Impossible Burger is made using a variety of plant-based ingredients. The primary ingredient is soy protein concentrate, which provides the burger’s meat-like texture. It also contains potato protein, coconut oil, sunflower oil, and heme, a protein found in plants and animals that gives the burger its characteristic taste and aroma. Other ingredients include methylcellulose, a plant-based binder, and natural flavors and additives like salt, onion powder, and garlic powder. The burger is free of major allergens like dairy, eggs, and gluten, making it a popular choice for plant-based eaters and those with dietary restrictions.
