Pea protein and its starches have been used in pet food for many years, but interest in their application is rapidly growing. A key driver of this trend is the rising demand for non-grain pet foods, which started in the U.S. and is now expanding globally. As a plant-based protein, pea protein is widely used in pet food, aquafeed, and animal feed, often serving as a substitute for meat, fish, or soy in pet formulations.
