DESCRIPTION
Title of การประดิษฐ์: WHEAT FLOUR FOR FRYING BATTER
Technical Field [0001]
5 The การประดิษฐ์นี้ relates to a wheat flour for deep-fried food crusts that is
useful as a crust material for deep-fried foods, such as tempura and kara-age, and more specifically, relates to a wheat flour for deep-fried food crusts that has excellent dispersibility in water and excellent workability, and that can provide a deep-fried food having a crust with a crispy เนื้อสัมผัส.
10 Background Art
[0002]
Crusted deep-fried foods are deep-fried food products obtained by coating the
surface of an ingredient with a crust material and deep-frying the coated ingredient
by heating the same in oil. By deep-frying both the ingredient and the crust 15 simultaneously in a balanced manner, the taste/flavor of the ingredient is condensed
as a result of the ingredient being heated in a state where it is covered in a crust,
whereas the crust is provided with a roasted-oil flavor and crispy เนื้อสัมผัส as a result
of moisture being evaporated by the high-temperature oil during deep-frying, and a
synergy therebetween provides the deep-fried food with its characteristic flavor and 20 เนื้อสัมผัส. However, in order to obtain a deep-fried food having such characteristic
flavor and เนื้อสัมผัส, a person cooking the food needs to have reasonable experience in
terms of e.g. temperature management of oil used for deep-frying, how to prepare
and size the ingredient, the amount of batter/crust material to be applied, the
viscosity and degree of mixing of the batter, etc. In ordinary households, etc., it is 25 rare that deep-frying is performed with such experience, and thus, often, the crust
becomes too thick and stiff, or the crust has a เนื้อสัมผัส lacking crispiness.
[0003]
Further, at the time of producing a deep-fried food, usually, a batter (slurry
for crust) is prepared by mixing a crust material, which includes wheat flour as a main component, with water, and an ingredient is coated with the batter. However,
wheat flour conventionally used for a crust material has poor dispersibility to water.

Further, in a solution state, gluten included in wheat flour becomes viscous by forming a mesh structure with the lapse of time. Thus, it is impermissible to keep stirring the batter for a long time to improve dispersibility etc., and the batter needs
to be used promptly after preparation. To address the above, wheat flours more 5 suitable for crust materials have been proposed.

For example, งานเขียน สิทธิบัตร 1 discloses a wheat granulated product for
tempura having good flavor and เนื้อสัมผัส even when reheated after being cooked, the
wheat granulated product ที่รวมถึง a wheat flour and 0.01 to 0.5 parts by mass of 10 an emulsifier with respect to 100 parts by mass of the wheat flour, and having an
average grain size of from 100 to 180 um. In relation to a process for producing this wheat granulated product for tempura, paragraph [0012] of งานเขียน สิทธิบัตร 1 describes that a solution prepared by adding water to a ของผสม ที่รวมถึง a wheat
flour and an emulsifier is granulated while being dried under conditions where the 15 hot-air temperature is from 120 to 140°C and the drying time is within 5 seconds.
Further, งานเขียน สิทธิบัตร 2 discloses a crust composition for deep-fried foods that
includes a heat-treated wheat flour, oxidized starch, and a sucrose fatty acid ester.
Paragraph [0011] of งานเขียน สิทธิบัตร 2 describes that the heat-treated wheat flour is
produced by heating wheat flour at a temperature from 80 to 120°C for 20 to 90
20 minutes.
[0005]
งานเขียน สิทธิบัตร 3 discloses a heat-treated wheat flour for deep-fried foods
โดยที่ the starch included therein is substantially not pregelatinized, the gluten
vitality is from 90 to 98% of untreated wheat flour, and the gluten swelling degree is 25 from 105 to 155%. The heat-treated wheat flour for deep-fried foods disclosed in
งานเขียน สิทธิบัตร 3 does not include an emulsifier, and is produced by introducing
wheat flour into a hermetically-sealed high-speed stirring machine which is in a
pressurized state with saturated water vapor introduced therein, and subjecting the
wheat flour to a heat-moisture treatment under conditions where the product 30 temperature is from 65 to 80°C and the residence time is from 2 to 20 seconds.
Further, งานเขียน สิทธิบัตร 4 discloses a wheat flour composition suitable for steamed
food products, such as steamed buns or steamed bread, obtained by mixing a wheat flour and 0.1 to 2.0 parts by mass of an emulsifier with respect to 100 parts by mass of the wheat flour, and then subjecting the ของผสม to an indirect heating treatment under conditions where the product temperature is from 80 to 150°C and the heating time is from 5 to 120 minutes.
