Description

The present invention relates to a pastry food flour dough having good workability and a pastry dough manufactured using the pastry food flour dough.
The present invention also relates to pastry foods that have a good texture and texture.

  Pastry foods such as croissants, Danish and pies are produced by baking dough in which an oil and fat composition such as sheet margarine is folded in layers. Pastry foods are characterized in that the dough swells in layers when baked, so the dough floats well, has a voluminous feel, and the texture is soft and soft.

  Moreover, the dough which folds the fats and oils composition used for manufacture of pastry food is repeatedly folded and rolled a plurality of times. Therefore, the fabric to be folded needs to have good extensibility in terms of workability.

  In order to improve the workability at the time of manufacture of pastry foods, the dough floating of pastry foods, and the texture, methods for improving the dough into which the oil and fat composition is folded have been proposed. Specifically, a method using four types of emulsifiers (Patent Document 1), a method using a complexing agent of gelling agent, milk protein and water (Patent Document 2) are proposed.

However, the method of Patent Document 1 has a problem that the taste of pastry foods is deteriorated because a large amount of emulsifier is blended. Moreover, since the method of patent document 2 uses a special composite_body | complex, there existed a problem that acquisition was difficult.
Therefore, the methods of Patent Documents 1 and 2 have not been satisfactory as a method for improving workability during the manufacture of pastry foods, floating of dough of pastry foods, and texture.
