Historically, millers would age flour for several weeks to achieve white flour. This natural oxidation, however, was an irregular process requiring considerable time and space. Today, the bleaching process is accomplished using chemical bleaching agents. Flours treated with these bleaching agents must be labeled as bleached flour.

The process of tooth whitening lightens the colour of a tooth. Tooth whitening can be achieved by either changing the intrinsic colour or by removing and controlling the formation of extrinsic stains. The chemical degradation of the chromogens within or on the tooth is termed as bleaching. Hydrogen peroxide (H 2 O 2) is the active ingredient most commonly used in whitening products and is ...
