What is bleaching and maturing agents?
BLEACHING OR MATURING AGENTS: These agents are added to flour during or after milling to improve the color and baking qualities. Most work by “oxidizing” some critical component of the flour. CHELATING AGENTS trap trace amounts of metal atoms that would otherwise cause food to discolor or go rancid.
What are maturing agents?
Maturing agents are additives that change the baking properties of flours. Maturing agents are added to flour by the miller and are found in many dough conditioners that can be added by the baker. Some maturing agents strengthen gluten, while others weaken it.
What is bleaching in food additives?
Flour bleaching agent is a food additive added to flour in order to make it appear whiter (freshly milled flour has a yellowish tint) and to oxidize the surfaces of the flour grains and help with developing of gluten. Flours treated with bleaches and improving agents generally show higher loaf volume and finer grain.
How starch is bleached?
It is obtained by treatment of food starch, in accordance with good manufacturing practice, with peracetic acid and/or hydrogen peroxide, or sodium hypochlorite or sodium chlorite, or sulfur dioxide or alternative permitted forms of sulfites, or potassium permanganate or ammonium persulfate.
Why is bleached flour banned in Europe?
Bright White Flour In the US, flour is bleached using food additives including chlorine, bromates, and peroxides, which have been banned in Europe and many other countries since the early 1990s. The reason is that these chemicals may cause cancer and were never really intended to be eaten in the first place.
What is maturing of flour?
Maturing implies aging, thus strengthening the dough forming properties of the flour, including gas retention (loaf volume) and overall processing tolerance. Freshly milled flour benefits most from ADA addition. As flour ages, its use may not be necessary.
Is chlorine a bleaching agent?
Except to bleach wood pulp and flour, chlorine itself is rarely used as a bleaching agent. The principal form of hypochlorite produced is sodium hypochlorite. Other hypochlorites include calcium hypochlorite and bleach liquor, bleaching powder and tropical bleach.
What is bleaching agents in agriculture?
The reducing agents generally used in bleaching include sulfur dioxide, sulfurous acid, bisulfites, sulfites, hydrosulfite (dithionites), sodium sulfoxylate formaldehyde, and sodium borohydride. These materials are used mainly in pulp and textile bleaching.
What are bleached starches?
1403 – Bleached starch: A modified starch is a starch that has been chemically modified to allow the starch to function properly under conditions frequently encountered during processing or storage, such as high heat, high shear, low pH, freeze/thaw and cooling.
What are starch derivatives?
The term “starch derivative” includes those modifications which change the chemical structure of some of the d-glucopyranosyl units in the molecule. These modifications usually involve oxidation, esterification, or etherification. In Australia, for example, wheat starch is commonly used.
Why did they start bleaching flour?
More About Bleached Flour Bleached flour uses bleaching agents (commonly benzoyl peroxide and chlorine gas, among others) to speed up the flour’s aging process. This results in a whiter, finer-grain flour with a softer texture. Some people with sensitive palate can notice a difference in taste with bleached flour.
