In biscuit making, use of chlorinated flour reduces the spread of the dough, and provides a "tighter" surface. The changes of functional properties of the flour proteins are likely to be caused by their oxidation. In countries where bleached flour is prohibited, microwaving plain flour produces similar chemical changes to the bleaching process ...
"Bleached flour" is "refined" flour with a chemical whitening (bleaching) agent added. "Refined" flour has had the germ and bran, containing much of the nutritional fibre and vitamins, [citation needed] removed and is often referred to as "white flour". Bleached flour is artificially aged using a "bleaching" agent, a "maturing" agent, or both.
Next, a chemical bleaching process is used to give the flour a whiter color. This bleaching step, usually with chlorine or benzoyl peroxide, destroys many of the original nutrients that were present in the flour. The final flour product contains a smaller portion of the original nutrients that were present in the seed prior to processing.
A dough conditioner, flour treatment agent, improving agent or bread improver is any ingredient or chemical added to bread dough to strengthen its texture or otherwise improve it in some way. Dough conditioners may include enzymes , yeast nutrients, mineral salts, oxidants and reductants , bleaching agents and emulsifiers . [ 1 ]
The flour used in white breads is often bleached further—by the use of flour bleaching agents such as potassium bromate, azodicarbonamide, or chlorine dioxide gas to remove any slight natural yellow shade and make its baking properties more predictable.
Skip the loaf of pre-sliced white bread during your next grocery trip. “There is minimal nutritional value in processed white bread (the one that comes in packages),” says Dr. Lopez-Jimenez.
Young shoots of a plant are covered to exclude light to prevent photosynthesis and the production of chlorophyll, and thus remain pale in color. Different methods used include covering with soil ( hilling or earthing up) or with solid materials such as board or terracotta pots, or growing the crop indoors in darkened conditions.
Bleached flour is a white flour treated with flour bleaching agents to whiten it (freshly milled flour is yellowish) and give it more gluten-producing potential. Oxidizing agents are usually employed, most commonly organic peroxides like acetone peroxide or benzoyl peroxide , nitrogen dioxide , or chlorine .
