  • Patent number: 9732302
    Abstract: Systems and methods are provided for separating high value by-products, such as oil and/or germ, from grains used for alcohol production. In one embodiment, a method for separating by-products from grains used for alcohol production includes, subjecting milled grains to liquefaction to provide a liquefied starch solution including fiber, protein, and germ. The germ is separated from the liquefied starch solution. The separated germ is ground, e.g., to a particle size less than 50 microns, to release oil to provide a germ/oil mixture. Then, prior to fermentation, the oil is separated from the germ/oil mixture to yield an oil by-product. The pH of the germ/oil mixture can be adjusted to about 8 to about 10.5 and/or cell wall breaking enzymes or chemicals may be added to help release oil from the germ. In one example, the oil yield is greater than 1.0 lb/Bu.

  • Patent number: 9382558
    Abstract: This invention relates to a new process for making fatty acids directly from a feedstock consisting of phytoplankton in water without the need to a) thermally separate, dewater and dry the phytoplankton, and b) extract the immobilized lipids. Our method is much less expensive than the current practice of making fatty acids from phytoplankton, because we bypass the costly and energy intensive operations associated with a) dewatering and drying the biomass, and b) extracting the immobilized lipids. As such, this invention greatly enhances the economic viability of making biofuels and bioproducts from phytoplankton.

  • Patent number: 5281732
    Abstract: An improved low temperature process for extracting oil from oil-bearing materials by extracting the oil-bearing material in an extraction zone with a normally gaseous solvent selected from propane, butane, and mixtures thereof. As the resulting solvent/oil mixture is passed through the bed of extracted oil-bearing material, from the extraction zone, and to a separation zone, it is done so under conditions that will maintain the solvent in liquid form. The resulting extracted materials have substantially more of their protein and vitamin value intact when compared with similar materials extracted by more conventional high temperature methods. The present process is also a lower energy consuming process than more conventional, extractive processes.

  • Patent number: 5166375
    Abstract: The antioxidant is safe for human health, has excellent antioxidation activity and is suitably utilized for preventing oxidation of unsaturated fatty acids, esters of unsaturated fatty acids and various kinds of products comprising these acids and esters. The oxidation resistant polyunsaturated oil is made by giving strong antioxidation activity to polyunsaturated oils, such as polyunsaturated fatty acids, esters of polyunsaturated fatty acids and polyunsaturated fats.The antioxidant comprises musizin and tocopherol as the effective components. The oxidation resistant polyunsaturated oil and fat of the invention is characterized in that an antioxidant comprising musizin as the effective component is added to a polyunsaturated oil.

  • Patent number: 5155244
    Abstract: A method of solubilizing a first compound in a second medium where the first compound has a limited solubility in the second medium. In particular, the method comprises reacting the first compound with the second medium. By this reaction, a product is formed whereby an active component of the first compound is covalently incorporated into the second medium.The first compound and second medium each contain at least one reactive group which will react with a reactive group of the other. In addition, the first compound comprises at least one antioxidant which will be covalently bonded to and thus effectively solubilized in the second medium by the reaction.The second medium comprises glyceride derivatives, silicones, fluorocarbons and alkoxylates containing reactive groups such as hydroxy, amino, carboxyl, ester, or amides.
