Rice Hulls

Rice hulls are the protective outer layers of the rice grain. They are removed from brown rice during the milling process. Hulls are typically considered a byproduct and are often used for animal feed or as a source of fiber.

Rice hulls are sometimes used as an anti-caking agent in powdered food products, helping to prevent clumping. They can also be used as a source of dietary fiber in certain food applications. You might find them in spice blends or as a processing aid.

In the US, rice hulls are generally recognized as safe (GRAS) by the FDA when used as intended. They are primarily composed of fiber and are not typically associated with significant health effects at the levels found in food. International bodies like JECFA have evaluated similar fibrous materials, but specific evaluations for rice hulls may vary.
