Chemicals added to White Flour

After the bran and germ are removed from wheat grains, what’s left is mainly the starch in the endosperm.  Try making bread from corn starch and you’ll see why chemicals are added to flour to make it behave like flour again.

These chemicals give flour a bad taste and odor, so restaurants and baked goods hide this by adding a lot of salt, sugar, and fat.

The Food and Drug Administration (FDA) has approved dozens of chemicals that can be added to flour, but you won’t see them in the ingredients list

I’d like to know all of these chemicals are safe, but 62,000 chemicals that were invented before the 1976 Toxic Substances Control Act remain untested.   Since then, the Environmental Protection Agency has only tested 200 of the 80,000 chemicals used in the USA.  Even if a chemical is safe, it might not be when combined with others.

Here are just some of the chemicals added to white flour

Emulsifiers to strengthen dough, soften crumb, make the texture consistent, etc.

lecithin, sodium stearoyl lactylate (SSL), glycerol monostearate, diglycerides, sucrose esters of fatty acids, monoglyceride and lecithin enriched in lysophospholipids, sucrose palmitate (sucrose ester), citrate ester of monoglyceride (citrate MG), polysorbate (polyoxyethylene sorbitan monostearate), carboxymethyl cellulose (CMC), stearyl palmityl tartrate, sodium alginate, kappa carrageenan

Dough Conditioners (also known as dough improvers)

diacetyl tartaric acid ester of monoglyceride (DATEM), calcium stearoyl-2-lactylate, calcium carbonate, monocalcium phosphate

Oxidizing chemicals

Whitens and brightens bread color quickly, strengthens dough-gluten bonds to handle high-speed machinery, give volume.  In cake flour, chlorination helps get better results where more sugar is used than flour (Kent).  Germany and France only allow one oxidizing chemical: L-ascorbic acid.

Flour maturing (oxidant)

Azodicarbonamide   In the UK it’s believed it may cause asthma, and may cause allergic reactions in those allergic to azo compounds.

L-ascorbic acid (vitamin C)

   Bleaching (oxidant):    Benzoyl

   Chlorine, chlorine dioxide. Chlorine (gas) is always used to bleach cake flours and mixes.    Chlorine is not allowed in most European countries.

   Nitrogen peroxide. Discontinued everywhere but the USA and Australia.

acetone peroxide. Not permitted in the U.K.

   Dough Conditioners (oxidant, increases volume)

   Potassium Bromate. This chemical is known to cause cancer in animals. In California   there must be a warning label if this is in the baked goods (Weiss, Amendola).  It’s added to make the dough stronger and quickens mixing and fermentation. It isn’t allowed in Canada, Europe, Brazil, Peru, Nigeria, etc.

Calcium bromate, calcium iodate, calcium peroxide, calcium dioxide, calcium sulfate, ammonium sulfate, potassium persulfate, ammonium persulfate, potassium iodate

Reductants & enzymes reduce the mixing time so more baked goods can be produced.

            Reducing agents: L-cysteine, glutathione (GSH), bisulfite salts.

Enzymes: amylase, lipoxygenase, transglutaminase (strengthens dough)

Preservatives:  Calcium Propionate

BHA and BHT Butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) may cause cancer 

Food colorings: Blue 1, Blue 2, Red 3, Green 3, Yellow 6. All of these are linked to cancer.

Center for Science in the Public Interest says Acesulfame-K, artificial colorings blue 1, red 3, yellow 6, and transfats in baked goods should be avoided because they are “Unsafe in amounts consumed or very poorly tested and not worth any risk.”  .

One or more of: increase dough yield, resiliency, improve texture and shelf life, thicken, gel, stabilize: xanthan gum, guar gum, gum arabic, locust bean gum, hydroxypropyl methylcellulose (HPMC), high ester pectin

Leavening agents: calcium phosphate

Mold inhibitors: salts of propionic acid

About Alice

I've milled and baked with whole grains for many years, because whole grains are delicious, and white flour is missing the nutrition that protects you from cancer, stroke, heart disease, diabetes and many other diseases. Plus it's a good emergency food.

    It is heard that a chemical pronounced like “aloksaan” is used to bleach wheat flour to make maida (a white flour used to make the Delicious food item called Porotta in Kerala which is believed as a cause of cancer.
