Abstract:
Processes for the production of polyols from sources such as dried distillers grains plus solubles (DDGS) make use of a two-stage reaction scheme. In the first stage, the proteinaceous starting material is reacted with an aminating agent, such as diethanolamine (DEOA), to generate amino-amides and amides. These products are then reacted with an alkoxylating agent, preferably a substituted or unsubstituted epoxide to yield polyols. These polyols may be further reacted with isocyanates to give low-cost rigid polyurethane foams. In alternate forms, lignin may be directly converted to polyols by reaction with an alkoxylating agent, optionally followed by reaction with an isocyanate to produce polyurethanes.

Abstract:
Process equipment for the separation of gluten from wheat starch including gluten process equipment configured to process gluten after the gluten is initially separated from A starch, the gluten processing equipment having a dewatering press configured to dewater gluten and modified gluten process equipment including at least one component selected from the group having a high pressure water wash system located upstream of the dewatering press, a kneader located upstream of the dewatering press, a homogenizer located upstream of the dewatering press, a dispersion tank configured to precipitate fines downstream of the dewatering press, a solids-ejecting centrifuge downstream, and combinations thereof.
Abstract:
High protein expanded products are produced by extrusion with unique blends of ingredients, such as wheat protein isolates, modified wheat starch, salts, gums and moisture. The mixture is extruded in a twin-screw extruder with the temperatures in the range of 50 to 140° C., screw speeds of 250 to 450 rpm and with a back pressure of 350 to 1200 psi for different recipes. A range of expanded wheat crisps and other expanded products with wheat protein contents ranging from 30 to 90% are obtained from this process. The expanded products have good cell structure with varying cell sizes when viewed under a microscope. This process can be used to develop a varied range of products such as, wheat crisps, wheat curls, wheat loops etc. The products may be used in nutritional or health bars and other comestible having a high protein and low carbohydrate content.
Abstract:
Composite materials containing non-plasticized, non-gelatinized starch, a compatibilizer and a synthetic resin, such as polyethylene and/or polypropylene, may be used to make wood replacement products for use as construction materials.
Abstract:
Mineral-bound starch products are provided for enhanced absorption of nutrient minerals. The mineral-bound starch products are prepared by binding biologically active minerals to phosphorylated cross-linked starch. The mineral-bound starch products are stable against heating in hot water followed by washing processes, but able to release bound minerals after digestion.

Abstract:
High-protein food additives are prepared by reacting a protein material with L-cysteine, or a derivative thereof, with homogenization and heating. The homogenization and heating is preferably carried out on an aqueously slurry of the protein material and L-cysteine. The homogenized and reacted slurry is then dried to form a powder. The resultant food additive may be incorporated into a wide variety of food products to enhance the physical characteristics thereof.
