Abstract
Provided are a β-1,3-1,6-glucan powder having high solubility in water, a glucan-containing composition using the powder or the like, a method for producing the β-1,3-1,6-glucan powder, an inclusion complex, a method for producing the inclusion complex, and a method for recovering a guest molecule. The β-1,3-1,6-glucan powder has a saturation solubility in water at 25° C. of from 1.0 to 20.0 % by mass. The β-1,3-1,6-glucan powder is such that in a particle size distribution of β-1,3-1,6-glucans, determined by subjecting the β-1,3-1,6-glucan powder to dynamic light scattering measurements, a particle size of a peak representing a largest volume fraction is in a range from 5 nm to 15 nm, and a volume fraction of a peak outside of the particle size range from 5 nm to 15 nm is 30 % or less of the volume fraction of the peak having the largest volume fraction.
