Abstract: A method by means of which both the sensory appeal and the dietary fiber content can be increased in a range of food products. By assuring that a suitable dietary fiber component is substantially completely converted to a fully-dispersed colloidal sol, such a material in this state can produce beneficial changes in the sensory and functional properties of certain foods to which it is added while being otherwise undetectable by the consumer. “Suitable” dietary fiber being on that is capable of becoming the dispersed phase in a colloidal sol, and that neither has nor reacts to produce any objectionable taste, aroma, color or mouth-feel in the food to which it is added.
