What is Bleached Flour?
Bleached flour is a type of refined flour that has been treated with chemicals to improve its texture, appearance, and shelf life. The bleaching process involves exposing the flour to gases such as chlorine or bromine, which helps to whiten the flour and remove any impurities. This process also helps to strengthen the gluten in the flour, making it more suitable for baking.
The Production Process of Bleached Flour
The production of bleached flour involves several steps. First, the wheat is harvested and cleaned to remove any impurities. The wheat is then ground into a coarse flour, which is sifted to remove any bran or germ. The resulting flour is then bleached using a gas such as chlorine or bromine. The flour is then packaged and distributed to bakeries and households.
Chemicals Used in the Bleaching Process
The chemicals used in the bleaching process have raised concerns about the safety of bleached flour. Chlorine gas, which is commonly used in the bleaching process, can react with the natural oils in the flour to form compounds such as aldehydes and ketones. These compounds have been linked to a range of health problems, including cancer and respiratory diseases.
