If you’ve planked on a yoga mat, slipped on flip-flops, extracted a cell phone from protective padding or lined an attic with foam insulation, chances are you’ve had a brush with an industrial chemical called azodicarbonamide, nicknamed ADA. In the plastics industry, ADA is the “chemical foaming agent” of choice. It is mixed into polymer plastic gel to generate tiny gas bubbles, something like champagne for plastics. The results are materials that are strong, light, spongy and malleable.
As few Americans realized until Vani Hari, creator of FoodBabe.com, spotlighted it earlier this month, you’ve probably eaten ADA. This industrial plastics chemical shows up in many commercial baked goods as a “dough conditioner” that renders large batches of dough easier to handle and makes the finished products puffier and tough enough to withstand shipping and storage. According to the new EWG Food Database of ingredients in 80,000 foods, now under development, ADA turns up in nearly 500 items and in more than 130 brands of bread, bread stuffing and snacks, including many advertised as “healthy.”
EWG researchers who are constructing the database found that ADA is listed as an ingredient on the labels of many well-known brands of bread, croutons, pre-made sandwiches and snacks, including Ball Park, Butternut, Country Hearth, Fleischman’s, Food Club, Harvest Pride, Healthy Life, Jimmy Dean, Joseph Campione, Kroger, Little Debbie, Mariano’s, Marie Callendar’s, Martin’s, Mother’s, Pillsbury, Roman Meal, Sara Lee, Schmidt, Shoprite, Safeway, Smucker’s, Sunbeam, Turano, Tyson, Village Hearth and Wonder.
This synthetic additive has been largely overlooked because it is not known to be toxic to people in the concentration approved by the federal Food and Drug Administration – 45 parts per million. According to the World Health Organization, workers handling large volumes have reported respiratory symptoms and skin sensitization, but ADA has not undergone extensive testing of its potential to harm human health.
One thing is clear: ADA is not food, as food has been defined for most of human history. It is an industrial chemical added to bread for the convenience of industrial bakers. In centuries past, flour fresh from the mill had to age several months before it could be kneaded into dough and popped into the oven. But in 1956, a New Jersey chemical, pharmaceuticals and engineering firm called Wallace & Tiernan, best known for inventing a mass water chlorination process, discovered that ADA caused flour to “achiev[e] maturing action without long storage.” The result, the firm’s patent application stated, was commercial bread that was “light, soft and suitably moist, yet suitably firm or resilient, and that [had] crusts and internal properties of a pleasing and palatable nature.” The FDA approved ADA as a food additive in 1962. It is not approved for use in either Australia or the European Union.
In the early 1990s, ADA became the preferred dough conditioner of many American commercial bakers as a result of California’s Proposition 65, which went into effect in 1987. This law required California authorities to list certain chemicals in food as “possibly dangerous to human health.” Potassium bromate, then a common dough conditioner, was found to be carcinogenic in test animals and made the Prop 65 list in 1991. ADA was widely adopted as a safer substitute.
