But close behind it is the myth that the white stuff on your baby carrots is chlorine. After baby carrots are cut from regular-sized (though sometimes irregularly shaped) carrots, they are usually rinsed in a very diluted chlorine solution to kill any lingering bacteria. But the “white blush” or “carrot blush” you see on baby carrots is unrelated to chlorine, mold, or any other harmful substance. While regular carrots have a relatively thick skin to keep water contained, baby carrots are more exposed. In other words, the white stuff is often just evidence of dehydration.
