The objective of the investigation was to describe changes in the morphology and selected physical properties of protein hydrolyzate powders with maltodextrin as a carrier. The powders investigated were obtained in a process of spray drying. Two inlet air temperatures (160 degree C and 200 degree C) and three raw material fluxes (0,9, 1,18, and 1,28 cubic cm/s were used. The highest moisture content in powder was obtained at a temperature of 160 degree C and a 1,28 cubic cm/s flux of raw material. The increased feeding flux of raw material and the drying temperature did not significantly impact the loose density value obtained. The performed screen analysis of powders showed the increase in the particle size along with the increase in the feeing flux of raw material and in the drying temperature
