Abstract: The invention generally relates to a method for fractionating plant material into valuable components including beta-glucan. The method uses an organic solvent and water instead of water alone, acidified water and/or aqueous alkali as a solvent for the slurrying of a grain flour. In addition to concentrating beta-glucan, other product fractions produced by the method include starch concentrate, and organic solvent solubles. If enzyme treatments are used, other product fractions include dextrin, protein hydrolysates and organic solvent solubles. The process is particularly effective in concentrating beta-glucans in a state close to its native form from the endosperm of barley and oat grains.

Abstract: A method for treating a living organism to increase nutrient ingestion. The step of the method are first treating a fluid stream for use by at least one living organism, in a surface tension modification generator (STMG) at a first pressure with a frequency minimize hydrogen bonding of the fluid forming a reduced surface tension stream. The next step is flowing the reduced surface tension stream through a port reducing the first pressure to a second pressure and adding oxygen. After oxygen is added, then flow the reduced surface tension stream with oxygen at the second pressure into an inner chamber. The next step is flowing the reduced surface tension stream and oxygen from the inner chamber through a plurality of funnels disposed in a wall of the inner chamber creating a turbid zone in an outer chamber, and wherein nano-sized oxygen particles are dissolved into the stream.
