮する即席高温熱風乾燥麺の製造方法を示すが、その効果がその乾燥方法に基づいて限定的に解釈されるわけではない。即席高温熱風乾燥麺は通常では麺線の急激な発泡を防ぐため、麺線の水分を15〜25%に調整する予備乾燥と、予備乾燥された麺線を発泡乾燥させる本乾燥の2つの工程に大きく分けることができる。
【0037】
予備乾燥工程では麺線を温度80〜115℃(好ましくは95〜105℃)、風速1〜10m/秒(好ましくは3〜5m/秒)に調整された熱風により、麺塊の水分を15〜25%に調整しておくことで、高温高速熱風による本乾燥時に麺線中心部分を速やかに効率良く乾燥することができ、急激な発泡を防ぐことができる。
【0038】
麺塊の水分が25%以上であると、本乾燥時に麺線の急激な発泡を防ぐことができず、均一な発泡を行うことができないので、麺線内部において大きな空洞や麺線の割れを起こしてしまう。また、水分が15%以下であると、本乾燥において麺線の発泡が起こり難い。温度が80℃以下であると乾燥効率が悪く、乾燥時間が長くなってしまい、115℃以上であると乾燥が徐々にできなくなり、麺線の発泡が始まってしまい、均一は発泡麺を得ることができない。また、風速が1m/秒以下であると麺塊中を通気できず、予備乾燥にむらを生じてしまい、10m/秒以上であると麺塊が型枠の上部又は下部に押し付けられ、結果麺塊が粗の状態にならず均一な予備乾燥ができずに、乾燥むらを生じ、喫食時の麺線のほぐれも悪くなってしまう。
【0039】
本乾燥段階では、温度110〜145℃(好ましくは115〜135℃)、風速5〜25m/秒(好ましくは8〜20m/秒)に調整された熱風により麺線を乾燥させる。その所要時間としては、2〜4分間乾燥させ、麺中の水分を7〜14%にしながら麺線を発泡乾燥する。
【0040】
この本乾燥工程は、高温、高速の熱風により一気に麺中の水分を蒸発する工程であり、その急激な蒸発により麺の発泡状態を形成させる。ここで、温度が110℃以下であると発泡が生ぜず、145℃以上であると部分的に麺線に焦げを生じ商品価値を損う。また、風速が5m/秒以下であると、乾燥効率が悪く、25m/秒以上であると、工業的に見て不要なエネルギをかけることになる。
【0041】
次に、本実施の形態の効果について、次に実施例を挙げて具体的に説明する。
【0042】
[実施例1] コラーゲンペプチドを添加して製造した麺類について、分子量の違いによる効果を示すために、幾つかのコラーゲンペプチドを次のように用いて比較試験をした。
【0043】
小麦粉800g、タピオカ澱粉200g、かんすい3g、食塩10gに表2の分子量を持つコラーゲンペプチド又は水溶性ゼラチン又はゼラチンを、それぞれ5g及びペクチン3gを配合した麺塊に320mlの加水量で混捏し、製麺した後に、切刃:18丸、麺厚:1.20mmで切り出し、連続的に0.5kg/cmで3分間蒸煮した後に、麺重115gに裁断した蒸し麺を乾燥用型枠に充填した。その後、温度100℃、風速4m/秒に調整してある予備乾燥段階を3分間実施し、水分を24%に調整した後に、温度120℃、風速10m/秒に調整した乾燥機内で2分間乾燥させ、最終水分8%の熱湯注加タイプの即席中華麺を得た。食感評価を次の表2のコラーゲンペプチドの分子量による食味、食感の比較に示す。
【0044】
Figure 2004344081
【0045】
この表2の結果より、コラーゲンペプチドの分子量が5000を超えてしまうと食味、食感が優れなくなることが分かる。即ち、1000〜5000の分子量を持つコラーゲンペプチドを用いた場合に、良好な即席熱風乾燥麺を製造できる。
【0046】

【0051】
[実施例5] 小麦粉750g、馬鈴薯澱粉250g、かんすい3g、食塩5gにコラーゲンペプチド(分子量3000)4g及びアルギン酸3gを配合した麺塊を320mlの加水量で混捏し、製麺した後に、切刃:20角、麺厚:1.30mmで切り出し、連続的に0.5kg/cmで3分間蒸煮した後に、麺重130gに裁断した蒸し麺を乾燥用型枠に充填した。その後、温度100℃、風速4m/秒に調整した予備乾燥段階を4分間実施し、水分を25%に調整した後に、温度120℃、風速10m/秒に調整した乾燥機内で2分間乾燥させ、最終水分7%の即席中華袋麺を得た。
【0052】
[実施例6] 小麦粉800g、タピオカ澱粉200g、かんすい4g、食塩10gにコラーゲンペプチド(分子量3000)4g及びペクチン3gを配合した麺塊を340mlの加水量で混捏し、製麺した後に、切刃:20角、麺厚:1.20mmで切り出し、連続的に0.5kg/cmで3分間蒸煮した後に、麺重115gに裁断した蒸し麺を乾燥用型枠に充填した。その後、温度85℃の熱風で60分間乾燥させ、最終水分10%の熱湯注加タイプの即席中華麺を得た。
【0053】
ここで比較のために、本実施の形態の範囲外である比較例の幾つかを次に挙げる。
【0054】

【0060】
この表4の結果から、即席和風麺及び即席欧風麺においても、実施例において良好な効果が得られることが分かる。また、煮込みタイプの即席熱風乾燥麺においても、効果が得られることが分かる。更には、麺線を発泡させずに乾燥した即席熱風乾燥麺においても、麺線のみずみずしさが顕著に良くなり、かつ長期保存時の食感の安定性も良好となり、効果が期待できる。
【0061】
このように、コラーゲンペプチドがその保護コロイド性により、主原料である小麦粉中の澱粉及び添加した澱粉の疎水基に吸着し、更には低吸湿性増粘多糖類の保水性及び増粘性が、澱粉の抱えている水分の離水を防ぐことで、効果的に澱粉の老化を抑制し、食感の経時変化を抑制することができる。また、即席高温熱風乾燥麺においては、喫食事においてポーラスな構造の穴をコラーゲンペプチド及び低吸湿性増粘多糖類が速やかに熱水吸収し塞ぐことで即席高温熱風乾燥麺特有のスカスカとした軽い食感を脱することができ、「生麺のような粘弾性」を有しかつ「生麺のようなみずみずしい麺線」を合わせて実現することができる。
【0062】

以上説明したように本発明に係る即席熱風乾燥麺の製造方法によれば、乾燥麺であっても、食感の経時変化を抑制し、生麺のような粘弾性を有し、かつ生麺のようなみずみずしい食感を実現した麺を得ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing instant hot-air dried noodles containing a collagen peptide and a low-hygroscopic thickening polysaccharide with respect to flour.
[0002]
[Prior art]
Conventional methods for drying instant noodles include fried and non-fried noodles. As the non-frying drying method, generally, drying methods such as hot air drying, microwave drying, freeze drying, and cold drying are known. Raw materials are wheat flour and various starches.For Chinese noodles, use Kansai, and for Japanese-style noodles, use polymerized phosphate instead of Kansai, and add salt, powdered egg, thickening polysaccharides, fats and oils as necessary. , Lecithin and other ingredients are added, kneaded, and then made into noodles. After steaming, fried noodles and non-fried noodles (non-fried noodles) are obtained by a predetermined drying method.
[0003]
In addition, methods of eating these instant noodles are roughly classified into two types: stew-cooking in a pot and cooking by pouring in hot water. The type of stew cooking in a pot has a large amount of heat at the time of cooking, so that the boiling water quickly spreads to the inside of the noodle strings, and the starch particles can be sufficiently swollen, so that a relatively elastic texture can be realized. However, the type in which hot water of fried noodles and non-fried noodles are poured and cooked (hereinafter referred to as snack noodles) has a significantly smaller amount of heat at the time of cooking, so that it takes longer time for the hot water to reach the inside of the noodle strings. Since the starch particles inside the noodle strings cannot swell quickly, if the noodle strings are not flattened and processed thinly, they will have a hard texture.
[0004]
In recent years, consumers have become more and more oriented toward the real school. Instant noodles, especially non-fried and dried noodles, have `` viscoelasticity like raw noodles '' and `` like raw noodles '' It is desired to realize a “fresh texture”.
[0005]
In the low-temperature hot-air drying method, since the drying temperature is less than 100 ° C., the moisture of the noodle strings can be gradually dried, so that the structure of the noodles is dense without bubbles. As a result, a relatively elastic texture can be reproduced, but there is a disadvantage that the structure of the noodle strings is so dense that moisture does not easily penetrate into the noodle strings during eating.
[0006]
Therefore, conventionally, in the low-temperature hot-air drying method, a method of increasing the ratio of various types of starch to wheat flour has been adopted in order to enhance the resilience of the noodle strings. However, if the amount of added starch is excessively large, the resilience is improved and the texture becomes fresh, but the inherent sticky texture of wheat is weakened, the starch texture becomes strong, and `` like raw noodles ''"Viscoelasticity" is far from.
[0007]
The high-temperature hot-air drying method devised to eliminate the drawbacks of the low-temperature hot-air drying method has a drying temperature of 100 ° C. or more and a hot air speed of about 10 m / sec. Therefore, it is rapidly dehydrated and dried at a temperature higher than the boiling point of water. As a result, the appearance of the noodles becomes foamed by drying, the structure of the noodles becomes as porous as the fried noodles, and a noodle string having a volume similar to that of raw noodles can be obtained. However, because of its porous structure, the texture is unsatisfactory to eat and it is not possible to realize "viscoelasticity like raw noodles".
[0008]
Furthermore, the dried noodles made by the instant hot air drying method have a problem that the difference between the freshly prepared texture and the texture after a while, that is, the so-called time-dependent change is large, and especially hot water is poured. This change over time is remarkable in a snack noodle type cooked and cooked. Specifically, even when the texture of freshly formed food is fresh and excellent in viscoelasticity, as the days pass, the freshness of the noodle strings is lost, and the texture tends to be a texture without viscoelasticity Is strong.
[0009]
The cause of the above-mentioned temporal change in the texture may be considered to be aging of the starch in the wheat flour or the added starch, and that the moisture distribution in the noodle strings immediately after drying changes with time, that is, causes a moisture gradient.
[0010]
It has been found that the aging of starch can be delayed by its nature by giving sufficient moisture and gelatinizing. That is, before performing the pregelatinization treatment on the instant hot-air dried noodles, sufficient moisture is given to the noodle strings to sufficiently swell and disintegrate the starch, thereby preventing aging of the starch. However, in general, instant hot-air dried noodles are limited to a moisture content of about 40% with respect to the noodle strings due to productivity and economic efficiency.
[0011]
Here, in instant hot-air dried noodles, several methods have been disclosed as a method for imparting sufficient moisture to the noodle strings and gelatinizing them. Patent Literature 1 discloses a method in which a noodle string is subjected to treatment such as immersion in hot water at 60 ° C to 100 ° C, and the noodle string is steamed. According to this method, the noodle strings can be gelatinized and swelled more than the conventional method. However, when the inventor conducted an experiment, it was not possible to sufficiently suppress the temporal change of the texture.
[0012]
Patent Document 2 discloses a process in which noodle strings are boiled with a salt solution having a salt concentration of 20% (W / V) to a saturated concentration, and then the noodle strings are washed with cold water. Certainly, when treated with hot water rather than steaming, starch in the noodle strings can be given sufficient moisture and gelatinized, but the salty taste of the noodle strings becomes strong, further complicating the manufacturing process. Therefore, there is a problem of wastewater treatment and the like, and there is a problem in economy.

[Problems to be solved by the invention]
In instant hot-air dried noodles, especially in a high-temperature hot-air drying method, it is possible to suppress the temporal change of the texture, to have “viscoelasticity like raw noodles”, and to realize “fresh texture like raw noodles”. With the aim of finding a method for producing instant hot-air dried noodles that can be made, the present inventors have conducted intensive research, and while improving productivity and economic efficiency, to improve the aging of the texture, the starch has an excellent anti-aging effect. An experiment was conducted by adding a collagen peptide having a property of strong water retention to a noodle raw material.
[0015]
As a method for adding a collagen peptide to noodles, Patent Document 3 discloses a method for modifying a cereal food, which comprises adding a collagen peptide having a molecular weight of 1,000 to 10,000 to the cereal food. This indicates that the collagen peptide is kneaded, and the present inventors have conducted an experiment. As a result, even if a single collagen peptide was added, the change over time was not completely suppressed.
[0016]
[Patent Document 3]
JP-A-54-10619
An object of the present invention is to solve the above-mentioned problems, suppress the temporal change of the texture, have viscoelasticity like raw noodles, and realize a fresh texture like raw noodles. An object of the present invention is to provide a method for producing hot-air dried noodles.
[0018]
[Means for Solving the Problems]
In order to achieve the above object, a method for producing an instant hot-air dried noodle according to the present invention comprises the steps of: kneading a noodle raw material obtained by mixing a flour flour with a collagen peptide and a low-hygroscopic thickening polysaccharide; and water to form a noodle mass. The method is characterized by comprising one step, a second step of noodle-making the noodle mass, a third step of steaming the noodle strings, and a fourth step of drying the steamed noodle strings with hot air.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described in detail based on the illustrated embodiment.
In the present embodiment, as shown in FIG. 1, first, as a first step, a noodle raw material containing collagen peptide and a low-hygroscopic thickening polysaccharide and water are kneaded with flour to prepare a noodle mass. Next, the dough is made into noodles as a second step, the noodle strings are steamed as a third step, and the noodle strings are dried with hot air as a fourth step.
[0020]
The method for producing a collagen peptide used in the present embodiment is not particularly limited, but a collagen peptide is a protein obtained by hydrolyzing a protein called collagen obtained from animal bones, skins, and the like with an enzyme to reduce the molecular weight. Similarly, collagen produced from collagen is a protein that does not dissolve in cold water having a molecular weight of tens of thousands to 300,000 and has no gelling ability, whereas a collagen peptide has a molecular weight of several thousand to tens of thousands and has no gelling ability. It is a protein.
[0021]
Generally, gelatin is produced from collagen, and collagen peptide is produced from gelatin. For this reason, when producing gelatin from collagen, a raw material containing collagen is treated with an alkali or an acid. Therefore, two types of collagen peptides having different isoionic points are present. Those subjected to the alkali treatment have isoionic points of 6 to 9, and those subjected to the acid treatment have isoionic points of 4 to 5, but in the present embodiment, the isoionic points are not particularly limited.
[0022]
The collagen peptide used in the present embodiment preferably has a molecular weight of 1,000 to 5,000. Specifically, Nitta Gelatin Co., Ltd. SCP-3100 (molecular weight 3000), Nitta Gelatin Co., Ltd. SCP-5100 (molecular weight 5000), Nitta Gelatin Co., Ltd. LCP fine powder (molecular weight 2000), Miyagi Chemical Industry Co., Ltd. CPB- 5 (molecular weight 5000).
[0023]
If the molecular weight exceeds 5,000, the properties as a protein will appear strongly, and the texture will be unfavorable, and further, the animal odor peculiar to collagen will be worrisome. When the molecular weight is 1,000 or less, the properties as a collagen peptide are weakened and no effect can be obtained, and further, the properties of amino acids are strongly exhibited and the flavor is not excellent.
[0024]
The amount of the collagen peptide to be added is preferably 0.1 to 2%, preferably 0.2 to 1% based on the flour. If the amount of the collagen peptide is small, the effect cannot be obtained, and if it exceeds 2%, the noodle strings become sticky and the productivity is reduced, and the texture is not good.
[0025]
The low-hygroscopicity thickening polysaccharide in the present embodiment refers to a thickening polysaccharide having a low water-absorbing property in a substance itself in a state of low water content. The meaning of water absorption in a state of high water content, that is, water absorption in an aqueous solution or the like, is different. When a thickening polysaccharide having extremely high hygroscopicity is used, water contained in the starch is absorbed violently, so that aging of the starch is rather likely to occur, which causes a change with time.
[0026]
Specific examples of the low-hygroscopic thickening polysaccharide include pectin, alginic acid, tamarind seeds, tara gum, guar gum, carrageenan, pullulan, gum arabic, and particularly preferably pectin, alginic acid, tamarind seeds, tara gum, guar gum. is there. By using these low-hygroscopic thickening polysaccharides, it is possible to effectively prevent the separation of starch granules from water due to the water retention and thickening properties, which are general properties of thickening polysaccharides. Due to the synergistic effect with the peptide, the change over time in the texture can be suppressed.
[0027]
The amount of the low-hygroscopic thickening polysaccharide to be added depends on the type of the thickening polysaccharide, but is preferably 0.01 to 1%, preferably 0.05 to 0.5%, based on the flour. When the amount is too large, adverse effects such as too hard texture occur, and when the amount is small, the effect cannot be obtained.
[0028]
FIG. 2 shows the results of a hygroscopic test of the thickening polysaccharide to clarify the hygroscopicity of the thickening polysaccharide. In the test method, 10.00 g of each thickening polysaccharide sample is accurately weighed in a plastic petri dish of known weight. The sample was allowed to stand in an incubator (temperature: 35 ° C., humidity: 72%) (open), the weight was measured over time, and the absorption was determined by the following equation.
Moisture absorption (%) = (weight after standing-initial weight) / initial weight x 100
[0029]
FIG. 2 shows that there is a difference in hygroscopicity depending on the type of the thickening polysaccharide. Soy polysaccharides, xanthan gum, and the like have high water absorption because of their high hygroscopicity, but cannot suppress changes over time. It is also found that pectin, alginic acid, tamarind seed, cod gum, guar gum and the like have relatively low hygroscopicity. By using such a low-hygroscopic thickening polysaccharide in combination with a collagen peptide, it is possible to prevent starch from syneresis and aging, and to suppress a temporal change in texture.
[0030]
In addition, in order to clarify the synergistic effect of the collagen peptide and the low-hygroscopic thickening polysaccharide, a long-term storage test was performed on instant hot-air dried noodles using and not using a collagen peptide (molecular weight 3000) and pectin, respectively. . The test method was performed based on Example 1 described later. Table 1 shows the evaluation of the texture.
[0031]
Figure 2004344081
[0032]
From the results in Table 1, it is not possible to suppress the change over time of the texture by adding the collagen peptide or pectin which is a low-hygroscopic thickening polysaccharide alone, and the viscoelasticity and freshness of the obtained noodle strings are inferior. You can see that. That is, by adding the collagen peptide and pectin which is a low-hygroscopic thickening polysaccharide in combination, it is possible to suppress the temporal change of the texture and to obtain instant hot-air dried noodles excellent in the texture.
[0033]
The instant hot-air dried noodles in the present embodiment are not particularly limited in the type and product form, and are, for example, stewed types such as Chinese noodles, udon, and buckwheat, and types in which hot water is poured and cooked. Improving the suitability for production and improving the texture of instant noodles of hot hot air dried noodles, which are types of pouring and cooking.
[0034]
The instant hot-air dried noodles to which the present embodiment is applied are prepared by mixing collagen peptide having a molecular weight of 1,000 to 5,000 and low-humidity thickening polysaccharide with wheat flour as a main raw material, The raw materials are added, kneaded, and after the composite noodles are made, the noodle strings are cut out with a cutting blade to obtain raw noodle strings, which are continuously steamed and then formed and filled into a drying basket one by one. Thereafter, if necessary, a flavoring liquid, an emulsifier, an oil or fat, a soothing agent such as soybean polysaccharide, or the like is adhered to the surface of the noodle strings, and subjected to a hot-air drying treatment to obtain a desired noodle string.
[0035]
In addition, the kneading method in the first step at this time may be carried out under a normal pressure or a reduced pressure by a conventionally known device, and in the latter case, a vacuum mixer or the like can be used. By using a vacuum mixer, gluten can be efficiently produced at the time of kneading, so that the effect of “viscoelasticity like raw noodles” is promoted. In the hot air drying step of the fourth step, the noodle strings may be passed through a dryer adjusted to a temperature of 80 to 160 ° C. for 10 to 80 minutes and dried so that the water content of the noodle strings becomes about 10%.
[0036]
Here, a method for producing an instant high-temperature hot-air dried noodle in which the present embodiment particularly exerts its effect will be described, but the effect is not necessarily limited based on the drying method. Immediate high-temperature hot-air dried noodles usually have two steps: preliminary drying for adjusting the water content of the noodle strings to 15 to 25%, and main drying for foaming and drying the pre-dried noodle strings in order to prevent sudden noodle foaming. Can be broadly divided.
[0037]
In the predrying step, the noodle strings are heated to a temperature of 80 to 115 ° C. (preferably 95 to 105 ° C.) and heated at a wind speed of 1 to 10 m / sec (preferably 3 to 5 m / sec) to reduce the water content of the noodle mass to 15 to 10 m / sec. By adjusting the concentration to 25%, the main portion of the noodle strings can be quickly and efficiently dried at the time of main drying with high-temperature high-speed hot air, and rapid foaming can be prevented.
[0038]
If the water content of the noodle mass is 25% or more, rapid foaming of the noodle strings cannot be prevented at the time of final drying, and uniform foaming cannot be performed. Wake up. In addition, when the water content is 15% or less, foaming of the noodle strings hardly occurs in the main drying. If the temperature is lower than 80 ° C., the drying efficiency is poor, and the drying time becomes longer. If the temperature is higher than 115 ° C., the drying becomes difficult, and the foaming of the noodle strings starts. Can not. Further, if the wind speed is 1 m / sec or less, the inside of the noodle mass cannot be ventilated, causing unevenness in preliminary drying. If the wind speed is 10 m / sec or more, the noodle mass is pressed against the upper or lower part of the mold, and as a result, The lumps do not become coarse and uniform preliminary drying cannot be performed, resulting in uneven drying, and the loosening of the noodle strings during eating becomes worse.
[0039]
In the main drying step, the noodle strings are dried by hot air adjusted to a temperature of 110 to 145 ° C (preferably 115 to 135 ° C) and a wind speed of 5 to 25 m / sec (preferably 8 to 20 m / sec). The required time is 2 to 4 minutes, and the noodle strings are foam-dried while keeping the moisture in the noodles at 7 to 14%.
[0040]
This main drying step is a step of evaporating the moisture in the noodles at a stretch by high-temperature, high-speed hot air, and the foaming state of the noodles is formed by the rapid evaporation. Here, when the temperature is 110 ° C. or lower, foaming does not occur, and when the temperature is 145 ° C. or higher, the noodle strings are partially scorched and the commercial value is impaired. Further, when the wind speed is 5 m / sec or less, the drying efficiency is poor, and when the wind speed is 25 m / sec or more, unnecessary energy is industrially applied.
[0041]
Next, the effects of the present embodiment will be specifically described with reference to examples.
[0042]
[Example 1] For noodles produced by adding a collagen peptide, a comparative test was carried out using several collagen peptides as follows in order to show the effect due to the difference in molecular weight.
[0043]
800 g of wheat flour, 200 g of tapioca starch, 3 g of watermelon, 10 g of salt, 10 g of collagen peptide or water-soluble gelatin or gelatin having the molecular weights shown in Table 2 were kneaded with noodle mass prepared by mixing 5 g and 3 g of pectin with 320 ml of water. After the cutting, the slices were cut out at a cutting edge of 18 rounds and a noodle thickness of 1.20 mm, steamed continuously at 0.5 kg / cm 2 for 3 minutes, and then steamed noodles cut into a noodle weight of 115 g were filled in a drying mold. . Thereafter, a preliminary drying step of adjusting the temperature to 100 ° C. and the wind speed of 4 m / sec was performed for 3 minutes, and after adjusting the water content to 24%, drying was performed for 2 minutes in a dryer adjusted to the temperature of 120 ° C. and the wind speed of 10 m / sec. Then, instant Chinese noodles of a hot water pouring type having a final moisture of 8% were obtained. The texture evaluation is shown in the following Table 2 by comparing the taste and texture according to the molecular weight of the collagen peptide.
[0044]
Figure 2004344081
[0045]
From the results in Table 2, it can be seen that when the molecular weight of the collagen peptide exceeds 5000, the taste and texture are not excellent. That is, when a collagen peptide having a molecular weight of 1,000 to 5,000 is used, good instant hot-air dried noodles can be produced.
[0046]

After noodles, cut out with a cutting blade: 18 rounds, noodle thickness: 1.00 mm, steamed continuously at 0.5 kg / cm 2 for 3 minutes, and then filled into a drying mold with steamed noodles cut into 115 g of noodle weight. did. Thereafter, a preliminary drying step of adjusting the temperature to 100 ° C. and the wind speed of 4 m / sec was performed for 4 minutes, and after adjusting the water content to 24%, drying was performed for 2 minutes by a dryer adjusted to the temperature of 120 ° C. and the wind speed of 10 m / sec. Instant European-style noodles of boiling water pouring type with a final moisture of 8% were obtained.
[0051]
[Example 5] A noodle mass obtained by mixing 750 g of wheat flour, 250 g of potato starch, 3 g of brassicae, 5 g of salt, 4 g of collagen peptide (molecular weight 3,000) and 3 g of alginic acid with 320 ml of water and kneading the noodles, and then cutting the noodle: Twenty squares, noodle thickness: cut out at 1.30 mm, steamed continuously at 0.5 kg / cm 2 for 3 minutes, and then steamed noodles cut into a noodle weight of 130 g were filled in a drying mold. Thereafter, a preliminary drying step of adjusting the temperature to 100 ° C. and the wind speed of 4 m / sec was performed for 4 minutes, and after adjusting the water content to 25%, the film was dried for 2 minutes in a dryer adjusted to the temperature of 120 ° C. and the wind speed of 10 m / sec. An instant Chinese bag noodle having a final moisture of 7% was obtained.
[0052]
[Example 6] A noodle mass obtained by mixing 800 g of wheat flour, 200 g of tapioca starch, 4 g of brine, 4 g of collagen peptide (molecular weight 3,000) and 3 g of pectin in 10 g of salt and kneading with 340 ml of water, and after making noodles, cutting edge: Twenty squares, noodle thickness: cut out at 1.20 mm, steamed continuously at 0.5 kg / cm 2 for 3 minutes, and steamed noodle cut into 115 g of noodle weight was filled in a drying mold. Thereafter, the resultant was dried with hot air at a temperature of 85 ° C. for 60 minutes to obtain a hot water pouring type instant Chinese noodle having a final moisture of 10%.
[0053]
Here, for comparison, some comparative examples that are outside the scope of the present embodiment will be described below.
[0054]
[Comparative Example 1] 4 g of collagen peptide (molecular weight 3000) and 1.5 g of enzymatically decomposed guar gum, which are the components of Example 3, were not used, and the other conditions were the same as in Example 3.
[0055]
Comparative Example 2 4 g of collagen peptide (molecular weight: 2,000) and 3 g of tamarind seed gum, which are the components of Example 4, were not used, and the other conditions were the same as in Example 4.
[0056]
[Comparative Example 3] 4 g of collagen peptide (molecular weight: 3000) and 3 g of alginic acid, which are the components of Example 5, were not used, and the other conditions were the same as in Example 4.
[0057]
Comparative Example 4 4 g of collagen peptide (molecular weight 3000) and 3 g of pectin, which are the components of Example 6, were not used, and the other conditions were the same as in Example 4.
[0058]
The evaluations of Examples 3, 4, 5, 6 and Comparative Examples 1, 2, 3, and 4 are shown in Table 4 below. However, in Table 4, the examples are actually examples, and the ratios are comparative examples.
[0059]
Figure 2004344081
[0060]
From the results in Table 4, it can be seen that good effects can be obtained in the examples also for instant Japanese-style noodles and instant European-style noodles. Further, it can be seen that the effect can be obtained also in the instant hot air dried noodles of the stewed type. Furthermore, even in the instant hot-air dried noodles dried without foaming the noodle strings, the freshness of the noodle strings is remarkably improved, and the stability of the texture during long-term storage is improved, and the effect can be expected.
[0061]
As described above, the collagen peptide is adsorbed on the starch in the wheat flour, which is the main raw material, and the hydrophobic group of the added starch due to its protective colloid property, and further, the water retention and thickening of the low-hygroscopic thickening polysaccharide are increased by the starch. By preventing the separation of water contained in the starch, the aging of the starch can be effectively suppressed, and the change over time in the texture can be suppressed. In addition, in the instant hot hot air dried noodles, the pores of the porous structure in the meal are quickly absorbed by the collagen peptide and the low-hygroscopic thickening polysaccharide in hot water and closed, so that the instant hot hot air dried noodles have a light and crisp characteristic. The texture can be removed, and it can be realized in combination with "fresh noodle strings like raw noodles" having "viscoelasticity like raw noodles".
[0062]
【The invention's effect】
As described above, according to the method for producing instant hot-air dried noodles according to the present invention, even if the noodles are dried, the change in texture over time is suppressed, the viscoelasticity is similar to that of raw noodles, and raw noodles It is possible to obtain noodles having a fresh texture as described above.
