  • Patent number: 11805805
    Abstract: The disclosure describes methods for the purification of protein-enriched extracts to provide concentrates and isolates and methods for incorporation of such materials into products. The purification methods are adapted for removal of nicotine and may have other benefits, e.g., lightening the color of the protein-enriched extracts. The methods generally include treatment with peracetic acid or hydrogen peroxide and filtrations. A protein composition in the form of a concentrate or isolate is provided, the protein composition including RuBisCO, F2 fraction proteins, or combination thereof extracted from a plant of the Nicotiana species, wherein the protein composition is characterized by relatively low nicotine content.

  • Publication number: 20230056300
    Abstract: The disclosure describes methods for the purification of protein-enriched extracts to provide concentrates and isolates and methods for incorporation of such materials into products. The purification methods are adapted for removal of, e.g., chlorophyll and may thus provide lightening the color of the protein-enriched extracts. The methods generally include treatment with peracetic acid or hydrogen peroxide and filtrations. A protein composition in the form of a concentrate or isolate is provided, the protein composition including RuBisCO, F2 fraction proteins, or combination thereof extracted from a plant material.

  • Publication number: 20220287356
    Abstract: The present disclosure describes methods of obtaining and/or deriving proteins from plants of the Nicotiana species and methods for incorporation of such proteins into various products. For example, a method for obtaining a protein-enriched material from a plant of the Nicotiana species or portion thereof is provided, comprising: extracting one or more proteins from the plant material into a solvent to form a liquid protein-containing extract; separating a solid extracted plant material from the liquid protein-containing extract; clarifying the liquid protein-containing extract to form a clarified protein-containing extract and a solids fraction; and treating the clarified protein-containing extract so as to provide a protein-enriched material comprising at least about 60% protein by weight.
