The invention discloses a
solid dispersion of beta-1, 3 / alpha-1, 3-
glucan as well as a preparation method and application thereof, and belongs to the technical field of
biology. The
solid dispersion of beta-1, 3 / alpha-1, 3-
glucan provided by the invention comprises beta-1, 3 / alpha-1, 3-
glucan and
polysaccharide, wherein the beta-1, 3 / alpha-1, 3-glucan and the
polysaccharide are compounded to form the
solid dispersion; the
mass ratio of the beta-1, 3 / alpha-1, 3-glucan to the
polysaccharide is 3: (1.5-3); the polysaccharide comprises one or more of
curdlan,
carrageenan and
microcrystalline cellulose; the solid dispersion of beta-1, 3 / alpha-1, 3-glucan has lower
viscosity and higher
solubility in application, and the stability of a beverage can be effectively improved; and the preparation method is simple and easy to implement and suitable for industrial
mass production, and the obtained solid dispersion does not contain a surfactant, is
safer and has smaller
irritation.
