Compositions and methods for producing sorghum nutraceuticals

Abstract

An apparatus, composition, and method are provided for processing red and black sorghum seed. The process includes mechanically separating the seed into bran and endosperm-rich material, combining the bran with ethanol, filtering the resulting mixture through a resin-based filtration system, and evaporating the ethanol to produce an extraction product. Also disclosed are an apparatus and method for producing a sorghum isolate composition comprising a 3-DA concentrate in which the 3-DA concentration is at least twice that of whole seed, and the lead concentration is below 200 ppb. In certain embodiments, the mercury concentration is below 100 ppb, the cadmium concentration is below 100 ppb, or the arsenic concentration is below 200 ppb. Additional embodiments achieve 3-DA concentrations at least 100 times higher than whole seed, at least 1,000 times higher than whole seed, at least 2,000 milligrams per kilogram, or any combination of these levels.
