Physico-chemical properties of protein-bound polysaccharide from Agaricus blazei Murill prepared by ultrafiltration and spray drying process

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 degrees C and showed relatively good enough for their thermal stabilities.
