that is practically unexploited, although abundant, due to its highly
perishable condition Acknowledging the fact that specific characteristics of the
substrate, enzymes contained in the preparation and reaction time are involved in a successful clarification process this study aimed to establish the adequate conditions for the application of pectinolytic formulations produced by Aspergillus
oryzae and Aspergillus niger strains, in submerse and solid-state cultures, respectively. For this purpose, temperature and reaction time were observed in clarification experiments with apple, grape, blueberry, and butia palmfruit juices. Additionally, pH influence on total pectinolytic activity in the experimental extracts was assayed.
