  • Method for preparing a proteinic isolate from sunflowerseed meal using aluminum salts
    Patent number: 4212799
    Abstract: 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.
