Everything about Whole Wheat Flour totally explained
Whole wheat flour is a
powdery substance derived by
grinding or mashing the
wheat's whole grain. It is used in
baking but typically added to other "white"
flours to give nutrition (especiall
fiber and
protein), texture, and body to the finished product.
Overview
The word "whole" refers to the fact that all of the grain (
bran,
germ, and
endosperm) is used and nothing is lost in the process of making the flour. This is in contrast to
white, refined flours, which contain only the endosperm. Because the whole flour contains the remains of all of the grain, it has a textured, brownish appearance.
Benefits
Whole wheat flour is more nutritious than refined white flour. In a process called
food fortification, some
micronutrients are added back to the white flour (required by law in some jurisdictions) though. Fortified white wheat flour does not, however, contain the
macronutrients of the wheat's bran and germ (especially
fiber and
protein). Whole wheat is a good source of
calcium,
iron, fiber and other minerals like
selenium.
Drawbacks
Whole wheat flour has a shorter
shelf life than white flour, as the higher
oil content leads to
rancidification. It is also more expensive.
Usually, whole wheat flour isn't the main ingredients of baked goods, as it adds a certain "heaviness" which prevents them from rising as well as white flours. This adds to the cost per volume of the baked item as it requires more flour to obtain the same volume, due to the fewer and smaller air pockets trapped in the raised goods. Thus, many baked goods advertised as whole wheat are not entirely whole wheat; they may contain some refined white wheat, as long as the majority of the wheat used is whole wheat.
Nevertheless, it's possible to make a high-rising, light loaf of 100% whole wheat
bread, so long as one increases the water content of the
dough (the bran and germ in whole wheat absorb more water than plain white flour), kneads the dough for a longer period of time to develop the gluten adequately, and allows for a longer rise before shaping the dough. Some bakers let the dough rise twice before shaping. The addition of fats, such as butter or oil, and milk products (fresh milk, powdered milk, buttermilk, yogurt, etc.) can also greatly assist the rise.
White whole wheat
White whole wheat flour is flour produced from soft white wheat varieties. Instead of being made from red wheat, the most common type in the
United States, like most whole wheat flour, white whole wheat is made from white wheat, more common in the
United Kingdom. The difference is that soft white wheat has a lower gluten content as well as lacking the
tannins and
phenolic acid that red wheat does, causing white whole wheat to appear and taste more like refined red wheat; it's whitish in color and doesn't taste bitter.
Along with a reduced gluten content, soft white wheat generally contains a lower protein content (between 9% and 11%) when compared with harder wheats like red (15%-16% protein content) or golden wheat.
