Tubular fibers are produced from legume hulls such as soybean hulls and combined with food products and/or spices to enhance the flavor and aroma of the food products. The tubular fibers further can be combined with pharmaceuticals and neutraceuticals to establish desired time-release profiles for the pharmaceuticals and neutraceuticals when consumed. The fibers are produced utilizing a method and apparatus that increases the fiber yield and minimizes waste material that needs to be processed prior to be disposed.
