  • Method for preparing an aqueous solution of beta-glucan
    Patent number: 10273514
    Abstract: The presently claimed invention is directed to a method for the preparation of an aqueous solution comprising at least one beta-glucan comprising at least the steps of a) fermentation of at least one fungal strain in an a fermentation broth, b) addition of at least one acid to the fermentation broth to adjust the pH to a value in the range of ?2.0 to ?4.0 and c) filtration of the fermentation broth to obtain an aqueous solution comprising the at least one beta-glucan and at least one beta-glucan that is obtained by this method.

  • METHOD FOR CONCENTRATING BETA-GLUCANS
    Publication number: 20180273647
    Abstract: The presently claimed invention relates to a method for concentrating a beta-glucan comprising at least the following steps: (a1) contacting an aqueous beta-glucan solution having a concentration [c1] with at least one precipitating agent p1 to obtain a precipitated beta-glucan in a solvent mixture comprising water and the at least one precipitating agent p1; (b1) separating the precipitated beta-glucan from the solvent mixture comprising water and the at least one precipitating agent p1 to obtain a precipitated beta-glucan having a concentration [c2]; and (c1) applying force to the precipitated beta-glucan of (b1) to obtain a precipitated beta-glucan having a concentration [c3].
