Abstract: A process is disclosed for preparing a detergent powder containing enzymes where the enzymes are extracted from a fermentation broth with a salt and surfactant mixture and directly agglomerated with detergent paste and dried to form the detergent powder. The process results in a two phase system where the enzyme is extracted into the surfactant rich phase and the second phase is salt rich. The process is especially useful for whole or clarified fermentation broths.
