NEW YORK (AP) -- Subway says it's in the process of removing a chemical from its bread as part of an ongoing effort to improve its recipes.
The announcement comes after a food blogger launched a petition this week asking the sandwich chain to stop using the ingredient. A representative for Subway says the change was underway before the petition was launched.
"The complete conversion to have this product out of the bread will be done soon," Subway said in a statement, without providing further details.
Vani Hari, who runs the FoodBabe.com site, has targeted other food companies including Kraft and Chick-fil-A for the chemicals in their products.
In the latest petition targeting Subway, Hari noted that the azodicarbonamide used in its bread is also used to make yoga mats and shoe rubber.
