  An object of the present invention is to provide a flour composition for fried foods that can use a roasting process to obtain a fried food that is crispy and crispy and has good crispness and little deterioration over time. .

As a result of intensive studies to achieve the above-mentioned object, the present inventors have previously studied before the roasting process the flour and starch that have been roasted separately and then mixed and used as necessary. When mixing and roasting the mixture, it was surprisingly found that better secondary processability can be obtained than when roasting wheat flour and starch separately and then mixing, and the present invention has been completed.
Accordingly, the present invention provides a flour composition for frying food, wherein wheat flour and starch are mixed such that the ratio of wheat flour to starch is 80:20 to 20:80, and the mixture is roasted. is there.
Moreover, roasting conditions are the said methods characterized by heating at 120 to 160 degreeC for 1 to 3 hours.
Moreover, it is mixed powder containing the flour composition for fried foods.

  By using the flour composition for fried food of the present invention, it is possible to obtain a fried food that is crispy and crispy and has a good crispness, has a bright burnt color, and little quality deterioration over time.

Hereinafter, the present invention will be described in detail.
In the present invention, fried food refers to food that is fried and heated, such as tempura, fried chicken, croquettes, and fried chicken.
These are characterized by adding a dough or powder such as flour to the material and frying.
Usually, meat, seafood, vegetables, etc. are used as raw materials.
In any case, the food is characterized by being fried, and is characterized by a crispy feeling, a fresh feeling, a mouth-melting feeling and the like.

The wheat flour used in the present invention can be appropriately selected from thin wheat flour, medium wheat flour, and strong wheat flour according to the texture and taste of the desired product.
Whole grain powder can also be used when seeking a strong texture and flavor.
These can be used alone or in admixture of two or more.

  The starch that can be used in the present invention is not particularly limited as long as it is an edible starch, and corn starch, waxy corn starch, wheat starch, potato starch, tapioca starch, rice starch, sago starch and the like can be used.

In the present invention, the ratio of wheat flour to starch is in the range of 80:20 to 20:80, respectively.
If the ratio is more than that, the effect of roasting the mixture cannot be obtained.
Within this range, the blending ratio of wheat flour and starch can be adjusted according to the quality required for the final product.
For example, the starch ratio is increased for deep-fried food due to its hard and crunchy texture, and the flour ratio is increased for tempura with a fresh texture.

Any type of machine can be used for the roasting treatment as long as the temperature of the grains rises, such as a normal dryer, a type that blows hot air, and a bakery oven for confectionery.
For example, a mixture of wheat flour and starch previously packed in a metallic container such as a baking mold for bread, and then covered and baked in a confectionery baking oven or spread the mixture on a baking baking baking sheet A method of roasting in a hot air dryer can be used.
For large-scale production, a band oven or the like in which the lower firing surface is heated can be used.
Differences in water loss caused by different dry heat methods do not affect workability.

The roasting conditions are preferably 120 ° C. to 160 ° C. and heated for 1 to 3 hours. More preferably, it is 125 to 145 ° C. for 1 to 2 hours.
A roasting temperature of less than 120 ° C. is not preferred because roasting is insufficient and there is a tendency to lack crispyness.
When the roasting temperature exceeds 160 ° C., there is a tendency for a burning odor to occur, which is not preferable.
A roasting time of less than 1 hour is not preferred because roasting is insufficient and there is a tendency of lack of crispness.
A roasting time of 3 hours or more is not preferable because there is a tendency for a burning odor to occur.
In the present invention, “OO” to “ΔΔ” refer to “OO” to “ΔΔ”, for example, “1 to 3” means 1 to 3 inclusive.
