Abstract

A composition of yeast polysaccharides including β(1,6)-glucans, preferably also mannans and α-glucans. The yeast polysaccharides are extracted from yeast cell wall fragments. Typically, the β-glucans are β(1,6)-glucans. Also, a method for obtaining such a composition, including at least one step of fractionating a composition of yeast cell walls and extracting an insoluble fraction, and at least one step of extracting a soluble fraction from the insoluble fraction obtained in step a). Further, a composition with a human or veterinary therapeutic objective, for the treatment of gastrointestinal pathologies associated with pathogenic microorganisms, as well as to its non-therapeutic use for improving intestinal comfort.
