What are soy fibers?
Soy fibers are the fiber-rich residues that remain after oil and proteins have been extracted from soybeans. They are primarily added to foods to increase fiber content, but also possess important functional properties. For example, they improve texture, enhance moisture retention, and aid in the emulsification of oil and water. Soy fibers are classified as dietary fibers and contribute to health because they are not broken down by human enzymes, while supporting intestinal function and other physiological processes. The fibers are largely insoluble, with a small proportion of soluble fibers, making them versatile for various product applications with dual functionality.
