Editing Flour (section)

=== Gluten flour ===
Gluten flour is refined gluten protein, or a theoretical 100% protein (though practical refining never achieves a full 100%). It is used to strengthen flour as needed.  For example, adding approximately one teaspoon per cup of AP flour gives the resulting mix the protein content of bread flour.  It is commonly added to whole grain flour recipes to overcome the tendency of greater fiber content to interfere with gluten development, needed to give the bread better rising (gas holding) qualities and chew.
