FIELD: amino acids, polymers. n SUBSTANCE: invention describes poly-γ-glutamic acid (PGG) of the super-high molecular mass, its average molecular mass is above 5000 Da. This substance is prepared by irradiation of PGG of the super-high molecular mass in form of an aqueous solution by using gamma-radiation, and foodstuff product comprising PGG of the super-high molecular mass. Also, invention describes a composition promoting to absorption of mineral substance in form of solution and comprising PGG of the super-high molecular mass or copolymer of PGG of the super-high molecular mass with polyamino acids carrying the positive charge, and mineral substance. PGG of the super-high molecular mass can be used as an agent enhancing absorption of the mineral substance. n EFFECT: valuable properties of polymer. n 10 cl, 6 dwg, 7 ex |
