Stoneground flour

Last updated

Stoneground flour is whole grain flour produced by the traditional process of grinding grain between two millstones. This is in contrast to mass-produced flours which are generally produced using rollers. The process leaves the wheatgerm more intact than roller processes for producing wholemeal flour, [1] the larger pieces of bran and other components of the grain cause it to have a coarser texture but greater flavour. This affects its ability to rise, however it can produce a more satisfying texture for some baked products. [2] The inclusion of more bran and intact wheatgerm in the flour means that it is often credited with significant health benefits. [3]

In the USA flour only has to 'pass between stones' once during its manufacture to be regarded as stoneground, and it has been claimed that a significant proportion of flour sold as stoneground in the USA has not been processed in this way, being ordinary roller-ground wholemeal. [4]

White rice is milled rice that has had its husk, bran, and germ removed. This alters the flavor, texture and appearance of the rice and helps prevent spoilage, extend its storage life, and makes it easier to digest. After milling (hulling), the rice is polished, resulting in a seed with a bright, white, shiny appearance.

<span class="mw-page-title-main">White bread</span> Type of bread made from white wheat flour

White bread typically refers to breads made from wheat flour from which the bran and the germ layers have been removed from the whole wheatberry as part of the flour grinding or milling process, producing a light-colored flour. This milling process can give white flour a longer shelf life by removing the natural oils from the whole grain. Removing the oil allows products made with the flour, like white bread, to be stored for longer periods of time avoiding potential rancidity.

Wheat flour is a powder made from the grinding of wheat used for human consumption. Wheat varieties are called "soft" or "weak" if gluten content is low, and are called "hard" or "strong" if they have high gluten content. Hard flour, or bread flour, is high in gluten, with 12% to 14% gluten content, and its dough has elastic toughness that holds its shape well once baked. Soft flour is comparatively low in gluten and thus results in a loaf with a finer, crumbly texture. Soft flour is usually divided into cake flour, which is the lowest in gluten, and pastry flour, which has slightly more gluten than cake flour.

<span class="mw-page-title-main">Cereal germ</span> Reproductive part of a grass seed

The germ of a cereal is the reproductive part that germinates to grow into a plant; it is the embryo of the seed. Along with bran, germ is often a by-product of the milling that produces refined grain products. Cereal grains and their components, such as wheat germ oil, rice bran oil, and maize bran, may be used as a source from which vegetable oil is extracted, or used directly as a food ingredient. The germ is retained as an integral part of whole-grain foods. Non-whole grain methods of milling are intended to isolate the endosperm, which is ground into flour, with removal of both the husk (bran) and the germ. Removal of bran is aimed at producing a flour with a white rather than a brown color, and eliminating fiber, which reduces nutrition. The germ is rich in polyunsaturated fats and so germ removal improves the storage qualities of flour.

A middlings purifier is a device used in the production of flour to remove the husks from the kernels of wheat. It was developed in Minnesota by Edmund LaCroix, a French inventor hired by Cadwallader C. Washburn and George Christian of the Washburn "A" Mill. It was developed to complement the emerging roller mill technique of the late 19th century, which used corrugated metal rollers instead of abrasive grindstones to grind wheat into flour. The middlings purifier was used to separate the bran from the usable part of the flour. The machine developed by LaCroix passed the partially ground middlings over a screen, and a stream of air blew away the particles of bran.

Whole wheat bread or wholemeal bread is a type of bread made using flour that is partly or entirely milled from whole or almost-whole wheat grains, see whole-wheat flour and whole grain. It is one kind of brown bread. Synonyms or near-synonyms for whole-wheat bread outside the United States are whole grain bread or wholemeal bread. Some regions of the US simply called the bread wheat bread, a comparison to white bread. Some varieties of whole-wheat bread are traditionally coated with whole or cracked grains of wheat, though this is mostly decorative compared to the nutritional value of a good quality loaf itself.

A gristmill grinds cereal grain into flour and middlings. The term can refer to either the grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding.

A Unifine mill is a single one-pass impact milling system which produces ultrafine-milled whole-grain wheat flour that requires no grain pre-treatment and no screening of the flour. Like the grist or stone mills that had dominated the flour industry for centuries, the bran, germ, and endosperm elements of grain are processed into a nutritious whole wheat flour in one step. Consumers had accepted whole wheat products produced by grist or stone mills. The flour produced by these mills was quite coarse as they included the bran and the germ elements of the grain.

<span class="mw-page-title-main">Whole-wheat flour</span> Basic food ingredient, derived by grinding or mashing the whole grain of wheat

Whole-wheat flour or wholemeal flour is a powdery substance, a basic food ingredient, derived by grinding or mashing the whole grain of wheat, also known as the wheatberry. Whole-wheat flour is used in baking of breads and other baked goods, and also typically mixed with lighter "white" unbleached or bleached flours to restore nutrients, texture, and body to the white flours that can be lost in milling and other processing to the finished baked goods or other food(s).

The Roller Mill was created by Hungarian bakers in the late 1860s and its popularity spread worldwide throughout the 1900s. Roller mills now produce almost all non-whole grain flour. Enriched flour is flour that meets an FDA standard in the United States. Roller milled white enriched flour makes up over 90% of the flour that comes out of the United States.

Flour extraction is the common process of refining Whole Grain Flour first milled from grain or grist by running it through sifting devices, often called flour dressers.
