Thermal alkaline degradation was used with impact shear in the first stage, followed by alkaline peroxidation and shear in the second stage. The degradation products were removed in the liquid centrifugates at each stage. The maize fiber gels are characterized by high viscosities and hydration capacities. After drying, they can be reconstituted by using shear forces to the original gel form. The fiber gels were also co-dried with hydrophilic materials to make their reconstitution to gel form easier. The alkaline extracted hemicellulose effluents from the fiber gel preparation, including the second stage peroxidized extract, were purified and used as a co-dried hydrophilic material. Also, an amylodextrin, oat flour hydrolysate, was used as a hydrophilic material. The cellulosic gel is capable of reducing caloric content in a wide variety of foods. More nutritious foods were prepared with greatly decreased saturated and trans fat contents. Worldwide license of the technology is available. |
