Title (EN) PHENOLIC COMPOUND PURIFICATION
(FR) PURIFICATION DE COMPOSE PHENOLIQUE
Abstract:
(EN) A process for the production of purified isoflavones from a starting material resulting from a biological source is disclosed. The starting material includes at least one isoflavone in its conjugate form and at least one impurity. The process includes adjusting the concentration of the starting material in an aqueous medium so that the concentration of the isoflavone conjugates therein is greater than about 20 percent (%) of saturation, but smaller than saturation, whereby there is formed an isoflavone purified solution comprising a purified isoflavone conjugate and an isoflavone-depleted precipitate containing the impurity, and wherein the isoflavone-depleted precipitate contains, after washing, less than about 20 percent (%) of the isoflavone conjugate present in the starting material. The process also includes separating the isoflavone purified solution from the isoflavone-depleted precipitate. The process also includes separating the isoflavone from the isoflavone purified solution. A purified polyphenol produced from a starting material resulting from a biological source is also disclosed. A process for the production of purified isoflavones from a starting material is also disclosed.
(FR) L'invention concerne un procédé de production d'isoflavones purifiées à partir d'une matière de départ provenant d'une source biologique. La matière de départ contient au moins une isoflavone dans sa forme conjuguée ainsi qu'au moins une impureté. Le procédé consiste à ajuster la concentration de la matière de départ dans un milieu aqueux de telle sorte que la concentration des conjugués d'isoflavone qu'il contient soit supérieure à environ 20 pour-cent (%) de saturation, mais inférieure à la saturation, de sorte qu'est formée une solution d'isoflavone purifiée contenant un conjugué d'isoflavone purifié et un précipité appauvri en isoflavone contenant l'impureté, et le précipité appauvri en isoflavone contient après lavage moins d'environ 20 pour-cent (%) du conjugué d'isoflavone présent dans la matière de départ. Le procédé consiste également à séparer la solution purifiée d'isoflavone du précipité appauvri en isoflavone. Le procédé consiste également à séparer l'isoflavone de la solution purifiée d'isoflavone. Un polyphénol purifié, produit à partir d'une matière de départ issue d'une source biologique est aussi décrit. L'invention concerne aussi un procédé de production d'isoflavones purifiées tirées d'une matière de départ.
