Rodney L. Ausich has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for the isolation and purification of lycopene crystals
    Patent number: 5858700
    Abstract: A process for isolating and purifying lycopene crystals from a biological lycopene source is disclosed. A lycopene-containing oleoresin is saponified in a composition of propylene glycol and aqueous alkali to form lycopene crystals. Crystallization is achieved without the use of added organic solvents. The crystals are isolated and purified. The substantially pure lycopene crystals so obtained are suitable for human consumption and can be used as a nutritional supplement and as an additive in food.
    Type: Grant
    Filed: April 3, 1997
    Date of Patent: January 12, 1999
    Assignee: Kemin Foods, LC
    Inventors: Rodney L. Ausich, David J. Sanders
  • Biosynthesis of zeaxanthin and glycosylated zeaxanthin in genetically engineered hosts
    Patent number: 5684238
    Abstract: DNA segments encoding the Erwinia herbicola enzymes geranylgeranyl pyrophosphate (GGPP) synthase, phytoene synthase, phytoene dehydrogenase-4H, lycopene cyclase, beta-carotene hydroxylase, and zeaxanthin glycosylase, DNA variants and analogs thereof encoding an enzyme exhibiting substantially the same biological activity, vectors containing those DNA segments, host cells containing the vectors and methods for producing those enzymes, zeaxanthin and zeaxanthin diglucoside by recombinant DNA technology in transformed host organisms are disclosed.
    Type: Grant

  • Process for the formation, isolation and purification of comestible xanthophyll crystals from plants
    Patent number: 5648564
    Abstract: A process for forming, isolating and purifying xanthophyll crystals, preferably lutein from marigold flower petals, zeaxanthin from wolfberries or capsanthin and capsorubin from red pepper, is disclosed. A xanthophyll diester-containing plant extract is saponified in a composition of propylene glycol and aqueous alkali to form xanthophyll crystals. Crystallization is achieved without the use of added organic solvents. The crystals are isolated and purified. The substantially pure xanthophyll crystals so obtained are suitable for human consumption and can be used as a nutritional supplement and as an additive in food.
