Disclosed are methods for separating non-soy plant materials to produce a fat-enriched fraction, a reduced-fat plant extract, reduced-fat plant protein compositions, a crude oil, plant gums, a degummed oil and a protein-fat sediment. Also disclosed are food products containing or prepared from the reduced-fat extracts, fat-enriched fraction, gums, oils, protein-fat sediments and reduced-fat protein compositions.

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 one or more of ash, metal salts, alkaloids, particulates, heavy metals, and other impurities and/or contaminants from extracts, as well as modifying the sensory characteristics (e.g., odor, color, and/or taste characteristics) of extracts. The methods generally include diafiltration, treatment with functionalized resins, and supercritical extraction. 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 one or more of: an ash content of less than about 15% by weight; a nicotine content of less than about 10 g/g, and a heavy metal content of less than about 60 g/g.

Treatment of dried perennial ryegrass with aqueous citrate ion from sodium citrate chelates calcium from the grass which improves extracting juice from the grass. Addition of ascorbic acid to the aqueous solution decreases enzymatic browning of the juice. The juice is centrifuged and filtered. Microscopic examination of the centrifuged and filtered juice that has been stained with methylene blue demonstrates a cellulose content less than extracted wheat grass. Processing the dried perennial ryegrass can be achieved without electricity. Extraction of nutrients from perennial ryegrass may help alleviate world food shortages and may promote peace.

This document relates to materials and methods for the production of protein. For example, proteins having a low flavor or low color profile and food products comprising the same.

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.
