The nutrition facts label for traditional pink Peeps has a short ingredient list: Sugar, Corn Syrup, Gelatin, Red #3, Potassium Sorbate, Natural Flavors, and Carnauba Wax. It also states that Peeps are gluten-free. As far as being vegan, all of these ingredients check out, except for one. Gelatin is an ingredient that is often not vegan, or even vegetarian. It is often made by a process of boiling animal skin, tendons, ligaments, and bones. Definitely not vegan, right? Well, it can be hard to tell if gelatin is made this way just by the label because some gelatin, like in Trader Joe's Marshmallows, is made from a type of seaweed instead. However, that's unfortunately not the case with Peeps. On the Just Born website it states that "the gelatin used in our marshmallow candies is derived from pork products." The verdict? Marshmallow Peeps are not vegan.
