The roasted wheat flour is obtained by drying wheat flour to have a moisture content of less than 5 mass%, and roasting the obtained wheat flour at a product temperature of 100 to 140°C for 10 to 90 minutes.

Description

本発明は、焙焼小麦粉およびその製造方法に関し、詳しくは、含有澱粉が実質的にα化されておらず、特定のグルテン・バイタリティーおよび白度を有し、風味および食感が向上した食品を得ることができる焙焼小麦粉、ならびにその製造方法に関する。   The present invention relates to roasted wheat flour and a method for producing the same, and more specifically, a food product in which the contained starch is not substantially pregelatinized, has specific gluten vitality and whiteness, and has improved flavor and texture. The present invention relates to a roasted flour that can be obtained, and a method for producing the same.

従来より、小麦粉を用いた食品の風味、食感、色などを改良するために、小麦粉を焙焼処理することが行なわれている。例えば、特許文献1には、水分含量を5%以上に保持しながら90〜110℃で小麦粉を焙焼処理する方法が記載されている。特許文献2には、110〜160℃で50〜150分間小麦粉を焙焼処理する方法が記載されている。特許文献1及び2に記載の方法においては、原料小麦粉として、水分含量が十数%の通常の小麦粉がそのまま用いられており、また、特許文献1には、水分含量が5%未満になると小麦粉の蛋白変性が不十分になることが記載されている。特許文献1及び2に記載の方法により得られた焙焼小麦粉では、風味、食感、色などの改良効果がある程度認められるものの、さらなる向上が求められている。   Conventionally, flour is roasted to improve the flavor, texture, color, and the like of foods using the flour. For example, Patent Document 1 describes a method of roasting wheat flour at 90 to 110 ° C. while keeping the water content at 5% or more. Patent Document 2 describes a method of roasting wheat flour at 110 to 160 ° C. for 50 to 150 minutes. In the methods described in Patent Documents 1 and 2, ordinary flour having a water content of more than 10% is used as it is as the raw material flour. In Patent Document 1, when the water content is less than 5%, the flour is used. It is described that the protein denaturation is insufficient. Although the roasted wheat flour obtained by the methods described in Patent Documents 1 and 2 has some improvement effects such as flavor, texture and color, further improvement is required.

また、小麦粉を揚げ物用のバッター液又は打ち粉に用いる場合には、風味および食感に加えて、衣と揚げ物種との結着性も良好であることが求められる。特許文献1に記載の方法により得られた焙焼小麦粉では、結着性は弱く、特許文献2に記載の方法により得られた焙焼小麦粉では、結着性を向上させることができるものの、この方法により結着性向上効果を得るには高い焙焼温度と長い焙焼時間を要し、それに伴ってコゲ臭が生じるという問題がある。   Moreover, when using wheat flour for the batter liquid or the flour for fried foods, in addition to the flavor and texture, it is required that the binding property between the clothes and the fried food type is also good. In the roasted wheat flour obtained by the method described in Patent Document 1, the binding property is weak. In the roasted wheat flour obtained by the method described in Patent Document 2, the binding property can be improved. In order to obtain the effect of improving the binding property by the method, there is a problem that a high roasting temperature and a long roasting time are required, and a burnt odor is generated accordingly.

従って、本発明の目的は、風味、食感などが一層向上した食品を得ることができる焙焼小麦粉、特に揚げ物用小麦粉として、衣の風味および食感を向上させ、さらに衣と揚げ物種との結着性も向上させることができる焙焼小麦粉、およびその製造方法を提供することにある。   Therefore, the object of the present invention is to improve the flavor and texture of clothing as a roasted flour, particularly flour for fried food, which can obtain a food with further improved flavor, texture, etc. An object of the present invention is to provide a roasted wheat flour capable of improving binding properties and a method for producing the same.

本発明者らは、焙焼小麦粉を用いた揚げ物について特に検討した結果、その風味および食感、さらに結着性を向上させるには、焙焼前の小麦粉の水分の調整が重要であり、とりわけ結着性に対してその影響が大きいことを知見した。さらなる検討の結果、本発明者らは、水分調整をした後に、特定のグルテン・バイタリティーおよび白度となるように焙焼して得られた焙焼小麦粉が、上記目的を達成し得ることを知見した。   As a result of particularly examining fried foods using roasted flour, the inventors of the present invention are important to adjust the moisture content of the flour before roasting in order to improve the flavor and texture, and the binding properties. It was found that the effect on the binding property was great. As a result of further studies, the present inventors have found that roasted flour obtained by roasting to a specific gluten vitality and whiteness after adjusting the water content can achieve the above object. I found out.

本発明は、上記知見に基づきなされたもので、含有澱粉が実質的にα化されておらず、グルテン・バイタリティーが、未処理小麦粉のグルテン・バイタリティーを100としたときに、70〜90であり、白度が、未処理小麦粉の白度を100としたときに、90〜100であることを特徴とする焙焼小麦粉を提供するものである。   The present invention has been made on the basis of the above findings, and the contained starch is not substantially pregelatinized, and the gluten vitality is 70 to 90 when the gluten vitality of the untreated flour is 100. The whiteness is 90 to 100 when the whiteness of the untreated flour is taken as 100, and the roasted wheat flour is provided.

また、本発明は、上記焙焼小麦粉の製造方法として、乾燥により小麦粉の水分を5質量%未満にした後、この小麦粉を品温100〜140℃で10〜90分間焙焼処理することを特徴とする焙焼小麦粉の製造方法を提供するものである。   Further, the present invention is characterized in that, as a method for producing the roasted wheat flour, after the moisture content of the flour is reduced to less than 5% by mass, the wheat flour is roasted at a product temperature of 100 to 140 ° C. for 10 to 90 minutes. A method for producing roasted wheat flour is provided.

本発明によれば、風味および食感が一層向上した焙焼小麦粉を提供することができる。特に、揚げ物に用いた場合には、衣の風味および食感を向上させ、さらに衣と揚げ物種との結着性も向上させることができる。   According to the present invention, it is possible to provide a roasted wheat flour having a further improved flavor and texture. In particular, when used for fried foods, the flavor and texture of the clothes can be improved, and the binding properties between the clothes and the fried food species can also be improved.

Is more preferable. That is, the whiteness of the roasted flour of the present invention is not significantly different from the whiteness of untreated flour. This means that the degree of roasting treatment is weak. If the whiteness is less than 90 when the whiteness of the untreated flour is taken as 100, a burnt odor will be generated in the garment, which will be uncomfortable.

また、本発明の焙焼小麦粉は、水分が2〜5質量%であることが好ましい。   Moreover, it is preferable that the water | moisture content of the roasted wheat flour of this invention is 2-5 mass%.

本発明の焙焼小麦粉に用いる原料小麦粉は、特に制限はなく、薄力粉、中力粉、強力粉のいずれでもよく、焙焼小麦粉の用途に応じて適宜選択することができる。   The raw material flour used for the roasted wheat flour of the present invention is not particularly limited, and may be any of thin flour, medium flour, and strong flour, and can be appropriately selected according to the use of the roasted flour.

本発明の焙焼小麦粉は、トンカツ、カキフライ、エビフライなどの揚げ物、惣菜パン、ケーキなどの用途に用いることができ、特に揚げ物用として好適である。   The roasted flour of the present invention can be used for fried foods such as tonkatsu, fried oysters and fried shrimp, side dish bread, cakes and the like, and is particularly suitable for fried foods.

本発明の焙焼小麦粉を揚げ物用として用いる場合には、常法に従い、バッター液または打ち粉として用いることができ、その際には、本発明の焙焼小麦粉を含有する揚げ物用ミックス粉としてから用いてもよい。   When the roasted wheat flour of the present invention is used for deep-fried food, it can be used as a batter liquid or dusting powder according to a conventional method, and in that case, as a mixed powder for deep-fried food containing the roasted wheat flour of the present invention. It may be used.

次に、本発明の焙焼小麦粉の製造方法について説明する。本発明の焙焼小麦粉の製造方法は、前述の本発明の焙焼小麦粉の好ましい製造方法である。本発明の焙焼小麦粉の製造方法によれば、本発明の焙焼小麦粉を確実に得ることができる。   Next, the manufacturing method of the roasted flour of this invention is demonstrated. The method for producing the roasted wheat flour of the present invention is a preferred method for producing the roasted wheat flour of the present invention described above. According to the method for producing roasted wheat flour of the present invention, the roasted wheat flour of the present invention can be reliably obtained.

本発明の製造方法においては、先ず、乾燥により小麦粉(原料小麦粉)の水分を5質量%未満にする(乾燥工程)。原料小麦粉としては、通常の小麦粉を使用することができ、前述の通り薄力粉、中力粉、強力粉などが挙げられる。通常の小麦粉は、11〜15質量%程度の水分を含有している。本発明の製造方法においては、この水分を5質量%未満、好ましくは4質量%未満、さらに好ましくは3質量%未満まで乾燥させる。また、コゲ臭防止の観点から、小麦粉の水分は2質量%以上残存させることが好ましい。   In the production method of the present invention, first, the moisture of the flour (raw material flour) is reduced to less than 5 mass% by drying (drying step). As the raw material flour, normal wheat flour can be used, and as mentioned above, thin flour, medium flour, strong flour and the like can be mentioned. Normal wheat flour contains about 11 to 15% by mass of water. In the production method of the present invention, the moisture is dried to less than 5% by mass, preferably less than 4% by mass, and more preferably less than 3% by mass. Further, from the viewpoint of preventing burnt odor, it is preferable to leave 2% by mass or more of the moisture in the flour.

乾燥方法としては、原料小麦粉の含有澱粉をα化させることがなく且つ原料小麦粉のグルテン・バイタリティーおよび白度を大きく変化させない方法が好ましく、具体的には気流式乾燥が好ましい。気流式乾燥の条件は、100〜200℃にて1〜20秒間とすることが好ましい。乾燥方法としては、そのほかに、バンド乾燥機を用いる方法なども挙げられる。   As a drying method, a method in which the starch contained in the raw material wheat flour is not converted into α and the gluten vitality and whiteness of the raw material flour are not significantly changed is preferable. Specifically, airflow drying is preferable. The conditions for airflow drying are preferably 100 to 200 ° C. for 1 to 20 seconds. Other drying methods include a method using a band dryer.

なお、焙焼によっても小麦粉の水分を減少させることはできるが、焙焼により原料小麦粉の水分を5質量%未満とするには長時間を要し、その間に含有澱粉のα化が進み、またグルテン・バイタリティーおよび白度も変化してしまい、さらにはコゲ臭も生じてくる。そのため、最終的に、目的とする特性を有する焙焼小麦粉を得ることができない。これらのことから、本発明においては、乾燥方法として焙焼を採用することはできない。   In addition, although the water | moisture content of wheat flour can also be reduced by baking, it takes a long time to make the water | moisture content of raw material flour less than 5 mass% by baking, and the gelatinization of contained starch advances in the meantime, Gluten vitality and whiteness will also change, and a burnt smell will also occur. Therefore, finally, roasted wheat flour having the desired characteristics cannot be obtained. For these reasons, roasting cannot be employed as a drying method in the present invention.

本発明の製造方法においては、次に、水分5質量%未満となった小麦粉を、品温100〜140℃、好ましくは110〜130℃で、10〜90分間、好ましくは20〜60分間焙焼処理する(焙焼工程)。この焙焼工程により、目的とする焙焼小麦粉が得られる。焙焼は、水分5質量%未満となった小麦粉を、従来の焙焼小麦粉と同様に、連続式運行釜などの焙焼釜で加熱する方法;鉄製トレーに入れ、バンドオーブンなどのオーブン中で加熱する方法;パドルドライヤーなどの加熱装置付きミキサーで加熱する方法などにより行うことができる。   In the production method of the present invention, the flour having a moisture content of less than 5% by mass is then roasted at a product temperature of 100 to 140 ° C., preferably 110 to 130 ° C., for 10 to 90 minutes, preferably 20 to 60 minutes. Process (roasting process). By this roasting step, the intended roasted flour is obtained. Roasting is a method in which the flour with a moisture content of less than 5% by mass is heated in a roasting pot such as a continuous operation kettle in the same manner as conventional roasted flour; Heating method: It can be performed by a method of heating with a mixer with a heating device such as a paddle dryer.

得られた焙焼小麦粉は、その後空冷などの方法により冷却する。粒状になった場合には通常の小麦粉と同程度の粒度まで粉砕することが好ましい。   The obtained roasted wheat flour is then cooled by a method such as air cooling. When it becomes granular, it is preferable to grind to the same particle size as normal wheat flour.

以下、実施例などを挙げて、本発明をさらに詳細に説明するが、本発明はこれらの実施例にのみ限定されるものではない。   EXAMPLES Hereinafter, although an Example etc. are given and this invention is demonstrated further in detail, this invention is not limited only to these Examples.
