History of Bleached Flour
The practice of bleaching flour dates back to the late 19th century, when flour mills began to use chlorine gas to whiten and soften flour. The process was initially developed to improve the appearance and texture of flour, making it more appealing to consumers. At the time, flour was often coarse and grayish in color, which made it unattractive to bakers and home cooks. By bleaching the flour, manufacturers could produce a brighter, more refined product that was easier to work with and more visually appealing.
The Mechanism of Bleaching
The bleaching process involves treating flour with a chemical agent, such as chlorine or bromine, to remove impurities and improve its color and texture. The most common method of bleaching flour is through the use of chlorine gas, which is applied to the flour in a controlled environment. The chlorine reacts with the flour’s natural pigments, breaking down the molecules and resulting in a whiter, more refined product. The bleaching process can also involve the use of other chemicals, such as benzoyl peroxide or azodicarbonamide, which are designed to improve the flour’s strength and elasticity.
