Flour bleaching agents

Flour Bleaching Agents and Bread Improvers. Freshly milled flour contains carotenoid pigments that cause the flour to have a yellow color. In addition, when the flour is made into dough the product is sticky and unmanageable. As the flour ages, a natural process takes place which turns the flour white and improves its baking qualities. Because the natural process takes quite a bit of time, additives are used to speed up the process. 

Azodicarbonamide is used as a blowing agent in the plastics industry. Moreover, it is used as a food additive, not - as may be suspected - as a yeast replacement, but as flour bleaching agent. However, in some countries its use as food additive is not allowed. 

Benzoyl peroxide [94-36-0], is a bleaching agent that is typically added at the flour mill at a level between 0.015 and 0.075%. This additive... 

If flour is allowed to age for about a month, its natural yellowish color will fade to white due to the effects of oxygen. This aging period can allow insects to spoil the flour, and is often eliminated by adding bleaching agents, such as benzoyl peroxide. 

Benzoyl peroxide is used as a bleaching agent in wheat flour, but its more familiar use is as a powerful acne medication that can lay claim to the following benefits ... 

Wheat flour typically becomes white by means of normal oxidation in air during a few weeks of storage. To speed up the process, manufacturers use benzoyl peroxide as a bleaching agent. Sulfur dioxide is a reducing bleaching agent that is used to preserve dried fruits.

Benzoyl peroxide is used as an initiator for polymerization of acrylates (including dental cements and restoratives) and other polymers as a bleaching agent for flour, fats, oils, waxes and milk used in the preparation of certain cheeses in pharmaceuticals for the topical treatment of acne in rubber curing and as a finishing agent for some acetate yams (Anon., 1984 Lewis, 1993 Medical Economics Co., 1996 United States Food and Dmg Administration, 1997). 

There are several methods of manufacturing is on a commercial scale, for instance the calcination of oxalic add blended with potassium chloride, treatment of sodium chlorite with chlorine, or of sodium chlorate with sulphur dioxide in the presence of concentrated sulphuric add. Chlorine dioxide is utilized as a strong bleaching agent for cellulose, paper, flour, oils and such like, as well as a solvent for removing lignin from wood pulp.
