    A method for preparing nontoxic, edible proteinic concentrates adapted also for human nutrition, is disclosed according to which undesirable compounds such as polyphenols (e.g. chlorogenic and caffeic acids) are complexed by aluminum salts to prevent oxidizing these polyphenols to quinones. It is important that aluminum be constantly kept in soluble form to prevent it from being precipitated together with the proteins when protein-precipitating acidification is carried out. Citric acid has been found to be the best complexing agent.

    (54) METHOD FOR OBTAINING PROTEIN IEOLATE FROM PLANT RAW MATERIALS
    one
    The invention relates to the food industry and relates, in particular, to the technique of obtaining protein protein from vegetable raw materials, preferably from the low-fat flour of a subpericone.
    A known method of obtaining a protein isolate from plant raw materials involves extracting the raw material with a solution of sodium hydroxide in the presence of salt, aging, separating the extract, precipitating the protein with citric acid at the isoelectric point, isolating the target product and its substance 11.
    However, upon receipt of the protein isolate, the extraction of the raw material is carried out in the presence of polyphenoxy compounds, in particular chlorogenic and caffeic acids, which are toxic and are the main obstacle to the direct use of such flour in man's writing.
    The aim of the invention is the removal of toxic components, such as chlorogenic and caffeic acid.
    This goal is achieved in that according to the method of obtaining a protein isolate from plant raw material, preferably from low-fat flour, sunflower seed, which involves extracting the raw material with a solution of hydrochloric acid in the presence of salt, aging, extracting the extract, precipitating the protein the isoelectric point, the isolation of the target product and its drying, as the salt used in the extraction of the hydroxide protein —CYu sodium, use an aqueous solution of aluminum sulphate, and after precipitation
    15 of its protein is repeated (extracted with sodium hydroxide solution and precipitated with mineral acid,
    Present during extraction, the apyuminate ion forms complexes with sp20 tobiphenols, i.e. with coffee chlorogenic acids, and prevents their oxidation to quinones.
    From the extract, proteins are isolated by precipitation at an isoelectric point (pH 5), using

    35 Formula of the invention A method for producing a protein isolate from plant material, preferably from nonfat flour of sunflower seeds, which involves extraction of the feedstock with a solution of sodium hydroxide in the presence of sapi, exposure, separation of the extract, precipitation of the protein with pi-, monoic acid at an isoelectric point, isolation of the target product and its drying, which is characterized by the fact that, in order to remove toxic components, such as xporogenic and caffeic acids, as a sop used in extraction! protein with sodium hydroxide, an aqueous solution of aluminum sulfate is used, and after precipitation of the protein it is re-extracted with sodium hydroxide solution and precipitated with citric acid.
