Bread Manufacturing

Scary Ingredients Used in Bread Manufacturing

Bread was a big part of our childhood. Toast with butter for breakfast, bakery-fresh bagels and croissants, sandwiches on white bread for lunch—some form of bread accompanied each meal. Whatever the shape or size, though, it was always white bread made with refined flour.

But over the past 30 years, bread has come a long way. As recently as 15 years ago, 80 percent of bread sold in the U.S. was white bread.(1) Today, it’s a much different story. We’re buying more whole grain bread and less white, and in 2010, for the first time, sales of whole wheat bread surpassed that of white bread—$2.6 billion compared with $2.5 billion.(2) Thanks to education, availability, and improved labeling (like stamps and logos indicating healthier products), whole grains have become a top priority with consumers.

If you’ve ever made bread from scratch, you know that it’s made with simple ingredients: flour, water, yeast, and salt. Commercially-made bread, though, often includes a long list of ingredients. As consumer awareness improves, commercial bread manufacturers are beginning to remove some dangerous ingredients from their breads, such as high-fructose corn syrup, and adding health-promoting ingredients such as ancient grains, omega-3 rich flaxseeds. While doing research it was discovered that there are many hidden ingredients in bread (or in the ingredients used to make bread) that consumers don’t get to see since they are not clearly identified on food labels.

Don’t Judge a Bread by its Color

Most of us are aware that it isn’t enough to buy bread based on color. Bread that is brown might simply be made with refined flour colored with caramel color or with some whole grain flour mixed in. When buying bread, the term, ‘100% whole wheat’ or ‘100% whole grain’ should be listed as the first ingredient. What does this mean? This indicates that all three parts of the whole grain kernel—the bran (the outer layer), the germ (the part that germinates), and the endosperm (the inside of the grain, which is mainly starch) are included.

Flour that is not whole grain is made with the endosperm only. The bran and germ are removed—and along with them, 70 percent of the nutrients (B vitamins, minerals, and all of the fiber). Removing the germ and milling flour extends the shelf life of bread products, delaying their rancidity. At this point, the flour is refined and unbleached. To make it white, it is bleached.

Although unbleached flour naturally whitens and softens over a 12-week period, commercial bakeries prefer to use bleached flour, which ages in only 48 hours! Bleaching produces a brighter white color and improves the flour’s texture, making it more user-friendly. According to CooksIllustrated.com, “Typically, all-purpose flours are bleached with either benzoyl peroxide or chlorine gas.”

The various chemicals used to bleach flour (oxidizing agents) may include:

- Benzoyl peroxide (banned in the EU and China)
- Calcium peroxide (banned in the EU and China)
- Chlorine (banned in the EU)
- Chlorine dioxide gas (banned in the EU and Australia)
- Azodicarbonamide (banned in Singapore, the EU and Australia)
- Potassium bromate (banned in the EU, Canada, China, Nigeria, Brazil, South Korea, Sri Lanka, Peru and more)
- Calcium bromate (banned in the EU and Canada)
- Nitrogen dioxide (banned in the EU and Australia)

But with the convenience come health hazards. Let’s take a closer look:

Benzoyl Peroxide & Calcium Peroxide

Benzoyl peroxide has a long history of use in the food industry as a bleaching agent added to flour, whey (specifically whey that has been colored using annatto), and milk for cheese making (mostly cheddar and Italian cheese). A premix of 32 percent benzoyl peroxide and 68 percent cornstarch (genetically modified cornstarch) is used in bleaching flour.

In the U.S., benzoyl peroxide is considered GRAS (generally regarded as safe) when it’s used as a bleaching agent,but both benzoyl and calcium peroxide have been banned in China and the E.U. In the E.U., benzoyl peroxide is banned for cosmetic use as well (the same stuff that’s used in acne creams and teeth-whitening kits).

If your motivation for buying whole grain bread is higher nutritional value, you might be surprised to learn that benzoyl peroxide is a powerful oxidant that destroys nutrients in flour, especially vitamin A and the B vitamins (which include folic acid). This is ironic, because those ‘in the know’ buy whole grain bread for B vitamins!

Benzoyl peroxide has been linked with liver problems, and according to INCHEM’S (Chemical Safety from Intergovernmental Organizations) research, “the chemical possesses properties indicating hazards to human health (sensitization, effect on testes weight, fetal body weight and skin tumor promotion activity)” that should be further researched.

We found calcium peroxide listed on the ingredients label of Nature’s Own Honey 7 Grain Bread. This bread also includes mono- and diglycerides, azodicarbonamide, DATEM, and the soy (soybean oil, soy lecithin, soy grits) and corn grits it contains are most likely genetically modified (GMOs).

Nature’s Own Whitewheat® Bread

Ingredients: Whole wheat flour, water, enriched flour (wheat flour, malted barley flour, niacin, reduced iron, thiamin mononitrate, riboflavin, folic acid), wheat gluten, brown sugar, honey, sunflower seed kernels, yeast, rolled oats, contains 2% or less of each of the following: salt,soybean oil, cultured wheat flour, vinegar, dough conditioners (may contain one or more of the following: sodium stearoyl lactylate, calcium stearoyl-2-lactylate, mono- and diglycerides, calcium peroxide, calcium iodate, DATEM, ethoxylated mono- and diglycerides,azodicarbonamide), wheat bran, rye flakes, barley flakes, soy flour, buckwheat flour, bulgur wheat, cracked wheat, triticale, yellow corn grits, millet, soy grits, ground flaxseed, brown rice flour, calcium sulfate, soy lecithin, wheat starch, enzymes.

Chlorine

For decades, chlorine has been added to our public drinking water and swimming pools, table salt, and is even found in certain food product (sucralose, for example). The use of chlorine to bleach flour is an industry standard, which means it’s likely used to make the flour in the bread, bagels, cake, cookies, croissants, donuts, cereals, pasta, and any other bleached and refined flour products that we buy. Most of us don’t question the long-term safety of chlorine exposure, but like the many other additives in our food supply, chlorine does have adverse affects on human health.

In flour-making, chlorine gas undergoes an oxidizing chemical reaction with some of the proteins in the flour, producing a by-product called alloxan. In the laboratory, alloxan is a chemical that scientists use to intentionally produce diabetes in healthy experimental animals. It causes diabetes by creating a large amount of free radicals to form in pancreatic beta cells–the cells that produce insulin – destroying them and causing diabetes!(9)

Unless the wheat flour and any flour products that you buy clearly state that they are unbleached, it is best to avoid any refined flour products, especially if there is diabetes in your family.

Potassium bromate (food additive E924)

Perhaps the most dangerous ingredient used in bread-making, potassium bromate is used as a flour improver to strengthen dough and produce a higher rise in bread.

Consumption of potassium bromate has been linked to damage of the kidneys and nervous system. The International Agency for Research on Cancer considers the chemical a possible carcinogen,(10) and it has been banned from use in food products in the EU, Canada, China, Nigeria, Brazil, South Korea, Sri Lanka, Peru and other countries.

Although the FDA strongly urges bread manufacturers to avoid using potassium bromate, it is not banned in the U.S. (since its use was sanctioned prior to the Delaney clause of the Food, Drug and Cosmetic Act in 1958, which states: “the Secretary of the Food and Drug Administration shall not approve for use in food any chemical additive found to induce cancer in man, or, after tests, found to induce cancer in animals.”).(11) In California, products using bromated flour require a warning label.

Avoid any bread products listing ‘bromated wheat flour’ or ‘potassium bromate’ in the ingredients list. We found potassium bromate— along with trans fats, dough conditioners and calcium propionate—in Di Rienzo Sliced Italian Bread sold at Walmart.

Di Rienzo Sliced Italian Bread

Ingredients: Bleached Flour (Bromated Wheat Flour, Malted Barley Flour, Flour, Niacin, Iron, Potassium Bromate, Thiamine, Riboflavin, Folic Acid), Water, Base (Salt, Vegetable Oil, Shortening (Partially Hydrogenated Soybean, Cottonseed And/Or Canola Oil), Dextrose, Sugar, Soy Flour, Cornstarch, Dough Conditioners (Vegetable Mono And Diglycerides, Ascorbic Acid, L-Cysteine, Fungal Amylase), Yeast, Calcium Propionate, Sesame Seeds (When Apparent)].

Azodicarbonamide (food additive E927):

Azodicarbonamide is liberally used in bread in the U.S., where it is listed as GRAS and can be added to flour at levels up to 45 ppm, but it is banned as a food additive in Singapore, Australia and Europe, where it is considered to be a respiratory additive and a possible cause of asthma.(12, 13, 14)

Azodicarbonamide is used both as a flour bleaching agent and as a flour strengthener, helping to make dough more elastic.(15) Since it is part of the flour making process, it is not always listed on food labels, but you can assume that it’s in most products made from white flour. That includes pasta, cookies, bagels, croissants, cereal, crackers, muffins, pastries, chapatti and more! To avoid azodicarbonamide, purchase bread labeled 100 percent whole wheat that does not contain any added enriched flour, breads and flour-based foods made with organic flour, or gluten-free and wheat-free bread and pasta products. You can count on products from organic suppliers like Rudi’s Organic Bakery to produce azodicarbonamide-free baked goods!

We found azodicarbonamide listed on the ingredients list in many brands of bread (but remember, it isn’t always listed!), including Sunbeam Enriched Old Fashioned Bread, which also contains high-fructose corn syrup, and Healthy Life Soft Style 100% Whole Grain Bread.

Sunbeam Enriched Old Fashioned Bread

Ingredients: Enriched flour [wheat flour, malted barley flour, niacin, iron, thiamin mononitrate (Vitamin B1), riboflavin (Vitamin B2), folic acid], water, high fructose corn syrup, yeast. Contains 2% or less of each of the following: salt, vegetable oil (soybean and/or cottonseed oils), yeast nutrients (calcium sulfate, ammonium chloride, monocalcium phosphate, ammonium sulfate), calcium propionate (preservative), dough conditioners (contains one or more of the following: sodium and calcium stearoyl-2, lactylate, mono- and diglycerides, ethoxylated mono- and diglycerides, calcium iodate, azodicarbonamide, enzymes, ascorbic acid, DATEM, calcium peroxide), wheat starch, corn starch, soy lecithin, soy flour.

Healthy Life Soft Style 100% Whole Grain Bread

Ingredients: 100% whole grain whole wheat flour, water, sugar, wheat gluten, yeast, contains 2% or less of the following: soybean oil, cultured wheat flour, vinegar, salt, honey, dough conditioners (mono & diglycerides, ethoxylated mono-diglycerides, sodium stearoyl lactylate,azodicarbonamide, ascorbic acid, calcium peroxide), yeast nutrients (monocalcium phosphate, calcium sulfate, ammonium sulfate), fumaric acid, wheat starch, soy lecithin.

Ironically, because of the amount of whole grains in this bread, Healthy Life can claim that, “Healthy Life Soft Style 100% Whole Grain Bread is a good source of fiber, which can promote good digestive health and aid in weight loss efforts,” and that it is “heart healthy” and “may reduce the risk of heart disease and certain cancers.” This is very misleading, when the bread contains trans fats (as you’ll see below)—significant contributors to heart disease! Yet Healthy Life is also able to state that the product contains, “No trans or saturated fat; no artificial preservatives; no high fructose corn syrup;” and “no hydrogenated oils.”(16) We’re not impressed. This product most certainly will not contribute to a ‘healthy life.’

Mono- and Diglycerides & DATEM

Thanks to the addition of mono- and diglycerides and the dough conditioner DATEM, the ultimate bread-making short-cuts, processed breads don’t go stale as quickly as all-natural breads do, and when they’re added to dough, they make it possible to bake bread and bread products speedily without the usual efforts required in traditional bread making.

These inexpensive man-made fats have replaced the natural (and costlier) ingredients, lard and butter. By and large, they are by-products of fats and oils processing–including partial hydrogenation, a process that produces trans fats. The FDA requires labeling of trans fats, but only if a food contains more than 0.49 g per serving and only if it comes from triglycerides. Because mono- and diglycerides are not triglycerides, food manufacturers use this as a loophole to use – and to hide – trans fats. Although they provide 9 calories per gram, they are not required to be included in the Total Fat or Calories on a Nutrition Facts label, and they are not identified as trans fats either!.(17)

We found mono- and diglycerides as well as DATEM in most of the breads we looked at, including this one from Sara Lee:

Sara Lee Soft & Smooth White Bread

Ingredients: Enriched bleached flour [wheat flour, malted barley flour, niacin, iron, thiamin mononitrate (Vitamin B1), riboflavin (Vitamin B2), folic acid], water, whole grain [whole wheat flour, brown rice flour (rice flour, rice bran), wheat gluten, skim milk, high fructose corn syrup,sugar, yeast. contains 2% or less of each of the following: butter (cream, salt), calcium sulfate, salt, dough conditioners (may contain one or more of the following: mono- and diglycerides, ethoxylated mono- and diglycerides, sodium stearoyl lactylate, calcium peroxide, DATEM, ascorbic acid, azodicarbonamide, enzymes), guar gum, yeast nutrients (monocalcium phosphate, calcium sulfate, ammonium sulfate), corn starch, calcium propionate (preservative), distilled vinegar, beta-carotene (color), natural flavor, Vitamin D3, soy lecithin, soy flour.

Calcium Propionate

The most commonly-used preservative in commercial bread making, calcium propionate, prevents mold and bacteria growth.(18) A study found that calcium propionate was linked with irritability, restlessness, inattention and sleep disturbance in some children.(19)

It’s in most brands of bread, including Weight Watchers Multi-Grain bread, which also includes mono- and diglycerides, DATEM, polydextrose, azodicarbonamide, GMO soy flour, and the Scary Seven artificial sweetener, acesulfame potassium.

Weight Watchers Multi-Grain Bread

Ingredients: Whole wheat flour, water, wheat gluten, whole buckwheat groats, contains 2% or less of the following: whole amaranth, whole spelt flakes, whole kamut (khorasan wheat), whole quinoa flakes, whole grain buckwheat flour, oat fiber, polydextrose, salt, sugarcane fiber, wheat bran, molasses, soybean and/or canola oil, yeast, sodium stearoyl lactylate, vinegar, calcium propionate (preservative), calcium sulfate,ethoxylated mono- and diglycerides, DATEM, citric acid, azodicarbonamide, acesulfame potassium, soy flour.

Natamycin

Natamycin is an antibiotic (antifungal) that is used in the food industry as a “natural” preservative. It is used in products such as cheeses, sausages, cottage cheese, sour cream, yogurt and packaged salad mixes. While the European Food Safety Authority (EFSA) has concluded that the use of natamycin as a food additive has no relevant risk for the development of resistant fungi, there has not been sufficient research to identify whether or not natamycin alters bowel bacteria or whether it can contribute to antibiotic resistance. Why take a chance? If you see it listed on a food label, avoid it.

Nature’s Own Whitewheat® Bread

Ingredients: Unbleached enriched flour (wheat flour, malted barley flour, niacin, reduced iron, thiamin mononitrate, riboflavin, folic acid), water, sugar, fiber (may contain soy, oat,cottonseed, and/or cellulose), wheat gluten, yeast, contains 2% or less of each of the following: calcium sulfate, soy flour, salt, calcium carbonate, soybean oil, cultured wheat flour, dough conditioners (contains one or more of the following: sodium stearoyl lactylate,calcium stearoyl lactylate, monoglycerides, mono- and diglycerides, calcium peroxide, calcium iodate, DATEM, ethoxylated mono- and diglycerides, azodicarbonamide, enzymes, ascorbic acid), vinegar, guar gum, citric acid, ammonium sulfate, monocalcium phosphate, sodium citrate, soy lecithin, niacin, iron (ferrous sulfate), thiamine hydrochloride, riboflavin, folic acid, natamycin (to retard spoilage), 102111

Sodium Stearoyl-2-Lactylate (SSL)

The food additive sodium stearoyl-2-lactylate (E 481, SSL) and calcium stearoyl-2-lactylate (E 482, CSL) are used as dough strengtheners in bread, waffle and pancake products. SSL is also used in icings, fillings, puddings, snack dips and cheese substitutes. CSL is sometimes used to replace fat in baked goods. Both SSL and CSL are used in various dairy-based spreads.(20) They have been deemed safe by most health organizations, including The Center for Science in the Public Interest; nonetheless, when purchasing baked products such as bread, choose a brand with the least amount of ingredients.

Key Take-Aways

If health is your prime objective when buying food, purchasing bread made with 100 percent whole grain flour is an excellent improvement over refined and bleached flour products, but it isn’t enough. Here are some tips to keep in mind next time your shopping for bread:

- Look for the term, ‘100% whole wheat’ or ‘100% whole grain’ to be listed as the first ingredient. Simply looking for the word ‘Unbleached’ is not enough as it indicates that the flour has not undergone a bleaching process, but it is still refined.
- Bleached flour has been treated with chemicals that could lead to adverse health effects, including diabetes. These chemicals may not be listed on the label, so your safest bet is to avoid any foods made with white flour.
