Abstract: Systems and methods for manufacturing maltodextrin and protein nutritional products from rice are disclosed. Some embodiments include: milling hydrated rice, digesting with an ?-amylase enzyme to form a mixture of maltodextrin and protein, and separating the protein and maltodextrin from one another.

Abstract: Some embodiments relate to metal binding agents and chelators for preparing food products (including nutritional supplements) from vegetable and plant sources for the reduction of heavy metal content. In some embodiments, the plant sources include rice. In some embodiments, when bound or complexed to a metal to be removed, the metal binding agents and chelators are can be separated (e.g., filtered, etc.) from the food material during processing. In some embodiments, the metal binding agents and chelators are organic certifiable.

Abstract: Some embodiments relate to metal chelators for preparing food products (including nutritional supplements) from vegetable and plant sources having reduced metal content. In some embodiments, the plant sources include rice. In some embodiments, when complexed to a metal to be removed, the metal chelators are water soluble and can be separated (e.g., rinsed, etc.) from the food material during processing. In some embodiments, the metal chelators are organic certifiable.

Abstract: A process for converting, separating and removing conversion products from grain endosperm using a contained reaction vessel to effect conversions and extractions. The process minimizes particulate interference with equipment, thereby lowering operating and capital expense. Successive conversion and extraction processes reuse major system parts in each step.

Abstract: A method of separating an aqueous ethanol mixture from an active ethanol fermentation broth. The method comprising the steps of (a) supplying a selected fraction of the fermentation broth to a first reverse osmosis membrane separation stage to generate a dilute aqueous ethanol permeate and a reduced ethanol content fermentation broth retentate; (b) recycling the reduced ethanol retentate to the active fermentation broth; (c) supplying the aqueous ethanol permeate to a second membrane separation stage to generate a concentrated aqueous ethanol retentate and a dilute aqueous ethanol permeate; and (d) recycling the dilute aqueous ethanol permeate of step (c) to the active ethanol fermentation broth. An additional step of processing the concentrated aqueous ethanol retentate to remove water optionally follows.

Abstract: A system and method for fermenting substrates using a continuous processing system, including agricultural and industrial by-products such as dairy products, cellulosic-based products, and sugar-based products, into useful target products such as ethanol. One preferred system includes at least two reaction vessels and one or more membrane filters. The reaction vessels may each contain a mash with substrate and fermentation microorganisms useful in converting the substrate to the target product. The membrane filter(s) may be located downstream from reaction vessels and used to separate the mash into a retentate and a permeate. The microorganisms may be generally retained in the retentate and returned to their originating reaction vessel, while the permeate, not including the microorganisms, may be introduced to the next reaction vessel in series.
