evidence: The ingredients listed on some food products may sound as though they belong in a chemistry lab rather than in grocery store goods. Propylene glycol is one such example, found in thousands of products from salad dressing to dog food, cosmetics and antifreeze. This synthetic chemical, generally regarded as safe for food use, helps products maintain their moisture, consistency and texture, which is why it’s commonly found in packaged consumables and household products. [...] Many foods containing a laundry list of ingredients also contain propylene glycol. Some of the more common packaged foods containing it include dried soups and seasoning blends, marinades and salad dressings and baking mixes for products such as cakes, pancakes and muffins. In the beverage world, soft drinks, flavored teas, powdered drink mixes and alcoholic beverages may also contain propylene glycol. It is also used in some flavoring extracts for baking, as well as in some types of food coloring. Propylene glycol is also quite common in fast foods, bread-based products, highly processed snack foods, flavored popcorn and cake frosting. Pre-made, mass-distributed baked desserts such as brownies, cakes and cupcakes may also contain this chemical. Even some ice cream flavors contain propylene glycol.
