Soy Fiber in Food: Uses, Benefits and Sourcing Guide
a versatile functional ingredient. Derived from non-GMO soybean hulls and cotyledon cell walls, soy fiber offers an excellent balance between functional performance and sensory compatibility. Unlike coarser fibers that create gritty textures or overly fine powders that clump easily, properly milled soy fiber is widely adopted in industrial food processing. Soy fiber consists primarily of cellulose, hemicellulose, pectin, and minor amounts of protein. It is typically a light beige to off-white powder with a neutral odor, containing approximately 70–90% total dietary fiber (predominately insoluble). Key functional properties include: Water-holding capacity: 7-8 times its own weight Fat-binding capacity: 2–3 times its own weight Swelling volume: 10–15 mL/g These properties enable moisture retention, texture improvement, and cost reduction across various food systems.
