In recent months, major food companies such as Kraft Heinz, Nestle and Conagra Brands have pledged to eliminate petroleum-based synthetic dyes in coming years. Walmart took its news a step further by identifying other kinds of food additives in its phase-out timeline. Those include synthetic dyes, titanium dioxide, azodicarbonamide, propylparaben, potassium bromate and phthalates, a chemical used to make plastic flexible. But some of the 11 artificial food dyes detailed by Walmart were already banned, proposed to be banned or haven’t been used for years, including Red No. Scott Morris, Walmart’s senior vice president of private brands food, consumables, and manufacturing, told The Associated Press that 90% of Walmart’s private label foods don’t contain synthetic dyes.
