Description

本発明は、半生麺類の製造方法に関する。   The present invention relates to a method for producing semi-raw noodles.

従来、半生麺は、一般的に、生麺を冷風乾燥や温風乾燥により、あるいはまた生麺を乾燥した後加湿して水分調整することにより、製造されていた。しかしながら、斯かる従来の方法により得られた半生麺は、保存性に問題があると共にそもそも乾燥処理に長時間を要すると云う問題があった。   Conventionally, semi-raw noodles are generally produced by drying raw noodles by cold air drying or hot air drying, or by drying the raw noodles and then humidifying them to adjust the water content. However, the semi-raw noodles obtained by such a conventional method have a problem of storage stability and a long time for drying.

そこで、当該乾燥時間の短縮を目的として過熱蒸気を用いて生麺を乾燥、殺菌して半生麺とする半生麺類の製造方法も提案されている(例えば、特許文献1参照)。
しかしながら、この方法によれば、乾燥時間は短縮されるものの、麺の保存性については何ら改善されず、未だ満足のいく半生麺が得られなかったのが実状であった。
In view of this, a method for producing semi-raw noodles is proposed in which raw noodles are dried and sterilized using superheated steam to make the semi-noodles for the purpose of shortening the drying time (see, for example, Patent Document 1).
However, according to this method, although the drying time was shortened, the storage stability of the noodles was not improved at all, and a satisfactory semi-raw noodle was still not obtained.

特開2002−335895号公報JP 2002-335895 A

本発明は、上記の如き従来の問題と実状に鑑みてなされたものであり、従来の半生麺に比し、保存性に優れた半生麺類を提供することを課題とするものである。   This invention is made | formed in view of the above conventional problems and actual condition, and it makes it a subject to provide the semi-noodles excellent in preservability compared with the conventional semi-noodles.

本発明者は、上記課題を解決すべく鋭意研究を重ねた結果、生地原料に食塩と水を添加して麺生地を作製した後、麺線を形成し、次いで得られた麺線に飽和水蒸気を接触させた後、麺の水分含量が20〜25%になるように乾燥すれば、保存性が向上し、しかも喫食時の食感も良好な半生麺類が得られることを見出し、本発明を完成した。   As a result of intensive research to solve the above problems, the present inventor made noodle dough by adding salt and water to the dough raw material, and then formed noodle strings, and then the obtained noodle strings were saturated with water vapor. After the contact, the noodles are dried so that the moisture content is 20 to 25%, and it is found that semi-noodles with improved shelf life and good texture during eating can be obtained. completed.

すなわち、本発明は、生地原料に食塩と水を加えて麺生地を作製した後、麺線を形成し、次いで得られた麺線に飽和蒸気を接触させた後、麺の水分含量が20〜25%になるように乾燥することを特徴とする半生麺類の製造方法により、上記課題を解決したものである。   That is, in the present invention, a noodle dough is formed by adding salt and water to a dough raw material, and then a noodle string is formed. The above-mentioned problem is solved by a method for producing semi-noodles characterized by drying to 25%.

本発明の製造方法によれば、従来の半生麺に比し、保存性に優れた半生麺類が得られ、しかも従来の半生麺の喫食時の食感に勝るとも劣らない優れた食感の半生麺類を得ることができる。   According to the production method of the present invention, it is possible to obtain semi-raw noodles having excellent storage stability compared to conventional semi-raw noodles, and also to have an excellent texture that is not inferior to the texture at the time of eating of conventional semi-noodles. Noodles can be obtained.

本発明は、まず、生地原料に食塩と水を加えて麺生地を作製する。   In the present invention, first, salt and water are added to a dough raw material to prepare a noodle dough.

生地原料としては、主成分としての穀粉が挙げられるが、穀粉の種類は特に限定されず、例えば、強力粉、準強力粉、中力粉、薄力粉、デュラム小麦粉;蕎麦粉;米粉等が挙げられる。麺の種類に応じて、これら小麦粉は、単独で又は2種以上組み合わせて使用することができる。例えば、パスタ類にはデュラム小麦、中華麺には準強力粉、うどん、そうめんには中力粉等を主として用いることができる。   Examples of the dough material include flour as a main component, but the type of flour is not particularly limited, and examples thereof include strong flour, semi-strong flour, medium flour, thin flour, durum wheat flour, oat flour, rice flour and the like. Depending on the type of noodle, these flours can be used alone or in combination of two or more. For example, durum wheat can be used for pasta, quasi-strong flour for Chinese noodles, udon, somen for medium noodles.

生地原料には、上記穀粉の他、任意成分として、炭酸ナトリウム、炭酸カリウム、乳酸カルシウム、ポリリン酸カリウム、カンスイ;大豆油、菜種油、バター、マーガリン等の動植物性油脂;グリセリン脂肪酸エステル等の乳化剤;トウモロコシ澱粉、タピオカ澱粉等の生澱粉類やそれらのリン酸架橋等した化工澱粉;食物繊維;卵白等の卵製品;脱脂粉乳やその他の乳製品;小麦粉グルテン等の蛋白強化剤;グアガム、キサンタンガム、カラギーナン等の増粘剤;ショ糖等の糖質;クエン酸、酢酸等の酸味料;ビタミン、ミネラル、アミノ酸等の栄養強化剤;保存剤;酵素剤;pH調整剤;酵母エキス等を用いることができる。これら任意成分は、単独で又は2種以上組み合わせて使用することができる。   In addition to the above flour, the dough raw materials include sodium carbonate, potassium carbonate, calcium lactate, potassium polyphosphate, kansui; animal and vegetable oils such as soybean oil, rapeseed oil, butter, margarine; Raw starches such as corn starch and tapioca starch, and modified starches such as those phosphoric acid cross-linked; dietary fiber; egg products such as egg white; skim milk powder and other dairy products; protein fortifiers such as wheat flour gluten; Thickeners such as carrageenan; sugars such as sucrose; acidulants such as citric acid and acetic acid; nutrient enhancers such as vitamins, minerals and amino acids; preservatives; enzyme agents; pH adjusters; Can do. These optional components can be used alone or in combination of two or more.

上記生地原料に添加される食塩の量は、通常添加される量より多量とするのが好ましい。通常食塩は、生地原料100質量部に対して、パスタ類(スパゲッティ、マカロニ等)の場合、0〜1質量部;うどん(ひやむぎ、そうめん)の場合、4〜5質量部;日本蕎麦の場合、0〜2質量部;中華麺の場合、0〜2質量部を添加するが、斯様な食塩の添加量では、十分な微生物の増殖抑制が得られにくい。
そのため、通常添加される食塩の量に、更に生地原料100質量部に対して、2〜11質量部、好ましくは2〜8質量部、より好ましくは3〜7質量部を追加するのが、有利である。追加する食塩の量が2質量部未満では、微生物の増殖を十分に抑えにくく、他方で8質量部を超えると喫食時の麺の塩味が強くなり易い。
また、上記生地原料に添加する食塩は、生地原料にそのまま添加してもよいが、食塩水として添加するのが、麺生地中の食塩濃度のばらつきを抑える点で、好ましい。
The amount of salt added to the dough raw material is preferably larger than the amount usually added. Usually, salt is 0 to 1 part by weight for pasta (spaghetti, macaroni, etc.), 4 to 5 parts by weight for udon (hiyamamugi, somen) for 100 parts by weight of dough raw material; 0-2 parts by mass; In the case of Chinese noodles, 0-2 parts by mass are added. However, with such an amount of sodium chloride, it is difficult to sufficiently suppress the growth of microorganisms.
Therefore, it is advantageous to add 2 to 11 parts by mass, preferably 2 to 8 parts by mass, more preferably 3 to 7 parts by mass, with respect to 100 parts by mass of the dough raw material, in addition to the amount of salt that is usually added. It is. If the amount of salt to be added is less than 2 parts by mass, it is difficult to sufficiently suppress the growth of microorganisms. On the other hand, if it exceeds 8 parts by mass, the salty taste of noodles during eating tends to be strong.
The salt added to the dough raw material may be added to the dough raw material as it is, but it is preferable to add it as a saline solution in terms of suppressing variations in salt concentration in the noodle dough.

麺生地の作製方法は特に限定されないが、例えば生地原料と添加された食塩(水)に適宜水を添加しながらミキシングによって麺生地を作製する方法等が挙げられる。ミキシングによって麺生地を作製する場合、3〜30分間、特に脱気しながら10〜20分間のミキシングを行うのが、喫食時に良好な食感の麺が得られる点で、好ましい。   The method for preparing the noodle dough is not particularly limited, and examples thereof include a method for preparing the noodle dough by mixing while appropriately adding water to the dough raw material and added salt (water). When producing noodle dough by mixing, it is preferable that mixing is performed for 3 to 30 minutes, particularly 10 to 20 minutes while deaeration, in order to obtain noodles having a good texture during eating.

次いで、本発明は、作製された麺生地から麺線を形成する。作製された麺線の水分含量は、通常の生麺の水分含量であればよく、具体的には26〜35質量%程度である。
麺線形成法としては特に限定されないが、例えば、上記麺生地をロール圧延機や減圧押出し機等にて麺帯を形成した後、得られた麺帯を切刃を用いて切り出すことによって麺線を形成する方法、あるいは押出し機にて押出しすることによって麺線を形成する方法等が挙げられる。
因みに、上記減圧押出し機による麺帯の形成は、真空度の高い減圧下、具体的には−0.06MPa(ゲージ圧)以下で行なうのが、弾性力に富む麺類が得られる点から好ましい。
Next, the present invention forms a noodle string from the produced noodle dough. The water content of the produced noodle strings may be the water content of ordinary raw noodles, specifically about 26 to 35% by mass.
The noodle strings forming method is not particularly limited. For example, the noodle strings are formed by forming the noodle strips with a roll mill or a vacuum extruder, and then cutting the obtained noodle strips with a cutting blade. And a method of forming noodle strings by extruding with an extruder.
Incidentally, the formation of the noodle band by the reduced pressure extruder is preferably carried out under reduced pressure with a high degree of vacuum, specifically, −0.06 MPa (gauge pressure) or less from the viewpoint of obtaining noodles rich in elasticity.

更に、本発明は、上記作製された麺線に飽和水蒸気を接触させる。これによって、微生物の増殖を十分に抑えることができるので半生麺類の保存性が向上し、しかも喫食時の麺の食感が良好となるのに対し、麺線に飽和水蒸気を接触させない場合には、微生物の増殖を十分に抑えることができず、本発明の課題を解決し得ない。
このとき、飽和水蒸気の温度は、85〜110℃、好ましくは90〜105℃、特に好ましくは93〜103℃とし、その時の接触時間を1〜80分間、好ましくは3〜60分間、より好ましくは3〜40分間、更に好ましくは10〜40分間、より更に好ましくは10〜30分間、特に好ましくは10〜20分間とするのが、有利である。
具体的には、飽和水蒸気を接触させる処理時間は上記範囲において各種麺類に応じて調整するのが好ましく、例えば、パスタ類(スパゲッティ、マカロニ等)の場合、3〜65分間、特に10〜30分間とするのが、好ましい。また、うどんの場合、10〜80分間、特に10〜45分間とするのが好ましい。ひやむぎの場合、5〜50分間、特に10〜35分間とするのが好ましい。そうめんの場合、5〜40分間、特に10〜30分間とするのが好ましい。中華麺の場合、5〜60分間、特に10〜40分間とするのが好ましい。日本蕎麦の場合、5〜60分間、特に10〜40分間とするのが好ましい。
飽和水蒸気を接触させる際には、麺線を130〜155gの小分けにするのが、麺線全体に水蒸気が満遍なく接触し易くなるので半生麺類の保存性を向上せしめる上で、好ましい。
Furthermore, in the present invention, saturated steam is brought into contact with the noodle strings produced as described above. As a result, the growth of microorganisms can be sufficiently suppressed, so that the preservation of semi-noodles is improved, and the texture of the noodles during eating is good, whereas when the saturated steam is not in contact with the noodle strings The growth of microorganisms cannot be sufficiently suppressed, and the problems of the present invention cannot be solved.
At this time, the temperature of the saturated water vapor is 85 to 110 ° C., preferably 90 to 105 ° C., particularly preferably 93 to 103 ° C., and the contact time at that time is 1 to 80 minutes, preferably 3 to 60 minutes, more preferably It is advantageous that the time is 3 to 40 minutes, more preferably 10 to 40 minutes, even more preferably 10 to 30 minutes, and particularly preferably 10 to 20 minutes.
Specifically, the treatment time for contacting with saturated water vapor is preferably adjusted in accordance with various noodles in the above range. For example, in the case of pasta (spaghetti, macaroni, etc.), it is 3 to 65 minutes, particularly 10 to 30 minutes. Is preferable. In the case of udon, it is preferably 10 to 80 minutes, particularly 10 to 45 minutes. In the case of hiyamemugi, it is preferably 5 to 50 minutes, particularly 10 to 35 minutes. In the case of somen, it is preferably 5 to 40 minutes, particularly 10 to 30 minutes. In the case of Chinese noodles, it is preferably 5 to 60 minutes, particularly 10 to 40 minutes. In the case of Japanese soba, it is preferably 5-60 minutes, particularly 10-40 minutes.
When the saturated steam is brought into contact, it is preferable to divide the noodle strings into 130 to 155 g in order to improve the preservability of the semi-noodles because the steam easily contacts the entire noodle strings evenly.

尚、飽和水蒸気を接触させるときの圧力は、実質的に常圧(約1気圧)であればよく、具体的には0.95〜1.05気圧の範囲内とするのが好ましい。   In addition, the pressure at the time of making saturated water vapor contact should just be a substantially normal pressure (about 1 atmosphere), and it is preferable to specifically set it in the range of 0.95-1.05 atmosphere.

また、麺線に飽和水蒸気を接触させる手段としては、例えば、飽和水蒸気の雰囲気下に麺線を置く方法;飽和水蒸気を麺線に直接噴霧する方法等が挙げられる。   Examples of means for bringing saturated steam into contact with the noodle strings include a method of placing the noodle strings in an atmosphere of saturated steam; a method of spraying saturated steam directly onto the noodle strings.

更に、本発明は、飽和水蒸気に接触させた麺線を、麺線の水分含量が20〜25%、特に好ましくは23〜25%になるように乾燥する。麺線の水分含量が25%超では微生物の増殖を十分に抑えることができないので本発明の課題を解決し得ず、他方麺線の水分含量が20%未満の場合には、喫食時の麺の食感(特に麺のコシの強さ及び滑らかさ)が非常に悪い。これに対し、麺線の水分含量が20〜25%の範囲内であれば、半生麺類の保存性を向上せしめ、しかも喫食時の麺のコシ及び滑らかさも良好となる。
乾燥方法としては、特に限定されないが、例えば冷風乾燥、熱風乾燥、過熱蒸気、マイクロウェーブ等が挙げられる。このうち、熱風乾燥及び過熱蒸気乾燥が、半生麺類の乾燥むらを防止できる点で、好ましい。
ここに、乾燥温度は、特に限定されないが、4〜190℃、特に50〜190℃とするのが好ましく、また乾燥時間は1〜120分間、特に1〜60分間とするのが好ましい。
例えば、熱風乾燥の場合、乾燥温度は、50〜100℃、特に60〜100℃とするのが、喫食時に良好な食感の麺が得られる点で、好ましい。また、送風される気体の流速は、0.1〜2.5m/秒、特に0.3〜1.5m/秒とするのが好ましく、この気体としては、空気、窒素ガス、炭酸ガス等が挙げられるが、空気が低コストであるので望ましい。このときの処理時間は、5〜60分間、好ましくは10〜60分間、より好ましくは10〜30分間とするのが、有利である。
また、過熱蒸気の場合、蒸気温度は、110〜190℃、特に115〜140℃とし、その時の処理時間は、1〜30分間、特に3〜20分間とするのが、喫食時に良好な食感の麺が得られる点で、好ましい。
Furthermore, in the present invention, the noodle strings brought into contact with saturated water vapor are dried so that the moisture content of the noodle strings is 20 to 25%, particularly preferably 23 to 25%. If the moisture content of the noodle strings exceeds 25%, the growth of microorganisms cannot be sufficiently suppressed, so the problem of the present invention cannot be solved. On the other hand, if the moisture content of the noodle strings is less than 20%, the noodles at the time of eating The texture (especially the strength and smoothness of the noodles) is very bad. On the other hand, if the moisture content of the noodle strings is in the range of 20 to 25%, the preservability of the semi-noodles is improved, and the stiffness and smoothness of the noodles during eating are also good.
Although it does not specifically limit as a drying method, For example, cold air drying, hot air drying, superheated steam, a microwave etc. are mentioned. Of these, hot air drying and superheated steam drying are preferable in that uneven drying of semi-raw noodles can be prevented.
Although a drying temperature is not specifically limited here, It is preferable to set it as 4-190 degreeC, especially 50-190 degreeC, and it is preferable that drying time shall be 1 to 120 minutes, especially 1 to 60 minutes.
For example, in the case of hot air drying, it is preferable that the drying temperature is 50 to 100 ° C., particularly 60 to 100 ° C., because noodles having a good texture during eating can be obtained. The flow rate of the blown gas is preferably 0.1 to 2.5 m / sec, particularly 0.3 to 1.5 m / sec. Examples of the gas include air, nitrogen gas, carbon dioxide gas, and the like. Although desirable, air is desirable because of its low cost. The treatment time at this time is advantageously 5 to 60 minutes, preferably 10 to 60 minutes, more preferably 10 to 30 minutes.
In the case of superheated steam, the steam temperature is 110 to 190 ° C., particularly 115 to 140 ° C., and the treatment time is 1 to 30 minutes, particularly 3 to 20 minutes. It is preferable in that noodles can be obtained.

以上の手順により、作製された半生麺類は、従来の半生麺に比し、優れた保存性を保持する。しかも、これを電子レンジ、茹で、蒸し等によって加熱して喫食した場合には、良好な食感、特にコシや滑らかさの良好な麺が得られる。また、当該半生麺類は、加熱調理時のほぐれ性にも優れている。
半生麺類の種類としては、特に限定されず、例えば、パスタ類(スパゲッティ、マカロニ等)、うどん、ひやむぎ、そうめん、平めん、日本蕎麦、中華麺、ビーフン等が挙げられるが、食感が良好で保存性もよい点からパスタ類が好ましく、このパスタ類のなかでも特にスパゲッティが好ましい。
According to the above procedure, the prepared semi-noodles retain superior storage stability compared to conventional semi-noodles. In addition, when this is heated and eaten with a microwave oven, boiled, steamed, etc., noodles with good texture, particularly firmness and smoothness can be obtained. Moreover, the said semi-raw noodles are excellent also in the looseness property at the time of cooking.
The kind of semi-noodles is not particularly limited, and examples include pasta (spaghetti, macaroni, etc.), udon, hiyagigi, somen, flat noodles, Japanese soba noodles, Chinese noodles, rice noodles, etc. Pasta is preferable from the viewpoint of good preservability, and spaghetti is particularly preferable among these pasta.

得られた半生麺類を、保存性向上及び食感の保持の点から、無菌下で包装容器に充填することが好ましい。
包装容器の形状としては、袋状、カップ状、トレー状等が挙げられ、これらを適宜組み合わせて用いてもよいし、適宜押し蓋、かぶせ蓋、ピラード蓋等を用いてもよいが、生麺類の長期の保存性を維持するため密閉性の高いものが好ましい。
また、包装容器の素材としては、通常食品の包装容器に用いられる素材であればよく、例えば、ポリエチレンテレフタレート、結晶化ポリエチレンテレフタレート、ポリプロピレン、ポリエチレン、ポリスチレン、アルミニウム等及びこれらの複合材料が挙げられる。これらの素材のうち、耐熱性や耐電子レンジ性の点から、ポリプロピレンが好ましい。
The obtained semi-raw noodles are preferably filled into a packaging container under aseptic conditions from the viewpoint of improving the storage stability and maintaining the texture.
Examples of the shape of the packaging container include a bag shape, a cup shape, a tray shape, and the like. These may be used in appropriate combinations, or may be appropriately used as a push lid, a cover lid, a pillar lid, etc. In order to maintain long-term storage, a highly airtight material is preferable.
Moreover, the material of the packaging container may be any material that is normally used for food packaging containers. Examples thereof include polyethylene terephthalate, crystallized polyethylene terephthalate, polypropylene, polyethylene, polystyrene, aluminum, and composite materials thereof. Among these materials, polypropylene is preferable from the viewpoint of heat resistance and microwave resistance.
