Flour represents a processed commodity obtained through the mechanical grinding—typically via industrial milling processes—of either the starchy endosperm component alone (commonly referred to as the kernel’s white interior) or the entire, unrefined cereal grain, which exhibits a substantially greater concentration of bioactive nutritional compounds. Its versatile applications extend far beyond conventional bread-making in its myriad textural variations, encompassing the preparation of elaborate, spice-infused holiday confections as well as sweet dessert items such as crisp cookies or airy cupcakes. Moreover, it serves as an indispensable culinary ingredient in crafting delicate, fluffy pancakes or moist flatbreads that can significantly enhance a nutritionally balanced breakfast meal. While the majority of individuals have been familiar with this staple since early childhood and incorporate it into daily routines, few fully comprehend the profound impact that flour-derived food products may exert on bodily functions and the preservation of optimal health across multiple physiological dimensions.
Sugar dough (carbohydrates)
They make up about... 70% of the mass of both wheat flour and rye flour. The main carbohydrate composed is starch accumulated in wheat. The more starch, the less starch in the flour, and thus the lower nutrient content. The starch is a good source of energy.
It's a protein dough
The basic source of nutritional value necessary for proper functioning. In flour we find about 10% of proteins which, due to their plant origin, are part of the incomplete source of essential amino acids. For this reason it is worth combining baking with products of animal origin i.e. meat or fermented dairy beverages. The proteins present in flour can be divided into simple and complex. Simple proteins are mainly gluten and gluten, which together form the complex protein uten.
It's a mixture of vitamins and minerals
The mineral content of the flour increases with the value of the extract. Clear flour contains small amounts of ash, unlike dark high extract flour, which also includes, in addition to the ground grain, the particles of the kernels and the embryos. Flour is a valuable source of calcium (mainly wheat), phosphorus (especially wheat flour), iron (both wheat and rye flours), magnesium, sodium and copper, as well as vitamins from group B mainly thiamine.
It's soft, it's greasy
Flour contains glycerides, phospholipids and plant sterols. The source of the fat is a particularly small grain embryo (about 12%), which reaches only the dark high-cut flour, and to a lesser extent the grain itself (approximately 2 3%).. The overall lipid content of the flour is low an average of 1.5% and it is a vegetable fat and therefore does not contain cholesterol.. It should be noted that poorly processed flour therefore has a shorter shelf life as it tends to become fat-filled during longer storage and food processing.
