Description

本発明はソフトでかつもち食感を有する油ちょうベーカリー食品の配合及び製造方法に関する。 The present invention relates to the formulation and manufacturing method of fried bakery foods that have a soft and chewy texture.

米粉は餅、団子などの原材料として古くから使用されていると同時に、ベーカリー製品などにも使用されている原材料である。ドーナツ等の油ちょうベーカリー食品においても特徴ある食感を出すために米粉を使用した製品が上市されている。米粉を使用したドーナツ等の油ちょうベーカリー食品では硬い食感になりやすい。
その対策として、従来、特許文献1に報告されている米粉100質量部に対して小麦粉を0.1~5.0質量部配合する技術がある。しかし、この技術では形状の不安定さから小麦粉を米粉に対して0.1~5.0質量部までしか配合することができず、よりソフトな米粉ドーナツを製造することは難しかった。
特許文献2には、小麦粉および/または澱粉に、もち米粉、油脂ならびにα化澱粉および/またはα化小麦粉を配合し、イーストを加えて、イースト発酵させ、ついで圧扁焼成することを特徴とするもち米利用菓子の製造方法が開示されている。製造されたもち米利用菓子は、従来のもち米利用菓子にない口当たりがソフトでもちもちして、歯切れよく口溶けの良い食感を有するが、依然としてソフトさ及びもち感が十分ではなかった。
Rice flour has long been used as a raw material for mochi (rice cakes) and dango (rice dumplings), and is also used in bakery products. In fried bakery foods such as donuts, products using rice flour to give them a distinctive texture are also on the market. However, fried bakery foods such as donuts that use rice flour tend to have a hard texture.
As a countermeasure, there is a conventional technique for blending 0.1 to 5.0 parts by mass of wheat flour with 100 parts by mass of rice flour, as reported in Patent Document 1. However, with this technique, wheat flour can only be blended up to 0.1 to 5.0 parts by mass with rice flour due to instability in the shape, making it difficult to produce softer rice flour donuts.
Patent Document 2 discloses a method for producing glutinous rice confectionery, which comprises blending glutinous rice flour, oil and fat, and pregelatinized starch and/or pregelatinized wheat flour with wheat flour and/or starch, adding yeast, yeast fermenting, and then pressing and baking. The produced glutinous rice confectionery has a soft and chewy texture not found in conventional glutinous rice confectionery, and has a crisp texture that melts in the mouth, but the softness and chewiness are still insufficient.

<油ちょうベーカリー食品用ミックス粉>
本発明の油ちょうベーカリー食品用ミックス粉は、米粉と小麦粉を少なくとも含み、米粉と小麦粉の合計100質量部に対し、α化澱粉を2~28質量部含み、さらに、米粉と小麦粉の合計質量に対し小麦粉が53質量%以下の量で含まれている。
<Fried bakery food mix flour>
The flour mix for fried bakery foods of the present invention contains at least rice flour and wheat flour, contains 2 to 28 parts by mass of gelatinized starch per 100 parts by mass of the total of the rice flour and wheat flour, and further contains wheat flour in an amount of 53% by mass or less relative to the total mass of the rice flour and wheat flour.

(油ちょうベーカリー食品)
本明細書において油ちょうベーカリー食品は、油ちょう調理される、米粉を用いて製造されるパンや菓子類を意味する。例えば、ドーナツ、チュロス、サーターアンダギー、揚げパンなどが含まれる。好ましくは揚げパン、ドーナツ等が挙げられる。揚げパンとは、パン生地を成形して油ちょうする製品である。ドーナツは、ドーナツ生地を成形して油ちょうする製品であり、例えば、ケーキドーナツ等を含む。
(Fried bakery foods)
In this specification, fried bakery foods refer to breads and confectioneries made from rice flour that are fried. Examples include donuts, churros, sata andagi, and fried bread. Preferred are fried bread and donuts. Fried bread is a product made by shaping bread dough and frying it. Donuts are a product made by shaping donut dough and frying it, and include, for example, cake donuts.

(米粉)
本発明の油ちょうベーカリー食品用ミックス粉は、米粉を必須成分として含む。米粉はうるち米粉を含むことが好ましい。もち米粉では所定の効果が得られにくいため、用いる米粉はうるち米粉からなることがより好ましい。
米粉の主な製造方法として、ロール粉砕法、気流粉砕法がある。ロール粉砕では、粒度が粗く損傷澱粉率が高い米粉が得られる。気流粉砕では、粒度が細かく損傷澱粉率が低い米粉が得られる。
本発明において米粉の損傷澱粉率や粒度を限定することなく使用できるが、損傷澱粉率が9~14%のものが好ましく、粒度(メジアン径)が90~120μmのものが好ましい。かかる損傷澱粉率や粒度の米粉を少なくとも30質量%程度含む米粉を用いることが好ましい。
(rice flour)
The flour mix for fried bakery foods of the present invention contains rice flour as an essential component. The rice flour preferably contains non-glutinous rice flour. Since it is difficult to obtain the desired effect with glutinous rice flour, it is more preferable that the rice flour used is non-glutinous rice flour.
The main methods for producing rice flour are roll milling and airflow milling. Roll milling produces rice flour with a coarse grain size and a high rate of damaged starch. Airflow milling produces rice flour with a fine grain size and a low rate of damaged starch.
In the present invention, rice flour can be used without any restrictions on the damaged starch rate or particle size, but rice flour with a damaged starch rate of 9 to 14% and a particle size (median diameter) of 90 to 120 μm is preferred. It is preferable to use rice flour containing at least about 30% by mass of rice flour with such a damaged starch rate and particle size.

(小麦粉)
本発明の油ちょうベーカリー食品用ミックス粉は、小麦粉を必須成分として含む。
小麦粉は、米粉および小麦粉の合計質量に対して、53質量%以下の量で含まれる。0.3~53質量%の範囲で含まれていることが好ましく、0.5~50質量%であることがより好ましく、5~40質量%であることがよりさらに好ましい。小麦粉の配合量は多いほど食感はソフトになるため好ましいが、配合量が多くなりすぎると、もち感が弱くなるため、かかる範囲が好ましい。
(flour)
The flour mix for fried bakery foods of the present invention contains wheat flour as an essential ingredient.
Wheat flour is contained in an amount of 53% by mass or less based on the total mass of rice flour and wheat flour. It is preferably contained in the range of 0.3 to 53% by mass, more preferably 0.5 to 50% by mass, and even more preferably 5 to 40% by mass. The more wheat flour is contained, the softer the texture becomes, which is preferable, but if the amount is too high, the chewiness becomes weak, so this range is preferable.

(α化澱粉)
α化とは一般には澱粉を水と加熱することで、澱粉分子が規則性を失い、糊状(α状)になることである。本発明では、澱粉と水を混ぜて加熱し、糊状になった澱粉を乾燥させて粉末化したものをα化澱粉として使用した。
α化澱粉であれば限定することなくいずれの種類を用いてもよい。例えば、タピオカ澱粉、コーン澱粉、ワキシーコーン澱粉、小麦澱粉、馬鈴薯澱粉、米粉澱粉、もち米粉澱粉等のα化澱粉が挙げられる。これらを複数種類配合したものを使用してもよい。前述のα化澱粉は市販されているものを用いることができる。
α化澱粉は、米粉と小麦粉の合計100質量部に対し2~28質量部添加する。2.5~25質量部が好ましく、10~20質量部がより好ましく、13~17質量部がよりさらに好ましい。かかる範囲の量でα化澱粉を配合することにより、米粉に対し小麦粉を従来より多く配合することができ、その結果、もち感がありつつソフトな食感を提供することができる。
α化澱粉は、2質量部を下回ると米粉および小麦粉のα化に必要な水分が不足し、非常に硬い食感となる。28質量部を上回るとフライ後のしぼみが生じて外観が劣るとともに、食感にやや弾力が出て劣る。
(gelatinized starch)
Gelatinization is generally a process in which starch molecules lose their regularity and become pasty (alpha-shaped) by heating starch with water. In the present invention, starch was mixed with water, heated, and the pasty starch was dried and powdered, and used as the gelatinized starch.
Any type of pregelatinized starch may be used without any limitation. Examples of pregelatinized starches include tapioca starch, corn starch, waxy corn starch, wheat starch, potato starch, rice flour starch, glutinous rice flour starch, etc. A mixture of multiple types of these may also be used. The above-mentioned pregelatinized starch may be a commercially available product.
The amount of gelatinized starch added is 2 to 28 parts by mass per 100 parts by mass of the total of rice flour and wheat flour, preferably 2.5 to 25 parts by mass, more preferably 10 to 20 parts by mass, and even more preferably 13 to 17 parts by mass. By adding gelatinized starch in an amount within this range, it is possible to add more wheat flour to the rice flour than before, and as a result, it is possible to provide a chewy yet soft texture.
If the amount of pregelatinized starch is less than 2 parts by mass, the moisture required for pregelatinization of the rice flour and wheat flour is insufficient, resulting in a very hard texture, whereas if the amount is more than 28 parts by mass, the product will shrink after frying, resulting in a poor appearance, and the texture will be somewhat elastic and poor.

(その他の成分について)
本発明の油ちょうベーカリー食品用ミックス粉は、米粉及びα化澱粉以外に、糖類、油脂、膨張剤、色素や調味料等の添加剤等を含んでいてもよい。なお、本発明の油ちょうベーカリー食品用ミックス粉は少なくとも米粉、小麦粉及びα化澱粉を含んでいればよいが、米粉、小麦粉及びα化澱粉は、一つの均一な混合組成物として存在していてもよく、または別々に用意されており、生地製造時に混合されるものであってもよい。他の成分や添加剤についても同様に一つの混合物中に存在していてもよく、また別々に用意されており、生地製造時に混合されるものであってもよい。

The types of sugars that can be used are not particularly limited, and include monosaccharides such as glucose and fructose, sucrose (white sugar such as caster sugar, granulated sugar, brown sugar, and molasses sugar such as brown sugar), and lactose such as lactose. Any edible sweet powdered sugar such as saccharide can be used. Granulated sugar is more preferable from the viewpoint of taste and melting in the mouth. The blending amount is preferably within the range of 5 to 100 parts by weight, more preferably about 20 to 80 parts by weight, and even more preferably about 30 to 70 parts by weight, based on a total of 100 parts by weight of rice flour and wheat flour.

生地性や食感の調整にショートニングやサラダ油などの油脂類を配合してもよい。 Fats and oils such as shortening and salad oil may be added to adjust the dough properties and texture.

膨張剤は通常、生地を膨張させてふんわり感を出すために油ちょうベーカリー食品の配合に入れる。本発明では、米粉と小麦粉の合計100質量部に対し、膨張剤を1.5~6.0質量部まで入れても良い。量が少ないとフライ後にしぼんで表面のしわが大きくなる傾向にある。量が多すぎると、膨張剤の味(えぐ味)が出る。 Leavening agents are commonly included in the formulation of baked goods to expand the dough and create a fluffy texture. In the present invention, 1.5 to 6.0 parts by mass of a leavening agent may be added to a total of 100 parts by mass of rice flour and wheat flour. If the amount is small, it will tend to shrink after frying and the wrinkles on the surface will become larger. If the amount is too large, the taste of the leavening agent (harsh taste) will appear.

本発明の油ちょうベーカリー食品用ミックス粉には、必要に応じて、色素、調味料、香辛料、香料などの副資材や添加物を使用することができる。食塩を加えてもよい。食塩は食味を出すことを目的に配合してもよく、食味に合わせて調整可能である。

The amount of water in each Example and Comparative Example was adjusted to match the viscosity of the dough (viscosity 520 to 580 mPa·s).
The resulting dough was cut with a donut cutter and fried. The plunger used was a 1-7/8 plain plunger, and the dough weight was 66 g. The dough was fried at 190°C for 3 minutes, and then turned over and removed from the oil.
The rice flour used was Takasago 117 (manufactured by Nippon Flour Mills Co., Ltd.), a roll-milled rice flour with a coarse particle size (particle size: 90-120 μm) and a high rate of damaged starch (9-14%). The gelatinized starch used was Pregel VA70T (manufactured by Matsutani Chemical Industry Co., Ltd.), a gelatinized tapioca starch.
Sensory evaluation and appearance evaluation were performed according to the evaluation criteria in Table 1. A similar formulation to Example 5 in JP 2013-081423 A was evaluated by 10 panelists using a standard score of 3 points (Comparative Example 1). The "height" and "diameter" in the appearance evaluation criteria refer to the thickness and diameter of the donut, respectively, and were evaluated as being larger or smaller than the standard donut.
