The present invention is comprised of an increased dietary fiber method and treatment for processed foods to add dietary fiber to processed foods, control water activity (aw) and increase the pliability of the high fiber ingredients during mixing, blending and forming operations. The method adds soluble fiber ingredients to the processed food mixtures to provide consumers with a high fiber source to meet recommended daily Adequate Intake of fiber. The method additionally reduces non-fiber carbohydrate sources and sugar alcohols providing other beneficial physiological effects and helps to control water activity by using liquid soluble fiber to bind water adding to the shelf life of the processed food products. The treatment increases the pliability of the ingredient mixtures to more thoroughly combine, mix and blend the ingredients. The treatment continues to provide increased pliability of the completed product mixture during a product forming process.
