A bleaching agent affects the carotenoids responsible for the natural colour of the flour a "maturing" agent also affects gluten development. "Refined" flour has had the germ and bran, containing much of the nutritional fibre and vitamins, removed and is often referred to as "white flour".īleached flour is artificially aged using a "bleaching" agent, a "maturing" agent, or both. "Bleached flour" is "refined" flour with a chemical whitening (bleaching) agent added. Heat-processed flour is flour where the germ is first separated from the endosperm and bran, then processed with steam, dry heat or microwave and blended into flour again. Degermation started in densely populated areas and took approximately one generation to reach the countryside. Without the germ, flour cannot become rancid. As vitamins, micronutrients and amino acids were completely or relatively unknown in the late 19th century, removing the germ was an effective solution. In the late 19th century, this process was too short for an industrial production and distribution cycle. Depending on climate and grain quality, this process takes six to nine months. This occurs when grain is milled the fatty acids oxidize and flour starts to become rancid. The reason for the limited shelf life is the fatty acids of the germ, which react from the moment they are exposed to oxygen. Transportation distances and a relatively slow distribution system collided with natural shelf life. In the 1940s, mills started to enrich flour and folic acid was added to the list in the 1990s.Īn important problem of the industrial revolution was the preservation of flour. In the 1930s, some flour began to be enriched with iron, niacin, thiamine and riboflavin. In 1786, at the beginning of the Industrial Era, the first steam-powered flour mill, Albion Mills, Southwark, was completed in London. The Romans were the first to grind seeds on cone mills. In 2018, archaeologists reported finding evidence of bread making at Shubayqa 1, a Natufian hunter-gatherer site more than 14,000 years old in northwest Jordan. Archaeological evidence for making flour ( wheat seeds crushed between simple millstones) dates to at least 6000 BC. Rye flour is a constituent of bread in central and northern Europe. For example, the word cornmeal often connotes a grittier texture whereas corn flour connotes fine powder, although there is no codified dividing line.Ĭorn flour has been important in Mesoamerican cuisine since ancient times and remains a staple in the Americas. Meal is either differentiable from flour as having slightly coarser particle size (degree of comminution) or is synonymous with flour the word is used both ways. The phrase fleur de farine meant "the finest part of the meal", since flour resulted from the elimination of coarse and unwanted matter from the grain during milling. The English word flour is originally a variant of the word flower, and both words derive from the Old French fleur or flour, which had the literal meaning "blossom", and a figurative meaning "the finest". coli and needs to be cooked like other foods. The CDC has cautioned not to eat raw flour doughs or batters. For example, the word cornmeal often connotes a grittier texture whereas corn flour connotes fine powder, although there is no codified dividing line. Rye flour is a constituent of bread in central and northern Europe.Ĭereal flour consists either of the endosperm, germ, and bran together (whole-grain flour) or of the endosperm alone (refined flour). Corn flour has been important in Mesoamerican cuisine since ancient times and remains a staple in the Americas. Cereal flour, particularly wheat flour, is the main ingredient of bread, which is a staple food for many cultures. Flours are used to make many different foods. Flour is a powder made by grinding raw grains, roots, beans, nuts, or seeds.
