Summary This study was conducted to develop the powder material and investigate the various physico‐chemical properties of protein‐bound polysaccharide with different molecular weight from Agaricus blazei Murill using ultrafiltration and spray‐drying process. Powder properties of the three spray‐dried powders were very different based on their molecular weights. The inlet temperature had less influence than pump rate on particle size of spray‐dried powders. The moisture content of powders was increased with increasing pump rate and decreasing inlet temperature. Among these powders, SD‐1, the molecular weight of which is below 10 kDa, was less flowable by internal cohesion. The decomposition temperature for the powders was in the range of 200–400 °C and showed relatively good enough for their thermal stabilities.
