Evaluation of spray-drying process of commercial liquid α-amylase
The aim of this work was to investigate the effect of inlet and outlet air temperature on the proceeding of spray drying and α-amylase inactivation. Relative enzyme activity after drying was higher when higher inlet and outlet air temperature were used. Increasing of inlet and outlet air temperature led to faster water evaporation, decreasing of final water content in dried material and to increasing of energy lost during process.
