Identifying Important Parameters for a Continuous Bioscouring Process

Compared to a bioscouring process in the batch mode, a continuously operating process requires relatively short processing steps. This study focusses on minimizing the required enzymatic incubation time. It is clear that the presence of a sufficient level of surfactant is of major importance in obtaining a satisfying level of water absorbency in a limited time frame. Surprisingly, it is also clear that, although essential, the level of pectin degradation is less important. The most crucial factor in the whole bioscouring process is the removal of the enzyme-weakened cuticle compounds in the rinsing phase. Rinsing at high tem peratures in the presence of surfactant and chelator is most efficient.
