The Application segmentation of the Plant Sourced Protein market is organized into Food & Beverage, Animal Feed, Dietary Supplements, Functional Ingredients, and Other uses, forming the core of the market taxonomy. Food & Beverage commands the largest slice, roughly 55% of market revenue, as manufacturers integrate plant proteins into meat analogues, dairy alternatives, and protein‑enriched snacks to meet consumer demand for sustainable nutrition. Animal Feed represents about 25%, where soy and pea proteins replace traditional soymeal, enhancing feed efficiency and reducing reliance on animal‑derived inputs. Dietary Supplements account for 12%, leveraging isolated protein isolates for sports nutrition, weight management, and clinical nutrition products. Functional Ingredients contribute 6%, encompassing hydrolysates, peptides, and textured vegetable proteins that deliver specific functional benefits such as solubility, foaming, or gelling in processed foods. The remaining 2% falls under Other, including applications in cosmetics, pharmaceuticals, and biodegradable materials. This application‑centric breakdown underpins the overall market size by allocating revenue streams and growth trajectories across distinct end‑use categories, a key focus of Plant Sourced Protein segmentation analysis.
