- a rapid viscosity measuring device called a rapid visco analyzer (RVA) is known.
- RVA rapid viscosity measuring device
- the flour to be measured is suspended in water, and the viscosity is measured by gradually raising the temperature of the suspension while stirring.
- RVA viscosity characteristics of wheat flour vary depending on the type of flour, but the RVA viscosity characteristics common to many flours do not show a significant change in viscosity at a relatively low temperature at the beginning of temperature rise, but suddenly increase from a certain temperature. The viscosity starts to increase, and after reaching a peak (maximum viscosity), it decreases. In such RVA viscosity characteristics, the start temperature of sudden viscosity increase is called “gelatinization start temperature”, and the maximum viscosity is called “RVA peak viscosity”.
- the RVA viscosity characteristics of wheat flour largely depend on the gelatinization characteristics when the starch in the flour is heated to become paste, but wheat flour is a component that affects the viscosity characteristics. Since a plurality of components are included, the RVA viscosity characteristic of the flour is determined by the comprehensive action of the plurality of components.
- the inventors of the present invention used various flours as raw materials, applied heat treatment and other reforming treatments to the raw flours under various conditions, and examined the suitability of the resulting modified flours for fried foods. .

That is, the modified wheat flour for fried food of the present invention is obtained by subjecting raw material flour, that is, wheat flour before the modification treatment, to heat treatment as a modification treatment. However, as long as the raw material flour is simply heated, the modified wheat flour for fried food of the present invention, that is, a fried food having good dispersibility in water, excellent workability, and a crispy texture. In order to obtain the modified wheat flour for fried food of the present invention, as described above, the RVA peak viscosity of the modified flour and the paste before and after the heat treatment are not necessarily obtained. It is important to adjust the temperature so as to be within a specific range.
- the RVA peak viscosity is 3500 to 7000 mPa ⁇ s.
- the RVA peak viscosity of the modified flour particularly affects the texture of the clothes in the fried food obtained by using this, and the RVA peak viscosity is in the range of 3500 to 7000 mPa ⁇ s.
- a fried food with a crispy texture can be obtained. If the RVA peak viscosity of the modified flour is less than 3500 mPa ⁇ s, the clothing tends to have a sticky texture, and if it exceeds 7000 mPa ⁇ s, the clothing tends to have a hard texture.

Abstract
Description
また特許文献2には、熱処理した小麦粉、酸化澱粉及びショ糖脂肪酸エステルを含有するフライ用衣組成物が記載されており、これによれば、経時劣化耐性、レンジ耐性に優れた天ぷら等のフライ食品が得られるとされている。
また特許文献3には、揚げ物用熱処理小麦粉として、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が未処理小麦粉の90~98%で、グルテン膨潤度が105~155%であるものが記載されており、これによれば、油ちょう直後のみならず、冷めた場合でも衣がサクサクした食感を有する天ぷらが得られるとされている。
また特許文献4には、RVAのピーク粘度が4700mPa・s以上の小麦粉を加熱処理してなり、グルテンバイタリティが30%以下である揚げ物用加熱処理小麦粉が記載されている。特許文献4記載の揚げ物用加熱処理小麦粉は、天ぷら等の揚げ物の風味及び食感の向上と共に、衣の具材に対する結着性の向上を課題としたもので、前記の原料小麦粉のRVAのピーク粘度4700mPa・s以上という特定範囲は、結着性と食感とのバランスの観点から採用されたものである。
測定装置に付属のアルミ缶(測定対象物の収容容器)に、測定対象の小麦粉4g及び蒸留水を、小麦粉との合計重量で29gになるように入れた後、さらにパドル(攪拌子)を入れ、タワーにセットする。尚、アルミ缶に入れる小麦粉の量に関し、小麦粉の水分値が14%含有時に4g必要であり、水分値が異なる際は小麦粉の固形分が3.44gとなるように換算する。そして、アルミ缶内のパドルを回転数160rpm/minで回転させながら、該アルミ缶を加熱してその内容物(小麦粉懸濁液)の温度を上昇させつつ該内容物の粘度を測定する。このときのアルミ缶内容物の加温上昇条件は、はじめにアルミ缶内容物の品温を50℃で1分間保持した後、7分30秒をかけて95℃まで昇温させ、同温度で5分間保持し、次いで7分30秒をかけて50℃まで降温した後、同温度で2分間保持する条件とする。そして、斯かるアルミ缶加熱処理中の内容物の粘度曲線を得、該粘度曲線に基づいて、粘度が急激な上昇を開始した時点の温度を「糊化開始温度」、最高粘度を「RVAピーク粘度」とする。
4)被搬送物の載置面を加熱可能な加熱手段を具備するベルトコンベアの該載置面に原料小麦粉を載置してこれを移送しつつ、その移送中に該加熱手段によって該原料小麦粉を加熱する熱処理。斯かるベルトコンベアとしては、例えば、加熱手段を具備しない通常のベルトコンベアにおける被搬送物の載置面に、ヒートパッド等の別体の加熱手段を配置したものを用いることができる。
