from cbsnews.com: Kraft is removing artificial preservatives from its most popular individually wrapped cheese slices, in the latest sign that companies are tweaking their recipes as food labels come under greater scrutiny. The change affects the company’s Kraft Singles in the full-fat American and White American varieties, which Kraft says account for the majority of the brand’s sales. Sorbic acid is being replaced by natamycin, which Kraft says is a “natural mold inhibitor.“… Last week, Subway said it was removing a chemical from its bread after a popular food blogger named Vani Hari started a petition noting the ingredient is also used in yoga mats.
